Manual (remote acknowledgement 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
briefly. If a negative edge is not identified 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.
Feedback
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.
Parameterization –
Nominal current setting
Note: This function is only possible if the device is not
activated and there is no defect at the device.
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. Press the set / reset button for more than 6s to
change to the „Parameterization" mode – the green
PWR LED flashes once.
Note: In Parameterization mode, the LEDs are
switched off every 2s for 0.3s to distinguish this mode
from other operating modes.
4. Set the nominal current of the drive using the 240°
potentiometer. The nominal current is specified 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.

Note: If the motor current is above 45A, the block

6. Application examples

Safety door (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
