Have just got my gates operating.
System I have is a 2 wing gate, Liftmaster sub300M, CB11 controller, combined with a Daitem D5731GB Wireless system. System is operating with Remotes and wireless system.
I have few questions:
After the gates are fully open or closed, the motors continue to hum for about 15 seconds. Is this a problem? if so what have I to do to rectify problem.
The Motors are over running they should over run by about 3 seconds this is what gives the holding force in open or closed possition. If they are over running by 15 seconds then you need to reprogramme the limits so they only over run by max 3 seconds otherwise this will lead to the motors heating up and wearing out quicker.
The gates closes or opens even when I block the photocell beams, I am assuming this is not correct. The photocells I have fitted are the 771E/770E and are wired as per page GB-6 that is to terminal 23 and 24. Do I need to link out 21,22, and 23?
If you have 1 x set of photocells i would wire them into just the close circuit ie pins 22 and 24 then the gates will revesre upon closing. You dont need to link out the unused circuits.
Some times I need to leave the gates in an open position, can this be done automatically, if so how? I now turn off isolator!!!.
The only way to achieve this is with a switch wired into the system accross pins 17 & 20 this will hold the gates open untill the switch is releases. By Isolating the power in the open possition the motors will get confused and over run when you switch power back on and cause wear or damage to the motors.
Is there any other commissioning points need to be carried out?

You need to check that the system is safe and complys with the EN Safety regulations please read through the attatched regulation guide which in EN Law regarding Electric Gates.
