Control System Crestron Lighting
Step 2: Module Selection
The enclosure mounted Crestron modules, connected to the appropriate terminal
block, perform pre-determined functions with various types of light sources, motors
and non-lighting loads. Modules have a Cresnet link for control processor
communication and a module override connection. Six different modules are
available. The type of load, number of circuits, required current load capacity, and
economic considerations are all determining factors when choosing modules. The
number and type of modules is determined from the load schedule. The number of
required modules will determine the size and type of enclosure(s) in the next step.
Each module is wired via the terminal block to a circuit breaker (provided by others).
The power provided to the module is distributed to all of its outputs. Each module
contains relays that provide an individual air gap for each controlled high voltage
circuit. Module selection can be done manually or by the D3 Pro software.
NOTE: A module terminal block (CLT-Series device) must also be ordered for each
module. The corresponding CLT terminal block is installed in the enclosure for high
voltage wire termination. Each terminal block includes a terminal rail for mounting
the terminal block in the enclosure. Terminal rails and blocks do not occupy a
module space within an enclosure.
Oversized heat-sink fins on the face of the module provide superior heat dissipation,
eliminating heat related failures. The modules incorporate spit-bobbin transformers
and ground reference electronics for superior performance. AC line noise
interference and lamp flicker are eliminated by an innovative zero-crossing detection
technique and unique Crestron firmware. The red LEDs on the side of the module
indicate the presence of voltage to the module output. The brightness of the LED
corresponds to brightness of the lights. The green and amber Cresnet
communications LEDs indicate both power and communication.
