Leviton Phase Dimmer to GR2404 iDim Hook UP.

Overview

The GR 2404 iDim is designed to outputa 0-10 volt signal for control of FlorescentLights with 0-10volt input Ballasts suchas the Advance Mark 7 ballast.

GR 2404 iDim

Occasionally projects also require Incan-descent or phase controlled ballasts tobe part of the system. In these applica-tions an additional phase control dim-ming section provided by Leviton is used.

Leviton DDS 600 Four channel dimmer

In this case the 0-10 Volt signal from theGR 2404 iDim is used to control thephase angle of the Leviton dimmers.

The lower end of the Leviton Dimmer hasthe inputs for both Multiplexed and Ana-log (0-10Volt) inputs. A 5 pin din cable isprovided pre terminated to theDepluggable terminal strip that outputsthe 0-10 Volts of the GR 2404 i Dim. Ifthe cable is too long it may be shortenedbut make sure that the color code usedby the factory is followed precisely.

For the purpose of documentation thechannel connections are shown below:

Should the cable be lost it can bereplaced by purchasing a MIDI cablefrom a Musical Instruments shop.

If the cable is too long and needs to beshortened then please observer the fol-lowing cautions shown on the next page.

Preparing the cable.

The wires in a Midi Cable which we areusing are 28 gage. This is very thin. TheBraid is the common wire in this examplebut in the one shipped with your projectthe color code MAY be different. Thephotos below are just a typical example.

Note that thethin wireshave beenstripped backby about 1 1/2inches andtightly twisted.The overallcable jacketthat was

stripped back is being used as an insula-tor for the braided wire which has alsobeen tightly twisted.

The next step is to foldover the twisted endstwice. This bulks up thewires sufficiently for thecage clamp connector tomake a good connectiononto the wire.

Now insert the wires in the correct order.Clamping a bit of the insulation insidethe connector is OK and acts as a strainrelief.

Panel Mounting:

Panels are usually mounted in an electri-cal room bolted onto a back board.

This system, shown only partially assem-bled, has two 4 dimmer units with a 16relay panel above. The Din plug isplugged into the jack at the bottom of thedimmer:

Since each line is feeding 2 dimmer therelays need to be in series AFTER thedimmers.

Dip Switch Settings

The DIP switch inside the panel shouldbe preset at the factory for dimming out-puts. Please verify that the settings arecorrect.

The DIP Switch inside the panel is theonly one that applies in the Analog mode.The one on the exterior end of the panelis not used in the analog mode.

The default settings are shown in yellow.These are what should have been set atthe factory.

By “Channel acts as Relay” is meant thatthe channel is a “Non-Dim” and will eitherbe ON or OFF.” Transition level is at1.5Volts.

Auto Sequence Mode.See the Leviton DDS 6000 User Guidefor instructions on using the AutoSequencing mode. #8 on the exterior Dipswitch must be set to ON to allow properfunctioning.

ProgrammingAll programming is done via the GR 2400system.

The Leviton DDS 6000 is off at 0 Voltsand starts dimming up from there to fullon at 10 Volts.

This is different from standard Florescentdimmers which output minimum dim from0 Volts to about 1.5/1.6 volts. They startfading up from there and reach maximumintensity at about 8 volts and stay thesame from 8 to 10 volts. Different brandshave different curves.

If Florescent dimmers and incandescentdimmers are being mixed set the trim onthe Florescent channels to ensure that allthe loads dim with the same curves.

Appendix

Dimming 277Volt Ballast Loads. TheAdvance Mark 10 Ballast requires aphase dim control. These ballasts areavailable in 277Volt versions. In suchapplications a Leviton PE200-7 Powerextender must also be ordered along withthe dimming system since the DS 6000 isonly available in 120 Volt.

The wiring for this more carefullydescribed in the hook up sheet shippedwith the unit. A diagram is shown belowfor overview purposes. Note that aPE200-7 is needed for each channelcontrolled.
