Chapter 3 MSR300 Safety Relay
Global E-stop, Local E-stop
In the following example, the first MSR320P safety relay input module
provides a global E-stop, which stops groups 1, 2 and 3. The middle MSR320P
safety relay input modules stop groups 2 and 3. The third input module only
stops the outputs in group 3. The GSR solution stops outputs with the Single
Wire Safety connections on terminals L11 and L12.
For the GSR solution, you must press the reset button three times: the first
press turns on the DI safety relay with the dual-channel E-stops, the second
press turns on the DI safety relay with the single-channel E-stop, the third
press turns on the DI safety relay with the OSSD devices.
