MODEL MO OPERATOR APPLICATIONS:

MO operators are intended for commercial and industrial
use to raise or lower rolling steel or sectional overhead
doors by chain coupling to the door shaft. MO operators
are suitable where all or part of the door remains in a
vertical position when fully open such as doors with at
least 18 inches of lift clearance or full vertical lift doors.
MO operators may also be used with roll up service doors
and grills when specified on order from factory.

An MO operator DOES NOT LOCK THE DOOR IN
ITS CLOSED POSITION. However, because the cross­header shaft is prevented by the operator from turning, the
torsion springs provide no assistance in lifting the door
should an attempt be made to raise it manually.

MO operators are used in the following applications:

- Continuous Duty, Medium and Heavy Duty Cycle

Commercial installations.

- Indoor Use Only

- Doors with a maximum area of 560 square feet

(2zHP) - maximum area slightly higher for lighter
doors - consult factory

- Use with foam/pneumatic reversing door edge or

photoelectric device - REQUIRED where the 3­button station is out of sight of the door, or any other
automatic, remote or manual control is used to
activate the door

STANDARD FEATURES:

Limit Switches: Driven limit switches, easily adjusted over

a wide range. The motor may be removed without affecting
the limit switch adjustments

Manual Release: Permits manual operation of the door in

the event of a power failure. The Model MO is equipped with
a chain hoist to aid in manual operation.

Control Circuit: Standard three button open, close and stop.

24 Volts AC.

Connections For Auxiliary Entrapment Protection
Devices:

components or a photoelectric beam (across the opening)
device.

Constant Contact To Close: Feature can be activated by

simply moving a wire on the terminal strip.

Momentary Contact To Close: Standard operation.

Use with foam or pneumatic reversing door edge

OPTIONAL FEATURES:

Digital Radio Controls: Open, Close and Stop

operation. Radio units are available to control up to 27
doors from one transmitter

Digital Timer to Close: Adjustable from 0 to 17

minutes in one second intervals.

Keyless Entry System: Connection terminals provided

for hard wired keyless entry system. Optional radio receiver
will allow operation of a wireless keyless system.

PREPARATION

WARNING

ELECTRIC DOOR OPENERS ARE DESIGNED FOR

DOORS IN GOOD WORKING CONDITION,

PROPERLY COUNTERBALANCED AND PROPERLY

ADJUSTED IN ACCORDANCE WITH THE DOOR

MANUFACTURER'S INSTALLATION

INSTRUCTIONS.

Before starting the installation of the operator, the door must be in good
working condition and properly counterbalanced. Inspect the door and
door guides for loose or missing hardware. Test the door manually for
balance and ease of operation. Lubricate door hinges and rollers. If
necessary, employ a qualified technician to adjust the springs for proper
counterbalance of the door.

Stops should be installed at the top end of each track to prevent the
possibility of the door rollers moving beyond the ends of the track.

If the cross header shaft is made from hollow tubing rather than solid
rod, it is recommended that it be plugged with a short length of solid bar
for a more secure installation of the shaft sprocket or flange coupler.
Before removing the operator powerhead from the shipping carton,

4

inspect the nameplate on the cover of the operator control
box to verify that it is the correct model for the intended
application and that the voltage and phase are in accordance
with electrical power provided at the job site.

Warning: Rope off the area to keep personnel and
vehicles clear of the door and floor space in the vicinity
of the operator during the installation.

WARNING

SPRINGS ARE SUBJECT TO VERY HIGH

FORCES AT ALL TIMES AND

ADJUSTMENTS MUST BE MADE ONLY

BY A QUALIFIED PROFESSIONAL DOOR

IMPORTANT INSTALLATION NOTES

TO REDUCE THE RISK OF SEVERE INJURY
OR DEATH: READ AND FOLLOW ALL

INSTALLATION INSTRUCTIONS!

• Install only on a properly balanced garage door.
An improperly balanced door could cause severe
injury. Have a qualified service person make repairs
to cables, spring assemblies and other hardware
before installing the opener.

• Remove all ropes and remove or make
inoperative all locks (unless mechanically and/or
electrically interlocked to the power unit) that are
connected to the garage door before installing the
opener.

