1. INTRODUCTION
A. PURPOSE: This Crown Installation, Operation,
Maintenance and Parts Manual has been developed to
assist you in the installation, operation and maintenance
of your electric operator and thus enable you to utilize it
to its maximum e󰀩ciency.
B. MODELS COVERED: The manual covers current
models 1502-1 & 1502-2 Operators.
C. APPLICATION: The Crown Industrial Model #1502
Swing Door Operators are intended for use on large
interior industrial doors operated by trained personnel.
D. DESCRIPTION:
The model 1502 operator consists of a 90 volt, DC
permanent magnet gear motor, variable torque electric
clutch, right angle worm gear and internal limit switches.
The motor control is accomplished by means of an
electronic control package. The motor controls are
mounted in a remotely located control panel. The
operator shall mount above the door on the lintel of the
frame. Door connecting arms and door brackets are
included. The operator mounting frame and cover shall
be prime coated ready for nish painting in the eld. The
supply voltage should be 120 volt AC, single phase. The
control circuit will allow for two speed operation with the
run and creep speeds independently adjustable.

2. INSTALLATION AND OPERATION
A. GENERAL
The Crown 1502 Electric Door Operator has been
designed primarily for commercial and industrial
installations where the operator has to withstand
constant hard use. To ensure correct installation
and proper operation of the operator and associated
hardware, the following instructions are given:
(1) SHIPMENT CHECK: Included with the installation
packet is a copy of the packing slip for the components
supplied with the order. Compare the components
received with the packing slip to insure that all
equipment is complete.
(2) REVIEW INSTALLATION DRAWINGS: The
installation drawings show the layout of the door,
template drilling for the door and jamb, and general
terms used to describe the components. Review the
drawings to familiarize yourself with the equipment.
(3) CHECK THE DOORS: Prior to installing the
operator, conrm the doors are properly hung. 95% of
all door operator trouble is caused by doors not swinging
free of the oor and lintel. It is also very important that
all hinge pins are properly aligned and there is no hinge
binding.
(4) PREPARING THE DOOR AND LINTEL:
The door operators are handed (left and right) and
are supplied as push or pull to open (Refer to Figure 2
Operator Handing). Ensure proper backing and support
are available in the lintel and the door to receive the
operator and connecting arm. Remove the electric
operator from crate. Choose the appropriate drilling
template. Prepare the lintel for the operator.

the door bracket (Note: fasteners are supplied by
others). Attach the arms from the operator to the door
bracket. Manually swing door open and closed ensuring
both the door and operator function freely.
C. WIRING OPERATOR AND CONTROLS:
(1) No. 1502 Electric Operators are intended for
applications with motor branch circuits that have voltage
and current characteristics to meet the operators’
ratings. Branch circuit, branch circuit disconnecting
means, and branch circuit over current protection are to
be properly sized in respect to the operators’ horsepower
rating.
WARNING: Insure operator branch circuit is
disconnected from power source when installing,
adjusting or servicing operator.
(2) Be sure all power is o󰀨. Wire the electric operator
and controls according to the wiring diagrams provided
in the installation packet.
D. START-UP:

door reaches the full open position. (Light on
PLC turns OFF when activated)
(b) LSC = Limit Switch Close (Wired Normally Closed)
This limit shuts o󰀨 the operator when the door
has reaches the full closed position. (Light on
PLC turns OFF when activated)
(c) LSCO = Limit Switch Creep Open (Wired Normally
Open)
This limit activates the creep mode during the
end of open cycle. When the limit switch is
actuated the door travels in the open direction at
a reduced speed. (Light on PLC turns ON when
activated)
(d) LSCC = Limit Switch Creep Close (Wired Normally
Open)
This limit activates the creep mode during the
closing cycle. When this limit switch is actuated
the door travels in the closed direction at a
reduced speed. (Light on PLC turns ON when
activated)

