Quick Troubleshooting Guide:
Controller doesn't power on:
- Check the power supply, circuit breakers in the main panel, and ensure there is
voltage at the power terminals of zone 1 on the controller.
- Check fuse F1.
Controller powers on, but the lighting doesn't:
- Check on the controller screen if the output intensity of the corresponding zone is set
above 0%.
- Verify if the manual mode is working. Gradually increase the level. If the lighting turns
on, your low level needs to be adjusted. Adjust your low level with the “minimum
adjust” potentiometer.
If the lighting still doesn't turn on at 100% in manual mode, check fuse F2/F3 according
to the zone.
If the manual mode works, but the displayed level is 0% in master mode, the issue is in
your schedule programming.
If the output shows 0% in slave mode, check if the input voltage is above 0V. If the
controller displays 0V at the input, measure the control voltage at the 0-10V input
terminals with a multimeter. If the measured voltage is also 0V, the problem lies with
the external master device or the connection between the two.
If there is a voltage at the input terminals of 0-10V, and the controller doesn't detect it,
check the polarity of the connection. If the polarity is correct, the controller may be
faulty.
Controller powers on, but the lighting doesn't dim:
- Check if the manual mode works. If the manual mode doesn't work, the controller
may be defective.
If the manual mode works, the issue may be with the programming or an external
master device, as described above.