• Lightweight doors (fiberglass, aluminum etc.)
must be reinforced to avoid door damage. Check the
door manufacturer’s instruction manual for a bracing
procedure or the availability of a Reinforcement Kit.

• The MO Series Operator is a Commercial
Vehicular Door Operator and as such is NOT
recommended for pedestrian traffic. In installations
where it is known that pedestrians will be nearby
ensure a pedestrian door is available for entrance and
exit to the building. In addition YOU MUST install
an auxiliary entrapment protection device (reversing
door edge or photoelectric beam device) as part of the
complete operator system.

• Connect an auxiliary entrapment protection
device (reversing edge or photoelectric device across
the door opening). A device of this type is

STRONGLY ADVISED FOR ALL commercial
operator installations. An auxiliary entrapment
protection device is REQUIRED when the three
button control station is out of sight of the door or
any other automatic or manual control is used.

• Install the opener at least 8 feet or more above
the floor.

• Do not connect the opener to the source of
power until instructed to do so.

• Locate the control station:

a) within sight of the door and;

b) at a minimum height of five feet
above the floor and;

c) away from all moving parts of the
door.

• Do not overtighten the clutch adjustment
(where provided) to compensate for a poorly
working door.

• Securely attach any WARNING signs or
placards to either the door or above the control
station as directed (see page 15).

• After installing the opener, all control features
must be tested for proper operation (see page 19).

WARNING

INSTALLATION INSTRUCTIONS

SPRINGS, PULLEYS, CABLES AND MOUNTING HARDWARE USED TO

BALANCE YOUR GARAGE DOOR ARE UNDER EXTREME TENSION AT ALL

TIMES AND CAN CAUSE SEVERE INJURY OR DEATH IF DISTURBED.

DO NOT ATTEMPT ADJUSTMENT.

MOUNTING THE OPERATOR

WHEN PREPARING THE MOUNTING SURFACE
ENSURE THE OPERATOR WILL BE RIGID AND
SECURE WHEN INSTALLED, THE MOUNTING
SURFACE WILL PROVIDE A LEVEL BASE, AND THE
OPERATOR’S DRIVE SHAFT WILL BE PARALLEL
WITH THE DOOR SHAFT. FAILURE TO MEET THESE
CONDITIONS WILL RESULT IN AN OVERALL UNSAFE
DOOR OPERATION AND PREMATURE FAILURE OF
THE DOOR AND DOOR OPERATOR.

1. Figures 2 and 3, page 6 illustrate several positions suitable
for mounting the operator; right hand or left hand wall
mount or horizontal (shelf) mount to the torsion shaft. For
sectional doors, the MO operator must be wall mounted.
For rolling steel doors the operator may be wall mounted or
hood mounted by using an optional hood mounting bracket,
[14]. A wall mounting plate [13] is also available from the
factory (see Figure 1). The mounting plate/bracket
provides for chain tension adjustment as well as aiding
installation.

NOTE: THE OPERATOR DRIVE SPROCKET MAY

BE INSTALLED ON EITHER SIDE OF THE GEAR
REDUCER. SELECTION DEPENDS ON WHICH SIDE
OF THE DOOR THE OPERATOR IS MOUNTED ON.

2. Determine which side of the door the operator will be
located on. Fasten the sprockets [5] and [12] and the keys
[4] on the chosen side of the torsion shaft of the door and
on the corresponding end of the output shaft of the operator.
Tighten the set screws enough to prevent the sprockets from
sliding off the shaft. If the door shaft lacks a keyway you
will need to drill and pin the sprocket in accordance with
Step 6 (tightening the set screws is sufficient for this step).
The sprockets should be kept as close as possible to the
bearings. Fasten the wall mounting plate or the mounting
bracket (as applicable and if available) to the operator gear
box flange. Temporarily suspend the operator in its
mounting position and such that the distance between the
door shaft and the operator’s output shaft is between 12”
and 15”. See Figure 5 for wall mount and Figure 6 for
hood mount illustration. The distance between the shafts
may be greater if the mounting conditions prohibit
installation as suggested.

4. With the chain tight and straight and the operator’s output
shaft parallel with the door’s torsion shaft, trace the
mounting slots (holes) on the mounting surface then lower
the operator to the floor. The MO operator gear box
mounting hole pattern is shown in Figure 4.

