3.
Apply power to the line or load and turn on the
controlling device. The power indicator LED
lights, indicating that power is being 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 mode accordingly. In addition, the unit
can be forced to perform forward or reverse phase
dimming by overriding the automatic detection.
Disabling the Autodetect 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 the
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 table in the following
column.

Zero Cross Detection Filter
The CLS-EXP-DIMU filters 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 the
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.

DESCRIPTION
Off
Off
Enables zero cross detection filter
(default, recommended), which
provides maximum filtering under
various line noise conditions
On
Off
Disables zero cross detection filter;
Allows rapid tracking of the ac line;
Suitable when using generators for ac
line power
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.
NOTE
: Some fluorescent ballasts may require that
voltage levels be maintained above a specified minimum
level to prevent premature lamp failure. Be sure to set the
minimum dim level so that the minimum voltage is met at
all times when the load is on. Consult the ballast
manufacturer’s documentation for details.
