Hello,
I'm having trouble with a Came SDN4 gate. The controller is ZN7.
The gate stays open, but it occasionally close when I leave it with the power on.
I noticed there is no power to one of the photocell emitters (DIR10), and sometimes the power is back on by itself for an hour or so.
The controller board display shows C1 which to my understanding, it means it kept open by the photocells.
So I tried the following but to no avail.
- Replaced the photocell
- Replaced accessories fuse
- Reconnected all the wiring to ensure to have contact with the terminals.
I measured the voltage of the photocell power line, and it read around 5-6v. Then I measured the power points(10 & 2) on the terminal, it only outputting around 14v, which should be 24v.
Also measured the transformer and it has the correct 24v AC output.
I'm stumped at the moment, the next thing I would do is to replace the controller board, but I don't want to spend £130 before getting advice from you guys.
Did anyone have a similar issue?
