NOTE:

One or more non-contact

sensors shall be located where the
risk of entrapment or obstruction
exists at either the opening or
closing direction. Care shall be
exercised to reduce the risk of
nuisance tripping, such as when a
vehicle, trips the sensor while the
gate is still moving.

OVERVIEW OF TYPICAL INSTALLATION

INTRODUCTION

Identify your installation type (refer to the Appendix in the back of the manual for more information). All the illustrations on the following pages
