Safety-related shutdown with 3RM11/3RM13 Failsafe motor starters

General description
In the case of 3RM11 / 3RM13 Failsafe motor starters, safety-related shutdown is achieved
by removal of the control voltage (A1 / A2). As an alternative in the case of units with a 24 V
DC supply voltage, safety-related shutdown can be performed by canceling the ON
command (IN1/IN2).
SILCL 3 to EN 62061, PL e/Cat. 4 to EN ISO 13849-1 can be achieved with both shutdown
methods. To achieve SILCL 3/PL e/Cat. 4 for the safety function, all components of the
safety function (detecting/evaluating/reacting) must be designed accordingly.
In the case of 3RM11/3RM13 Failsafe motor starters, the OFF state is defined as the safe
state. 3RM11/3RM13 Failsafe motor starters are self-monitoring in compliance with SILCL
3/PL e and therefore do not need to be monitored in the feedback circuit of the upstream
evaluation unit/control.
Loss of the safety function during hybrid operation of Failsafe and Standard motor starters.
Can cause death or serious injury.
Hybrid operation of 3RM10/3RM12 Standard motor starters with 3RM11/3RM13 Failsafe
motor starters in safety-related applications is not admissible.
Only ever use safety-related motor starters (3RM11 Failsafe and 3RM13 Failsafe) in safety-
related applications.
Note
Fault signaling output (95-96-98) behavior in the event of safety-related shutdown
The fault signaling output (95-96-98) resumes its original state in the event of safety-related
shutdown via the control supply voltage. If the fault is still present after reconnection of the
control supply voltage, the fault signaling unit becomes active again. If an overload was
detected before shutdown, the remaining cooling time is saved and elapses after
reconnection of the control supply voltage.
