3. OPERATIONAL MODES 3.1. Manual Mode In the manual mode, the user operates the controller using the front panel of the visualization module. The engine is manually started and stopped using the START and STOP buttons.



Pushing the START button activates the engine starting process. Pushing the STOP button once stops the engine, with a cooling down cycle. Pushing the STOP button twice stops the engine inmediately, without cooling down phase.



WITH cooling WITHOUT cooling



NOTE:  In manual mode, the safety devices of the controller remain activated, and if an anomaly is detected, an alarm status is triggered. In manual mode, the device ignores all external requests previously programmed (scheduler or external start input).



3.2. Automatic mode In automatic mode, M7 device constantly controls the genset operation. In some situations, that can be programmed to supply power, the controller starts the generator. As programmable starting conditions of the genset with the breaker activation, could be considered: •• External start. •• Manual override (Configuration table parameters 110, 120 and 121). •• Start scheduler (only optional M7C).

4. WORKING MODE



4.1. Operating ENGINE 4.1.a. Starting the engine The engine works in the following way, once the controller detects an activation condition: •• Delay in the starting: Once the external start condition is detected and before going on with the engine starting process in auto mode, a delay in the engine starting can be programmed (parameter 409 Times table). The AL output is active during this delay before the engines starting process. •• Engine pre-heating phase. The M7 controller activates the pre-heating output (PR) for a programmed time (parameter 402 Times table). •• Engine enabling (engine control output). Engine running enable is made using PC output depending of M7 configuration (parameter 106 Configuration table value 0 and 2). •• Engine starting (START). For a programmed period of time (Times table parameter 403), the cranking output of the M7 device is activated, waiting to detect, at least, one of the programmed starting conditions. The possible engine starting conditions could be: -- Generator voltage (table Configuration parameter 102). M7 controller considers started engine condition when generator voltage exceeds a given value (Thresholds table parameter 314). -- Battery charge alternator voltage (table Configuration parameter 103). M7 controller considers started engine condition when generator voltage exceeds a given value (Thresholds table parameter 315). -- Engine speed (table Configuration parameter 104). M7 controller considers started engine condition when the engine speed exceeds a given value (Thresholds table parameter 316). Engine speed is calculated using a magnetic pick-up mounted on the flywheel; to activate the pick-up calculation through the engine ring gear, the number of teeth of the gear must be introduced (Thresholds table parameter 317). In case of the number of teeth is “0” the engine speed as started condition is disabled and the frequency of the pick-up will be calculated through the generator frequency using the frequency/speed rate: 50Hz/1500 rpm, 50Hz/3000 rpm or 60 Hz/1800 rpm (table Configuration parameter 8). -- Low oil pressure (table Configuration parameter 105). It is not advisable to use the low oil pressure signal as a way to detect if the engine is running, but it is useful as a stopped engine condition, in order to avoid engaging the starter while the engine is running. Exception for this rule is engines which have self-powered sensors.



12 | 



If in a programmed time the starting of the engine is not detected, the control board waits (Times table parameter 401) before attempting a new cranking process. Start failure alarm will be triggered after a specified number of attempts without detecting any starting condition (Thresholds table parameter 301). In the starting cycle, the excitation of the battery charge alternator is activated through the D+ pin temporarily (Times table parameter 406). Once the excitation of the alternator is finished, the measurements module checks iif the battery charge alternator is working properly. The battery charge alternator failure alarm is raised in case of no detection of battery charger voltage in the D+ pin after the battery alternator excitation phase (Alarms table parameter 1010, 1011 and 1012). -- Genset stabilization. Once any of the starting conditions is detected, the controller waits for a programmed stabilization-time of the generator output, before monitoring working variables. -- Nominal condition. Once the stabilization of the engine is reached, the next step is the checking of the signal produced by the generator. In this way, the quality of the signal produced by the generator set is monitored (voltage levels, frequency…). START OPERATING PROCESS. PRACTICAL EXAMPLE NOTE:  Before initiating the stop cycle, it is advisable that the main genset circuit breaker be switched OFF.



