Tallbloke Posted January 17, 2007 Posted January 17, 2007 Gents, I have a bit of a problem with an Elvox system and a Came gate controller. The PTO on the handset, which is intermittant and sometimes the whole thing stops working, the call tone, the code entry and the AV and the only way to release the gate is via radio fob. I got the thing working for a while after swapping the pairs round in the ground sensor loop relay. This would suggest that the PTO pair from the monitor aren't clean. If I used an AC relay to isolate the PTO pair, would that work. Or am I barking up the wrong one. I've had to leave the PTO out so the rest will work. , TB
luggsey Posted January 18, 2007 Posted January 18, 2007 The PTO is normally AC, the came gate depending on model will be 24 volt or 240 volt. Either way it's input for gate open will have to go via a relay. I would suggest you may have the output of the gate controler mixing with the intercom? ----------------------------------------------------------------------------------------------------------------------------------- Life is like a box of chocolates, some bugger always gets the nice ones!

Guest Posted January 18, 2007 Posted January 18, 2007 Came gate open is normally open going closed, volt free on the pcb, what's the model of the gate controller ? Swapping the loops pairs wont accomplish anything, its a problem with the elvox system and voltages being sent where they should not be. Using a relay from the elvox to the Came controller should solve the problem. Depending on the operation you require it will be necessary to wire the command into different terminals on the came board ie open auto close open stop close open ect

You could connect wires to spare button instead then gate can be opened at any time even without being called.

Or if there are not fit a spare button on the monitor rather than mess with a relay that can go wrong in the future. maplins do hundreds of styles and can be fitted in seconds with a cordless and a bit of solder.

Cheaper is to use the PTO switch but feed it with the control signal from the came PCB, done that several times when interfacing intercom to gates. (I don't know if your PTO is PCB mounted or not, I just slice the tracks and buzz on new cables) FWIW I don't think the Came PCB gate open terminal would be totally volt free, it will either have a signal on it or be open collector, I can check mine if it's the same one? A relay in the came control box would be pretty easy as the box is pretty big if you want to do it that way? (The one I have here is for the Frog, brinnngggggg dinnnngggg a dinggggg!!) Sorry daft fit. ----------------------------------------------------------------------------------------------------------------------------------- Life is like a box of chocolates, some bugger always gets the nice ones!

Sorry daft fit. You can use 3 i think control panels for the Frogs off the top of my head. Just depends what your using it for and the voltages. Same applies for the ATI or the rest of the range N/O Volt free is the open type requested by came.

Ever seen the 24 volt one melt the transformer? All you need to do is mount the IRTX tooo far away and the bloody panel melts! No fuse blows.... My confusion over the N/O contact, I thought you were saying the Came PCB had volt free to open the gate??? ----------------------------------------------------------------------------------------------------------------------------------- Life is like a box of chocolates, some bugger always gets the nice ones!

Ended up switching to Nice equipment for that, and very good it is too, especially the auto set up sequence. The fact as well its so good at obstruction detection you can even (don't please but i did test this) not even use safety beams in a pedestrian environment.
Tallbloke Posted January 18, 2007 Author Posted January 18, 2007 As always, your ideas are appreciated. A relay looks favourite at the moment. , TB