5. The operator should be installed using 1/2” bolts through
the wall. If the building’s construction will not allow the
usage of through bolts then use lag bolts and shields (or the
equivalent type fasteners). Mount the operator, slipping the
drive chain on before bolting the operator to the mounting
surface but do not completely tighten the bolts at this time.

6. Re-align the door shaft and operator drive shaft sprockets
and connecting drive chain. Secure the sprockets in place
with their set screws. If no keyway exists in the door shaft,
drill a 5/16” through the door sprocket and door shaft with
the sprocket in its aligned position. Insert the 5/16” roller
pin [2] through the sprocket and shaft to secure the sprocket
in place. See Figure 7.

7. Adjust the drive chain tension such that there is no more
than 1/4” slack when the chain is depressed between the
sprockets. See Figure 8. The preferred mounting is with
the motor end up and the operator below the door shaft.
This results in better clearance for the hand chain and
disconnect chain.

8. Attach sash chain, item 10, with cotter pin, item 9. See
Figure 9, next page.

Figure 4

3. Connect the two drive sprockets [5 and 12] with the drive
chain [6] and connecting link [7], shortening the chain to
the proper length if necessary. To shorten the chain use a
chain tool or drive out the appropriate rivets with a punch.

CHAIN HOIST INSTALLATION

1. Refer to Figure 10 to install the chain hoist. Pass the

hand chain, item 13 over the chain pocket wheel and
through the chain guide holes on the operator clutch
shaft (opposite end from the large pulley). Fasten the
ends of the chain together (to make one continuous loop)
by opening and re-closing one link using two pairs of
pliers. If the chain is too long, shorten it to the desired
length by removing links.

2. After attaching sash chain, item 10, with tension spring,

(See Figure 9), pull the sash chain to engage the hand
chain. This will actuate the interlock switch and
disengage the solenoid brake.

3. Use lag screws to attach the disconnect bracket, item 11,

vertically in line with the sash chain about four feet off
the floor. See Figure 11.

BEFORE PROCEEDING WITH THE
OPERATOR INSTALLATION AND
SETTINGS, MAKE A FINAL CHECK FOR
TIGHTNESS OF ALL MOUNTING
HARDWARE AND SET SCREWS.

INSTALLATION INSTRUCTIONS

WARNING

TO AVOID RISK OF ENTRAPMENT AND

POSSIBLE DAMAGE TO THE DOOR AND

OPERATOR THE LIMITS MUST BE ADJUSTED

BEFORE APPLYING POWER TO THE

OPERATOR.

SETTING THE LIMIT SWITCHES

1) With the cover open on the electrical enclosure, reference

Figure 12 below. There are four (4) switches (A, B, C, and D)
mounted to the ‘V’ bracket (H). The limit switches are mounted
in a fixed position to the underside of the ‘V’ bracket; with the
Close Limit switch (B) on the right and the Open Limit switch (D)
on the left. The Reverse Cutout switch (A) and the Single Button
Selector switch (C, also could be Timer Engage switch depending
on the model) are mounted to the top side of the ‘V’ bracket as
shown. The switches are activated by the two limit nuts (E & G)
on the threaded shaft which move laterally along the shaft as the
operator opens and closes the door. When a limit nut nears the
end of the shaft it activates a set of switches, upper switch first
then the lower fixed limit switch.

2) Depress the Limit Nut Retention Plate (F) so it disengages

from the slots in the limit nuts and move the Limit nuts to the
center of the threaded shaft.

10

3) Manually raise the door to a nearly open position.

4) Depress the limit nut retaining bracket (F) so it disengages
from the slots in the limit nuts. Turn the OPEN limit nut (E) on
the shaft until it engages both the Single Button Selector switch
(C) and the Open Limit Switch (D). You will need to listen for
two audible clicks. Release the retaining bracket and be sure
that it engages in slots of both limit nuts.

5) Manually lower the door to the fully closed position and
repeat Step #3 with the Close Limit nut (G) and Reverse Cutout
switch (A) and the Close Limit switch (B).

6) Manually move the door to a half open position. With the
door in a mid position there will be time to stop the door if
something or someone were in the door path when initially
starting the door.

7) A final limit adjustment will be necessary after the
connection of the power supply in order to ensure the door stops
at the proper Open and Close positions.

