a)
Humidity – relative humidity in %
b)
Firmware version
c)
Lamp Hours elapsed
d)
Current being drawn by projector/light fixture, in amps
e)
PCB temperature
f)
Air temperature, in degrees C or F (note that sensor is placed in the exhaust
airflow in Tornado enclosures and may be higher than the temperature being
‘seen’ by the fixture body or electronics)
RESET LAMP HOURS
The lamp hour counter needs to be reset each time you change the lamp in the
fixture/projector. Make this a part of your maintenance instructions.
HUMIDITY SET
The humidity level above which the heater kicks in to remove humidity from
incoming air (default 80%, permissible range 50-90%).
SET FAN OVERRUN
The fan will continue to run for a time after the internal fixture has gone to standby. This
facility allows the heat built up in the fixture to dissipate before the DEC3.2 resumes
normal maintenance of the enclosure.
(default 5 minutes, permissible range 0-15 minutes)
SET TEMP RANGES
Set three temperature trigger points for Bottom, Top and Cutoff temperatures.
TEMP BOTTOM
The desired lower temperature limit for normal operation
(default 10°C, permissible range 0-10°C).
TEMP TOP
The desired upper temperature limit for normal operation
(default 40°C, permissible range 35-45°C).
When the DEC3.2 sees air above this temperature, but below the additional Cutoff
temperature (see below), it indicates a temperature error. This is not dangerous.
TEMP CUTOFF
The desired upper temperature ABOVE the TOP TEMP setting, at which the lamp relay is
forced to open, isolating the fixture/projector power.
(default 15°C, permissible range 0-15°C).
To avoid nuisance tripping, set this variable to the maximum, and monitor actual
temperatures in your normal operating conditions. If your actual temperatures are
