Introduction

The Crown Industrial No. 1295 Electric Gate Operator is supplied with the internal wiring of the

electrical components completed at the factory. Terminal strip provision is supplied for site wiring

of the operator to external power supply and control system. The factory wiring provides for ease

in site applying a number of different control systems to the operator by variations in terminal

connections and bridging. The purpose of this booklet is to provide wiring diagrams and

instructions for the most popular of the Gate Operator Control Systems. It is to be used in

connection with the Installation Manual (G-991) supplied with each operator.

General Notes

Wiring diagrams have been prepared to illustrate conditions with the gate in the fully closed

position. On the wiring diagrams of the Operator Assemblies i.e. pages 4, 5, 6 and 7 heavy

weight lines have been used to denote the internal power wiring and lighter weight lines for

internal control wiring. On the diagrams of "Control Systems" i.e. pages 8,9, 10 and 11 heavy

weight lines have been used to show site Wiring and lighter weight lines to denote factory wiring.

In the control diagrams, control circuits transformers are shown. (Control circuit transformers are

not provided With operators intended for use on 115 volt power supplies.) Terminal connection

numbers for control wiring are always retained.

See general installation Instructions manual (G-991) for establishing proper direction of gate travel.
