Tornado G4 User Manual
1. Check Luminaire power switch
2. Check luminaire is plugged into DEC4 luminaire
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 luminaire
outlet for power
5. If UI lamp led is on and DEC4 luminaire outlet is
live, there is a luminaire fault.
1. Is the luminaire connected to the DEC4 luminaire
receptacle? If the luminaire 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
luminaire is running. If not, then the luminaire 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.
1. Filter is either missing or damaged?
2. Filter is not properly seated
3. Side panels or back door is not firmly latched
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 the globe and globe collar
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.
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
