1.5.7 Manual and automatic resets
An external pushbutton can be used to send an manual reset signal in order
to acknowledge error conditions. This button can be connected between the
RES – MAN terminals or between the A1 (24 V DC) – MAN terminals.
Meanwhile, automatic resets for acknowledging error conditions can be
implemented by establishing an electrical connection between the RES – AUT
terminals.
1.5.8 Feedback output
As soon as the electrical motor starter detects a fault, the feedback relay will
be energized, i.e., the N/O contact (contact 95/98) will be closed or N/C con-
tact 95/96 will be opened. This behavior is the same as that of a motor-pro-
tective circuit breaker or an overload relay.
This feedback signal is used for signaling purposes only and is not part of the
safety circuit. Because of this, it is not included in safety considerations.
DANGER
Please note that automatic restarts can result in bodily injury
and property damage!
The risk of an automatic restart exists when using the “auto-
matic reset“ operating mode (electrical connection between
RES – AUT terminals). This automatic restart will occur after the
cool-down period elapses (20 minutes).
DANGER
Do not use the automatic restart function in explosion protec-
tion applications!
