LiftMaster SUB300M + CB11 fault
#1
hello!

Around 3 years ago we fitted 2 sets of twin leaf gates, both with the exact same components, (a pair of SUB300M motors, and CB11 control panels with lift master photo cells). around a week after the gates were fitted the master leaf of the second pair of gates were forced open by a old friend. since this event we have had hit and miss problems with the pair of gates, mainly consisting of the gates not closing consistently (stopping short and tripping the RCD ), we changed out the motor last year and all was fine for a while but recently we have had problems again (although the gates are closing and opening properly while they are working fine).

On closer inspection it appears that the CB11 seems to trip the RCD when it resets after programming both leafs. any ideas on this would be appreciated as were getting close to giving up. i dont want to spend the money on new motors and control panel without asking you guys for help.


thank you in advance

Chris