PREHEATING: When START button is pressed, the starting cycle will be initiated. At the same time, if the engine has glow plugs, the PR output will be activated for the programmed time. (Times table parameter 402).



CRANKING: After this period of time, the PR output becomes inactive; if programmed, PC output (parameter 106 Configuration table value 0 and 2) or PD (Configuration table parameter 106 value 3) will be activated immediately enabling the engine. 0,5” later cranking output (ARR)

also becomes active until any of the engine started conditions is detected for a maximum programmable length (Times table parameter 403). If M7 does not detect any running engine condition for this length, M7 waits for a time (Times table parameter 401); afterwards and automatically M7 controller will begin a new cranking attempt again. The maximum number of cranking attempts before M7 controller will trigger the START FAILURE alarm is 4 by default (Thresholds table parameter 301).



•• Engine stop. After the cooling down of the engine, M7 controller stops the engine using the PC output according to the programmed stop configuration (Configuration table parameter 106). As a condition of the engine stop, can be selected: -- Generator voltage (Configuration table parameter 102). The engine would be considered stopped when no generator voltage is detected (Thresholds table parameter 314). -- Battery charger alternator voltage: (Configuration table parameter 103). The engine will be considered stopped when no battery charge alternator voltage is detected (Thresholds table parameter 315).



ENGINE STARTED: Once the engine running condition is detected, M7 controller waits for a programmable electrical stabilization time (Times table parameter 405) before the genset breaker activation.



ENGINE STABLE: After the stabilization time, M7 controller ends the starting engine process. To stop the starting cycle, just press the STOP button. NOTE:  The starting process is the same either in manual (by pressing buttons) or auto (external start, scheduler or manual override…) mode.



4.1.b. Engine stop The stop engine process is done according to the following process:



-- Engine speed (tabla Configuración parámetro 104). The engine would be considered stopped when no engine speed calculated by the magnetic pick-up in the flywheel is detected. To activate the pick-up calculation through the engine ring gear, the number of teeth of the gear must be set up (Thresholds table parameter 317); in case the programmed number of teeth in the ring gear is “0”, the frequency of the pick-up will be calculated through the generator frequency as per the equivalence-ratio 50Hz/1500 rpm, 50Hz/3000 rpm or 60Hz/1800 rpm.o 60Hz/1800rpm (Configuration table parameter 108). -- Low Oil Pressure (Configuration table parameter 105). The Low Oil Pressure condition considers the engine stopped when it detects that the sensor is closed. Exception for this “Engine Start Detection” option is SCANIA engines and also the sensors which have self- electrical supply. All the programmed stopping conditions must be validated for an interval of time (Alarms table parameter 1071) to consider the engine as stopped. If during 90 seconds is still detecting any condition engine running, the Stop Failure alarm will be activated and M7 controller will attempt another stop procedure again.



ENGINE COOLING DOWN. Once all loads are disconnected (genset breaker turned off), the engine will continue to run for some time during the cooling time (Times table parameter 407). Under particular situations the alarms of the controller may be programmed (Alarms table parameters 1003, 1006, 1009...) to stop immediately without the cooling down of the engine.

STOP OPERATING PROCESS. PRACTICAL EXAMPLE NOTE:  Before initiating the stop cycle, it is advisable that the main genset circuit breaker be switched OFF The genset can be stopped in several ways: 1. Manual: Press STOP button once. The genset stops with cooling down. 2. Manual: Press STOP button tow times. The genset stops without cooling down. 3. Place the activation key in “O” position. The genset stops without cooling down. 4. Automatic: The genset stops with cooling down cycle after the deactivation of the command which automatically started the genset.

4.1.c. Battery charger alternator M7 energizes the battery charger alternator, by means of a triggering pulse of configurable duration (Times table parameter 406) during the strarting engine process through the D+ pin. When this pulse ends, M7 begins testing the voltage made by the battery charge alternator. The voltage produced by the battery charge alternator can be used as starting engine condition (Configuration table parameter 103). For that purpose, M7 expects to measure through D+ pin, voltage values exceeding the alternator voltage detection threshold (Thresholds table parameter 315). M7 can be configured to raise an Alternator Voltage alarm (Alarms table parameter 1010 a 1012) if it is detected a low voltage level provided by the battery charge alternator through D+.



