WMX SERIES DIMMER OPERATING MANUAL
1.0 Introduction
The JANDS WMX is a high quality, rugged, 12 channel, 2.4kVA per channel
(10A/240V) dimmer rack specifically designed for contracting / theatre applications.
A separate wall bracket simplifies the installation process. It allows cabling to be routed
to the dimmer location prior to the installation of the actual dimmer units, providing the
contractor with the ability to fit off the dimmers when the site is secure.
An optional extended wall mounting bracket, provides the end user with an economical
and compact method of routing cable duct behind the dimmer rack.
Features
• 12 x 2.4KW dimming channels
• DMX-512 digital control protocol
• DMX terminating switch
• Suitable for permanent installations
• Soft turn on characteristic
• Low acoustic/electrical noise
• Toroidal output chokes
• Circuit breaker protection of output devices
• Three mains phase indicator LEDs
• Built in test facilities
• Dimmer curve set for linear relationship between the control input and output power
• Compensation for fluctuations in the mains supply voltage and minimises the effect
of superimposed control tones, ensuring a constant light output and increased lamp
life
• May be rack mounted or attached to a wall by means of supplied mounting bracket
• Microprocessor control
• Temperature controlled cooling fan

seconds on - 2 seconds off.
7. FAULT LED: A red LED flashes in the presence of a fault. In normal operation this
LED should be off.
8. PHASE LEDs: Three blue LEDs (one for each phase) indicate that the three phase
mains supply is available.
9. DMX IN SOCKET: Standard 5-pin AXR connector accepts DMX-512 signals from
controller.
10.DMX LOOP SOCKET: Standard 5-pin AXR connector links the DMX-512 signals
to other dimmers or devices.
11.TERMINATE SWITCH: In the right hand Loop position it links the male IN
socket to the female LOOP socket, continuing the DMX signal to other devices. The
left hand Terminate position is used to terminate the DMX signal if this unit is the
last device in DMX chain.
12.CABLE ENTRY: Removal of the hole plug provides access for a 32mm cable
gland. This cover should remain in place for safety reasons unless using the hole for
cable access.
13.AIR INTAKE: This is the main entry point for air cooling of the dimmer. DO NOT
obstruct this entry and keep it free of dust.

WMX SERIES DIMMER OPERATING MANUAL
3.0 Getting Started
The WMX would normally be wall mounted before any wiring is terminated. Refer to
section 6.0 Installation for details.
3.1 Connecting power
The WMX dimmer is supplied with 4 rising clamp terminals for the connection of
incoming mains power and a ring star connector for the incoming protective earth wire.
To gain access to the input terminals, it is first necessary to remove the front cover that
wraps around to the control panel and circuit breaker side of the dimmer, followed by
the socket outlet panel. Note: The earth wire can be removed from the front panel by
means of a spade connector on the bottom right corner of the panel, allowing the panel
to be placed to one side while working on the dimmer.
Connect the incoming mains power cables to the rising clamp terminals on the lower
right side of the main circuit board. The three phase conductors shall be connected to
the terminals marked Active A1, Active A2 and Active A3. The neutral conductor shall
be connected to the terminal marked Neutral. It is important that the ends of the
conductors go under the circuit board between the flat of the rising clamp and the
copper bracket on the circuit board. Do not screw down directly onto the wire.
Figure 3.1 Mains Power Termination
To connect the earth wire, strip the insulation back approximately 35mm, wrap the bare
end around the supplied star lug and crimp with pliers (Figure 3.2). Secure crimped
earth wire to stud using supplied washers and nut (Figure 3.3).

If the frequency needs to be changed to 60Hz, refer to section 3.2 Setting the mains
frequency before continuing. Check that the securing screw has been inserted through
the lower right corner of the chassis into the wall mounting base plate (refer to section
6.6 Mounting the dimmer to the bracket for more information).
Replace the cover panels, starting with the socket outlet panel. When replacing the
covers, check to make sure that the two earth straps are connected to the chassis and the
front cover for the control and circuit breakers. If not, push connectors onto the tabs
marked with the earth symbol and the replace covers.
3.2 Setting the mains frequency
The WMX can be configured to run from either 50Hz or 60Hz mains power - as
supplied from the factory it is configured for 50Hz. To change the dimmer to 60Hz,
change the three jumpers to “60Hz” as per Figure 3.4.
Figure 3.4: 60Hz Jumper Locations
3.3 Powering up
Turn on the power and check that the three PHASE indicator LEDs are on before
connecting any loads. If the PHASE LEDs indicate a fault condition (refer to section 5.3
Phase fault indication), power down and remedy the fault before trying again.

If all is well, power down and connect loads.
3.4 Connecting loads
The standard output connectors are twelve 10 amp Australian sockets (Export models
may differ from these configurations). Ensure any plugs are pushed firmly into their
sockets and/or all screw terminals are tight.
The WMX will drive most incandescent loads as well as some downlight transformers
(suitable for leading edge dimmer control), fans, and dimmable fluorescent tubes. The
load should be greater than the specified minimum (refer to section 8.0 Technical Data
and Specifications).
3.5 Connecting DMX-512 input
The input signal to the dimmer should conform to the AMERICAN NATIONAL
STANDARD (ANSI) E1.11-2004 ENTERTAINMENT TECHNOLOGY USITT DMX-
512-A specification. Plug the DMX signal to the “DMX IN” socket. The DMX signal
may be daisy-chained to the next dimmer via the LOOP connector.
When power is on the DMX LED indicates the presence of DMX signals.
The DMX receiver input is protected against extreme over-voltages across any input
pins and from any input to chassis. The “terminating” resistor is not protected against
over-voltages.
3.6 DMX termination
In any DMX-512 system the signal should be terminated at the last dimmer or receiver
in the chain, and the WMX can provide this function. To terminate the DMX signal, set
the front panel slide switch from LOOP to the Terminate position. Note that in this
position no signal is present at the LOOP connector.
3.7 Power-up sequence
When powering up lighting systems, the following sequence should be used:
1. First the control desk;
2. Then any softpatches and/or DMX receivers;
3. Finally the dimmers, preferably one at a time starting from the first dimmer rack in
the DMX loop.
This procedure minimises the risk of producing the lighting equivalent of an audio
“thump” and prevents damage to lamps, dimmers, and other controlled devices.
Use the reverse procedure when powering down.
