Two different options are available for error acknowledgement:

Manual (Reset button): 

 

An acknowledgement is triggered by actuating the Reset button on the device front side. 

Manual (remote acknowledgement): 

 

A remote acknowledgment operating point can be realized by connecting a button (N/O contact) between 

the MAN and RES terminals. 

An acknowledgement is triggered if a positive edge is identified at the MAN input. If a negative edge is not 

identified after approx. 2 s, the hybrid motor starter adopts the error status again since the possibility of a 

manipulation or a defect in the acknowledgement circuit cannot be ruled out.

The RES terminal provides the voltage for a reset. 

 

In variants with the rated control supply voltage of 24 V DC, this is 24 V DC and in the case of 

230 V AC, it is a special system voltage.

If the hybrid motor starter detects an error, the feedback relay is activated, i.e. the N/O contact is closed 

or the N/C contact is opened.

The feedback serves in signaling and is not a part of the safety chain. It is thus not included in the safety 

monitoring.

Integrating a hybrid motor starter into an EMERGENCY STOP chain is pictured in Fig. 3 (page 50). 

Here, the control voltage supply is switched off via the safety relays, as soon as the EMERGENCY STOP 

button is actuated.

This switch should only be used if no more than 10,000 shutdowns can be expected over the entire 

lifespan system.

If the switch-off is performed, for instance, from a "safe controller" with semiconductor outputs, the 

residual voltage must be < 5 V DC. Interruptions ≤ 1 ms are filtered. 

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 (page 51) should be used.

In this application, the control current circuit is switched and not the control supply voltage. 

If the switch-off is performed, for instance, from a "safe controller" with semiconductor outputs, the 

residual voltage must be < 5 V DC. Interruptions ≤ 3 ms are filtered.
