from a „safe controller" with semiconductor outputs,
the residual voltage must be < 5V DC. Interruptions
≤ 3 ms are filtered.
EMERGENCY STOP
Integrating a hybrid motor starter into an EMERGENCY
SToP chain is pictured in Fig. 5.
In this application, the control circuit is switched and
not the control supply voltage.

Motor overload protection

All safety-relevant functions are implemented by the hy-
brid motor starter, without external influences. Special
circuit technology is not necessary.
Wiring of the load current circuit should be realized as
described in the examples provided. The module cur-
rent supply can however be directly connected to the
voltage source, without the PSR safety relay. The same
is applicable for the control.
Motor with brake
If a motor with brake is connected (in the motor ter-
minal board), the 400V AC brake has to be connected
to the 2 / T1 and 6 / T3 connections. A 230V AC brake
must be connected with 4 / T2 and the neutral point
of the motor.
Note: The motor current monitoring must be increased
by the value of the brake (nominal brake current).

sidual voltage must be < 5V DC. Interruptions ≤ 3 ms
are filtered.
Note: Switching off the control voltage supply with
a controlled motor always results in wear in the
hybrid motor starter! This switch should only be
used if no more than 10,000 shutdowns can be
expected over the entire lifespan of the system. If
the switch-off is performed, for instance, from a
„safe controller" with semiconductor outputs, the
residual voltage must be < 5V DC. Interruptions
≤ 1ms are filtered.

Replacing fuses

The fuses are rated so that they only need to be re-
placed after damage. Mains outages or disconnection
of fuses will be signaled as a phase failure upon activa-
tion (PWR + Err flash and L or R light up).
