LED Indicators
Heater
SHORT PULSES (Green) – Indicates lamp is off, and the heater is pulsing to prevent
condensation inside the enclosure and projector/light fixture. This is normal operation
when the lamp is off and the temperature range is above the bottom set limit. Timing
intervals may vary – this is normal.
ON (Green) – Indicates heater is on, due to temperature being below bottom temperature
setting when lamp is off.
OFF – indicates lamp is on and maintaining temperature above bottom limit.
Fan
SHORT PULSE (Green) – The fan is moving a little air through the enclosure, as part of the
condensation prevention strategy. The fan comes on for a few seconds approximately
every 30 seconds.
ON (Green) – Fan is running, due to lamp being on or internal temperature exceeding top
limit.
Lamp On
ON (Green) Indicates current sensed on the lamp circuit greater than 0.5 amp (this allows
some current to be drawn for such things as fans and control electronics without the
Lamp On indicator lighting. When the Lamp On indicator is on, the lamp counter is
counting lamp life.
Lamp Relay
ON (Green) – Indicates lamp relay closed and power is available to the internal fixture.
OFF Indicates lamp relay open and power is removed from the internal fixture.
Temp
ON (Green) – The temperature is between Bottom and Top temperature settings.
ON (Red) – The temperature is either:
a) Below Bottom Setting
b) Above Top setting but below the Cutoff level.
FLASHING (Red) – Temperature is above Cutoff level or below Bottom level.
