Model SL Slide Door Operator Applications
Slide Door operators are intended for
commercial and industrial use on sliding doors
which use horizontal track.
Please refer to Figure 10, on page 10 for
basic installation layout of track.
A Slide Door operator when properly installed
will effectively lock the door in the closed
position.
Model SL Slide Door operators are used in
the following applications:
- Continuous Duty, Indoor Commercial
installations only
- For doors that require from 1/3 HP to 1HP
motors using single or three phase power.
- 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.

PREPARATION

Before starting the installation of the operator, the door
must be in good working condition. Inspect the door
and track for loose or missing hardware and test the
door manually for ease of operation. Lubricate door
rollers.
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. The rails are shipped
separately from the power head.
ELECTRIC DOOR OPENERS ARE DESIGNED FOR
DOORS IN GOOD WORKING CONDITION, AND

INSTALLATION INSTRUCTIONS 11
TO AVOID DAMAGE TO DOOR AND OPERATOR
ENSURE ALL DOOR LOCKS ARE DISABLED.
USE AN INTERLOCK SWITCH IF A LOCK IS
REQUIRED TO RETAIN FUNCTIONALITY.
WARNING
1. For single slide doors sliding right to open
locate first angle mounting bracket 9” to left of
opening, for doors sliding left to open locate
first angle mounting bracket 9” to right of
opening. (See figure 8)
NOTE:
For bi-parting doors this measurement is 15”.
See figure 9.
2. Set the assembled operator into position and
mark the holes for the angle mounting brack-
ets on the wall, as low as possible without in-
terfering with door travel. (See figure 10) Drill
holes in wall for mounting. Through bolts are
recommended for this purpose. If wall con-
struction does not permit the ue of through
bolts, lag bolts and shields may be used.
3. Secure the assembled operator to the wall.
IMPORTANT: BE SURE OPERATOR
TRACK AND DOOR TRACK ARE PARAL-
LEL. Check that the door clears the power
head when moving. Adjust the track location
on the mounting brackets to the desired posi-
tion and tighten all bolts. It is recommended
that at least one sway brace be used between
the wall and one of the track hangers for in-
creased rigidity, especially on large or heavy
doors. See figure 7A.
4. Mount the disconnect mechanism so that the
top of the bracket is no more than 2” below
the slider carriage ( See figure 8,10, and 11.)
This mechanism may be adjusted both front
and back and up and down to align the dis-
connect pin. It may be necessary to shim be-
tween the mechanism and the door to bring
the pin out into the centerline of the track.
Note: for bi-parting doors, mount both door
disconnect mechanisms. (See figures 9,10,&
11.)
5. It is necessary on a bi-part installation to bring
the doors to a fully closed position for proper
synchronization. With both disconnect pins
engaged in their respective carriages, connect
the drive chain to the bi-part slide assembly
with the hardware provided. See figure 5C
and 7.
6. Install disconnect chain lock as shown in fig-
ure 11, so it will function as described in figure
12.

SETTING THE LIMIT SWITCHES
1. Remove the cover on the electrical enclosure. There are
two limit nuts on the threaded limit shaft that 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) switch(es). Auxiliary switches
may also be present, they are used to control other
functions. These are mounted on a separate bracket
and should not be confused with the the OPEN and
CLOSE Limit Switches which are mounted on a bracket
secured to the base of the electrical enclosure box and
are somewhat hidden from view.
2. Manually set the door to a nearly closed position.
3. Refer to Figure 13. Depress the limit nut retaining
TO AVOID RISK OF ENTRAPMENT AND POSSIBLE
DAMAGE TO THE DOOR AND OPERATOR THE LIMITS
MUST BE ADJUSTED BEFORE APPLYING POWER TO
THE OPERATOR.
WARNING bracket away from the slots in the limit nuts. Turn the
CLOSE limit nut on the shaft until it engages the CLOSE
Limit Switch. The switch will sound an audible “click”
when engaged. If there are auxiliary present, the limit
switch will be the second “click”. Release the retaining
bracket and be sure that it engages in slots of both limit
nuts.
4. Manually raise the door to a nearly OPEN position and
repeat Step #3 with the OPEN limit nut and switch.
5. If auxiliary switches are present, the limit nut will actuate
them just prior to activating the open or close limit
switch. (This is preset at the factory.)
6. Manually move the door to a half open position to avoid
door damage due to incorrect power supply phasing.
On three phase units the door may initially run in the
wrong direction when power is first applied. With the
door in a mid position there will be time to stop the door
before damage can happen if incorrect phasing occurs.
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.

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.
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
NOTE: PowerMaster SL operators have been
designed and constructed for use with
voltages from 115 Volts AC to 575 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.
Note: All SL operators are pre-wired to accept
reversing edge components. To comply with UL
requirements, one of these systems must be
installed and wired to the operator. Refer to
Figure 14 for Edge component wiring.
For operator models not installed with reversing
edge components or photoelectric device,
ONLY ONE THREE BUTTON STATION OR A
CONTROL WIRED FOR CONSTANT
PRESSURE TO CLOSE MAY BE USED TO
CONTROL THE OPERATOR. THIS IS TO
COMPLY WITH UL SAFETY REQUIREMENTS.
IN THIS CASE THE CONTROL 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
CLOSING 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. Refer to Figure 14.
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

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.
1. Remove cotter pin from slotted hex nut and
clutch shaft.
2. Back off slotted hex nut until there is
insufficient tension on clutch spring to permit
clutch to drive door.
3. Tighten slotted hex nut gradually until there is
just enough tension on spring to permit operator
to move door smoothly, but to allow clutch to slip
if door is obstructed.
4. Be sure cotter pin is reinstalled each time
operator is tested for clutch adjustment and that
it is locked in place on completion of adjustment.
CAUTION NEVER COMPRESS CLUTCH
SPRING BEYOND 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, AND THAT THE CLUTCH IS NOT
SLIPPING BECAUSE OF LOOSE OR MISSING
HARDWARE, OR THE DOOR BINDING IN THE
TRACK. ANY SERVICE REQUIRED TO THE
DOOR, DOOR SPRINGS OR DOOR
OPERATOR MUST BE PREFORMED BY A
QUALIFIED PROFESSIONAL DOOR
INSTALLER.
The clutch pad 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 clutch
pad, 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

adjustment due to excessive coasting of the door
proceed as follows:
1. Turn off power to the operator.
2. Loosen lock nut.
3. Tighten adjustment nut to increase spring
pressure.
4. Secure adjustment nut with lock nut.
5. Turn on power and test operator.
6. If more braking is required, repeat steps 1
through 5.

1. Mount disconnect assembly to door as
shown in figures10 & 11 of manual. To
determine correct mounting height on door,
place disconnect assembly directly under
trolley traveler leaving 1/2” clearance
between trolley traveler and plunger. Mark
hole location on door. Extend plunger until
spring is fully compressed. Make sure
plunger has a good engagement in trolley
traveler and is not obstructed from fully
compressing the spring. Make Height
adjustments as necessary.
Note: Installation for Bi-Part fire slide door is
shown on next page.
A. When doors are open fused link must
extend into door opening.
B. When doors are closed fused link
support arms must slide past each other.
To accomplish this the disconnect
assemblies must be mounted at different
heights on each door as allowed by their
individual trolley travelers. They may also
be adjusted to separate depths off the door.
2. Adjust drive plunger to center of trolley
traveler, (see figure 10) unless offset is
required for bi-part installation.
3. Install chain lock as shown.
4. Adjustment collars are preset at the factory
but may be moved to make adjustments if
necessary.
