Hello all,

I need some help wiring some safety edges into an existing safety circuit. its a 2 wire edge that were adding to a roll up door to create an estop condition if pressed. I am putting 3 of these on both the front door and back door of the machine. I have been informed by the manufacturer to add the edges in series to 33KM1 and 34KM1. 3 on one and 3 on the other. Using the picture i provided of the actual contactors and there current setup where exactly would i need to connect the two wires off the 3rd edge of each door to ensure pressing the edge creates an estop condition? I dont want to mess anything up here so specific answers here would benefit me most. I seem to understand wiring a new series circuit but i get confused when breaking into an existing one to add a device to it.

Thanks guys.

 

This is NOT professional advice! I STRONGLY recommend you get in touch with either the machine OEM or a local integrator with safety experience. Not a slam against you at all (we all started out there), but this is a circuit designed to protect people from injury/death and if you're having trouble with modifying a series circuit this may not be a project for you without some good on-site oversight.

It's hard to say for sure with only one sheet of the drawings, but I would definitely not do it that way. The Reer Mosaic is a programmable safety controller. Based on inference and Google translate, it looks like there are 3 interlock devices and an e-stop button, filling up its inputs. I would purchase a MOSAIC-MI8 ($274.00). Wire each safety edge to its own pair of inputs and add it to the program that way.
