See Page 10 for the entrapment protection installation guide.

MODEL MD OPERATOR APPLICATIONS:

Drawbar operators are for commercial and industrial use on
sectional overhead doors which use horizontal track with
normal radius. A draw bar operator is not suitable for
doors with high lift exceeding 24 inches or vertical lift
doors. The installation requires a minimum clearance of 5
inches above the high arc of the door (the highest point
reached by the door at any part of its travel). Add 4 feet, 8
inches to the door height (4 feet, 2 inches for a 10 foot high
door) when measuring for the back-room required to install
the operator. When properly installed a drawbar operator
effectively locks the door in the closed position.

The Model MD (drawbar) operators are used in the
following applications:

-Limited Duty Commercial installations only

-Rate of operation shall not exceed 10 cycles of openings
and closings per hour, maximum of 75 cycles per day.

-Indoor Use Only

-Up to 14 foot high doors with a maximum area of
approximately 196 square feet (will vary depending on
door construction, consult factory)

- To operate in Momentary Contact To Close mode and
comply with the UL325 Entrapment Protection
requirements effective Aug. 29, 2010, the door system must
include one of the following (a, b, or c):
(a) Linear Corp. Photo-Beam System that consists of an
emitter, Part No. 217792 and detector, Part No. 217800 for
doors as described above up to 30 FT wide. See Page 10.
(b) Any Miller Edge ME, MT/MU, and CPT family of
edges, with suffix T2, must be connected to the SM-102
Edge Module, Recognized by UL as per UL325 2010 on 08

-29-2010 for door as described above. See Page 10.
(c) A Vitector Fraba OSE 2-wire Photosystem as
Recognized by UL as per UL325 2010 on 08-29-2010 for
door as described above. See Page 10.
The manufacturer of this operator strongly recommends
installation of one of the entrapment protection device
above and states that one is REQUIRED where any
automatic, remote or manual control is used to activate the
door.

OPTIONAL FEATURES:

Digital Radio Controls: Open, Close and Stop operation.

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

Timer to Close Operation: Two of the programmable

operation modes (T & TS), closing delay is adjustable from 5
seconds (factory set at 30 seconds) to 5 minutes in five

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, adjust the springs for proper
counterbalance of the door.
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.

PREPARATION

The rails and drawbar chain/hardware package are shipped
separately from the powerhead.

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.

TO REDUCE THE RISK OF SEVERE

WARNING

INJURY OR DEATH:

READ AND FOLLOW ALL INSTALLATION INSTRUCTIONS!

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

• Remove all pull 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. See Page 9.

• Model MD 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).

• 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 door operator at least 8 feet or more
above the floor if the operator has exposed
moving parts.

• 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,

b) at a minimum height of five feet above the
floor so small children cannot reach it,

c) away from all moving parts of the door, and

d) far enough away from the door, or positioned

such that the user is prevented from coming in
contact with the door while operating the
controls.

Do not overtighten the clutch adjustment to

compensate for a poorly working door.

Install the Entrapment Warning Placard next to

the control station in a prominent location.

All warning signs and placards must be

installed so they are visible in the area of the door.

After installing the opener, all safety features

must be tested for proper operation (see page 20).

For products having a manual release, instruct
the end user on the operation of the manual
release.

RAIL/CHAIN ASSEMBLY

Refer to Figure 1 parts illustrations. The part names and
item numbers are referenced identically to the part
names and numbers in the assembly procedures
that follow. Before starting assembly of the
operator track check for the proper
length. The tracks are supplied for
8 Feet and 10/12/14 Feet high
doors. The tracks should
be three (3) feet
longer than the
door height. If the
tracks supplied
with the operator
are more than
three (3) feet
longer than the
door height it will
be necessary to
cut off two (2) feet
(or 4 feet for 10
FT doors) from
the power head mounting end as shown in Figure 2.

10 FT DOORS

RAIL/CHAIN ASSEMBLY INSTRUCTIONS

107068

Figure 2

CAUTION: WHEN NECESSARY TO CUT THE TRACK ENSURE THE ENDS ARE LINED UP AS IN FIGURE 2.

1) Assemble the operator track by assembling the items as shown in Figure 2.

2) After the track is assembled, position track assembly onto the operator power head and attach with four 3/8”-16 x 1” bolts,

lock washers and nuts (supplied in a separate hardware package #100470).

3) Referring to Figure 1 , 2 and 3 (below) , slide the trolley onto the track with the chain take up bolt lug (C) toward the power
head. Thread one 3/8-16 keps nut (attached star washer) onto the Chain take up bolt with the keps part (attached star washer)
away from the chain attachment end. Insert the chain take up bolt threaded end through the lug hole on the trolley (C) just far
enough to start a second 3/8-16 keps nut. Attach one end of the chain to the opposite end of the threaded stud using a 3-piece
chain link (provided). See Figure 3.

