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
405DC-EC Operator in production and contains the
latest information available. The Model 405DC-EC uses
our Standard Duty Electric Clutch. This operator is used
for powering single sliding or bi-parting doors. The parts
pages have been prepared so you can easily determine
the parts contained in your operator.
C. APPLICATION:
The Model 405DC-EC electric
operator offers security as well as the quiet, smooth,
and precise movement of the door(s). The ramp-up
and ramp-down speed functionality helps to control the
overall speed of the door in the fi nal seconds of the
opening and closing cycles. Furthermore, in the event
of power failure, the electric clutch shall disconnect
the doors from the drive train, allowing the doors to
be operated manually. To prevent manual operation a
magnetic lock with a battery backup can be added to the
system.
D. DESCRIPTION:
(1) GENERAL: The Model 405DC-EC operator consists
of a permanent magnet DC motor (1/2 or 1 H.P.), a right
angle gear reducer, an adjustable electric clutch, and a
fully automatic rotary limit switch all assembled into a
complete power drive unit assembly.
(2) TRACK HARDWARE: The 405DC-MC operator is
designed to work with Crown Industrial’s #25 enclosed
Box Track constructed of #9 Ga. steel with 5/8" round
cold steel bar runways. The track is rigidly fi xed to the
supporting structure by direct attachment through the
use of steel brackets. The load of the entire door(s) is
carried on rugged heavy duty Crown #25 four wheel ball
bearing trucks. These trucks are driven by roller chain
that operates inside the #25 Box Track. Any chain slack
that accumulates over time can be taken up by Crown’s
Chain Tensioner assembly that is directly integrated with
the roller drive chain. In addition, for openings over 8’-0"
wide, sag rollers are furnished to prevent chain sagging.
Also included as an end idler assembly for single sliding
applications and a center idler assembly for bi-parting
applications.
(3) DC SPEED CONTROLLER: Another feature of
the Model 405DC-EC electric slide door operator is
its adjustable DC speed controller. This controller
converts single phase AC line power to regulated DC
for adjustable speed control of the permanent magnet
DC motor. This allows the operator’s acceleration,
deceleration, run speed, and creep speed at the ends
of each the opening and closing cycles to be fi eld
adjustable. By having control over these four features,
the durability and dependability of the operator and
hardware improves dramatically.
Features:
(a) Adjustable operating speed: 45 ft/min. or 60 ft./min.
(Dependent on Application and Opening Width).
(b) Adjustable creep speed.
(c) Adjustable Acceleration.
(d) Adjustable Deceleration.
(e) Electric Clutch.
2. INSTALLATION AND OPERATION
A. GENERAL
The Crown Industrial 405DC-MC Electric Door Operator
is rugged, well designed, and dependable. To ensure
correct installation and proper operation of the operator
and associated hardware, the following instructions are
given:
(1) SHIPMENT CHECK: To insure that all equipment
is complete, check the components received with
the material specifi cations sheets included with the
installation packet supplied with the door.
(2) REVIEW THE INSTALLATION DRAWINGS:
The installation drawings show the layout of the
door(s), template drilling for the door(s) and wall,
hardware layouts, and general terms used to describe
components. Review the drawings to familiarize yourself
with the equipment. To determine the handing of a single
slide door operator for mounting purposes, stand on the
door side of the wall, facing through the door opening. If
the door slides to your right, it is a right-hand slide door,
if it slides to the left, it is a left hand slide door
(Refer to Figure 1).
Mount operator and
sliding door hardware
accordingly.
