9.2 Safety door (emergency stop)
In applications where safety shutdown is a normal operating
state,e.g., for safety door or two-hand applications, it is the
control circuit that is switched and not the control supply
voltage.

3 Emergency stop
4 Reset button
If shutdown is performed, e.g.,from a “safe controller” with
semiconductor outputs, the residual voltage must be <
5VDC.
Interruptions 3ms are filtered.

9.3 Motor protection
All safety-related functions are implemented by the hybrid
motor starter without external influences. Special circuit
technology is not required.
The wiring of the load circuit should be implemented as de-
scribed in the examples.
However, the module power supply can be connected di-
rectly to the voltage source, without the PSR safety relay.
The same applies for the control.
The motor currents are measured at phases L1 and L3 and
monitored for symmetry.
In the event of a deviation of 33%, the motor shuts down
after 2minutes.
In the event of a deviation of 67% (e.g.,phase failure), the
motor shuts down after 1.8seconds.
The deviation can be calculated using the following formu-
las.

9.4 Motor with brake
If a motor with brake (connection in the motor terminal
board) is connected, the 400VAC brake must be linked to
the 2/T1 and 6/T3 terminals. A 230VAC brake must be con-
nected to the 4/T2 terminals and the star point of the motor.
9.5 Auxiliary relay connection
Auxiliary relay (e.g. PLC RSC 230UC/21, order no.:
2966207) for activating external brakes or acknowledge-
ments, e.g. to the PLC, must be connected to the 4T2 and
N connections of the system.
NOTE
Increase motor current monitoring to the nom-
inal brake current. This should be set accord-
ingly on the hybrid motor starter.
