Diagnostic Faults:
The following is a list of the diagnostic faults as displayed on the Command & Control Center,
with a brief explanation of each.
The control valve feedback is invalid, indicating the system is not under
control. The valve indicated in the frequency window may be shorted.
The control valve feedback is invalid, indicating the system is not under
control. The valve coil indicated in the frequency window may be open.
Overcurrent condition. The line in which the overcurrent condition exists is
indicated by the location of the string: If in the “Amps Line 1” field, the
overcurrent is in line 1; If in the “Amps Line 2” field, the overcurrent is in line
2.
Voltage Sensor Fault. The indicated voltage may be incorrect, or not under
control.
The voltage lines are perceived to need re-calibration
Oil pressure too high (PSI rating dependent on kW rating)
Pressure transducer signal is out of normal operating range and requires
service/replacement. May cause generator to not operate.
Generator output frequency not able to be controlled high enough. Pump
adjustment or cleaning likely needed.
Reservoir oil level low. Add oil through filler cap to clear. Check for oil leaks.
Oil temperature is getting too high (>185° F). Measured Temperature in the
“Hours” field
Oil Temperature is too high (>195° F).
Oil Temperature dangerous (>220° F).
Indicator Light Ground Fault. The indicator light may not function properly.
Temperature Sensor Fault. The indicated oil temperature may be incorrect.
Buzzer Ground Fault. The audible alert buzzer may not function properly.
The Command & Control Center may not operate properly.
The Command & Control Center is not receiving proper communications and
may not operate properly.
Service Warning: Change oil
Fan Short. The Fan may not operate properly.
Fan perceived to be disconnected and may not operate properly.
VDC to the ECU below validated operational limits. Potential for undesired
results or damage exists.
VDC to the ECU above validated operational limits. Potential for undesired
results or damage exists.
Table 2
Note: The fault “Classes” are defined in the table below:
A condition requires the immediate attention of the operator
A condition causes the immediate shutdown of the generator
A condition that will cause the generator to shut down in 30 minutes
unless explicitly overridden by the operator