4.2. Generator features Additional genset control features using 3 free programmable outputs of M7: •• Out1: 2A output PD (Configuration table parameter 122). PD configuration is only available if engine configuration is different of PULL/HOLD mode (Configuration table parameters 106, value 3); PD output is used only as HOLD output in the control process of the engine if the engine configuration is: PULL/HOLD. •• Out2: relay output MN (Configuration table parameter 123). MN default manufactured setting is: short circuit and overload electronic protection (value 1). •• Out3: 2A output CON (Configuration table parameter 124). CON default manufactured setting is: genset breaker (value 5).



4.2.a. Electronic protection (overload and short-circuit) •• Any of 3 free programmable outputs can be set up to develop electronic protection feature (Out1, Out2 or Out3) by M7 configuration (Configuration table parameter 122 a 124 value 1). By default, relay Out2 (MN) is programmed as electronic protection feature (Configuration table parameter 123). •• Electronic protection is a characteristic that allows the activation of an output on the controller when the overload and short-circuit alarm is activated. Threshold and conditions of these alarms must be set to fit the charac-



15 | 



teristics of the electronic protection feature (Thresholds table parameter 307 and 308) and (table Alarms parameters 1028, 1029 and 1030 –overload- and parameters 1058 and 1060 –short circuit-). When any of the overload or short-circuit alarms is activated, the output assigned to this function remains active.



4.2.b. Transfer fuel pump Any of 3 free programmable outputs can be set up as Transfer fuel pump feature (Out1, Out 2 or Out 3) by M7 configuration (Configuration table parameters 122 a 124 value 3). Once the transfer pump option is activated, pump output will be automatically active according to the minimum activation level (Thresholds table parameter 326) and will be automatically deactivate according to the maximum activation level (Thresholds table parameter 327). Gauging system for the fuel tank: For an accurate fuel level measurement (needed for the fuel pump and fuel level alarm functions) a calibration of the tank level sender must be done, by having access to both the minimum and maximum parameters of the level sender (Measures table parameters 202 and 203). To adjust the minimum fuel level of the tank it must be set up the parameter 202 of Measures table with the fuel gauge in the lowest tank position. To adjust the maximum fuel level of the tank, it must be set up the parameter 203 of the Meassures table with the fuel gauge in the uppermost tank position.



4.2.c. Dummy load Any of 3 free programmable outputs can be set up as Dummy Load feature (Out1, Out 2 or Out 3) by M7 configuration (Configuration table parameters 122 a 124 value 2). This option makes it possible to activate a charging rack separate from the installation´s load, in order to prevent the generating set from operating without a load or with low-load thresholds, so as to avoid excessive oil consumption in the engine and keep the engine functioning with an optimum load. The programmable output configured as dummy load feature is activated when the genset power consumption is lower than the programmed threshold (Thresholds table parameter 328). The dummy load output is deactivated when the power consumption of the genset is greater than the programmed threshold (Thresholds table parameter 329). Condition for enabling the dummy load output is that the engine must be running and stable.

Chapter  5  Working mode



4.2.d. Started engine output Any of 3 free programmable outputs can be set up as started engine feature (Out1, Out 2 or Out 3) by M7 configuration (Configuration table parameters 122 a 124 value 4). The engine started output controller is activated from the moment any running engine is detected, and it remains active while the engine is running. The started engine output is deactivated when the engine stopping cycle starts. This process includes the cooling of the engine (Times table parameter 407) during the stopping cycle.



4.2.e. Genset breaker Any of 3 free programmable outputs can be set up as genset breaker feature (Out1, Out 2 or Out 3) by M7 configuration (Configuration table parameters 122 a 124 value 5). Genset breaker output is activated after the engine starting condition if the generator electrical signal is stable (Times table parameter 404) from the moment any running engine is detected, and it remains active while the engine is running. The started engine output is deactivated when the engine stopping cycle starts. This process includes the cooling of the engine (Times table parameter 407) during the stopping cycle.