4) Install chain around drive sprocket at operator head then around idler at front end of rail and thread through opening at fro nt
end of carrier. If the rail is equipped
with a chain guide-spacer near its
center (12 foot rail or longer only) pass
the chain over it in one direction and
under it in the other direction to
separate the two lengths of chain.
Apply initial tension by pushing
forward on the carrier while pulling
chain tight through opening in the
carrier in the direction of D. When
maximum tension has been applied by
this means, swing chain forward and
insert retaining plate, E, in place.
Insert 1/4-20 x 5/8 hex head machine
screw through retaining plate, E, and
tighten plate in place. Make final
adjustment of chain tension to remove
excess sag by adjusting nuts on
threaded rod at chain lug, C.

TEST THE DOOR OPENER’S SAFETY FEATURES AT LEAST ONCE A MONTH. After
adjusting either the force setting or the limit of travel, ALWAYS RETEST the Operator’s safety

features. Failure to ADJUST THE OPERATOR PROPERLY may cause SEVERE INJURY OR
DEATH.

DO NOT over adjust the force setting to compensate for a poorly working door.

To prevent the motor protector from tripping - Do not exceed 10 door cycles per hour.

IMPORTANT: The hardware box contains a caution label which states: “This door is operated by
a light duty operator. To prevent the motor protector from tripping - Do not exceed 10 door cycles

per hour.” Permanently install this label adjacent to the door, near the push button station, at the

eye height of the average adult, approximately six feet above the floor). Do not paint over this
label.

If possible, USE THE MANUAL RELEASE only when the door is closed. Use caution when using
this release when the door is open. WEAK OR BROKEN SPRINGS MAY ALLOW THE DOOR
TO CLOSE RAPIDLY, CAUSING SEVERE INJURY OR DEATH.

KEEP THE GARAGE DOOR PROPERLY BALANCED. See the door manufacturer’s owner's

manual. An improperly balanced door COULD CAUSE SEVERE INJURY OR DEATH. Have a
TRAINED DOOR SYSTEMS TECHNICIAN MAKE REPAIRS TO CABLES, SPRING
ASSEMBLIES AND OTHER HARDWARE.

Inspect and maintain your door system as described in this manual.

SETTING THE SWITCH SELECTABLE OPERATING MODES

15

Changing the Switch Selectable Operation Modes

The following modes are selected by setting the on-board dip
switches, Figure 20 at right shows where the switches are
located on the operator control board. For each Operational
Mode, the switches are set to either ON or OFF according to
the table at right below. For all the modes, if an approved
entrapment protection (EP) reversing device as described on

page 3 of this manual is attached to the input labeled “Photo”, it

will function as noted. Once an approved EP device is
recognized by the control board it is monitored for correct
operation. If the device becomes inactive then the mode will
default to constant pressure activation for close regardless of
the dip switch setting. In order for any of the Momentary
Contact to Close operation modes (B2, TS, T) to become active
an approved Entrapment Protection (EP) Reversing device (see
Page 3) must be properly installed and connected to the
operator. The switches must be set to one of the six
Operational Mode combinations for the operator to function.
In order for the NO (Normally Open) Reverse on NC

SETUP MODES

Setup Modes

Various operating characteristics can be modified via the
setup modes. The operator is moved to the close limit
position and the on-board dip switches (see Figure 20, page

15) are TEMPORARILY set according to the table at right to
enter a Setup Mode. The on board OPEN and STOP buttons
are used to modify the characteristic. Once set, the values are
stored in non-volatile memory.
These values are set to factory defaults that should be
satisfactory for many applications. ALL VALUES AS

DESCRIBED HERE CAN BE RESET TO THE FACTORY
DEFAULTS AS FOLLOWS:

Remove 24 VAC power from the control board.
Press and hold the on-board stop button.
Re-apply 24 VAC while holding the on-board stop button.

After completing the procedure to modify the operating
characteristic the switches must be returned to the originally set
Operating Mode setting (see section previous).

Delay on Reverse Setup

To help prevent stress on the door components, this feature
allows for a delay time between the door stopping and reversing
when a command to reverse is received as the door is closing.
The factory default time is 0.75 seconds; the minimum time is

0.4 seconds; the maximum time is 2 seconds.

After moving the door to the close position and temporarily
setting the switches to the appropriate settings in the table,
pressing STOP will reset the time to the minimum setting.

Every time OPEN is pressed, 200 mS is added to the time (up to
the maximum).

Setup Mode Switch 1 Switch 2 Switch 3 Switch 4

Delay on Reverse ON ON ON ON

Close Limit Delay OFF ON ON ON

Auto Close Timer OFF OFF ON ON

Maximum Run Time OFF ON OFF ON

Changing the dip-switch setting to any other setting will save
the new time. Return the dip switches to the originally set
Operating Mode setting (see section previous).

