Introduction
ThismanualistoaccompanytheMXseriesdimmerrack
by Electronics Diversified Inc. We believe you will find
our equipment reliable and well suited to your purpose.
In the next few pages we will be giving you further
information about the operation and maintenance of the
MX series dimmer rack. As always, our local represen-
tatives will be very pleased to help you. If you need
furtherinformationorassistance,youmaybedirectedto
our factory technical and sales staff. Our Hillsboro fac-
tory number is noted below and at the back of this book.
The MX
This rack is designed to accommodate the MX series
dimmer modules. There are several different modules.
The difference lies primarily in the functional character-
istics of the particular module. You may find it useful to
inspect the rack to determine which type(s) of modules
are being employed.
There are three sizes of two dimmers per module MX
series dimmer rack, the quarter size, the half and the
standard. Operationally they are identical.
Atthetopofeachrackisawindowgivingsomefunctional
information about the rack. Part of this are two LEDs
indicating the status, that is; one which indicates every-
thing is okay, the other means there is some problem
within that particular rack.
Just below this is the Multi Link Intelligent Control
Module.Stacked down from this unit are the dimmer
modules. Note there may be more than one type of
module in your rack.
Behind and to either side of the modules are the electri-
cal connections, the busses. These last are likely to be
electrically charged at high voltage, please exercise
caution.

Removing / hanging the Door
The door is easily removed and re-hung. It may be useful
to remove the door for maintenance or service.
A key is required to operate the cam-style locks.

Angle the door out at the bottom and allow it to drop down
off the top hinge pin.
To replace the door, follow the reverse of the above
procedure.
Notice the top hinge pin is longer than the bottom, the
sequence noted above is the only easy way to hang or
remove the door.

Dimmer and Rack Maintenance
The MX system, like all electrical / electronic equipment
is affected by the presence of dirt and dust. We recom-
mendthe rackbe opened,themodulesremovedandall
items cleaned to remove this dust.
Pleasesfollowthisprocedure:
•ShutdownandDisconnectPower.
•Removethedoor.
•Removeeachdimmermoduleandindividually
clean either by vacuum or low pressure com
pressedair.
•Clean the other interior areas of the rack in the
samemannerastheindividualmodules.
•Inspect the internal connections of the main
feedersandof thebranches tothemodule
plugs.
•Inspectthe connectorends fordiscoloration
indicatinga poorconnection.
•Aftercleaningand inspection,replacethe
modulesandthedoor.
Note: Annualcleaningisrecommended,morefrequently
iftheenvironment is particularlydirty.
To help prevent the build up of dirt, the Electrostatic Air
Filtersmaybecleanedorreplacedfrequently.
To clean the Air filters:
•Removeairfiltersfromdoor.
• Wash with a light to medium pressure water
spray. Use cold to luke-warm water.
• Allow to dry and replace.
Note: Thefilter(s)must be replacedwith the correct
side facing the interior of the cabinet.
Dimmer Module
The standard dimmer modules provide one LED indicator
per dimmer circuit which gives a visual indication of the
dimmer activity. Also provided is another LED indicator
which warns of a fault in that module.

2. Phase B fuse
3. Phase C fuse

1, 2, and 3 are dark. Input power source is off. Check input power source.
A dimmer circuit is always OFF. The dimmer module is not plugged in. Makesure dimmer isfirmly plugged inallthe way.
Checkcontrolwiringconnectortosolidstaterelays.
Defective solid-state relay. Replace the solid-state relay.
Circuit Breaker is off. Turn on circuit breaker.
All of the lamps "ghost" (glow). Dimmer preheat set too high. Reduce preheat level.
Control out of calibration. Contact the factory.

lamps flicker, or dimmers refuse to
respond to dmx signal. Bad DMX cable. Check the dimmer pack with a known good cable.
The dimmer pack overheats. The cooling vents are blocked. Clear any obstructions to the cooling vents.
The dimmer module is full of dust. Carefully remove dust and dirt with compressed
air or a vacuum cleaner.
The dimmer is in a very warm location. Relocate the dimmer to a cooler location.
Dimmer Removal / Installation
To remove a dimmer from an MX rack please follow this
procedure:
•Be certain of the position of the Dimmer Module to be
removed. Locate this Module by using the Circuit
numbering label located to the left of the dimmers
(Ck #_ ).
•Locate the Circuit Breakers - Switches to the
left on the face of the Module to be removed.
•Move the switch toggles to the OFF position.
•Firmly grasp the top lip of the Module and pull the
Module directly out of the module bay.
To replace a dimmer module:
•Locate the correct circuit numbers, note there may be
a pair of circuits per each dimmer module.
with the appropriate shelf slots, slide the module in very
firmly to assure solid connections are made.
DO NOT SLAM MODULES INTO THE RACK!
•After carefully lining up the sides of the modules
