CEM3 User Manual

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.

Control:

Determines the control mode of the dimmer. Possible settings are
Dimmable, Smoothing, Off, Always-On, Switched, Latch Lock,
TPAuto, and TPDMX (see individual definitions below).

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.

Off - Circuit ignores incoming levels and will not turn on even with
local overrides.

Always-On - Circuit ignores incoming levels and will not turn off 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.

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, page 12

TPAuto - For ThruPower modules. The control input to the circuit
dims the circuit if it is between 0 and 99%. When the output is set to
100%, the relay of the ThruPower module closes.
TPDMX - For ThruPower modules. Two addresses (or three
addresses when combined with 16-bit mode) control the dimmer and
the relay of the ThruPower module. When the second address is
below 50%, the first address acts as a relay control, turning the relay
on at the threshold value. When the second address is above 50%,
the first address acts as a dimmer in the normal manner, dimming the
output.

Curve:

The current operating curve for the dimmer. Options are: Mod-
Square, Square, Linear, Mod-Linear, Sensor 2.0, and Custom 1-5.
For more information curves see

Dimmer Curves, page 23

Threshold%:

In switched mode the threshold value defines the control
percentage at which the output turns on. In dimmed mode, the
threshold defines the level at which preheat is applied. See

Dimmer Output Diagram, page 30

for an illustration of how

threshold works with other dimmer properties.

On-Level%:

Latch-Lock only - The control level range (as percentage) that
causes the “On Time” to start counting down. Ranges available in
10% increments. Default is 41-50%.

See

Latch-Lock, page 12

Off-Level%:

Latch-Lock only - The control level range (as percentage) that
causes the “Off Time” to start counting down. Ranges available in
10% increments. Default is 81-90%.

See

Latch-Lock, page 12

On Time (sec):

Latch-Lock only - The time that a level must be maintained before
a circuit is switched on.

Available range is 1-360 seconds. Default is 5

seconds. See

Latch-Lock, page 12

Off Time (sec):

Latch-Lock only - The time that a level must be maintained before
a circuit is switched off.

Available range is 1-360 seconds. Default is 5

seconds.See

Latch-Lock, page 12
