DMX level 81-100 No change to relay status
SET DATA RESPONSE
DMX Response sets a delay time before DMX Control Mode settings are acted on. Setting a response delay of a few
seconds would prevent unintended fixture relay state changes in the event of a short accidental change in DMX
level.
NOTE: from firmware revision 0.00.100, DEC holds last valid DMX level if DMX is interrupted.
Response Delay Values are:
No Delay (default), 1, 2, 5, 10, 15, 20, 30, 60 seconds.
Set Temp Units
Choose to display temperature values in Celsius or Fahrenheit (default Celsius)
Note that temperature settings must be entered in Celsius.
Set Temp Ranges
Set three temperature trigger points for Bottom, Top and Trip temperatures, in °C.
SET TEMP LOWER (minimum temperature to be maintained)
(default 0°C, permissible range 0-10°C).
SET TEMP UPPER (maximum desired daytime temperature)
(default 45°C, permissible range 35-50°C).
SET TEMP TRIP (temperature at which load will be isolated – see note)
(default 60°C, permissible range 55-70°C).
Note: A thermal emergency is when enclosure ventilation fails with the lamp on, in which case the temperature will
rise very quickly. To avoid nuisance tripping we recommend setting a higher Trip temperature, 60°C or above.
Set Max Humidity
Sets highest desired Relative Humidity: Default 85%, permissible range 80-90%.
Note that, when the projector/luminaire lamp is OFF, the enclosure heaters will switch on to raise the temperature
and lower the risk of condensation. We recommend setting the highest Max Humidity that works in your location, to
avoid unnecessary heater use.
Set Lamp On Point
The lamp current at which DEC detects the projector/luminaire lamp is running. Default is 1 Amp, which allows for
most equipment fans and power supplies to run without changing the air in the enclosure. Lamp on point may be
set in 0.1 Amp increments between 0.2 Amps and 2.0 Amps.
If the enclosure fans never turn off, the Lamp On point is probably set below the standby current draw of the
projector/luminaire. Check the current draw on the display, and set the Lamp on current higher.
