The operation values shown on the display give detailed information about the status of the drive and the connected peripherals. With the LCP 102 you can choose these values freel in the Parameter group 0-2*. These values are accessible also when warning and alarm messages are shown. Alarm Reset The reset of an Alarm is possible in either way - The [Reset] Key on the LCP (The [Off] Key is activated simultaneously) - Terminal control (Parameter setting in Group 5-1*) - The automatic reset function (Parameter setting in Group 14-2*) - Reset signal via serial communication (e.g. RS-485 or Profibus) Alarm with Trip lock An Alarm with Trip lock can be reset only after a complete mains off (Display dark). If the drive is equipped with an external 24V supply (D-option), it is enough to switch off mains and then reset the Alarm. The control card remains active, e.g. for serial communication via Fieldbus. After a mains Off/On it is possible to reset an Alarm on the VLT® FC 300 as mentioned above.
Safety note:
To avoid electrical shock hazard- even after the power is disconnected- wait at least as follows before doing service on the frequency converter: (380-500V: 0.25-7.5 kW: 4 Min. / 11-75 kW: 15 Min./ 90-200 kW: 20 Min./ 250-400 kW: 40 Min.) ..\FC300\Alarm-Warn\English\Alarms & Warnings FC 300 SW 5.5x
