How do I troubleshoot a Sequel 2UX2 module?

First do Hard Reset on System.

If the Station is acting as it is trying to dim the lights then check for dimmer issue.

First remove Pig Tail from Module that has the circuit that is not working.

Using a True RMS Meter Set on DC measure the following With Station at full on

Black Wire to Yellow Wire Should Be 12 VOLTS DC.

Blue Wire to Black Wire should be 5VDC

Red Wire to Black Wire Should be 5VDC

If none of these are present Replace Dimmer Service Card

Now set the station at half way.

Make the same measurments again

You should still have 12 Volts on the Black and yellow wires.

Red to Black should now be 2.5VDC

Blue to Black should now be 2.5VDC

If these voltages are correct and lights are still not dimming Replace Duel SCR in Module. They can buy this at an Electronics parts house. Lead time is way to long.
