Introduction
The SceneControl 100 Motorized Rigging control system offers flexible control of a variable-speed rigging winch.
It uses a touchscreen operator interface, and offers simple modes of operation for rapid, easy use. A number of
powerful features provide great flexibility of operation.
The control system is designed to enable the safe operation of the motorized equipment. It is crucial that, before
operating any stage equipment, all operators should be given the necessary training and should then work only
under the direction of qualified supervisors. Stage equipment can be hazardous when improperly operated and
maintained.
While there are a number of principles that guide the safe operation of rigging equipment, there is one that will be
reiterated throughout this manual:
WATCH THE PIECE!
Whenever a set is being moved by the motorized rigging system, make sure that the operator can see the entire
piece throughout its path of travel. If the operator cannot see the entire piece, or the entire path, then spotters
must be positioned to supplement the operator's view. All spotters must be in clear and reliable communication
with the operator throughout the move. This is the level of vigilance that is necessary to safely operate rigging
equipment. Whenever you see the words WATCH THE PIECE! (or the initials WTP!) take a second to make
sure you are paying attention to the important stuff - the moving iron, not the flashing pixels!
While the information in this manual will not cover all possible situations (nor, due to the nature of theatre, could
such instructions be possibly written), it is intended to provide a guide to the safe and efficient operation of the
furnished stage equipment and its routine maintenance. No manual can replace constant vigilance and common
sense.
A routine maintenance schedule should be established and followed and appropriate records should be
maintained.
•Learn the feel, sound, and even the smell of your equipment so that you will immediately sense when
something is not correct.
•Study the capacities and capabilities of each system and its components.
•Thoroughly learn and practice the proper operating procedures.
•Before operating any equipment, inspect the machinery area, examine the equipment, and look for any
existing conditions which may affect proper operation or which could be affected by its operation. For
example, is anything fouling the equipment or in the path of its intended travel?
Further, any problem noticed during setup or operation of the stage equipment should be corrected
IMMEDIATELY. Someone’s life could be at stake.
We suggest that emergency procedures be established in case of fire or injury and that periodic drills be held.
In addition to routine maintenance, we strongly recommend that a qualified rigging firm be engaged to perform
periodic inspections and to correct any deficiencies discovered. These firms have personnel who are trained to
spot present hazards and many “potential” hazards. Routine maintenance also prolongs the useful life of

equipment and keeps it operating at peak efficiency for the quietest possible operation and so that less effort is
required on the part of the operator.
System Overview
The system includes a touch-screen control station, motorized winch, with limit switches and encoder, and
electronic motor controls. The system permits the operator to specify the winch operating speed, acceleration
time, deceleration time, and winch target. These parameters may be entered "on the fly", or may be recorded as
Presets, for later playback.
CONTROL SYSTEM
Each winch motor is connected to its electronic motor controls. These connections include wiring to the motor,
motor brake, winch limit switch, and motor encoder. The electronic motor controls for each winch may be housed
in an individual starter cabinet, or grouped together with others in motor control center cabinets (MCC's).
The electronic motor controls are connected through network wiring to a logic cabinet, which houses the
programmable logic controller (PLC). The PLC is a dedicated-purpose industrial computer. The PLC gathers
data from the electronic motor controls and issues commands to them. The logic cabinet also contains power
supply for the system power and emergency stop system. The system control panel is located on the face of the
logic cabinet.
System Components
EMERGENCY STOP SYSTEM
The Emergency Stop system is operated through latching mushroom-head Emergency Stop buttons in the control
system. These are located as required throughout the performance space. The E-stop buttons are joined in a
series loop; pushing any of the buttons will break the loop, and signal an emergency stop condition.
Pressing an E-stop button will immediately stop all motors in the system, by turning off the control power to each
winch starter. Pressing the emergency stop button will also signal the PLC that an emergency stop condition
exists. The Emergency Stop buttons latch when pressed; to release a non-illuminated E-stop button, turn the
button one-quarter turn clockwise (as indicated by arrows on the button) and allow the button to pop out.
MOTOR STARTERS
Each winch axis includes a starter, which contains circuit protection and electronic motor control devices. In
variable-speed winches, each starter includes a vector inverter drive, which takes in data from the motor encoder
and winch limit switches, provides motor power and brake release signals, and communicates with the
programmable logic controller. The vector inverter drive incorporates motor protection functions, including
overload sensing, and provides fault status information. Fixed-speed starters include a remote I/O system and
reversing starter with circuit and motor overload protection.

