the temperature reaches the TOP limit, the heater may be enabled and the fan
disabled, which is why the mode should only be used for Test and Service use.
If the DEC3 has been purchased with DMX/RDM enabled, it is possible to select the required mode
1-3 using RDM. In the RDM context, this is known as selecting the device’s DMX PERSONALITY.
Setup of the DEC3 from the Front Panel is available in all configurations.
RDM is an effective and powerful tool for commissioning and monitoring an installation,
particularly in large systems. For further guidance, we recommend you consult a
qualified RDM system integrator. If you don’t have one in your neighborhood, go to
www.tempestlighting.com , and click on the RDM and RDM Integration bug on the home
page for some useful contacts. Tempest Lighting warrants DEC3 to be compliant with
the RDM standard, but is not an RDM systems integrator, and can offer only basic guidance on
RDM utilization.
DEC3 Control Parameters
DEC3 will run out of the box with its default parameter settings, which equate to the (fixed)
settings of its predecessor DECs 1 and 2.
Temperature:
Top Set Range 35-45°C, Default = 40°C
Most manufacturers recommend a max temperature for their
equipment of 40°C, though this does vary. When DEC3 senses a
temperature higher than Top Set, it indicates an overtemp
condition as a warning. NOTE: in moving light enclosures the
thermal sensor is necessarily placed in the exhaust air path,
which will be higher (sometimes a lot higher) than the actual
fixture ambient. This needs to be kept in mind when adjusting
temperature settings.
Cutoff Temp Range 0-15°C, Default = 15°C
This is a setting above the Top Set temperature that determines
the temperature at which the lamp relay is opened, cutting off
power from the fixture/projector. The user may reduce it as
desired, but should establish before doing so the actual
operating temperatures experienced in hot weather before doing
so, to avoid nuisance tripping.
Bottom Set Range 0-10°C, Default = 10°C
The temperature maintained by the heater in cold conditions.
Most equipment manufacturers recommend a minimum
operating temperature of 0°C, and users may set it lower than the
default if desired.
Humidity Range 50-90%, Default 80%
