Troubleshooting
Projector does not have power:
1.
Check Projector power switch
2.
Check projector is plugged into DEC4 projector outlet
3.
Check that enclosure feed circuit is on
4.
Check DEC4 User Interface leds are on. If feed circuit is on and UI leds
are off, check feed wiring to DEC terminals and meter DEC4 projector
outlet for power
5.
If UI lamp led is on and DEC4 projector outlet is live, there is a projector
fault.
Enclosure overheats:
1.
Is the projector connected to the DEC4 projector receptacle? If the
projector is powered independently the controller has no way to know
when to turn on the exhaust fans!
2.
Is the filter clogged or obstructed?
3.
Check that the Fan led on the UI is on when the projector is running. If
not, then the projector is probably not connected to the DEC (see 1).
4.
If the fan led is on, check that the fan is running. If not, check fan
wiring. If wiring is ok, fan may be faulty.
5.
Check the UI display for RH (relative humidity) message. If display reads
RH 5%, RH 100%, or RH###, there is a sensor fault. Contact Tempest for
a replacement sensor.
Dirt/Debris inside enclosure
1.
Filter is either missing or damaged?
2.
Filter is not properly seated
3.
Side panels or back door is not firmly latched
Water in enclosure
1.
Check the drain holes in the bottom of the enclosure. If they become
blocked, and water that gets in cannot escape.
2.
Check seals around side panels and back door
Fan LED is on but fans do not operate
The exhaust fan is protected by a 20mm 4A slow-blow fuse on the DEC4
motherboard, and a secondary fuse on the fan board. In very exceptional
cases it is possible that either fuse could fail. Check visually.
The fuse is protected with a clear resin sealant and soldered to the circuit
board. With care, you can de-solder the fuse and replace it, but we
recommend replacing the DEC4 motherboard to maintain the integrity of
the board’s conformal coating.
Heater LED is on but heater does not operate
The heater is protected by a 20mm 10A slow-blow fuse on the DEC4
motherboard. In very exceptional cases it is possible that it could fail. Check
visually.
The fuse is protected with a clear resin sealant and soldered to the circuit
board. With care, you can de-solder the fuse and replace it, but we
recommend replacing the DEC4 motherboard to maintain the integrity of
the board’s conformal coating.
None of the above?
