Damaged wire insulation of the temperature sensor which measures the ambient temperature of the Light Processor compartment. When disconnecting the wire of the temperature sensor from the Signal Backplane (reference 5 image) the error code is changed to “... is not connected”.

1. Repair the insulation of the of the temperature sensor which measures the ambient temperature of the Light Processor compartment (reference 1 image).

2. If not repairable, replace the temperature sensor and wires.
