Hi there,

We have just replaced the posts that were housing one pair of photocell sensors to our gates. That meant disconnecting and rewiring the photocelles. Everything has been replaced as it was however on inspection there is now no power to the control unit at all. All fuses seem to be ok.

I wonder if anybody has any ideas? There is nothing showing in the LCD. 

Thanks much!

You will need to check the board is still receiving its mains feed in by using a multimeter, or checking the supply RCD hasn't tripped. If all of this checks okay you may need to check the board does not have any damage on it from insects on the back of the PCB by removing it from its enclosure and looking at it.
