I'm replacing a set of STI Microsafe curtains with a new set of AB Guardmaster curtains with a MSR127TP Safety relay.

I'm in a bad way as this machine was already way behind on the production schedule when the old curtains died and I really don't have much time figure out the differences in wiring the new hardware to the control relays.

There are some similar terminals between the old controller and the AB relay, but there are some that I don't understand.

"MON1"
"MON2"
"MTS2"
"MTS1"

And there is a "Light Curtain Reset" push-button on the HMI enclosure wired into a group of terminals on the old controller.

"GND"
"Start"
"GND"
"RUN"

I emailed OMRON requesting a manual on Friday, but I haven't heard back from them.

If anyone has input that may help speed up the process, I'd appreciate any available...

Thanks,
Joey
