1.3 Diagnostics
General
Over extended periods theremay besmall losses ofpressure inthe liquidcooling systemofthe projector. It isthere for recommended
to check the pressure at regular intervals. In case the pressure drops below 0,5 bar it is recommended to restore the pressure of
the liquid cooling system.
CAUTION: In case of a rapid loss in pressure check the liquid cooling circuit for leakage. Solve the problem
before starting up the projector.
Troubleshooting cooling loop
Any significant or rapid drop in pressure indicates a leakage of liquid. If this be the case, verify w hether the circuit shows any
visible s ign of liquid leakage.
As critical components rely on this liquid cooling, it is essential that any leakage is detected timely.
Periodic checking of the liquid cooling pressure is essential to guarantee overall good performance of the projector and the
pump.
The factory pressure preset is a pproximately 1 bar in the ’Projector Off’ status at a room te mpera ture of 25 °C. This may drop
slightly during operation.
