Trouble Shooting - GRE VSG75 Instruction Manual

8. TROUBLE SHOOTING:

Computer Controlled Trouble Shooting Features for VSG75 Pumps:
1. High or Low Temperature Protection
When the motor temperature is higher than 90ºC or is lower than -5ºC, The pump will stop and the error code
TP is displayed. When normal motor temperature is restored, between 5ºC to 60ºC, The pump will start auto-
matically according to user's automatic mode programming.
2. Blocking or Jamming Protection
When the motor impeller or the motor is stuck, the error code BP is displayed. The pump will automatically
attempt to restart in 6 seconds. If restarting does not happen automatically after several attempts users need
to check the impeller and motor. Always turn off power before attempting maintenance.
3. Voltage Overload Protection
When the controller has a fault such as over load or over current, the error code OL is displayed. The pump tries
to restart in 6 seconds automatically if the pump is not damaged.
4. Phase-Loss Protection
When the main PCB detects a phase loss problem (e.g.the motor cable is not properly connected), the error
code LP is displayed. The pump will try to restart automatically in 6 seconds after the cable is reconnected or
the phase loss is resolved.
5. Communication Loss Protection
When a communication failure occurs between the display PCB and the main PCB inside the pump, the error
code CP is displayed and pump stops.