8) Adjustment of the Reverse Cutout switch (A) or Single
Button Selector switch (C) is done at the factory and should not
be needed in the field. Moving the Reverse Cutout switch
closer to the center of the box will increase the point where the
reversing feature cuts out (to allow for irregularity in the floor,
etc.). The reverse cutout point is factory adjusted to approx. 4
inches off the floor.

ELECTRICAL WIRING INSTRUCTIONS

WARNING

TO PREVENT THE RISK OF PERSONAL INJURY
OR DEATH :

• DISCONNECT POWER AT THE FUSE BOX
BEFORE PROCEEDING.

• ELECTRICAL CONNECTIONS MUST BE MADE
BY A QUALIFIED INDIVIDUAL.

• OBSERVE LOCAL ELECTRICAL CODES WHEN
WIRING THE OPERATOR.

WARNING: Allstar MO operators have been
designed and constructed for use with voltages
from 115 Volts AC to 480 Volts AC, in single or
three phase. Check the operator nameplate label on
the control box cover for the proper voltage and
phase. The application of an improper input voltage
or phase will result in catastrophic failure to the
internal electrical components.

Observe local electrical codes when wiring the operator.

When hard wiring, observe state and local electrical codes. A
wiring diagram is attached to the inside of the control box cover.
Connect the appropriate voltage and phase power leads to the
appropriate terminals as per the wiring diagram and connect a
ground wire to the grounding screw. On three phase units,
incorrect phasing of the power supply will cause the motor to
rotate in the wrong direction (open when CLOSE button is pushed
and vice versa). To correct this, interchange any two of the
incoming three phase conductors.

The wiring diagram attached inside the cover of the control box
details all of the field wiring terminal connections for the operator.
Always connect the wires to the push-button controls and auxiliary
devices exactly as shown.

Warning: Control voltage of the operator is 24 volts AC,
Class 2. Do not run the power leads and control circuit wiring
in the same electrical conduit.

WARNING

WARNING

RISK OF ENTRAPMENT THAT MAY

RESULT IN SERIOUS PERSONAL INJURY OR

DEATH. DISCONNECT POWER TO THE

OPENER BEFORE AND DURING

INSTALLATION OF AN ACCESSORY

REVERSING DOOR EDGE OR

PHOTOELECTRIC DEVICE. DO NOT

RECONNECT POWER TO OPENER UNTIL

INSTRUCTED TO DO SO. ENSURE DOORWAY

IS CLEAR BEFORE STARTING TESTING OF

Note: Most MO operators are pre-wired for door reversing
edge components. To comply with code requirements, the
door reversing edge components must be installed and wired
to the operator. Refer to Figures 16 and 17 for Edge
component wiring and installation.

For operator models not equipped with reversing edge
components ONLY ONE THREE BUTTON WALL
STATION AND NO OTHER MEANS OF CONTROL may
be used to control the operator. This is to comply with safety
requirements. In this case the pushbutton station must be
located WITHIN CLEAR SIGHT OF THE DOOR adjacent
to a placard (supplied with the operator) with this wording:

WARNING

TO PREVENT ENTRAPMENT

DO NOT START DOOR DOWNWARD

UNLESS DOOR WAY IS CLEAR

Operators which are equipped with a reversing edge circuit may
have one or more additional means of control which should be
wired in accordance with the diagram supplied in the operator.
To add a second three button station, refer to Figure 17.

Number 18 gauge wire or heavier must be used for wiring
the control stations and auxiliary control devices to the
operator. Smaller gauge wire will cause operational
problems, especially when multiple push-button stations are
used or during summer months.

TO PREVENT THE RISK OF PERSONAL INJURY

AND/OR DAMAGE TO DOOR OR PROPERTY,

ONLY OPERATE DOOR CONTROL WHEN

DOOR IS IN CLEAR VIEW. IF CONTROL

STATION CANNOT BE LOCATED WHERE THE

DOOR IS VISIBLE OR IF ANY OTHER DEVICE IS

USED TO CONTROL THE DOOR AN AUXILIARY

ENTRAPMENT DEVICE (DOOR EDGE OR

PHOTOELECTRIC) MUST BE CONNECTED.

