PSU fan showing three-pin connector and finger guard
Replacing the front panel fan
To replace the front panel fan proceed as follows:
•
If possible disconnect the power cord
•
Open the front panel - the display on an active control 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
•
Undo the three-way connector – which is attached to three wires on the fan – from the
front panel PCB labelled PL6
•
Using a screwdriver, slacken the four plastic screws that hold the fan and fan’s finger
guard on a mounting plate which is on the front panel
•
Remove the fan and finger guard completely
•
Replace the fan with a Crystal Vision supplied replacement part to ensure adequate
cooling and continued fire protection – be sure to fit the finger guards on the outer side
of the fan
•
Reconnect the three-way connector – which is attached to three wires on the fan –
into the front panel PCB connector labelled PL6
•
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'.
