3. Troubleshooting
Situation
Solution
Interruption of the liquid cooling
circuit.
Check if the loop of the liquid cooling circuit is closed.
The liquid cooling circuit of the light
processor is mistakenly excluded
from the main liquid cooling circuit.
Reconnect the cooling circuit of the light processor with the pump and heat exchanger.
Water cooling pump electrical
disconnected.
Check if the wire unit (ref C image 3-13) of the pump is properly connected.
Blocked high density filter of the
heat exchanger.
Replace the blocked high density filter with a new one.
No or insufficient liquid inside the
cooling circuit. The pump is sucking
air and sounds noisier then normal.
Fill the cooling circuit with liquid and expel all air. Pressurize the circuit. See "FLM
liquid cooling circuit", page 153.
Malfunction pump of the water
cooling circuit. You don’t feel any
vibrations when touching the pump
after activating the “Refill mode” via
the user interface:
Service > Refill mode >
Yes
Note: to exit the “Refill mode” you
have to switch off the projector.
•
Check the electrical resistance of the pump’s winding. Replace the pump if infinite.
See "Cooling pump replacement", page 197.
•
Drain the liquid cooling circuit, open the pump and check if the pump is not blocked.
If so, remove the rotor (ref R image 3-13) and clean the bearings of the pump. See
"Maintaining the cooling pump", page 190.
