Ci-Nergy – Controller & inverter fault codes

March 1, 2007


Control fault codes

The following error codes will display on the user interface located on the face of the control panel. To clear a fault follow the on screen instructions. Should a fault continue to display contact Amarinth on 01394 462 120 and ask for Ci-Nergy technical support.

Display / ErrorCauseRemedy
ACTIVE FAULT E-STOP TRIGGERED Emergency stop button pressedRelease the emergency stop button and on turn the controller (start/stop button – S/S)
ACTIVE FAULT INVERTER FAULT Inverter fault.Fault code from inverter will need to be ascertained (see inverter fault codes below).
SENSOR FAULT Pressure sensor failed or outside normal operational range.Replace faulty sensor
HIGH STEAM PRESSUREHigh pressure in vapour space of tank – possible steam trap failed.Check condensate return line / steam traps.
HIGH LEVEL ALARMTank overflowing. High condensate return rate. Inverter tripped out.Check condensate return rate. Fault code from inverter will need to be ascertained (see inverter fault codes below).

Inverter faults codes

The following error codes will display on the inverter screen located inside the control panel. Care must be taken when reading an inverter error code as you will need to open the control panel door, turn off all breakers except for QF2 and turn the unit back on at the mains isolator. Note there are now live circuits in the panel. Navigate to b97 to review the alarm logs. For more information refer to the inverter manual.

DispalyErrorCauseRemedy
OHThe inverter is overheated during stopAmbient temperature too high or poor ventilation. Improve ventilation
OCA/OCSOver-current at acceleration/start-upShort circuit between motor wiring and earth.Check motor wiring
OVCOver voltage during operation/deceleration Power voltage varies widely.Use a reactor on the power input side
OHCHigh heat sink temperature during operation Heavy load. Ambient temperature too high or poor ventilation. Check system loads/throttle pump discharge Improve ventilation Check inverter cooling fan is operation Check the setting value of b87
OL1Motor overloadHeavy load. Improper setting of b09 (motor current). Check system loads/throttle pump discharge Set b09 correctly according to motor nameplate current
OCLOver current limitHeavy load. Continuous over load. Set stall prevention function from b23 to b29
LVCUnder voltage during operation Power voltage too low. Power voltage momentary dip.Improve power quality Use a reactor on the power input side
