The following events indicate the "Malfunction" status:
● DEVICE LED flashes red
● FAILURE LED shows a red light
● Fault signaling output active
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 u
nit 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.
