Check the following list. If you are still unable to rectify the situation, contact your nearest Dynalite office. A complete list of
distributors worldwide can be found on the Internet at: http://dynalite-online.com/html/contacts.htm. 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 12V terminal voltages.
Disconnect network bus and restore power.
Replace control PCB.
Dimmer will not respond to control panel push
buttons.
Control panel incorrectly wired or 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.
Check ballast type. Check actual wiring against
ballast manufacturer’s diagram. Check 1-
10V/DSI, DALI Broadcast settings.
