Thanks for a clear description of what you have done Your connections seem to be correct
You have programmed 4 to open gate to Pulse Output 1 providing a dry contact to the Gate strike
First you should confirm if the gate strike works by shorting the points connected to the RLY01. This should release the gate. If it does not then the gate strike has a problem. If it does, then the fault lies on the Comfort side
Also (if the strike does not release) check if the gate strike is supposed to operate via dry contact (ie closed contact) or you need to supply a voltage
Assuming shorting the contact does open the gate, you can measure the voltage on both ends of the gate strike contact. When the relay is not activated there should be a voltage across them. Be careful there as it may be 230V! When the relay is activated during the 1.5 seconds of the pulse the voltage should drop to 0
If it does not then there may be a wiring problem from the gate strike back to the RLY01 or a problem with the outputs
A systematic check like this should quickly narrow down where the problem lies
thanks for the fast response. As far as I know the strike needs a 12v pulse for about 1 second. I am not sure whether the RLY01 is simply switching or whether it is supplying this 12v from the comfort's 12v
The RLY contacts do not supply 12V, they just provide a closed contact to the strike, which is termed a "dry" contact
If you want to supply 12V DC (and you should check if that is true) you need to connect 12V to one of the contacts of the RLY01 and connect the other contact to ONE of the terminals of the strike. Check the documentation for the door strike to see exactly what it needs
That depends on what current is taken by the door strike. Comfort supplies a maximum of 1 A for alll devices which is connected to its 12V. Slaves with their own transformer also supply 1 A
Door strikes may require a lot of current, which you can find out from checking its specs. In that case you should get it from another power supply
In order to have a complete post. I had eventually solved this one. The door strike needed a 12v 2A power supply. I used an external one and all worked just fine.
For the beginners amongst you please note that the 12v input on the RLY01 board does not supply 12V to the relay output but is used to trigger the relay into closing. You may be familiar with how a contactor in an AC scenario works.
