Contour Dimmer Performance Specification
Mains Input
Mains input connection 3 phase (Star) direct to bus bars via various gland knockouts
(Glands not supplied)
Delta 3 phase requires special bus bars
Voltage input range Dual range autosensing - 180v to 260V and 90V to 130V
Mains frequency 45Hz to 65Hz continuous auto sensing and auto tracking
Over voltage protection up to 450V phase to neutral
Power Supply protection Electronic (PTC) fuses with secondary backup
internal 1Amp 20mm fuses
Power consumption Less than 15W (no load), per phase
Earth leakage Less than 2.0 mA
Dimmer Outputs
Phase controlled outputs 12 channels
Output protection 12 Thermomagnetic circuit breakers each with neutral
disconnect, breaking capacity to EN 60898: 1991 (4,500 Amps)
Triac / SCR ratings Controlling devices are specified to not less than 2.5 times the
continuous maximum current.

Control Electronics
Controls Three digit 7 segment LED display, 18 buttons
Channel Test One button per channel to override inputs to user set levels
Preheat Variable 0 to 50% for each channel
Topset Variable 50 to 100% for each channel
Output control laws Normal, Linear, Square or Switch laws for each channel.
Switch point is at 50% (nominal).
Mains turn on Anti flash operation
Control resolution From a standard DMX input resolution of 256 steps, 16 bit law
is used to give a resolution equal to greater than 6500 steps.
Hardware and Software
Input Mode Switch
‘DMX ONLY’ No analogue input. If DMX signal lost,
last data received is held
; if
no DMX input present, then ‘DMX ONLY’ LED blinks. When a ‘lost’
DMX signal is received again, the outputs respond without any fade in
time.
‘AN DMX’ DMX and analogue data mixed on a “highest takes precedence”
basis; if no DMX input present, there is a delay (fixed at about 2
secs), then a fade to analogue input level (or zero if no analogue
input) over a fixed time.
NOTE: All DMX new data or data loss is faded up and faded down at the fixed rates shown above.
DMX Input / Output
Input DMX connection directly to input terminal blocks, DMX THRU
connection may be “daisy-chained” directly to other dimmers.
Input isolation Optical isolation to withstand 240V, with electronic front end giving full
RS485 sensitivity
Loading Less than one unit load
Input protection Special filter circuit to remove line transients
Addressing Grouped channels 1 to 12 together, select channel one address only.
Analogue Input
Analogue input + 10Volts / - 10Volts autosensing via two locking DINs on rear panel
Input impedance 40K ohms
Overload capability +/- 40V continuous
DC output 20V nominal supply to DIN connectors, sw or - via rear panel
DC output specification 18V to 28V, maximum current 200mA (electronic fuse)
DMX Status Lights
OK LED ‘ON’ Correct length break is being received and data is valid. NOTE -
Contour ignores any non zero headers
ERROR LED ‘ON’ Any data byte giving receive errors, e.g. overrun or incorrect stop bit.
Both LEDs ‘ON’ together Most likely that the fault is in the DMX cable with lines 2 and 3 swapped
(+ and — data).