Close Limit Delay Setup

To provide for irregularities in the floor, this feature allows for
the door to continue to travel down after the Reverse Cutout
Limit is activated. The factory default time is 0.32 seconds; the
minimum time is 0.12 seconds; the maximum time is 0.66
seconds.

After moving the door to the close position and temporarily
setting the switches to the appropriate settings in the table,
pressing STOP will reset the time to the minimum setting.

Every time OPEN is pressed, 0.02 seconds are added to the time
(up to the maximum).

Changing the dip-switch setting to any other setting will save
the new time. Return the dip switches to the originally set
Operating Mode setting (see section previous).

OPERATION & ADJUSTMENT INSTRUCTIONS

Auto Close Timer: N/A

Mid-Stop Limit Setup

This features provides a timing function to stop a door as it is
traveling open at a Mid Stop position instead of the full open
position. The door can then be moved to the full open position
if desired by pressing the Open button. A single button input
when the door is at the mid stop position will cause the door to
begin moving in the close direction. The factory default is not
set; the minimum run time to mid-stop limit is 6 seconds.

After moving the door to the close position and temporarily
setting the switches to the appropriate settings in the table,
pressing STOP will remove the mid-stop limit setting.

Pressing OPEN will start the door open. When the door reaches
the desired mid-stop position, press STOP.

Changing the dip-switch setting to any other setting will save
the mid-stop limit position. Return the dip switches to the origi­nally set Operating Mode setting (see section previous).

Note: The door must move a sufficient distance to fully disen­gage the Reverse Cutout Limit nut from the Reverse Cutout
Limit switch to set the mid-stop limit.

Auto Close Timer Setup

This feature allows for a modification of the amount of time
between the door reaching either the Mid Stop or the Full Open
position and automatically starting in the close direction. The

Auto Close feature is only active when the operator is set to the
T or TS Operating Mode (see section previous). The factory
default is 30 seconds; the minimum time is 5 seconds; the maxi­mum time is 5 minutes.

After moving the door to the close position and temporarily
setting the switches to the appropriate settings in the table,
pressing STOP will clear and turn off the auto close timer.

Every time OPEN is pressed, 5 seconds is added to the time.

Changing the dip-switch settings to any other settings will save
the new time. Return the dip switches to the originally set Oper­ating Mode setting (see section previous).

Maximum Run Time Setup

This feature provides for a maximum amount of time the motor
will be energized after an input is recognized. The factory de­fault time is 30 seconds; the maximum time is 60 seconds.

After moving the door to the close position and temporarily
setting the switches to the appropriate settings in the table,
pressing STOP will reset the time to the factory default setting.

Pressing OPEN will start the door open. The run time will be
recorded when the door reaches the open limit. To prevent nui­sance problems, 0.75 seconds are added to this time. Pressing
stop before the door reaches the open limit will stop the door
and reset the time to the factory default.

Changing the dip-switch setting to any other setting will save
the new time. Return the dip switches to the originally set Oper­ating Mode setting (see section previous).

The clutch serves to protect the door, the electric operator and
other equipment from undue stress or damage caused by starting
forces and/or an obstruction to the door. It should be set no
tighter than is necessary to smoothly and consistently move the
door throughout its full range of travel. When properly set, it
will slip freely if the door should encounter an obstruction, and
it should be possible to stop the travel of the door by hand.

WARNING: Before adjustment remove power to the
operator.

To adjust the clutch, loosen the jamb nut, and turn the adjusting
nut, as shown at right. Make adjustments in 1/4 turn increments.
Always re-tighten the jamb nut against the adjusting nut before
running the operator to prevent clutch from changing its setting.

CAUTION

NEVER COMPRESS CLUTCH SPRING BEYOND

THE POINT LIMITED BY THE DESIGN OF THE

OPERATOR OR REPLACE IT WITH A

HEAVIER SPRING

Due to changing conditions of the door and normal wear, it may
be necessary to occasionally readjust the clutch to obtain
dependable operation.

WARNING: BEFORE DOING SO BE CERTAIN THAT
THE DOOR IS IN GOOD WORKING CONDITION,
PROPERLY COUNTERBALANCED AND THAT THE
CLUTCH IS NOT SLIPPING BECAUSE OF LOOSE OR
MISSING HARDWARE, BINDING IN THE TRACK,
RUBBING AGAINST THE DOOR STOPS OR
DEFECTIVE OR MISADJUSTED SPRINGS. ANY
SERVICE REQUIRED TO THE DOOR, DOOR SPRINGS
OR DOOR OPERATOR MUST BE PREFORMED BY A
QUALIFIED PROFESSIONAL DOOR INSTALLER.

