Simple Supply Requirements
Single Phase at 40A.
One Leading Edge Dimmed Output
The 20A output is independently
regulated, protecting loads from voltage
surges and spikes.
8 Multifunction Inputs
Ideal for interfacing to other systems.
When activated, the inputs can be used to
trigger Tasks in the internal
programmable logic controller.
Many Control Options
Control of this device can be from a
combination of methods, eg. serial control
port, relay contacts, push button wall
stations, infra red receivers and
timeclocks. Easy high-level interface to
other popular AV control systems and
Building Management Systems (BMS) is
also available.
Simple Installation
Wall-mount enclosure with mounting lugs
facilitates installation. Cable knockouts
are provided, at the top of the enclosure
for supply and load cables, with data
cables at the bottom.

Troubleshooting
- If problems are encountered,
check the Troubleshooting section on page 7.
Special Programming
– This device will only
operate in basic modes unless programmed via a
computer. If programming is required, contact
your local agent for details. Once the data cable
is connected to the devices, the factory default
settings will allow any control panel to control all
channels in all dimmers.
Check Connections
– Treat this device as a
switchboard that has been shipped. Tighten all
load-carrying screw connections, as vibrations
from transport can cause MCB and terminal block
screws to become loose.
Power
Sources
– This device should only be
operated from the type of supply specified on the
front panel. This device
must
be earthed.
Output Circuits
– The load on a circuit should not
exceed the specified capacity of 20A. Loads
should be calculated to ensure that the overall
maximum capacity of 40A is not exceeded.
Optional Multifunction Inputs
– These inputs
are designed for dry contacts or SELV analogue
inputs only. Cables to these inputs must be
treated as SELV.
Mounting Location
– This device must be
mounted right way up, on a vertical surface (refer
to page 4 for mounting instructions). The
specified minimum clearance of 100mm for all
sides must be adhered to. Install in a dry, well-
ventilated location. Controllers may emit some
mechanical noise. Take this into account when
deciding the mounting location.
Data Cable
– The recommended cable for
connections to the serial port is screened,
stranded RS485
data cable with three
twisted
pairs.
Part
numbers
for
various
manufacturers are listed on page 6. This cable
should be segregated from mains cables by a
minimum distance of 300mm. If anticipated cable
runs are over 600 metres for serial cables, consult
your dealer for advice. Do not cut or terminate live
data cables.

TO REDUCE THE RISK OF FIRE OR
ELECTRIC SHOCK, DO NOT EXPOSE THIS
DEVICE TO RAIN OR MOISTURE.
DO NOT ENERGISE UNLESS THE FRONT
