                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 are the C-BUS Relay part numbers?

                You have several options for relays, Catalogue numbers and information below.

                L5504RVF, L5504RVFP** - 4 Channel voltage free relay - 10amps per channel
                L5508RVF, L5508RVFP** - 8 Channel voltage free relay - 10amps per channel
                L5512RVF, L5512RVFP** - 12 Channel voltage free relay - 10amps per channel

                L5504RVF20, L5504RVF20P** - 4 Channel voltage free relay - 20amps per channel

                L5508RELVP - 8 Channel Extra Low Voltage Relay

                5101R - Single and Two Channel 250v AC 10amp relay
                5102RVF - Single and Two Channel 250v AC 10amp Voltage Free Relay

                ** Any part number that has a 'P' after the part number for Din Rail mount units does NOT include a C-Bus 200ma Power Supply..

                What are the C-Bus Channel Limitation for Current Measurement Unit?

                There will be limitations on how many CMU channels that can be utilized, depending on the device being used. This is due to memory limitations of those devices, as to how much historical data can be retained.

                Below is a list of the maximum CMU Channels that can be used. Each CMU has 4X Channels per unit.
                Each CT Coil has a selection range of either 0-40 and 0-80 AMP Range - This is software selectable..
