5. Troubleshooting
Most of the APC operating problems may be detected thanks to the controller.
Refer to the troubleshooting paragraph of the controller instruction manual.
If the controller is connected but doesn’t display anything, check the voltage presence to its leads.
If there is no voltage, this may be explained by:
a discontinuity of the circuit (check the wiring, fuses, etc…)
an overtemperature of 60°C having caused the opening of the temperature probe and thus the power
supply cut off. This overtemperature may be due to an ambient temperature upper to the maximum
allowed temperature.
a ventilation system as well as a defective temperature probe causing the RVC power supply cut off at
85°C.
a defective temperature probe opening without overtemperature.
