SERVICE DIAGNOSIS DATA LIST The value indicated in the following tables is a normal value of service diagnosis mode 2 (screen No.31-35) at each operation. Please compare the values, and perform the trouble shoot of the machine. The value of the current of the proportional valve displayed on the screen of service diagnosis mode 2 is set value in the mechatronics controller. Please compare it with the actual measurement value of mode 1 (screen No,8 and 9). Note: - The values in following lists are reference values on the machine with standard attachment. - The value of pressure sensor is calculated taking the variation into accounts. When compared to performance inspection criteria , measure it with the aid of calibrated measuring instrument - The current of proportional valve is not the measured value, but command value. - The measured value should be confirmed by the value in the displayed value for each proportional valve. - The current value of pump proportional valve is reference value because it varies according to pump pressure and adjusted torque value. - The value in display during operation shows the value in steady state, rather than, at start of operation. - Check on machine after sufficiently warning up machine. - The value in display may differ according to software version and machine spesification. Contact our ealer/distributor.