4.2.f. Input 1 detection Any of 3 free programmable outputs can be set up as input 1 detection feature (Out1, Out 2 or Out 3) by M7 configuration (Configuration table parameters 122 a 124 value 6).



4.4. Irrigation pump mode Irrigation mode configuration (Configuration table parameter 119) allows the M7 to work without electrical generator signals (only engine control). It is recommended to use magnetic pick-up in the flywheel to check engine state.



4.5. Engine running timer It is possible to run the engine for a time in manual mode. The use must hold the key for five seconds while the engine is already running to enter in programming time mode. In this mode, the engine running timer will be increased in 5 minutes while the key is pressed until a maximum length of 18 hours. The programmed timer will be displayed in screen. After the programmed engine running time, M7 controller will start a cooling down process of the engine. In order to cancel the programmed running engine timer, it is necessary to press key. So, the stop procedure for engine running the timer condition is: •• 1th



: cancel the engine running timer.



: cooling down stop of the engine (deactiva•• 2 tion of genset breaker); the engine will stop automatically after the cooling down time (Times table parameter 407). nd



: stops immediately the engine without cooling •• 3th down (Times table parameter 407).



The input 1 detection output controller is activated when time the input 1 activation is detected. The deactivation condition can be chosen between a time after (Times table parameter 404 value different of 0) or on the input 1 deactivation (Times table parameter 404 value 0).



4.3. Triphasic electrical configuration with only one current transformer The only one current transformer option (Configuration table parameter 125) allows the M7 controller to measure only one current cannel. M7 controller estimates the total power consumption considering a balanced condition between current channels and multiplying the first phase current by the number of electrical phases of the generator.

M7 inputs and outputs



5.1. Digital Inputs 5.1.a. Presets inputs M7 controller has 5 digital inptus, whose working process is already preset.



External start signal. This function only works when the functions in automatic mode.The input configured as external start forces the starting of the genset if it is working in automatic mode if there are no warnings and the locked scheduler mode is not active (M7C option).



NOTE:  Emergency stop input power off the PC and S1/ PD outputs in order to assure the stop of the engine. In engine models that need an excitation pulse to stop the engine (table Configuration parameter 106 value 2), Emergency stop input MUST be wired to -BAT in order to never disable power of engine control outputs. Likewise, a programmable input (table Configuration parameter 120 or 121), should be set up to provide the emergency stop function without engine control powering off option.



Fuel reserve. Digital signal reporting to the controller that an alarm has been generated due to a failure in the fuel reserve (Alarms table parameters 1019 to 1021).



High temperature.



5.1.b. Programmable inputs



Digital signal reporting to the controller that the thermostat of the engine has detected a failure and sets on an alarm due to the engine high temperature (Alarms table parameters 1001 to 1003).



The M7 controller has 5 digital inputs whose operation can be programmed (Configuration table parameters 120 and 121). The purpose programmable inputs can be configured to take the following behavior:



Low oil pressure.



Manual Override.



Digital signal reporting to the controller that the engine pressure switch has detected a failure and sets on an alarm due to the low oil pressure (Alarms table parameters 1004 to 1006).



This function only works when the M7 controller is in automatic mode.

The input configured as manual override meets the fire safety regulations and accordingly the working genset cannot be interrupted under any condition except overspeed and emergency stop, including alarms or schedule disabling mode (only M7C option).Three different manual override working modes can be configured (Configuration table parameter 110):



Digital signal reporting to the controller that an alarm triggered due to low coolant level (Alarms table parameters 1016 to 1018).



-- 0: Manual override disabling. The manual override process is not managed, despite of having an associated programmable input.



Emergency stop.



-- 1: External start (AE). When the manual override input is activated, M7 controller waits for an External start condition in order to start the genset in override mode. M7 stops the genset when both external start and manual override inputs are inactive.



Digital signal reporting to the controller that an immediate stop without cooling must be done. Emergency stop input disables by powering hardware the engine control in order to force the engine stop process.

M7 inputs and outputs



5.2. Analogic Inputs



Programmable alarms 1 and 2. There are 2 free alarms that can be associated to any of the programmable inputs whose function is to provide additional alarms to the controller and whose working mode is programmable (Alarms table parameters 1079 to 1084).



