Crystal Vision
Maintenance
Replacing the dual fan front panel (fitted from November 2010)
•
If possible disconnect the power cord
•
Open the front panel - the display on an active panel will indicate 'Front open'
•
If the frame is powered, the fan on the front panel will stop and the PSU fan will
automatically speed up to maximum speed
•
Disconnect the faulty fan from the fan mux PCB
•
Using a screwdriver, remove the four screws that hold the fan and fan’s finger
guard on a mounting plate which is on the front panel
•
Remove the fan by pulling away from the panel. For the fan furthermost from the
PCB it will be necessary to remove the finger guard from the other fan to release
the wiring
•
Replace the fan with a Crystal Vision supplied replacement part to ensure
adequate cooling and continued fire protection. Ensure the fan is fitted with its air
flow direction and orientation the same as the removed fan – be sure to fit the
finger guards on the outer side of the fan and that the wiring is between the fan
body and finger guard
•
Reconnect the three-way connector to the fan mux PCB connector
•
Close the front panel and reconnect the power supply cord
The front panel fan should be operating and the FRONT FAN LED should be lit green.
The display on an active panel will indicate 'Fault cleared'.