TO AVOID DAMAGE TO DOOR AND

OPERATION AND ADJUSTMENT INSTRUCTIONS

BRAKE ADJUSTMENT

The solenoid operated brake may require
occasional adjustment. Adjustment is necessary if
door tends to drift downward after reaching the open
limit. Follow the instructions below and use Figure
18 as a guide.

(1) Loosen shoe adjusting screw and bottom bracket

arm of solenoid.

(2) Move tab until drum has a slight drag.

(3) Reverse drag slightly from tab and tighten shoe

adjustment screw.

TESTING

Following installation, the operator MUST be tested and
respond correctly to all controls as specified on the wiring
diagram. KEEP personnel and equipment clear of the area
beneath the door when performing the tests. When testing the
3-button wall station, first observe that each button operates
the door in the direction indicated and that the STOP button
performs that function. With the door stopped at its full open
position, the OPEN button should be inoperative. This should
be verified and, likewise, the CLOSE button should be
inoperative with the door fully closed.

Certain operator control circuits use only a single button or a
two button control station and may be designed to function
differently than the more common three-button circuit
described above. Test the controls in accordance with the
description of operation as indicated on the wiring diagram
and on page 18, Wiring Types.

Observe the door when traveling in each direction for
smoothness of operation. Test the setting of the clutch by
restraining the door by hand. The clutch should slip. Re-check
the limit settings. The door should close tightly at the floor
without excessive impact. Likewise, it should fully clear the
door opening without the carrier striking the stops on the rail.

Allstar MO operators are equipped with a reversing edge
circuit and to conform with code need to be connected to a
pneumatic edge or foam edge door components. To test it for
proper reversal, place an object beneath the leading edge of the
door. The door should instantly reverse when it comes into
contact with the object provided the height of the object
exceeds the cut out point built into the close limit switch
(approximately four inches).

Figure 18

CAUTION

DO NOT STAND UNDER DOOR

TO TEST REVERSING EDGE

USE A CORRUGATED BOX

OR OTHER SIMILAR OBJECT

If the operator is equipped with other means of control, such as
additional 3 button stations or radio controls, each of these
should be tested separately for proper operation.

To test the manual disconnect first move the door to the fully
closed position. Then disconnect the power to the operator.
Manual door operation mode should engage when the release
chain is pulled. The door can then be manually opened or closed
by physically moving the door or using the hoist chain. If it is
difficult to engage and/or the jackshaft to doorshaft chain
appears to be under compression, reset the CLOSE limit slightly
to reduce the door travel in the close direction.

WARNING

ALWAYS DISCONNECT POWER TO

THE OPERATOR BEFORE SERVICING,

CONNECTING ACCESSORY DEVICES

OR MAKING ADJUSTMENTS.

MAINTENANCE

20

Normally, very little maintenance is required. A monthly visual
inspection must be made for loose or missing hardware and for
excessive slack in the V-Belt and jackshaft chain. The brake is
adjusted at the factory and will need periodic adjustment for wear.
When adjustment becomes necessary see Figure 18 on page 19
for the adjustment procedure.

Test the reversing edge circuit or components (where applicable)
at least once a month by permitting the door to contact an
obstruction while closing.

Periodic inspection of gear box oil level should be made by
removing oil level plug. If oil level is below this plug, add Esso
Gear Oil XP90 or Mobilelube “C” SAE 140 or equivalent to bring
to proper level.

CAUTION

DO NOT STAND UNDER DOOR TO TEST

REVERSING

EDGE - USE A CORRUGATED BOX

OR OTHER SIMILAR OBJECT

Lubrication of the operator is not required. It is important, for
trouble free service from the operator, that the door be kept
free from binding, properly counter balanced and periodically
lubricated. An annual inspection of the door by a qualified

overhead door professional is recommended.

Warning: Repairs and adjustments to the door and
operator should be performed only by someone qualified
to service commercial overhead doors and operators.

If door overrides up limit, check down button and circuit. If door
overrides down limit, check open button and circuit.

Replace chain, check limit screw for rotating.

* Door must be in good operating condition.
An electrical door operator cannot move a garage door that is in poor condition. The door must operate freely in the track, with no binding or obstructions, and must
be well balanced. Check the spring balance of your door by bringing the door to a half-open position and leaving it there. If the door stays in that position, it is well
balanced. If it moves more than a few inches the springs possibly need adjustment. Call a qualified door service company.
