                Frequently Asked Questions

                hide show

                What is the current rating per channel for an L5504D2UP

                The current rating per channel is 2.5A

                What to do when C-Bus dimmer channel will not turn off ?

                - Initially check that the programming is correct.

                - If using LED lights, the LED may stay on when the channel is off, this is due to the leakage current being enough to power the LED, use of a 31LCDA may resolve this issue.

                - If using Halogen and  the channel will not turn off, there may be damage to the electronics on this channel - Electricians only to perform this check, disconnect the Active's , Neutral and Earth from the unit, remove the cable for the load on that channel then with a multimeter check between the Neutral and that suspect channel output, if you see a low resistance the Triac has shorted.

                - Advise not to use this channel and label as faulty, other channels on this dimmer should still be ok to use as per normal, alternatively you could return this unit for a quote on repair, note a repair may not be possible.

                What is the CBUS shutter relay

                 Part code is L5501RBCP

                What is the part code for the C-Bus Single Channel Shutter Relay for Blinds/curtains?

                The part number is L5501RBCP

                How do I determine if a fan is suitable to be used with the C-Bus fan relay unit

                Any fan which is switched via a 3 wire capacitor (low, medium, common) will be acceptable

                What is the part number of the wall mounting enclosure to suit L5501RBCP 1 channel C-Bus Blind/Curtain/Shutter relay?

                5501RE is the part number of the wall mounting enclosure to suit  L5501RBCP 1 channel C-Bus Blind/Curtain/Shutter relay.
