(Actual machine design may vary)
1.Gearmotor: The motor is a 3 phase gearmotor with integral brake mounted to the side of
the winch frame.
2.Winch Frame: The winch frame is made from plate steel. The entire perimeter of the device
is to be considered the frame. The frame has a series of mounting points on the sides of the
frame along with the bottom base angles.
3.Grooved Drum/Drive Shaft: The steel drum is grooved for 3/16”operating line and will
rotate on a keyed drive shaft. The Drive Shaft is a solid round steel member that is connected
to the gearmotor and the grooved drum.
4.Cable Tension Device: These help maintain tension within the operating line. These pivot
back and forth as cable tension increases and decreases
5.Adjustable Limit: This is the black or yellow housing connected via Chain and sprocket to
the drive shaft.

Control station: The control station will typically be mounted to the proscenium wall. See the
following descriptions for use:
Key Switch: The key switch removes power from the control station and motion will not be
allowed with the key in the o position.
NOTE: The key does not remove high voltage power from the system and the main
disconnect should be used when servicing.
Open Button: This button is used to move the curtain open allowing the stage area to be
open for display.
Close Button: This button is used to move the curtain closed allowing the stage area to be
masked by the curtain.
NOTE: If the E-STOP (if provided) OR ultimate limit is deployed the system should not be
activated again until communication, visual and verbal, has been established between the
operator and all spotters, as well as a complete evaluation and determination of why the
E-STOP/ultimate was used. Once all matters are reviewed and security and safety is insured,
the system is ready to be operated again, conrm the direction in which the machine needs
to move and continue with operation.
For the safety of all concerned, the operating buttons are momentary push buttons,
otherwise known as dead man buttons. These buttons will allow the piece to move in its
desired direction until the piece has hit its limit position or when the button has been
released. CONTINUE TO HOLD THE BUTTONS FIRMLY DOWN UNTIL MACHINE HAS MOVED TO
ITS DESIRED LIMIT LOCATION.

INSTALLATION STEPS
1. Unload the packaged machinery.
Curtain Machines are shipped on a pallet. While packaged you must:
- Protect pallets from rain and humidity.
- Use safe material handling practices.
-Store packaged machinery in clean and dry locations that are protected from impact or
other abuse.
2. Installation layout must occur with the proper alignment of the machine to the diverter
pulleys utilizing proper eet angle of no greater than 1.5 degrees.
3. Once layout is conrmed use at minimum (4) 3/8" anchors, as determined by a licensed
engineered and per the instructions of the anchor manufacturer, in the perimeter mourning
holes provided in the base of the frame.
4. Install the Motor Control Cabinet and Control Station per the supplied wiring diagrams.
5. Once power to both control and motor is conrmed quick compress each directional
button on the control station to conrm proper drum rotation.
**NOTE: No limits have been factory set and a potential collision of equipment is possible**.
6. Install 3/16" Non-stretch operating cord to the drum utilizing 3 dead wraps on each line of
the cord installed onto the drum. Terminating the cord to the drum should be preferred as
specied by the cord manufacture. IMPORTANT: Ensure the cable page direction is correct in
relation to the direction of the curtain’s movement when the control buttons are depressed.
7. Terminate the other end of the drive line as required by the movement element (typically a
master carrier of a curtain track system).
8. Prior to running the system to full travel, test the operation by moving the curtain in each
direction by only 1/3rd of the available travel. Review for any misalignment or slack in the
operation cord. Adjust as required.
9. Once all rigging, cord terminations and cable tension has been conrmed, set the limit
according to the instructions on the following page.
**NOTE: Changing speed velocity will alter the manner and timing in which the limits stop the
curtain from moving. Best practice is to set the limits at a slower speed and adjust accordingly
as the desired speed is adjusted and ultimately achieved.

A. Setting the Limits
Limit switches determine the amount of travel allowed in the system. These positions are set
during the installation process and should not have to be re-adjusted. This system has a total
of 4 limit positions:
• Ultimate CLOSE limit position
• Primary CLOSE limit position
• Primary OPEN limit position
• Ultimate OPEN limit position
THESE LIMIT POSITIONS MUST BE SET DURING INSTALLATION, PRIOR TO THE USE OF THE
CURTAIN MACHINE.
In this system, the Ultimate positions are set just inches past the Primary positions. IT IS THE
INSTALLER’S RESPONSIBILITY TO SET ALL OF THE LIMIT POSITIONS IN ORDER TO OPERATE
AND MAINTAIN THE MACHINE IN THE SPECIFIC INSTALLATION.
If for any reason the system over runs the Primary position, the Ultimate limit will stop the
system from moving and completely shut it down, similar to the E-STOP. However, if the
Ultimate limit is reached [see note below], an “Over-ride” button (if equipped) must be
engaged in order to re-start the system. The system must then be run in the opposition
direction of the limit to get back to normal settings. This“Over-ride”button is located in the
MCC.
PLEASE NOTE: IF THE OVER-TRAVEL
LIMIT IS ENGAGED, A FULL INSPECTION
OF THE SYSTEM MUST BE PERFORMED
BEFORE OPERATING THE SYSTEM
OUT OF ITS OVERTRAVEL POSITION
TO SEE WHAT PROBLEMS OCCURRED
TO ALLOW THE OVERTRAVEL TO BE
REACHED.
On top of the center cam there are ve screws:
• Center (clamping) screw =Located at the center of cam stack
• Screw #1 =Ultimate Down limit position
• Screw #2 =Primary Down limit position
• Screw #3 =Primary Up limit position
• Screw #4 =Ultimate Up limit position

