SITE PREPARATIONS
It is imperative that the wall or mounting surface provide adequate support for the operator. The safety and wear
of the operator will be adversely affected if any of the following requirements are not met.
a) Mounting surface to be rigid to prevent play between operator and door shaft.
b) Provide a level base.
c) Permit the operator to be fastened securely and with the drive shaft parallel to the door shaft.
IMPORTANT SAFETY NOTES
INSTALLATION INSTRUCTIONS
TYPICAL SHAFT INSTALLATION
1. Slide the shaft collar supplied over the door shaft to
desired position and secure in place.
2. Slide the operator on the door shaft until it contacts the
shaft collar. Insert the 4-1/2” key supplied into the operator
and the door shaft.

SENSING EDGES
All types of sensing edges with an isolated normally open
(N.O.) output are compatible with your operator. This
includes pneumatic and electric edges. If your door does
not have a bottom sensing edge and you wish to purchase
one, contact the supplier of your operator.
If not pre-installed by the door manufacturer, mount the
sensing edge on the door according to the instructions
provided with the edge. The sensing edge may be
electrically connected by either coiled cord or take-up reel.
Refer to the steps below.
Important Notes:
a) Proceed with Limit Switch Adjustments before making
any sensing edge wiring connections to operator as
described below.
b) Electrician must hardwire the junction box to the
operator electrical box in accordance with local codes.
ENTRAPMENT PROTECTION ACCESSORIES (OPTIONAL)
IT IS STRONGLY RECOMMENDED THAT A
SENSING EDGE OR OTHER ENTRAPMENT
PROTECTION DEVICE BE USED IN
CONJUNCTION WITH THIS OPERATOR.

THE LIMIT SWITCHES WILL STOP THE DOOR AT EACH
END OF TRAVEL. ADDITIONAL LIMIT SWITCHES CAN
BE USED FOR CONTROL OF OTHER AUTOMATIC
FUNCTIONS.
NOTE: Before starting adjustment of the limit switches,
loosen or tighten (if necessary) the lock nut in order to
obtain a convenient adjustment tightness of the cam
wheels. After finishing the adjustments, make sure that the
lock nut is sufficiently tight 1 NM (8”LBS) to retain the cam
wheels securely during operation.
When door is in the fully open position, the green cam
wheel (Open) will be turned into contact with its
corresponding switch. In the same way, just before the
door is in the closed position, the black cam wheel (Closed)
will activate its switch.
COARSE ADJUSTMENT
The coarse adjustment of the limit switches can be done by
inserting a rod or a screw driver into one of the adjustment
holes in the cam wheels and by turning each cam wheel
with the rod or screw driver.
FINE ADJUSTMENT
Fine adjustment can be done by screwing the adjustment
screw (supplied) against the cam shaft thread inside each
cam wheel. The screw must be changed from one
adjustment hole into the other for turning the cam wheel in
the opposite direction.
WIRING:
For wiring of your sensing device to the operator,
refer to the wiring diagram supplied with your
operator. See field connection terminals identified as
Sensing Device or Safety Edge.
TAKE-UP REEL: Take-up reel should be installed
12" above the top of the door.
COIL CORD: Connect operator end of coil cord to
junction box (not supplied) fastened to the wall
approximately halfway up the door opening.

CONTROL WIRING
Standard C2 Wiring
Standard operators are shipped from the factory set
for C2 wiring, which requires momentary contact to
open, constant pressure to close, stop on reverse.
B2 Wiring Option
Dip switch selectable, momentary contact to open,
close and stop. Entrapment protection device must
be included.
LOCATING THE CONTROL STATION
All operators are supplied with a three button station (OPEN/CLOSE/STOP) incorporated into the wall mounted
starter. Mount the wall mounted starter where the door is visible, but not directly underneath the door, operator, or
mounting hardware.

A REVERSING EDGE
MUST BE INSTALLED ON THE BOTTOM OF THE
DOOR.
FAILURE TO INSTALL A REVERSING EDGE
UNDER THESE CIRCUMSTANCES MAY RESULT IN
SERIOUS INJURY OR DEATH TO PERSONS
TRAPPED BENEATH THE DOOR.

