Gating restart

A gating restart is necessary in the following cases:

• The protective field is interrupted, but at least one synchronization beam is not occupied.

and

• The CS switching signal is activated (operating mode 4 or 5).

• The CS switching signal and the TH timer hold signal are activated (operating mode 1 or 6).

WARNING

Unauthorized gating restart may result in serious injury!

Ä

An instructed person must watch the event carefully.

Ä

Make certain that the danger zone can be viewed from the reset button and that the entire
process can be observed by the instructed person.

Ä

Before and during the gating restart, ensure that there are no people in the danger zone.

Performing gating restart

Ä

If the safety sensor responds with an error message, perform an error reset first (see chapter 12 "Trou-
bleshooting"
).

Ä

Press and release the reset button within 0.15 s to 4 s.

The OSSDs of the safety sensor are switched on.

NOTICE

If, after the button is pressed for the second time, a valid gating state is present (CS switching
signal is applied, protective field interrupted), the initiated gating sequence is continued. The ML
signal output alternately delivers 0 V and 24 V until the OSSDs are switched on again.
