Proteco controller & ACT5e keypad - keeps tripping

[JoeF]

Thanks for this

The system works perfectly without the keypad connected.

I have connected the keypad to an old physics lab power supply where I can read off the current draw - it seems in order at around 50 to 80ma.

I am going to circumvent the installed cable and run a quick test cable keypad directly to the box to see if as you suggest, there is some issue in the installed cable. I've always had a suspicion this cable was compromised on installation but its failure is intermittent (perhaps weather or moisture dependant etc)

Hi,

thanks for the reply,

please keep me updated with your findings.

Kind Regards 
Joe