M7 controller has 3 analog inputs to measure several engine working values. Such analog inputs will allow to portray the engine working process and display its condition, setting on alarms if required, being its working already pre-set. The alarms caused by the analog inputs does not stop the engine, they are only a warning. By default, the alarms raised by analog inputs do not stop the controller (engine warnings), but can be configured to produce the stop, with or without cooling procedure. M7 controller carries out a continuous checking of the installed analog sensors, showing in the visualization module display its values.



Selection of parameters set. There are one additional set of parameters that may be enabled through any of the programmable inputs. Activating the selection of a set of parameters input enables the values which the controller operates (Selector table).



Emergency stop. It is possible to configure a programmable input as an additional emergency stop input in order to provide an emergency stop alarm that does not disable the engine control power (PC and S1/PD outputs). It is mandatory for pulse stop engines (Configuration table parameter 106 value 1).



Fuel level (NC). The fuel level analog input indicates the amount of fuel that lefts in the tank. To fit its working mode, the maximum fuel level in the tank must be set (Measurements table parameter 203), and the same with the minimum fuel level (Measurements table parameter 202). To adjust view section 4.2.2. In the same way, a minimum fuel-in tank threshold (Thresholds table parameter 318) can be fixed, and it will raise an engine warning (Alarms table parameter from 1055 to 1057) when the fuel level is detected under such limits. When any of the programmable outputs is set up as Fuel pump function, it will start the pump to transfer fuel to the tank if the fuel level is detected under the minimum limits (Thresholds table parameter 326). The fuel pump is deactivated when the fuel level is detected over the programmable threshold (Thresholds table parameter 327).



Genset breaker activation. The configuration of a input as genset breaker activation allows the M7 controller to check the correct activation of breaker when the electrical signal of the genset is stable; M7 controller turns off the genset breaker in stopping process including cool down state. M7 controller launches the genset breaker activation alarm when it checks an incorrect state of the input according to the genset breaker output (Alarms table parameters from 1091 to 1093).



19 | 



Oil pressure (P). The oil pressure analog input allows supervising the engine oil pressure. The controller allows to fit its behavior (see appendix II section 10). By programming a threshold, a minimum oil pressure limit can be set (Thresholds table parameter 319) in order to raise an engine warning (Alarms table parameters from 1052 to 1054) when the pressure is detected under such limit.

M7 inputs and outputs



5.4. Preset digital outputs M7 controller has 5 preset outputs (3 high power outputs and 2 digital outputs). Engine temperature (T). The analog engine temperature input allows supervising the engine coolant temperature value. The controller allows the connection of sensors to such analog fitting its behavior (see appendix II section 10). By programming a threshold, a maximum engine temperature limit can be set (Thresholds table parameter 320) in order to raise an engine warning (Alarms table parameter from 1049 to 1051) when the temperature is detected over such limit.



Pre-heating output. (PR). Power Output.



Battery charger alternator voltage (D+).



Engine cranking output.. (ARR). Power Output.



The analog voltage input allows supervising the value of the voltage generated by the genset. Such an input is used to diagnose the possible abnormal working of the alternator when a low voltage level while the engine is on work is detected. Under such condition an alarm signal of the battery alternator will be triggered. (Alarms table parameter from 1010 to 1012).



The engine cranking output (ARR) of the M7 controller is an output connected to a high voltage short-circuitable driver (40 A) which activates the cranking in the engine starting process. The activation of the engine starting remains until any programmed starting condition is detected (Configuration table parameter from 102 to 105) during a maximum programmable length (Times table parameter 403).



In that way, the voltage can be programmed to detect a starting condition (Configuration table parameter 103) by means of setting an alternator voltage threshold for started engine (Thresholds table parameter 315).



