GHL Profilux Plus II Problems

[gatekeeperdi]

I have a GHL Profilux Plus II, a 4 unit dosing pump and a 6 socket powerbar. I have been using them for a few years without any problems but today the green power and yellow communication lights on the powerbar were flashing and none of the sockets were activated when they were programed to be on. I was using the powerbar to control two heaters controlled by the GHL temperature probe and only realised that there was a problem when the temperature of the tank water had dropped.

I have tried to reassign the sockets on the powerbar but it is still not responding although the doser appears to be working as it should.

Have you any advice as to how I might rectify the problem?

Thanks for any assistance you can give me.
