EXOR intelligent lighting Box

[Jimbear22]

This might be daft but i am currently doing remedial work on a commercial site and there are lights being served from a EXOR lighting box. Undertaking a continuity R1 and R2 at the incoming on the box i have continuity but at the light fittings nothing, i have changed the plug and the flex still nothing. My gaffer instructed me to change the box still the same. Has anyone had similar finds with these lighting boxes or am i missing a trick.

Are you testing from the outgoing terminals at the controller.

Which EX-OR box? you would need the detector plugged in or the live and switched wire terminals shorted out.

It's a exor cdw12u5 the pir is just Ethernet cable it has a rj45 plug on the back

Iam testing at the 600 by 600 light fittings

Are you linking the line and cpc at the dist board.

You won't be able to as the unit needs to have a permanent live to make the relays work. It might work if you link out in one of the luminaire plugs between emergency live and switched live. if not R1+R2 to the LCM and then the plug to the luminaire and add together. You could check this by comparing R2+Rn should be the same anothe could be a R2 test and loop.

Yeah linked at fist board

Yeah linked at fist board

As Ant says you are losing it through the controller. This needs taking out of the equation.

Yeah I took the lighting flex out of the controller today and joined it to the incoming singles hey presto continuity. But surely there is a earth path from the lighting fitting through controller in normal operation.

The path of the cpc should not be interrupted by the controller.

Yeah exactly what I thought

On it tomz mate. Thanks for everyone's help on this.

Yes, and neutral. On standard LCM's you can just link out the PIR/M. wave etc,but as this is a digital LCM and the detectors are on cat 5 RG45 plugs this is not possible you have to bypass the live switching of the LCM.