5.3. Magnetic pickup (PKC1, PKC2) The pick-up input from the flywheel controls the rotation speed of the engine in revolutions per minute (rpm). To activate the pick-up calculation through the engine ring gear, the number of teeth of the gear must be introduced (Thresholds table parameter 317). In case of the programmed number of teeth is “0” the controller is configured to have not available the pick-up and the rotation speed will be calculated through the genset frequency using the speed equivalence-ratio 50Hz/1500 rpm or 50Hz/3000 rpm and 60Hz/1800rmp or 60Hz/3600rpm (Configuration table parameter 108). M7 controller can be configured to trigger an overspeed alarm (Alarms table parameters from 1022 to 1024) as well as an underspeed alarm (Alarms table parameters from 1025 to 1027) taking into account the mechanical speed given by the pick-up.



20 | 



The pre-heating output (PR) of M7 controller is an output connected to a high voltage short-circuitable driver (40 A) in charge of regulating the glow plug heating procedure of the engine during the starting cycle. The activation time of the pre-heating output is configurable (Times table parameter 402). The pre-heating output can be also used to control the stop pulse for engines with this kind of stop configuration (Configuration table parameter 106 value 2).



Engine control (PC): Fuel output/Engine stop output/ Enable engine/PULL. Power Output. Engine control output (PC) of M7 controller is connected to a high voltage short-circuitable driver (40 A) that controls the state of the engine depending of 4 different configurations (Configuration table parameter 106): •• Fuel output. Engine control output configured as fuel enable output (Configuration table parameter 106 value) is activated 500ms after the pre-heating output is disabled and it is deactivated when M7 controller stops the engine. •• Engine stop output. Engine control output configured as engine stop output (Configuration table parameter 106 value 1) is activated during a programmable time (Times table parameter 408) when M7 controller stops the engine. In this mode, Emergency stop input of M7 controller MUST be connected to –BAT to be disable the unpowering engine control mode; set up the programmable input wired to emergency stop button in order to develop this feature (Configuration table parameter 120 o 121 value 5).

M7 inputs and outputs



5.5. Programmable outputs •• Engine enable. Engine control output configured as engine enable output (Configuration table parameter 106 value 2) is activated before the cranking output activation output and it is deactivated when M7 controller stops the engine. Such mode is used to enable the engine sensors. The pre-heating output will be the responsible of the stopping phase by means of the excitation stop cycle.



M7 controller has 3 programmable outputs whose working mode can be develop some additional genset features (Configuration table parameter 122 to 124). The following outputs are available for programming:



•• PULL/HOLD mode. Engine control output configured as PULL output (Configuration table parameter 106 value 3) is used as a solenoid PULL activation (40 A) for 1 second during engine cranking state. In this mode, programmable PD output (2A) is used as HOLD activation during engine running. In this mode, any other programmable feature of PD output is disabled (Configuration table parameter 122).



•• Out 3 (CON): driver digital output 2A.



•• Out1 (PD): driver digital output 2 A. IMPORTANT: Powering enable by PEM input. •• Out 2 (MC/MNA/MNC): 2 state relay.



As possible outputs configurations, can be found the following: -



Electronic protection (see section 4.2.1)



Battery charge alternator excitation output (D+). Digital output.



Fuel transfer pump (see section 4.2.2)



D+ output of M7 controller is in charge of exciting the battery charge alternator during the starting process for a programmable length (Times table parameter 406).



Dummy load (see section 4.2.4)



Alarm output (AL). Digital output.



Started engine (see section 4.2.5)



The alarm output (AL) is in charge of communicating the different status of the M7 controller. The AL output is activated simultaneously with the flashing of warning LED and buzzer of M7 controller. This output warns about the following status of the M7 controller:



Gen-set breaker (see section 4.2.6) Input 1 detection (see section 4.2.7).



-- External start in auto mode. The alarm output of the device (AL) is activated for a programmable length (Times table parameter 409) before starting the genset by external start input condition in auto mode. The activation of AL output for external start can be done simultaneously of engine cranking (Times table parameter 409 value 0) for a fixed length of 5 seconds or before attempting the engine crank process (Times table parameter 409 value different of 0). -- Alarm notice. Alarm output is activated for a programmable time (Times table parameter 410) if it is detected an active failure or a failure waiting to be acknowledged by the user. If the user presses once the button, the AL output is deactivated. The genset failures that activate the AL output are either alarms which induce the engine stop or warnings which do not stop the engines.

