Crestron electronic CLS-EXP-DIMU User Manual

CLS-EXP-DIMU

Functional Summary

The CLS-EXP-DIMU enables the expansion of the
Crestron iLux™ Integrated Lighting System (CLS-C6
series) and other Crestron lighting dimmers to allow
dimming of both forward and reverse phase type loads.
Supported loads include electronic low-voltage, magnetic
low-voltage, incandescent, neon/cold cathode, or 2-wire
dimmable fluorescent. A single model supports 120, 230,
or 277 Volt loads up to 16 Amps.

The CLS-EXP-DIMU simplifies installation by auto­detecting the dimmable load type connected to it and
selecting the appropriate dimming mode to control that
load. Reverse phase (trailing edge) dimming supports
incandescent and electronic low-voltage load types, while
forward phase (leading edge) dimming handles magnetic
low-voltage, neon, and other inductive load types.

Any output channel of the iLux system can be used to
control the CLS-EXP-DIMU to dim a fully loaded circuit.
It is also compatible with CLW-Series
and select CLX-Series lighting control modules. The
metal enclosure is designed for mounting to a vertical
surface and can be installed in a space used for
environmental air as defined in NEC Article 30 0.22(C).
Conduit knockouts are provided on the bottom and lower
sides. All connections are made via screw terminals
behind the front cover.

• Works with Crestron iLux (CLS-C6 series),

DIN-1DIMU4, CLW1 Series, and CLX Series
dimmers

• Emulates the characteristics of the dimmer that is

controlling it

• Up to five Expansion Modules can be connected

to a single dimmer output

• Supports 120, 230, and 277 Volt ELV, MLV,

NCC, incandescent, and 2-wire dimmable
fluorescent loads

• Auto-selects for forward or reverse phase

• Can be installed in an air-handling space2

• Includes threshold adjustment for setting

minimum fluorescent dimming level

• Built-in air gap relay at the output

• Surface mount design

1. CLW-Series devices must have a dedicated neutral.

2. As defined in NEC Article 300.22(C).

Industry Compliance

This product is Listed to applicable UL Standards and requirements by Underwriters Laboratories Inc. These devices have
been additionally evaluated to UL 2043, The Standard for Fire Test for Heat and Visible Smoke Release for Discrete
Products and Their Accessories Installed in Air-Handling Spaces.

(E103692)

As of the date of manufacture, the CLS-EXP-DIMU has been tested and found to comply with specifications for CE marking.

NOTE: This device complies with part 15 of the FCC rules. Operation is subject to the following two conditions: (1) this
device may not cause harmful interference and (2) this device must accept any interference received, including interference
that may cause undesired operation.

This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to part 15 of the
FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential
installation. This equipment generates, uses and can radiate radio frequency energy and if not installed and used in
accordance with the instructions, may cause harmful interference to radio comm unications. However, there is no guarantee
that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or
television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the
