SYMPTOM
PROBABLE CAUSE
ACTION
Load Controller 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 Load Controller. 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.
Load Controller 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.
Load Controller operates properly but circuit
breakers keep tripping.
Instant tripping: - short circuit on load.
Delayed tripping: - Load Controller overloaded.
Check load wiring for short circuits.
Verify Load Controller 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 DRC810DT to
ballasts not installed.
Check ballast type. Check actual wiring against
ballast manufacturer’s diagram. Check 1-10V/DSI
cable and settings.
