Table 1
Detected Faults    
Error Message    Logged    Symtom    Probable Cause    
Main Pump Circt     No     Main pump has reduced power     Controller contact 5 and contact 28 are not connected to the PRV solenoid.    
Controller contact 5 and/or contact 28 are shorted to ground.
The backup switch in turned ON.
Low Battery Voltage     No     Output current may be reduced     Battery voltage is below 17 DCV.    
RPM Setting Diff     No     Irregular electronic regulation may occur     The difference between the requested governor position (controller output contact 10 and contact 34) and the actual governor position (controller input contact 46) is above 3%. There is a problem in the governor actuator, or in the wiring between the controller and the governor actuator.    
RPM Setting High     No     Engine high idle is too high and/or the pump is not destroked soon enough after the RPM difference is increased.     Governor actuator position signal too high.    
Open or shorted supply voltage circuit
Controller input contact 46 (governor position) receives a voltage signal which is below (1%) the minimal voltage recorded during the last calibration: Either the high idle setting has changed or the circuit is shorted to ground.
RPM Setting Low     No     The Engine low idle is too low and/or the pump is destroked too soon after the RPM difference is increased     Governor actuator position signal too low.    
Open or shorted supply voltage circuit.
Controller input contact 46 (governor position) receives a voltage signal that exceeds (1%) the maximum voltage recorded during the last calibration: Either the low idle setting has changed or the circuit is shorted to battery.
Swing Pump Circt     No     Swing pump has reduced power     Controller output contact 6 and 29 are not connected to the PRV solenoid    
Controller output contact 6 and 29 are shorted to ground
The backup switch is turned ON
Low Engn Speed     No     Hydraulic power may be greatly reduced.     Controller input contact 18 and contact 53 receive a signal that is too low    
Engine speed sensor is not adjusted properly or is faulty.
The engine RPM has dropped below 750 25 RPM
High Engn Speed     Yes     Controller may authorize strong engine lugging     The maximum engine RPM is above the acceptable range. Check injection pump high idle screw setting.    
RPM Dial Setting     Yes     Engine always runs at high idle     Controller input contact 45 is either connected to ground or open    
Heavy Lift Circt     Yes     Heavy lift solenoid cannot be activated     Controller output contact 9 and contact 30 are not properly connected to the solenoid.    
Controller output contact 9 and contact 30 are shorted to ground.
Mode Sw Short     Yes     The machine remains in power mode 1     Controller contact
