MODEL AUJ & AUH OPERATOR APPLICATIONS:

Jackshaft operators are intended for commercial and
industrial use to raise or lower sectional overhead
doors by chain coupling or direct coupling to the door
shaft. Jackshaft 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. Jackshaft
operators may also be used with roll up service doors
and grills when appropriately modified at the factory
to obtain the correct speeds.

A jackhaft operator DOES NOT LOCK THE DOOR
IN ITS CLOSED POSITION. However, because the
cross-header 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.

The AU Series jackshaft operators are used in the
following applications:

- Continuous Duty, Medium Cycle Commercial

installations only

- Indoor Use Only

- Up to 24 foot high doors with a maximum area

of 480 square feet for 3/4 HP, 280 square feet
for 1/2 HP and 200 square feet for 1/3 HP ­maximum area slightly higher for lighter doors

- consult factory

- Use with foam/pneumatic reversing door edge

or photoelectric device - REQUIRED where the
3-button 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 AUH 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:

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

Use with foam or pneumatic reversing

Constant Contact To Close: Feature can be activat-

ed by simply moving a wire on the terminal strip.

Momentary Contact To Close: Standard operation.

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 or wireless keyless entry
systems.

Direct Coupling (FS or FC Mount): Must be pre-

ordered from the factory. Flange couplers direct
connect the operator output shaft and the door shaft.
Door shaft speed is 30 RPM unless otherwise
specified.

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 track 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,
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. If the operator was
ordered with the optional chain hoist, Model AUH, see that it
is so equipped. A chain hoist CANNOT be added in the field.

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

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 or a Reinforcement Kit.

• Allstar Model AUJ and AUH are
Commercial Vehicular Door Operators and as
such are 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 compete 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
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 11).

• After installing the opener, all safety
features must be tested for proper operation
(see page 16).

TIMES AND CAN CAUSE SEVERE INJURY OR DEATH IF DISTURBED.

WARNING

DO NOT ATTEMPT ADJUSTMENT.

Figure 4, page 8 illustrates several positions suitable for

mounting the operator; right hand or left hand, either wall mount
or ceiling mount and center mount with direct coupling to the
torsion shaft. Direct coupling may also be used in a side mount
installation. Operators intended for direct coupling require an
internal speed modification and must be ordered from the factory.

CHAIN COUPLING MOUNTING

Refer to Figure 2 (at right), Figure 1, page 4 and Figure 5, page
9 for component identification and the operator mounting slot
locations. Place the sprockets [ 3 ] and [ 4 ] on the chosen side of
the torsion shaft of the door and on the corresponding end of the
output shaft of the operator. The sprockets should be kept as
close as possible to the bearings. Fasten the connecting link to
each end of the door chain and loop the chain over the sprocket
[ 3 ] on the torsion shaft. Temporarily suspend the operator in its
mounting position using the chain over the sprocket [ 4 ] at one
end of the jackshaft and a rope or chain at the mid point (to
support the operator weight). With the chain tight and straight
and the jackshaft parallel with the torsion shaft, trace the
mounting slot on the mounting surface then lower the operator to
the floor.

IT IS ESSENTIAL THAT THE SURFACE
SUPPORTING THE OPERATOR BE RIGID
AND SECURE. FAILURE TO PROVIDE A FIRM
MOUNTING SURFACE WILL RESULT IN
DAMAGE TO THE DOOR TORSION SHAFT
AND THE PREMATURE FAILURE OF THE
OPERATOR.

If the construction permits, the operator should be mounted with
3/8 inch diameter bolts through the wall. If it is not feasible to go
through the wall, then use lag bolts to fasten the operator to the
mounting surface. Locate the four holes within the tracings of the
slots made in the previous step at the positions which will allow
for adjust-ment of the chain tension. After drilling the mounting
holes and instal-ling lag shields, if necessary, bolt the operator to
the mounting surface but do not completely tighten the bolts at
this time. Check the alignment of the sprockets, adjust their
positions on the shafts if necessary and tighten the set screws
securely on both sprockets. pulling downward on the operator to
remove slack from the chain, tighten the four mounting bolts.

Inspect the installation. There should be no slack in the chain but
neither should it be under severe tension which might shorten the
life of the bearings. If there is any flexibility in the system due to
construction of the surface supporting the operator or noticeable
deflection of the door shaft, it is advisable to install a shaft
support between the operator jackshaft and the door shaft to

prevent the loss of limit settings due to the possibility of the
chain jumping over the sprocket teeth. Shaft supports are
available from the factory.

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

Proceed to “Chain Hoist and Floor Disconnect Installation”.

INSTALLATION INSTRUCTIONS

DIRECT COUPLING MOUNTING

Figure 4, page 8 illustrates several positions suitable for

mounting the operator including center mount with direct
coupling to the torsion shaft. Direct coupling may also be
used in a side mount installation. Operators intended for
direct coupling require an internal speed modification and
must be ordered from the factory.

Refer to Figure 2, page 6 and Figure 5, page 9 for the
location of the operator mounting holes.

IT IS ESSENTIAL THAT THE OUTPUT
SHAFT OF THE OPERATOR AND THE
DOOR SHAFT BE CAREFULLY ALIGNED.
MISALIGNMENT OF THE SHAFTS WILL
CAUSE EXCESSIVE STRESS AND WEAR.

Raise the operator to a position which brings the door and
operator shafts into alignment and connect them together
with the flange coupling supplied with operator. Support the
other end of the operator jackshaft from the ceiling with a
chain or rope. Holding the operator in a vertical position,
carefully measure the distance from the operator mounting
plates to the wall. Lower the operator to the floor and
construct a secure mounting surface using the dimension
measured in the previous step. Again raise the operator to its
mounting position and re-connect the shafts. Mark the
mounting slots in the support structure, drill and securely bolt
the operator into place.

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

CHAIN HOIST AND FLOOR DISCONNECT
INSTALLATION

If the operator is furnished with a chain hoist (Model AUH), pass

the hand chain over the chain wheel and through the chain guides
on the operator clutch shaft (opposite end from the large pulley).
Fasten the ends of the chain together by opening and re-closing one
link using two pairs of pliers. If the chain is too long (standard
length for 16 foot high doors and below is 26 feet total length of
chain), shorten it to the desired length using the method described
above and discard the unused portion.
Fasten the chain hoist holding bracket furnished with the operator
to the wall approximately four feet from the floor. This bracket is
also used to hold in place the release chain for both the chain hoist
equipped units (AUH) and floor disconnect models (AUJ).

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 6 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.

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.

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 10 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 14, 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.

The AU series 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).

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 (Model AUJ) or using the
hoist chain (Model AUH). 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.

17

MAINTENANCE

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 clutch
must be tested periodically and adjustments made if necessary
(see page 15). The brake is adjusted at the factory and will need
periodic adjustment for wear. When adjustment becomes
necessary see Figure 10 on page 16 for the adjustment
procedure.

Test the reversing edge circuit at least once a month by
permitting the door to contact an obstruction while closing.

NOTES

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.
