Function; Enable Zone - Reer PI SQ F-NF Manual De Instrucciones

The fail-safe inductive sensor is a proximity device with defined behaviour under
fault conditions (PDDB) to IEC 60947-5-3.
The fail-safe sensor conforms to Performance Level e according to
EN ISO 13849-1 as well as to the requirements SIL 3 to IEC 61508 and meets
SILCL 3 to IEC 62061.
Depending on the type of installation the unit corresponds to the classification
I1C40SP2 to IEC 60947-5-2 for flush installation as well as I2C40SP2 to
IEC 60947‑5‑2 for non‑flush installation (→ 6 Installation).
The fail-safe inductive sensor has been certified by TÜVNord.

5.1 Enable zone
The outputs (OSSD) are only enabled when a damping target is present in the en-
able zone. Outside this enable zone the outputs remain switched off.
The safe switch-off distance s
The enable zone is different if damping elements which deviate from the
standard target plate in terms of material, form and size are used.
