Control Terminal: External
terminals provide quick, convenient connections for radio
controls.
Positive Locking Mechanical Brake System:
electric garage door opener Efficient
self-locking mechanical reduction system that functions as a
holding brake.
Friction Clutch:
Adjustable friction clutch helps protect
against major damage to door and operator should the door
meet an obstruction.
Bearings:
Industrial ball bearings on a 1" output
shaft; heavy-duty, oil filled iron bearings on reduction
shafts.
Control Circuit:
24V NEC Class 2.
Construction:
NEMA 1 type electrical box, heavy-duty
11-gauge steel frame with durable backed-on powder coat
finish, all reduction sprockets drilled and pinned to
shafts.
Pushbutton Station:
3-button station for OPEN/CLOSE/STOP
functions is standard for all operators. Controls with one,
two and three buttons are available.
Standard on
the Garage2Home Logic Control (L):
Maintenance Alert System: This important feature
provides an accurate method for tracking door use and
establishing safe and effective maintenance programs for the
door and the operator. The Maintenance Alert System features
an internal programmable cycle timer that actually counts
each time the door cycles. This system is easily preset by
the installer for the particular door and application. Once
the preset number is reached, an indicator light on the
3-button station flashes to signal that it is time for
routine door and operator maintenance.
Maximum Run
Timer: This standard
feature on the Logic Control Board (L) is designed to
protect against damage to the door and electric garage door
opener . Simply set
the system to auto learn the door's standard cycle time. Any
time a moving door takes 10 seconds more than its programmed
standard cycle time, the door will automatically stop. The
maximum run time for the default is 90 seconds.
Delay-on-Reverse Circuit.
Programmable Mid-StopControl
Accessories and Options:CPS®
Commercial Protector System: (Recommended) An
inexpensive "non-contact" photo safety sensor designed to
sense an obstruction and signal the door operator to reverse
to open.
Sensing Edge:
(Recommended) Designed to sense an
obstruction and signal door operator to stop or reverse as
desired. Either an electric or pneumatic sensing device can
be added to bottom edge of door.
Brake:
Heavy-duty solenoid actuated brake
standard on 3/4 HP and higher
Emergency Egress
Device: Attractive
faceplate mounts flush to the wall and contains handle to
disconnect operator from grille, thereby allowing grille to
be opened manually or by spring tension.
Radio Control:
Universal transmitters and receivers are
available to signal the operator to open and/or close door.
Rolling Door Interlock Switch:
Interlock switch disables the operator
control circuit when a manual door lock is engaged
preventing damage to the door and electric garage door
opener .
Available
Plug-In Option Boards for the Solid State Logic Control
Board (L):CPS II

contains a Timer-to-Close function.
Timer-to-Close
Option: Part of the CPS II
board. It provides the ability to close the door at a
programmable time from 5 seconds up to 1 hour. Combined with

Option Board: Features
both normally-open and normally-closed contacts that actuate
when unit is powered down. Can be used to signal security
systems, operate heaters, warning devices or other ancillary
devices (5V to 240V).
