1. GENERAL INTRODUCTION
A. PURPOSE:
This Crown Installation, Operation,
Maintenance and Parts Manual has been developed to
assist you in the installation, operation and maintenance
of your electric operator and thus enable you to utilize it
to its maximum effi ciency.
B. MODELS COVERED:
The manual covers the
Model 1510 Operator in production and contains the
latest information available. The parts pages have been
prepared so that you can easily determine the parts
contained in your Electric Operator.
C. DESCRIPTION:
(1) GENERAL: The Heavy Duty Operator is built into a
compact unit consisting of an instantly reversing motor, a
precision made speed reduction mechanism with V-belt
and pulleys, a safety friction disc clutch, an emergency
release, a fully automatic double acting limit switch, a
heavy duty crank and connecting arm assembly, and
a weather resistant cover (Figure 1). The Extra Heavy
Duty Operator is similar but without the V-belt and
pulleys.
(2) MOTORS: The motor has ample reserve power to
take occasional overloads, and is furnished in 1/2, 3/4,
or 1 HP sizes for standard gates, and a 1 HP (gearhead
motor) for extra large and heavy gates. Motors are
available in single phase, however three phase current is
highly recommended for best all around performance.
(3) SHAFTS AND GEARS: Shafts and gears in the
heavy unit are mounted in long life bearings enclosed
in an oil tight housing and operate at all times in a bath
of grease (extra heavy duty units are oil fi lled). The
automatic limit switch is built on the reduction unit and
stops the gate in the desired open or closed position.
(4) CRANK AND CONNECTING ARMS: The operating
levers consist of a heavy duty crank and connecting
arms. The crank arm is driven by a safety friction disc
clutch which protects equipment in case the gate comes
in contact with an obstruction. A disconnecting device is
provided to allow manual operation.
