The MSR41 or MSR42 can have up to three MSR45E safety relays inter-connected. Each module requires a ribbon cable connector to makethe interconnection. The table shows the cat. no. for each ribbon cable connector as well as the optical interface for the programming of theMSR42. Programming of the MSR42 is only necessary for advanced operating modes or connection of additional devices.
Optional Safety Relay Interface (accessories for MSR41 or MSR42 Controllers)

Circuit StatusThe light curtain is clear. K1, K2, K3 and K4 are off. The motors are off and ready to run.
Operating PrincipleSTARTING: Momentarily press the Start button. The OSSD safety outputs and the safety contacts 13/14 and 23/24 close. The contactors K1-K4 energize, and the motors M1 and M2 start.STOPPING: Breaking the light curtain causes the OSSD safety outputs and the safety contacts 13/14 and 23/24 to open. The contactors K1-K4 drop out and the motors coast to a stop.
Removing the object from the light curtain will not cause the motor to run. The operator must momentarily close the Start switch to turn the motor on.
Fault DetectionUpon successful completion of internal checks on power up, the GuardShield light curtain energizes its outputs with no objects present. The GuardShield light curtain outputs turn on. If a crossfault is detected, the GuardShield light curtain goes to a lockout state with its outputs off. After successful completion of internal checks, the MSR41 checks the signals from the light curtain. If it’s okay, the MSR41 then checks the status of the K1-K4 contactors. If one of the pair of contactors fails in the actuated state, the other contactor will disconnect the motor. The MSR41 will detect the faulted contactor and will not allow the motor to restart until the fault is corrected.
RatingsThis circuit can meet the safety performance requirements of PLe per ISO13849-1: 2006 and SIL CL3 per IEC62061:2005. This circuit executes a Category 0 stop.

Circuit StatusThe light curtain and muting sensors are clear. K1, K2, K3 and K4 are off. The motors are off and ready to run.
Operating PrincipleSTARTING: Momentarily press the Start button. The OSSD safety outputs turn on and the safety contacts 13/14 and 23/24 close. The contactors K1-K4 energize, and the motors M1 and M2 start.MUTING: The MSR42 must be configured for two sensor L-type or T-type sensing. When the object passes by the sensors in the proper sequence, the light curtain becomes muted. The muting process is complete when the object passes by both sensors, and the light curtain becomes active again.STOPPING: Breaking the light curtain causes the OSSD safety outputs and the safety contacts 13/14 and 23/24 to open. The contactors K1-K4 drop out and the motors coast to a stop.
Fault DetectionUpon successful completion of internal checks on power up, the GuardShield light curtain energizes its outputs with no objects present. The GuardShield light curtain outputs turn on. If a crossfault is detected, the GuardShield light curtain goes to a lockout state with its outputs off. After successful completion of internal checks, the MSR42 checks the signals from the light curtain. If it’s okay, the MSR42 then checks the status of the four sensors and the K1 and K2 contactors. If a sensor is shorted in the ON state, the MSR42 will not allow the OSSD outputs to turn ON. If one of the contactors fails in the actuated state, the other contactor will disconnect the motor. The MSR42 will detect the faulted contactor and will not allow the motor to restart until the fault is corrected.
