ELK - Overcurrent Error with M1RF2G board attached

I finally started bench testing my ELK unit last night. I got everything hooked up (ELK M1 Gold, M1KP2 keypad, M1XEP ethernet interfact, and the M1RF2G wireless board) and I was getting an overvoltage overcurrent error on the keypad. When I disconnected the M1RF2G the error stopped.

I had both the keypad and M1RF2G wired into the control board directly - basically home run each unit to the board. I verified the JP1 jumpers were installed on both the keypad and the M1RF2G since they are both acting as end of line devices.

Any suggestions to fix the overvoltage overcurrent problem? I'm sure it is a user error, but since I'm brand new to all of this, I can't see the problem.

Thanks,
 
The XEP has (had?) a very high current draw rating, but I don't know it it really used the 2A (IIRC) or whatever it claimed. I don't know what the RF2G board draws as I don't have one. But you may actually be drawing too much current without an aux power supply. There is a sequence from the keypad to show the actual current draw, sorry I don't remember them now, but it is documented. Check that and see if the current number makes sense or if maybe you have a tiny short circuit or maybe you are just overloading.
 
OK. I'll check the total current used. I just thought it was weird that I have so little connected and yet still got the error. The XEP has it's own power supply, so I thought that the only devices drawing power from the unit is the single keypad and the RF2G. If the RF2G board really uses that much power, I would have thought it would come with it's own power supply.

I'll read through the documentation a little closer and see what I can find.
 
Overcurrent is usually from too much equip like Wayne said. But it does not sound like that is your problem. I have an RFG2, 2 keybads, XSP, etc and am still good. It can also be a short circuit (like Wayne also said) or even loose connection. I once has a loose connection on a Beenie by a keypad and got the same error. I would definitely check your connections and make sure they are right and tight.
 
I have two keypads, a M1XIN, a M1XSP, a RFG2, a M1RB and a few motion detectors, CO detectors, and smokes with EOL Relays etc. running off of my panel at about 750 ma or so (measured it just yesterday).

I would double check the wiring again. SLIGHT chance of a bad board but I doubt it.
 
Well I reconnected the RF2G board and it doesn't give me an overcurrent error. So it was probably a loose connection or something like that. It works fine now.

Thanks for the help. I'm just glad it was something stupid on my part. :)
 
If you momentarily short out one of the power supply outputs and the PTC fuse opens, an "Overcurrent" message will be on the keypad. If the circuit that was shorted is still drawing its normal current, the PTC fuse may not reset until all power is turned off to allow the PTC fuse to cool down and reset. The "Overcurrent" message should then disappear from the keypad.