M7 Controller alarms



6. M7 controller alarms M7 controller provides a set of alarms whose working mode can be configured to perform actions or to be shown in the display. M7 controller distinguishes between anomalies which cause the stop of the engine (alarms) and errors which do not stop the engine (warnings). When an alarm or warning is detected, the controller produces an acoustic alarm, at the same time the digital alarm and display flashes; output (AL) activates and the LED this status will remain for a programmable period of time (Times table parameter 410). Alarm led has 3 different states: •• Off: genset state without errors. •• Flashing: almost one active error active alarm.



Number of alarm screens



•• On: no error active alarm, but M7 needs to be reset to erase list of non-active error alarms. To display the list of alarms is necessary to press once the button, allowing the user to check the list of errors. The list of alarms screen displays a maximum of 8 alarms in each; use up and down buttont to navigate between the different alarm list screens. Pressing button erases all no active error condition alarms of this screen. This is the format of the alarm list screen:



22 | 



NOTE:  M7 controller alarms need to be reset by pressing button (except fuel level and fuel reserve alarms), so its mandatory user’s intervention. By default setting: Alarms whose error condition is an engine analog input measure (oil pressure, coolant temperature and fuel level) do not command a genset stop. Alarms whose error condition is an engine digital input (low oil pressure, high engine temperature and low coolant level) commands an immediate genset stop.

6.4. Alarm description



Emergency stop. The emergency stop alarm of the M7 controller is associated to the specific emergency stop digital input (PEM).



High coolant temperature. The high coolant temperature alarm of the M7 controller is associated to the specific high coolant temperature digital input (ATA). The status of such input must be validated for a stabilization time (Times table parameter 413) before the high coolant temperature alarms triggers. ATA input can be configured as normally open or normally closed (Configuration table parameter 113). The high coolant temperature alarm is configured (Alarms table parameter 1001) to be checked: Always. A delay can be set up to wait for checking stable conditions (Alarms table parameter 1002). This alarm is configured (Alarms table parameter 1003) to carry out by default: the immediate engine stop.



Low oil pressure. The low oil pressure alarm of the M7 is associated to the specific low oil pressure digital input (BPA). The status of such input must be validated for a stabilization time (Times table parameter 412) before the low oil pressure alarm triggers. BPA input can be configured as normally open or normally closed (Configuration table parameter 112). The low oil pressure alarm is configured (Alarms table parameter 1004) to be detected: From the started engine condition. A delay can be set up to wait for checking stable conditions (Alarms table parameter 1005). This alarm is configured (Alarms table parameter 1006) to carry out the following action: Immediate engine stop.



PEM input can be configured as normally open or normally closed (Configuration table parameter 115). NOTE:  PEM input activation powers off the engine control outputs (PC and S1/PD) in order to assure the stop of some model of engines (table Configuration parameter 106 value 0 and 3.) PEM input MUST be plugged to –BAT for engine models that need a pulse to be stopped (Configuration table parameter 106 value 1). So, for this pulse stop engine models, Emergency stop feature has to be done by an alternative programmable input (Configuration table parameter 120 or 121 value 5). The emergency stop alarm always stops the engine without cooling. No delay can be associated to that action, as it is immediately executed after the emergency stop input is detected (PEM).



Battery charge alternator failure. The battery charge alternator failure alarm of the M7 controller is associated to the battery charge alternator voltage analog input (D+). The voltage value of such input must be over the voltage threshold of the started engine detection (Thresholds table parameter 315); if not, the battery charge alternator failure alarm is triggered. The battery charge alternator alarm is configured (Alarms table parameter 1010) to be checked from the started engine condition. A stabilization time can be associated to the battery charge alternator alarm (Alarms table 1011) During this time the obtained voltage values must be kept under the started engine detection threshold (through the D+ input) as a condition for the battery charge alternator failure alarm to be triggered. This alarm is configured by default (Alarms table parameter 1012) to be only a warning (do not stop the engine).

Options



8.1.a. Engine variables Depending of the engine control unit, the engine variables that M7J controller can get from J1939 are: •• Coolant temperature.