The fiber disk will wear during normal operation and should be
replaced when it becomes difficult or impossible to sufficiently
tighten the clutch to obtain smooth operation of the door when
it is in good working condition. To replace the fiber disk, first
loosen the motor mounting bolts and remove the V-belt then
the clutch adjusting nuts, spring and clutch pulley. Check
condition of V-belt before reassembly and replace if required.
After reassembly, adjust clutch as described previous.

ADJUSTED AND ANY ENTRAPMENT

PRTOTECTION DEVICES CONNECTED

BEFORE APPLYING POWER TO THE

OPERATOR TO SET THE LIMITS.

SETTING THE LIMIT SWITCHES

1) With the cover open on the electrical enclosure, reference
Figure 23 below. There are two (2) switches (A and B) mounted
to the „V‟ bracket (F). The switches are activated by the two limit
nuts (C and E) 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 switch, that send a
message back to the motor control board to stop the door.

2) For original installation setting, the door and operator
trolley should be positioned at the fully closed position. If this is
the case, depress the Limit Nut Retention Plate (D) so it
disengages from the slots in the limit nuts and move the Reverse
Cutout Limit Nut (E) on the shaft until it engages the Reverse
Cutout Limit Switch (A) (see Step 5 for an explanation of the
Reverse Cutout function). You will need to listen for an audible
click. Move the Open Limit Nut (C) to the center of the threaded
shaft. Release the retaining bracket and be sure that it
engages in slots of both limit nuts. If the door and
operator trolley are at some other position other
than fully closed, depress the Limit Nut
Retention Plate (D) so it disengages
from the slots in the limit nuts and
move the both the Limit nuts to the
center of the threaded shaft. Release
the retaining bracket and be sure
that it engages in slots of both limit
nuts.

B

from the slots in the limit nuts. Turn the OPEN limit nut (C)
on the shaft until it engages the Open Limit Switch (B). You
will need to listen for an audible click. Release the retaining
bracket and be sure that it engages in slots of both limit nuts.

5) With all due care use the built-in three button station on
the motor control board or the wall mounted three button
station to lower the door to the fully closed position and
repeat Step #4 with the Reverse Cutout Limit nut (E) and the
Reverse Cutout Limit switch (A). The actual Close Limit
position is a timed function whereas the door continues to run
for a certain period of time after the Reverse Cutout Limit
switch is activated. This amount of time (Close Limit Delay)
is factory set to 0.32 seconds and will provide reversing
cutout of approximately 4 inches from the floor for a door
traveling at 12 inches per seconds. If the door fails to reverse
when an object at least four inches high is placed in its path
(see Testing, page 21) it may be necessary to adjust the Close
Limit Delay time, see procedure on page 16.

6) Move the door to the fully open position then the fully
closed position and observe the stopping position. Reset the
Limit Nut(s) per above instructions if desired.

7) A fine adjustment can be done by loosening the screws
holding the Limit Switches to the V bracket and moving the
switch within the slots on the bracket.

3) With all due care use the built-
in three button station on the motor
control board or the wall mounted
three button station to raise the door

OPERATION & ADJUSTMENT INSTRUCTIONS

OPERATION & ADJUSTMENT INSTRUCTIONS

TESTING

21

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 3­button wall station, first observe that each directional 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.

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 trolley striking the stops on the rail.

The MS Series operators are equipped with a reversing circuit
and to allow for Momentary Close Contact operation an
approved entrapment protection device as described on Page 3
needs to be properly installed and connected to the operator. To
test it for proper reversal, place an object beneath the leading

edge of the door. The door should stop, pause and reverse when it
comes into contact with the object provided the height of the
object exceeds the cut out point set for the Reversing Cutout
Limit switch (approximately four inches).

CAUTION

DO NOT STAND UNDER DOOR

TO TEST REVERSING FEATURE.

USE A STURDY 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, test each of these
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 is engaged when the release
chain on the connecting arm is pulled to release the door arm
from the trolley. The door can then be manually opened or
closed by physically moving the door. If it is difficult to pull the
release chain and/or the door arm appears to be under excessive
compression, reset the CLOSE limit slightly to reduce the door
travel in the close direction.

MANUAL OPERATION

WARNING

FAILURE TO TEST REVERSING SYSTEM
COULD RESULT IN DEATH OR SERIOUS

INJURY. TEST THIS SYSTEM ONCE A MONTH.

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 Figure 22, page 18). The brake is adjusted at
the factory and may need periodic adjustment for wear. When
adjustment becomes necessary see Figure 21 on page 17 for
the adjustment procedure.

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

WARNING

ALWAYS DISCONNECT POWER TO

THE OPERATOR BEFORE SERVICING,

CONNECTING ACCESSORY DEVICES

OR MAKING ADJUSTMENTS.

MAINTENANCE

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.
