Please ensure that you have completed the following prior to calling our technical support department.
Check all symptoms in the Troubleshooting list
Check for any deviations between the installation and the installation instructions
Make a list of the model numbers of all devices used in the system
SYMPTOM
PROBABLE CAUSE
ACTION
Dimmer does not operate at all. No Service LED
activity. Power supply indicator LED on PCB not
lit.
Incorrect connection of mains supply or no
power available.
Check power supply to dimmer. Check Line
and Neutral input connections.
Power supply indicator LED lit, but no Service
LED activity.
Supply voltage too low, short circuit on
network.
Control PCB faulty.
Check supply voltage is at least 75% of rated
voltage. Check 5V & 12V terminal voltages,
5V supply must be present. Disconnect
network bus and restore power. Replace
control PCB.
Dimmer will not respond to control panel push
buttons.
Control
panel
incorrectly
wired.
Incorrect configuration.
Check operation of LEDs on control panel.
Push button on panel and study response of
service LED.
Dimmer operates properly but circuit breakers
keep tripping.
Instant tripping: - short circuit on load.
Delayed tripping: - Dimmer overloaded.
Check load wiring for short circuits.
Verify dimmer loading with current tester
(don’t forget to de-rate for low power-factor
loads and transformer losses). Check that the
breaker terminals are tight.
Fluorescent lights won’t dim.
Wrong type of ballast or ballast incorrectly
wired. Control cable from dimmer to ballasts
not installed.
Check ballast type. Check actual wiring
against
ba
llast manufacturer’s diagram.
Check 1-10V/DSI/DALI cable and settings.