DETERMINE WIRING TYPE
Refer to the wiring diagram located on the inside cover the electrical box to determine the type of control wiring.
SPECIAL CONTROL WIRINGWIRING TYPES
If your operator was shipped from the factory with
non-standard control wiring or with optional
accessories that require additional instructions, refer
to the wiring diagram(s) indicated in the special
control wiring data box. When a replacement wiring
diagram is present, wiring diagrams in this manual
will not apply. Refer only to the replacement wiring
diagram for all connections.
IMPORTANT NOTE: If your wiring diagram is
missing, or you are unsure of the wiring type for
your operator, contact the customer service
department @ 1-800-528-2806.

CONTROL WIRING (con’t)
Radio Controls
All radio controls must have dry contact relay
outputs. Power for radio is to be supplied by an
outside source. Do not take power from the
components inside the electrical enclosure.
Additional Access Control Equipment
Locate any additional access control equipment as desired (but so that the door will be in clear sight of the person
operating the equipment), and connect to the terminal block in the electrical enclosure as shown on the FIELD
WIRING CONNECTIONS diagram. Any control with a normally (N.O.) isolated output contact may be connected
in parallel with the OPEN button. More than one device may be connected in this manner. Use 16 gauge wire or
larger for all controls. DO NOT USE THE CONTROL CIRCUIT TRANSFORMER (24VAC) IN THE OPERATOR
TO POWER ANY ACCESS CONTROL EQUIPMENT OTHER THAN A STANDARD RESIDENTIAL TYPE RADIO
RECEIVER.
Manual Release Brake
The operator is equipped with a internal interlock switch mounted to the brake assembly. When the brake is
manually dis-engaged the control circuit will be disabled, thereby preventing electrical operation of the door from
the control devices.
WARNING
CAUTION
WARNING
WARNING
DO NOT USE RADIO CONTROLS WITH YOUR
OPERATOR UNLESS YOU HAVE INSTALLED
SOME TYPE OF ENTRAPMENT PROTECTION
DEVICE. THE USE OF RADIO CONTROLS
PRESENTS POTENTIAL HAZARDS DUE TO THE
USER’S ABILITY TO OPEN OR CLOSE THE
DOOR WHEN OUT OF SIGHT OF THE DOOR.
NOTICE:
This equipment has been tested and found to comply with the limits for a Class A digital
device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide
reasonable protection against harmful interference when the equipment is operated in a
commercial environment. This equipment generates, uses, and can radiate radio frequency
energy and, if not installed and used in accordance with the instruction manual, may cause
harmful interference to radio communications. Operation of this equipment in a residential
area is likely to cause harmful interference, in which case the user will be required to correct
the interference at his own expense.
The operator has been pre-wired to accept
connection of a reversing edge device. Connect the
normally open contacts to terminals 5 and 6 located
on the LMPLC board. An auxiliary limit switch (yellow)
will deactivate the safety device during the last few
inches of the door’s downward travel.

WARNING
IF CONTROL STATION CANNOT BE INSTALLED WHERE

REVERSING EDGE UNDER THESE CIRCUMSTANCES
MAY RESULT IN SERIOUS PERSONAL INJURY OR
DEATH TO PERSONS TRAPPED BENEATH THE DOOR.

Auxiliary Contacts
Three auxiliary normally open dry contacts will be
available. They will accept a max. of 15 amps, 120V
AC/DC. Terminal Block J2 located on the LMPLC
board is used to access these contacts.
1) Terminal J2-17 and J2-18 will close when the door
is fully closed.
2) Terminal J2-19 and J2-20 will close when the door
is stopped at any position other than fully closed.
3) Terminal J2-21 and J2-22 will close when the door
is in motion.
Single button control is available as an optional
device and is wired to terminals J2-11 and J2-12 on
the LMPLC board.
POWER WIRING CONNECTIONS
1. Connect power wires to the J1 terminal block
located on the Printed Circuit Board (shown below).
(See wiring diagram page 11, 13, and 15)
CONTROL WIRING CONNECTIONS
1. Connect control wires to the J2 terminal block
located on the Printed Circuit Board (shown below).
(See wiring diagram page 11, 13 and 15)
2. Apply power to the operator. Press OPEN push
button and observe direction of door travel and then
Press the STOP button.
If door did not move in the correct direction, check for
improper wiring at the control station or between
operator and control station.(See page 19)
1. Connect earth ground to chassis ground screw in the
electrical box enclosure marked with the label shown
below.
2. Use same conduit entry into the electrical box as the
power wiring.
