Manual (remote acknowle gement point)
Connect a button (N / O contact) between the MAN
and RES terminals.
An acknowledgement is triggered as soon as a positive
edge is detected at the MAN input - button pressed
briefl y. If a negative edge is not identifi ed after approx.
2s, the hybrid motor starter adopts the error status
again.
Automatic
Establish an electrical connection between the RES and
AUT terminals.
After the bimetal monitoring has been triggered and
the subsequent cooling, the device performs an auto-
matic acknowledgement.
The RES terminal provides the voltage for the reset.
In variants with a rated control supply voltage of 24V
DC, this is 24V DC.
Fee back
As soon as the hybrid motor starter detects an error, the
reply relay is switched, i.e. the N / O contact is closed or
the N / C contact is opened. This behavior corresponds
to that of a motor overload protection relay.
The feedback is for signaling purposes only and is not
part of the safety chain. It is thus not included in the
safety monitoring.

1. Make sure that the 24V DC control voltage is applied,
no R or L activation is taking place and that no error
message is displayed.
2. Open the cover.
3. Pre the et / re et button for more than 6 to
change to the „Parameterization" mode – the green
PWR LED fl ashes once.
Note: In Parameterization mo e, the LED are
witche off every 2 for 0.3 to i tingui h thi mo e
from other operating mo e .
4. Set the nominal current of the drive using the 240°
potentiometer. The nominal current is specifi ed in
16 stages. The four LEDs show the set current.
5. Store this value by pressing the set / reset button
again (non-volatile area of the data memory).

6. Press the set / reset button for more than 2s (and
less than 6s) to display the set current for 3s.

6. Application example

Safety oor (EMERGENCY STOP)
In applications where the safety switch-off is a normal
operating mode, such as in the case of safety door or
two-hand applications, a circuit as per Fig. 4 should
be used. Here, the control circuit is switched off via a
safety relay as soon as the EMERGENCY STOP button is
actuated. If the switch-off is performed, for instance,
from a „safe controller" with semiconductor outputs,
the residual voltage must be < 5V DC. Interruptions
≤ 3 ms are fi ltered.
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.

„safe controller" with semiconductor outputs, the re-

Motor overloa protection
All safety-relevant functions are implemented by the hy-
brid motor starter, without external infl uences. 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 mu t be increa e
by the value of the brake (nominal brake current).

Replacing fu e
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 fl ash and L or R light up).