8.2. Weekly scheduler M7C controller allows the weekly programming of the following events: •• Start.



•• Oil pressure.



•• Locked.



•• Speed.



•• Test (engine running without genset breaker activation).



•• Coolant level. •• Oil pressure.



Users can program up to 5 different events for each day of the week. M7R controller must be in auto mode in order to manage the scheduler.



•• Current fuel consumption. •• Battery voltage.



The scheduler allows to program specific events for each season (winter, spring, summer or autum) or for all the year (see appendix II section 4. Weekly scheduler).



•• Consumed fuel. •• Working hours. •• Inlet temperature. •• Torque.



8.3. Heater



8.1.b. J1939 engine control M7J controller allows 3 different modes of engine control by J1939 (J1939 table parameter 604):



M7T controller regulates the internal temperature in order to assure that the M7T controller temperature never is under 0ºC using an internal sensor and a heater. The present internal temperature is displayed in



•• Mode 0: M7J displays engine measures, alarms and fault log management. •• Mode 1: M7J displays engine measures, alarms and fault log management and speed regulation. •• Mode 2: M7J displays engine measures, alarms and fault log management, speed regulation and replacement of CiU (only VOLVO and SCANIA engines).



8.1.c. Limiter of sudden change in speed M7J controller allows to limit sudden changes in speed using J1939 control mode 1 and 2 (J1939 table parameter 604); in order to limit sudden changes in speed, it is possible to set up a threshold of maximum change of speed in rpm/sec (J1939 table parameter 606). In case of a change of speed over this programmed threshold, M7J controller will adjust the target speed in several steps. Value 0 of this threshold parameter disables this feature, allowing the engine to make a sudden change of speed.

Chapter  13  (Annex IV) Technical data



The USB connector meets with the standard 2.0. To supply the equipment, we recommend a cable with a 1 mm2 section. To realise the wiring cable of 2.5 is due to use mm2 of diameter for the BAT connections, ARR, PR and PC. For the rest of connections mm2 of diameter is recommendable to use cable of 1. The equipment should be insulated or disconnected before making the connection of voltage input and current. There is risk of danger. The measurements module should be assembled in the back of the switchboard, if possible in the center to easily do the wiring, because there are connectors around the entire module. No special ventilation requirements are needed due to the low power consumed by the module. It is necessary to carry out cleaning on the surface of the equipment and the outside with a damp cloth. The equipment is included within the CAT III 600V category for measurements made in the building installation. Should incorporate resources to disconnect the fixed installation according to the regulations of installation. Such resources must have a separation in all poles supplying disconnection under overvoltage category III. The disconnection resources must be accesible to the users. Connect the grounding connection to the negative point of the battery, to the switchboard chassis and to thegenerating sets chassis.



This equipment has risk of danger if handled improperly. Must be installed by trained technical staff. It is necessary to consult the documentation. WARNING: risk of danger.

Chapter  13 (Annex IV) Technical data



The USB connector meets with the standard 2.0. To supply the plaque, we recommend a cable with a 1mm2 section. The equipment should be insulated or disconnected before making the connection of voltage input and current. There is risk of danger. To realise the wiring cable of 2.5 is due to use mm2 of diameter for the BAT connections, ARR, PR and PC. For the rest of connections mm2 of diameter is recommendable to use cable of 1. The measurements module should be assembled in the back of the switchboard, if possible in the center to easily do the wiring, because there are connectors around the entire module. No special ventilation requirements are needed due to the low power consumed by the module. It is necessary to carry out cleaning on the surface of the equipment and the outside with a damp cloth. The equipment is included within the CAT III 600V category for measurements made in the building installation. Should incorporate resources to disconnect the fixed installation according to the regulations of installation. Such resources must have a separation in all poles supplying disconnection under overvoltage category III. The disconnection resources must be accesible to the users. Connect the grounding connection to the negative point of the battery, to the switchboard chassis and to thegenerating sets chassis. This equipment has risk of danger if handled improperly. Must be installed by trained technical staff. It is necessary to consult the documentation. WARNING: Risk of danger.
