The liquid cooling circuit of the Light Processor is mistakenly excluded from the main liquid cooling circuit. Most likely the DMD temperatures are too high as well.

1. Check if the DMD cooling circuit is correctly connected with the DMD cooling expansion module of the chiller.

2. Check if the cooling circuit inside the Light Processor compartment is correctly connected.

3. In case of a 45L or 60L projector model, check if the small Airdryer is included in the cooling circuit.

Malfunction small Airdryer. The DMD temperatures are too high as well (only for 45L or 60L projector model)

Check for warnings and errors related to the small Airdryer and resolve these first.

Malfunction Heat Exchanger. The DMD temperatures are too high as well (only for 22L or 30L projector model)

1. Check if the Heat Exchanger inside the Light Processor compartment is not blocked.

2. Check for errors related to the Heat Exchanger (e.g. fan) and resolve these first.

Defect temperature sensor. When disconnecting the wire unit of the temperature sensor from the Signal Backplane (reference 5 image) the error code is changed to “... is not connected”.

Replace the temperature sensor (reference 1 image).