Please follow these steps to reset your limit positions.
1.Drive the machine to its desired position. Starting with the closed position tends to be
easiest. Locate the limit device with the center stack of cam per the above illustration.
2.Loosen the center clamp screw half a turn, counterclockwise.
3.Rotate the coordinating numbered screw (the #2 for the Primary closed position) in the
cam stack until the limit cam engages the base switch and creates an audible click. You must
conrm the correct direction to rotate the cam prior to adjusting the screw.
4.Once complete, tighten down the center clamp screw.
5.To adjust the Ultimate limit positions, rotate the cams in the same fashion, however, leave
them to rest in position so that it would engage directly behind the Primary position limit.
6.Repeat the same steps for setting the open positions limits.
7.When all limits have been set, perform a 5 time full travel duty cycle to conrm that the
limits in both directions are operating correctly.
8.Once all the limits are set, conrm that the center clamp screw is tight. Close and bolt the
limit enclosure lid.

The rst step in troubleshooting any circuit is to obtain a clear understanding of the circuit
and its function. If you are unaware of how a power or control circuit works, then you should
refer to a qualied technician to troubleshoot this portion.
Next, gain an understanding of the problem. Troubleshooting is very dicult if you do
not know what you are looking for. Obtain information from the operator who uses the
equipment. Often he can help to describe and isolate the problems more quickly.
ELECTRICAL TROUBLESHOOTING SHOULD ONLY BE PERFORMED BY QUALIFIED ELECTRICAL
TECHINCIANS
Eliminate the obvious, no matter how simple:
• Is the unit turned on?
• Are the disconnects turned on?
• Check the fuses, circuit breakers and overload relays.
• Are limit switches tripped or blocked?
• Look for overheating or warm areas, signs of leakage, smells, and recently made changes.
• THEN use the following procedures to isolate the problem to the control circuits, power
circuit, load, or incoming power.
Troubleshooting the incoming power supply, fuses and circuit breakers:
1. One of the most common problems found in all electrical circuits is a blown fuse or a
tripped circuit breaker. This is because the fuse or breaker is sized to open or trip in case of
trouble. The device that has opened or tripped has done so because of some fault on the
line. This fault may be located in any load connected to the line, a combination of loads, the
wiring, or even the fuse or breaker itself. In any case, the fuse must be replaced or the breaker
reset.
2. Although circuit breakers usually have an indicator to tell when they are tripped. Check the
incoming power supply for incoming power. It is a common mistake to assume that power is
present on incoming lines. Remember that these lines are also protected by other fuses and
breakers that may have tripped or failed for any reason.

3.Use a voltmeter to check the voltage between each pair of power leads. The supply voltage
should be within 10% of the voltage rating on the motor nameplate and other connected
devices. If the voltage is present, but out of specication, contact the manufacturer with
results. If the voltage is correct, check the enclosure for proper ground. To test for ground,
connect one side of the voltmeter to an unpainted metal part of the enclosure and touch
the other side of each of the line terminals. A voltage dierence should be indicated on the
voltmeter.
4.Next test the fuses or breaker for an open circuit. Apply power to the fuses or breaker.
To prevent any possible feedback through the connected loads, it may be necessary to
disconnect the load side of the fuses or breaker. Connect the meter from the line side of one
fuse to the load side of another (never the same one). A full voltage reading (phase to phase,
not phase to ground) indicates a good fuse.
Troubleshooting a control circuit:
1.Eliminate the incoming power as the source of trouble by connecting a voltmeter or test
light across the terminals and verifying that the proper voltage is present.
2.Once the control circuit has been determined to be the source of the problem, continue by
jumping each control device until the problem is found.
Troubleshooting limit switches:
1. Rotary limit switches should have:
a. Locking screws tight on switch cams.
b. Switches making contact with cams.
c. Wires tight in terminals.
