Dimmer Property Definitions
Each dimmer has specific properties that dictate how the dimmer functions and how CEM3 will control
it. Edit these properties in the Dimmer Setup screen [Setup]>Dimmers.

Definition
Ckt
Circuit Number. A user-assigned number for a unique circuit
within a space. Typically the circuit number matches the labelling
at the corresponding power outlet.
Module
The type of module controlling the circuit. Defines module
density, ratings, and features to ensure proper function of the
connected equipment and power devices in the module.
Control
Set the control mode of the dimmer.
• Off: Circuit ignores incoming levels and will not turn on even
with local overrides.
• Switched: Circuit operates as a relay with output unregulated
AC voltage when the control level is above the control
threshold level.
• Always-On: Circuit ignores incoming levels and will not turn off
even with local overrides.
• Latch-Lock: Similar to switched mode, Latch-Lock functions as
a relay but features an additional safeguard so that circuits can
not be turned on or off so easily. See
Latch-Lock
on
page 7
.
• Dimmable: Circuit dims according to curve within the
minimum and maximum scaled voltages.
• Smoothing: The dimmer adds a deliberately slow reaction time
to changes in control level to “smooth out” dimming
performance with loads that react quickly such as LEDs or low
wattage lamps.
• TPAuto: Allows control of ThruPower behavior using one single
DMX address, where full (DMX value 255) closes the relay and
any other level is dimmed.
• TPDMX: Allows control of ThruPower behavior using two DMX
addresses:
- Configured address, e.g. 105 - Control Address
- Subsequent configured address, e.g. 106 - Mode
Address
When Mode Address is set to a DMX value of 0–127, the
ThruPower Circuit acts as a switched circuit. If the Mode
Address is set to a value of 128 or above, the ThruPower Circuit
acts as a dimmed circuit.
Firing
The firing mode of the dimmer module. Options are: Normal,
Dimmer Double, or Fluorescent. Specific module types will also
offer respectively: Reverse Phase and Thru-Power.
