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%