Figure 6. Safe Swinging Power Door Operating Speeds
To adjust each individual limit switch, turn the screw
adjustment for each specic limit switch. Note that
depending upon the handing of the operator the cams
travel from either the clockwise or counterclockwise
direction to activate the appropriate snap switches.
(e) With the power turned o󰀨, manually swing the
door to the full close position. Check to see LSC (limit
switch close) is engaged. You can see the pointed cam
engaged the limit switch roller. Adjust the limit switch by
turning the limit switch adjusting screw until the cam just
engages the roller. You should hear the snap switch click
when it is actuated.
(f) With the power turned o󰀨, manually swing the
door to the full open position. Check the see LSO
(limit switch open] is engaged. You can see the cam
engaged the limit switch roller. Adjust the limit switch by
turning the limit switch adjusting screw until the cam just
engages the roller.
(g) With the power turned o󰀨, manually swing the
door to the full close position. Check to see LSCC
(limit switch creep close) is engaged. You can see the
extended can engage the limit switch roller. Adjust the
limit switch by turning the limit switch adjusting screw
until half of the extended cam travels past the roller.
When this limit switch roller is engaged the door will
travel at the creep speed during the closing cycle (creep
speeds are desirable during the nal opening and
closing positions for smooth operation).
(h) With the power still o󰀨, manually swing the
door to the full close position. Check to see LSCO (
limit switch creep open) is engaged. You can see the
extended can engage the limit switch roller. Adjust the
limit switch by turning the limit switch adjusting screw
until half of the extended cam travels past the roller.
When this limit switch roller is engaged adorable travel
at the creep speed during the opening cycle.
(3) Turn the Electric Clutch Controller in a
counterclockwise direction until "o󰀨".
(4) Turn the run-speed pot clockwise about half-way and
then turn the creep-speed pot clockwise to about 1/8 of
the way. Reference electrical schematic for the location
of both run and creep pots. Reference Figure 6. Safe
Swinging Power Door Operating Speeds.

3. MAINTENANCE
A. GENERAL
Very little maintenance is required on the 1502.
1. Periodically check for wear on the pivot points of the
arms.
2. Operators using the push arm assembly, should
have the two (2) zerk ttings greased once a year
depending on use.
3. Check electric clutch for proper function once a
month depending upon use. Fine tune though
electric clutch torque setting per installation manual
(Refer to step 6, Setting Electric Clutch Resistance).
4. Verify limit switches are set correctly. Periodically
check limit switches for proper adjustment.
(5) CHECK THE OPERATION OF THE MOTOR:
(a) Turn the power on.
(b) Activate the door actuator, verify that the motor is
turning in the correct direction.
The open relay "O" should light during the opening cycle
and the close relay "C" should light during the close
cycle. If they are opposite, the leads (M1 and M2) to
the motor may be switched and the motor rotation will
reverse.
(6) SETTING ELECTRIC CLUTCH RESISTANCE:
(a) Turn the Clutch Controller in a Clockwise
Direction to approximately 50%.
(b) Stand clear of door and pushed open actuator
button. Does the door begin the move without the clutch
slipping?
• If yes, then attempt to stop the door by applying
a pressure to the lead edge of the moving door once
the door has reached approximately the middle of the
opening. The clutch should begin to slip at and applied
pressure of approximately 25 lbs. Adjust the PS90
clutch controller accordingly.
• If no, then increase clutch torque clockwise on
the Clutch Controller until the door begins to move. For
each adjustment be sure to stand clear of the door.
(7) Reset the run and creep speed pots in the control
box to a combined equivalent speed ASP as ed in the
table on Safe Swinging Power Door Operating Speeds
(table on page 4). Be sure speeds are set for smooth
and safe operation of the door.
(8) Fine tune limit switches by repeating step 2 parts A
through D.
(9) SETTING RUN TIMER: (refer to electric schematic)
The run timer is an equipment safety feature which shuts
o󰀨 the electric motor. Set the run timer to shut o󰀨 10
seconds after a complete for close or open cycle.
(a) With the door and the full open position, depress
the actuator switch to signal operator to close the door.
(b) Allow door to fully close while watching the run
timer indicator light (Reference electrical schematic).
The run timer light should stay on approximately 10
seconds after the door has reached the full closed
position. If the run timer light is lit for more than or
less than this 10 second integral, adjust the run timer
pot accordingly. Turning the run timer clockwise will
increase the length of time. Turning the run timer
counterclockwise will decrease the length of time.
(10) OPTIONAL: Partial Open Feature
(a) Close the door to the full close position.
(b) Actuate partial open actuator, the door should
open approximately half-way and shut o󰀨. Turn the
partial open timer clockwise to increase the open width.
Turn the partial open timer counterclockwise to decrease
the open width (Refer to electrical schematic).
