Rockwell Automation Guardmaster Allen-Bradley 440R-S35001 - Two Zones, Global E-Stop

Rockwell Automation Publication 440R-RM003A-EN-P - July 2021 21
Chapter 3 MSR300 Safety Relay
Two Zones, Global E-stop
In the following example, the MSR300 safety relay has a global E-stop that
turns off outputs groups 1, 2, and 3. Group 2 and 3 inputs control their
respective outputs.
The GSR relays can use the Single Wire Safety signals on terminals L11 and L12
to perform the same global E-stop function. For the GSR system, the reset
button must be pressed twice: the first press turns on the DI safety relay with
dual-channel E-stop, the second press turns on the other two DI safety relays.
