•The column LED should light.
4Reinstall the blower unit and tighten the retaining screws.
•The column LED should go out.
•The system terminal should display PWR0046.
5Heat one of the two thermal sensors under the top cap of the column with a
•The column LED should light.
•Thirty seconds after the thermal sensor detects 70 degrees C
(158 degrees F), the main circuit breaker, or the blower unit circuit breaker, at the rear of the pedestal should trip. The system terminal should display PWR0004, PWR0006, and PWR0007.
6Allow the sensor to cool, then reset the circuit breaker in the pedestal. If a sysload occurs, allow it to complete.
•The column LED should go out.
•The system terminal should display PWR0044, PWR0046, and PWR0047.
7Repeat step 5 and step 6 for the other thermal sensor.
