In case of alarm follow this procedure:
1. program pump and drive DSP again; maybe software present in flash memory was
corrupted.
2. replace control board.
Alarm on 5 V encoder voltage
-
Eye alarm code: 37
-
Alarm level: 1
-
Alarm cause: Main board K1-14 terminal (5 V output) voltage is lower than 4.3 V.
In case of alarm follow this procedure:
1. verify if 5 V output is grounded, cause an incorrect encoder wiring.
2. verify if 5 V output is grounded, cause any encoder malfunction.
In that case, replace the defective one.
3. replace control board.
Alarm on 12 V output voltage
-
Eye alarm code: 38
-
Alarm level: 1
-
Alarm cause: Main board K1-12 terminal (12 V output) voltage is lower than 10.5 V.
In case of an alarm on 12 V output voltage, follow this procedure:
1. verify if 12 V output is grounded, cause an incorrect wiring to:
-
Accelerator potentiometer
-
Steering sensor
-
buzzer
-
display
2. replace defective device;
3. replace control board.
