2	Universal Source Controller - Feed Through

Introduction

Welcome

The iLumin Universal Source Controller range from Eaton’s Cooper Controls Business has been designed to provide maximum flexibility in both installation and operation. Every model in the range can accept a variety of industry standard control options, from iCANbus to DMX, from ethernet to RS-485. Similarly, every model can drive a wide range of lighting loads, from incandescents to dimmable fluorescents, from non-dim apparatus to DALI digital modules.

Much care and attention has been applied to the installation and maintenance of the Universal Source Controllers.

Each model provides clear, logical cable routing and every high voltage channel is controlled by an individual, easy to replace dimmer card.

Specifications

The numerous models within the Universal Source Controller range share the following key specifications. Information specific to each cabinet model are provided elsewhere throughout this guide.

●●All channels provide switched (non-dim) and dimmed high voltage load control as standard

●●Leading-edge triac dimmer engines capable of withstanding repetitive inrush currents of 50 times operating current without impacting lifetime

●●All dimming and switching circuitry for every channel located on individual boards for quick and easy swap-out, if necessary

●●Voltage and frequency compensation to maintain light level during supply fluctuations

●●Power monitoring for each circuit and the total panel

●●Bypass jumpering fitted as standard to protect circuits and allow work lighting during installation

●●Selectable low voltage load control available per channel for dimmable ballast control

●●Low maintenance and quiet operation thanks to fanless, convection cooled operation

●●Support for multiple control protocols: iCAN for links to multiple control sources; DMX512A for links with entertainment systems; RS-485 for integration with building management schemes and ethernet for connection to a variety of systems

●●Dual volt-free switch inputs, with programmable responses, for integration with emergency control devices, building management systems, etc

●●Compact wall mounted design with easy access to all internal items and lockable front panel door for added security

●●Intuitive control panel provides straightforward programming and configuration of the system. The control panel allows a base level installation to be configured without the use of separate PC programming

Safety

Please Read This First

The Universal Source Controllers are designed, built and tested to strict safety regulations. By following the steps listed below and elsewhere within this guide, you can ensure safe installation and operation of these controller units.

●●The Universal Source Controllers must be installed only by a qualified electrician

●●The installation must comply with the appropriate electrical codes and regulations in force in your area

●●The Universal Source Controllers are designed for indoor installation and use only. The units can, however, be used to control appropriately certified exterior lighting fixtures

●●Ensure that all wiring used conforms fully to local specifications and is sufficiently rated for the installation

●●All new wiring must be fully verified before applying power

●●The high voltage supply should be fed to the Universal Source Controller via an external isolation breaker with sufficient capacity for the planned installation

●●All Universal Source Controllers exceed the weight limit for one person lifting - always use at least two people when lifting and mounting the units

●●Do not mix load types within a single channel (e.g. 120V tungsten and low voltage ballast control)

●●Ensure that the supply is fully isolated at an external breaker before removing the chassis covers. Test that power has been removed before starting to handle conductors

●●Ensure that high voltage and low voltage wiring remains separate

●●Each dimmer channel should be protected by its own dedicated external circuit breaker.

Important Points For Consideration

●●The Universal Source Controllers must be mounted flush with the wall, do not recess the controller chassis

●●Upper and lower raceways must not be located within 8 inches (200 mm) of the upper and lower panels of the Universal Source Controller. Use suitable conduits and couplers to link the raceways to the controller chassis

●●Allow adequate space for future maintenance of the unit. Do not install in a location that will later be difficult to access

●●The Universal Source Controllers are designed to be mounted vertically

●●During operation, the Universal Source Controllers will produce audible noise caused by electrical noise suppression circuitry and also the circuit relays within the unit. The noise is a low level buzz that varies with the level of dimming and also clicks when relays are energised. Take these matters into consideration when deciding on a suitable mounting position.

Mounting

●●The hinged cover must be unscrewed and removed from the front cover when the Universal Source Controller operates at full load in a high ambient environment

Ambient Atmosphere Requirements

Temperature	320 F to 1040 F (00 C to +400 C)
Humidity	0 to 95% non-condensing

Mounting

Location and Spacing

The Universal Source Controller models are all fully convection cooled, therefore it is vitally important to ensure that each unit is installed in a ventilated location that permits sufficient airflow and provides the correct ambient conditions.

Ensure that the minimum distances to walls and other equipment shown in the diagrams below are maintained.

Also ensure that the stated ambient atmosphere requirements are not exceeded.

Refer to ‘Important points for consideration’ when choosing a mounting location.
