T917_O: PIM Temp High
This fault is very similar to the T908_O PIM Overtemp
On the VSODU, this fault would be displayed on the seven-segment LED as a number 15. A 15 displayed is one of several inverter faults. You will need to validate this fault at the EcoNet Thermostat or by looking at the red or yellow flashing LED's in the upper right quadrant of the drive itself
The Drive LED's will be flashing the yellow LED either 4 or 18 times.
The fault is triggered because the PIM or "Power Inverter Module" is temperature reaches a threshold temperature. This can be from something as simple as a inoperable condenser fan motor, a dirty outdoor coil, or a dirty heat sink on the back of the drive, on an extremely hot day. Ensure nobody has tried to separate the drive from the heat sink.
If the fan has failed, resolve that. If the outdoor coil or heat sink is dirty, clean it.
