This button can be connected between theRES – MAN terminals or between the A1 (24 V DC) – MAN terminals.Meanwhile, automatic resets for acknowledging error conditions can beimplemented by establishing an electrical connection between the RES – AUTterminals.1.5.8 Feedback outputAs soon as the electrical motor starter detects a fault, the feedback relay willbe 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 thesafety circuit. Because of this, it is not included in safety considerations. DANGERPlease note that automatic restarts can result in bodily injuryand property damage!The risk of an automatic restart exists when using the “auto-matic reset“ operating mode (electrical connection betweenRES – AUT terminals). This automatic restart will occur after thecool-down period elapses (20 minutes). DANGERDo not use the automatic restart function in explosion protec-tion applications!
