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) 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 HOLLOW 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 is laying
against the shaft collar. Insert the 4-1/2” key supplied into
the operator and the door shaft.

4. Slide the second shaft collar on the door shaft until it is
laying against the operator and secure in place, this will hold
the 4-1/2” key in place.

5. Secure mounting bracket to wall (pad out as necessary).

NOTE: For additional help refer to the illustrations below.

OPTIONAL THOUGH-SHAFT INSTALLATION:

1. Slide the through shaft supplied into the operator to
desired position. Insert the 4-1/2” key supplied into the
operator and the door shaft.

2. Install a shaft collar onto each end of the through shaft
until they are laying against the operator and secure in
place, this will hold the 4-1/2” key in place.

3. Install the 12 tooth sprocket onto the though shaft with
the 1/1/2” key supplied.

4. Install the door sprocket supplied to the door shaft and
connect the operator to the door with chain supplied.

5. Secure mounting bracket to wall (pad out as necessary).

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 oper-

ator 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.

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.

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 stating 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 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.

DISCONNECT POWER AT THE FUSE BOX BEFORE
PROCEEDING.

OPERATOR MUST BE PROPERLY GROUNDED AND
CONNECTED IN ACCORDANCE WITH LOCAL ELEC­TRICAL CODES. NOTE: THE OPERATOR SHOULD
BE ON A SEPARATE FUSED LINE OF ADEQUATE
CAPACITY.

ALL ELECTRICAL CONNECTIONS MUST BE MADE
BY A QUALIFIED INDIVIDUAL.

WARNING

TO AVOID DAMAGE TO DOOR AND OPERATOR,
MAKE ALL DOOR LOCKS INOPERATIVE. SECURE
LOCK(S) IN "OPEN" POSITION.

IF THE DOOR LOCK NEEDS TO REMAIN FUNCTION­AL, INSTALL AN INTERLOCK SWITCH.

1. Be sure that the power supply is of the correct volt­age, phase, frequency, and amperage to supply the
operator. Refer to the operator nameplate on the
cover.

2. Using the 7/8” dia conduit access knockout as
shown below, bring supply lines to the wall mounted
starter and connect wires to the terminals indicated on
the WIRING CONNECTIONS DIAGRAM.

DO NOT TURN POWER ON UNTIL YOU HAVE FIN­ISHED MAKING ALL POWER AND CONTROL
WIRING CONNECTIONS AND HAVE COMPLETED
THE LIMIT SWITCH ADJUSTMENT PROCEDURE.

CAUTION: THIS UNIT MUST BE PROPERLY
GROUNDED. A GROUND SCREW IS SUPPLIED IN
THE ELECTRICAL BOX FOR CONNECTION OF
THE POWER SUPPLY GROUND WIRE. FAILURE
TO PROPERLY GROUND THIS UNIT COULD
RESULT IN ELECTRIC SHOCK AND SERIOUS
INJURY.

Remove the cover from the wall mounted starter. Inside this enclosure you will find the wiring diagram(s)
for your unit. Refer to the wiring diagrams for all connections described below. If this diagram is missing,
call the number on the back of this manual. DO NOT INSTALL ANY WIRING OR ATTEMPT TO RUN THIS
OPERATOR WITHOUT CONSULTING THE WIRING DIAGRAM.

CONTROL WIRING

Standard C2 or B2 Wiring

Standard operators are shipped from the factory with
jumper set for C2 wiring, which requires constant
pressure on button to close the door. If momentary
contact on close direction is desired (B2 wiring) you
must include an entrapment protection device. See
close control jumper setting below.

Constant pressure on close (C2 wiring)

Red jumper wire was placed on terminal #2 in
electrical enclosure. The operator will require
constant pressure on close control in order to keep
door moving in the close direction.

Momentary contact on close (B2 wiring)

Move red jumper wire from terminal #2 to terminal

#3. The operator will require only momentary

contact to close the door.

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 away from the door and its hardware.

WARNING

INSTALL THE WALL MOUNTED STARTER WHERE
THE DOOR IS VISIBLE, BUT AWAY FROM THE DOOR
AND ITS HARDWARE. IF STARTER CANNOT BE
INSTALLED WHERE DOOR IS VISIBLE, OR IF ANY
DEVICE OTHER THAN THE CONTROL STATION IS
USED TO ACTIVATE THE DOOR, 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.

IMPORTANT: Mount WARNING NOTICE beside or

below the wall mounted starter.

MOUNT WARNING NOTICE

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 WIRING

WIRING TYPES

If your operator was shipped from the factory with
non-standard control wiring or with optional acces­sories that require addition 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.
