Bypassing Capacitor For Low Wattage Devices
WARNING: Ensure safe isolation procedures are followed before removing the covers
If in doubt, do not proceed and contact a local qualified, or suitably skilled, electrician
Symptoms/Issue
My low wattage device glows or continues to operate, when the relay is off.
Description/Explanation of Issue
This is due to a capacitor installed across the relay to meet the CE requirements for larger wattage devices.
In CE (and UKCA) regions, this capacitor must be installed when dimming loads >= 1 kW
Fix/Solution
If you find that you need to install this dimmer with low wattage devices, the capacitor can be bypassed by moving the appropriate channels jumpers.
- Jumper position A - Capacitor active
- Jumper position B - Capacitor bypassed
The jumper (circled red below) is located to the right of the relay on the Triac PCB:
