Troubleshooting
Specification
SYMPTOM
Dimmer does not operate at all. No Service LED
activity. Power supply indicator LED on PCB not lit.
Power supply indicator LED lit, but no Service LED
activity.
Dimmer will not respond to control panel push
buttons.
Dimmer operates properly but circuit breakers keep
tripping.
Fluorescent lights won’t dim.
PROBABLE CAUSE
Incorrect connection of mains supply, or no power
available.
Supply voltage too low, short circuit on network.
Control PCB faulty.
Control panel incorrectly wired or incorrect
configuration.
Instant tripping:- short circuit on load.
Delayed tripping:- dimmer overloaded.
Wrong type of ballast or ballast incorrectly wired.
ACTION
Check power supply to dimmer. Check Line and
Neutral input connections.
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.
Check operation of LEDs on control panel. Push
button on panel and study response of service LED.
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.
Check ballast type. Check actual wiring against
ballast manufacturer’s diagram. Check 1-10V/DSI
settings.
Check the following list. If you are still unable to rectify the situation, contact Ex-Or. Please ensure that you have completed the following
prior to calling our technical support department.
