NOTE: When wiring the GL-EXP-DIMFLV-CN, the 0-10V control wires from the + and –
terminals can be wired as Class 1 or Class 2. The unit ships with a barrier to the right of
the 0-10V terminal block for Class 1 wiring. If using Class 2 wiring, move this barrier to
the left of the 0-10V terminal block.

3. Replace the cover and cover screws.
4. Apply power to the module. The power indicator LED lights indicating that power is
supplied to the module.
Dimming Mode (GL-EXP-DIMU-CN Only)
The GL-EXP-DIMU-CN uses Autodetect mode to determine the attached load type and
applies Forward Phase (leading edge) or Reverse Phase (trailing edge) dimming mode.
Autodetect mode can be overridden to force a dimming mode. Disabling 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.
WARNING: Incorrectly setting these switches to force the wrong mode can cause
damage to the dimmer and lighting xture.
The dimming mode can be changed by adjusting the SW3 and SW4 DIP switches as
detailed below.
SW3 SW4 DIMMING MODE LOAD TYPES
OFF OFF Autodetect
(default, recommended)
All
ON OFF Forward-phase Magnetic low-voltage, neon/cold
cathode, 2-wire dimmable uorescent
OFF ON Reverse phase Incandescent, electronic low-voltage
Zero-Cross Mode
Zero-cross mode is available for the GL-EXP-DIM-CN, GL-EXP-DIMFDB-CN, and
GL-EXP-DIMU-CN only.
The GL-EXP-DIM-CN, GL-EXP-DIMFDB-CN, and GL-EXP-DIMU-CN ship with SW1 set
to OFF. The dimmers should generally be left in this state. If unusual line conditions are
occurring (for example, a 3-1 ash pattern described in “Error States”) contact Crestron
Technical Support. Crestron Technical Support may recommend setting this switch to ON
for Filtered Zero-cross mode.
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 Zero-cross mode is set using the SW1 DIP switch. Refer to the following table when
setting the Zero-cross mode.

Error States
The ERR LED ashes a specic pattern to indicate an error. The ash patterns are
described in the table below as, for example, 1-1 or 2-1. A 1-2 ash pattern means that
the LED ashes one time, pauses for one second, ashes two times, pauses for ve
seconds, and then repeats until the error is corrected.

1-1 The slave processor is in bootloader.
1-2 The slave processor is unresponsive.
1-3 The slave processor rmware update failed.
2-1 There is an over-current error.
2-2 A FET is shorted.
2-3 An over-temperature error exists.
2-4 An over-voltage error exists.
3-1 A zero-cross sync error exists.
