3. Apply power to the line/load and turn on the
controlling device. The power indicator LED will
light indicating that power is supplied to the
module.
4. Replace the cover and cover screws.
Dimming Mode
The CLS-EXP-DIMU is capable of automatically
detecting the attached load type, and setting itself for
forward-phase (leading edge) or reverse-phase (trailing
edge) dimming accordingly. In addition, the unit can be
forced to perform forward- or reverse-phase dimming by
overriding the automatic detection.
Disabling the Auto Detect mode should not be
necessary, and is not recommended unless suggested
by a Crestron technical support representative.
WARNING: RISK OF SERIOUS PERSONAL
INJURY. Turn off power at the circuit breaker(s) prior to
changing any switch settings. Changing settings with
power on can result in serious personal injury and damage
to the device.
The dimming mode can be changed by adjusting the S1
DIP switches as detailed in the following table.

Zero Cross Detection Filter
The CLS-EXP-DIMU performs filtering to compensate
for noise on the incoming AC line. This filtering is useful
for eliminating flickering of the load caused by line noise.
If necessary, this filtering can be disabled.
Disabling the zero cross detection filter should not be
necessary, and is not recommended unless suggested
by a Crestron technical support representative.
WARNING: RISK OF SERIOUS PERSONAL
INJURY. Turn off power at the circuit breaker(s) prior to
changing any switch settings. Changing settings with
power on can result in serious personal injury and damage
to the device.
The function of the zero cross detection filter is set using
the S2 DIP switch. Refer to the following table when
setting the zero cross detection filter.

SW. 1 SW. 2 DESCRIPTION
Off Off Enable zero cross detection filter
(Default, recommended). Provides
maximum filtering under various line
noise conditions.
On Off Disable zero cross detection filter.
Allows rapid tracking of the AC line.
Suitable when using generators for AC
line power.
Set the Minimum Dimming Level
Certain types of loads can flicker when dimmed too low.
Adjust the FLUORESCENT OFF THRESHOLD to
prevent the CLS-EXP-DIMU from attempting to dim the
load below a certain level. To adjust:
1. Remove the cap from the FLUORESCENT OFF
THRESHOLD adjustment from the inside of the
cover (requires removal of cover as shown on
previous page).