LIMIT SWITCHES
End-of-travel limits
Each axis is equipped with end-of-travel limit switches. End-of-travel limits are classified by their function, either
as normal limits, or overtravel limits. The normal limits stop motion in the selected direction, but permit motion in
the opposite direction. Each normal limit is backed up by an overtravel (or ultimate) limit; striking an overtravel
limit will cause the starter control power be cut off, preventing all motion of the winch. This is not a normal
situation, and a careful inspection of the winch must be conducted to determine the reason an overtravel limit
switch was activated. A maintenance procedure is required to clear this condition.
Both normal limits and overtravel limits are tied into the system control in all modes of operation, whether
operating from the main control system or from the maintenance controls on the motor control cabinet.
Limit switch types
Limit switch functions can be accomplished either with direct-struck limit switches, or with rotary limit switches.
Rotary limit switches are mechanically coupled to the winch drive mechanism. Each rotary limit switch has four
elements (up overtravel, up, down, and down overtravel). Direct-struck limit switches are struck by a piece of the
driven mechanism (e.g. a moving drum flange, or a cam mounted on the counterweight arbor, cable clew, or lift
guide).
CONTROL STATION
The SceneControl 100 Control
Station is the main control point for
the motorized rigging system. It
contains the following controls:
POWER keyswitch - Used to turn the
control system power on or off. Key
can only be removed when switch in
the off position.
EMERGENCY STOP - red latching
mushroom-head button– pushed in to
initiate an emergency stop condition,
pulled out to release and enable
normal system operation.
UP, DOWN, and GO TARGET
buttons - momentary-action buttons
which are pushed and held to execute
an action, previously selected on the
display screen.
SPEED - spring-return-to-center
joystick control, used to speed up or
slow down the execution of an action

(variable-speed systems only).
DISPLAY - the touchscreen display contains the control selections and status displays to operate the system.
The following sections of this manual detail operation of the system through the use of the display screen pages.
System Operation
BASE SCREEN – MULTIPLE WINCH SYSTEMS The Scenecontrol 100 can be used to
operate multiple winches from a single
control station. In multiple winch systems
the first screen that appears on power-up is
a winch selection screen.
An area at the bottom of this screen will be
blank if the emergency stop system is
healthy. The legend ESTOP FAULT will
appear if there when there is an emergency
stop condition. The touchbuttons on this
screen may be used to select the desired
machine for operation. Touching one of the
selection buttons calls up the base page for
that winch. The winch may then be
operated as explained in the following
sections of this manual. A touchbutton on
each winch’s base page may be used to
return to the winch selection page.
If the Scenecontrol 100 is set up to control only one winch, then that winch’s base page will appear on power-up,
as no selection page is needed.

WINCH BASE SCREEN Each winch controlled by the system has a
base screen associated with it. An area at
the top right corner of the screen is blank if
the emergency stop system is healthy, or
will display the message ESTOP FAULT if
an emergency stop button has been
pressed. There are a number of functions
on this page
POSITION FIELD: This POSITION field in
the upper center of the screen displays the
current position of the set batten (in decimal
feet above the stage floor).
TARGET FIELD: When the base screen
opens up, the current position will also be
displayed in the TARGET field, below this.
To designate a new target, touch the
TARGET numeric field. A numeric keypad will open; use it to key in a new numeric target. When you touch the
ENTER key on the keypad, the new value will be transferred to the TARGET field, and the keypad will close.
SPEED FIELD: (Variable-speed systems only) When the base screen opens up, the default speed will appear in
the SPEED field, below the TARGET field. The speed is expressed in feet per minute. To designate a new speed
value, touch the SPEED numeric field. A numeric keypad will open; use it to key in a new numeric target. When
you touch the ENTER key on the keypad, the new value will be transferred to the SPEED field, and the keypad
will close.
DEFAULT VALUES: There are four touchbuttons at the right of the screen that can be used to load values with a
single touch. The SUL button will load the Soft Upper Limit into the TARGET field. The SLL button will load the
Soft Lower Limit into the TARGET field. The POS AS TRGT button will load the current position into the TARGET
field. The DFLT SPD will load the default speed into the SPEED field (variable-speed systems only).
PRESET LOAD: The touchbuttons at the left of the screen (P-1 through P-8) are used to loads presets. When a
preset button is touched, the associated description will appear in the PRESET COMMENT area at the top of the
screen. The target and speed values for this preset will appear in the TARGET and SPEED fields.
SCREEN JUMPS: The buttons at the bottom of the screen (PRESET RECORD, PARAM PAGE, STATUS PAGE)
provide "jumps" to other screens and procedures in the control system. These are detailed in other sections of
Touchscreen display winch base screen

this manual. Multiple winch system will also have a BASE PAGE button, which is used to return to the winch
selection page.
WINCH OPERATION- DIRECT CONTROL
When a winch base screen is opened up, the current position is displayed in the POSITION and TARGET fields,
and the default speed is displayed in the SPEED field (variable-speed winches only). To run the winch up or
down from this point, push and hold the GO UP or GO DOWN button on the control station. The winch will
accelerate to the default speed and travel until the GO button is released, or until the winch reaches its Soft Upper
or Soft Lower Limit. To alter the winch speed during operation, move the speed control joystick handle - moving
the joystick up will increase the speed proportionate to the degree of joystick movement; moving it down will
decrease the speed proportionately. Fixed-speed units will only operate at their designated speed.
If a different speed is required for the move, enter the new speed prior to pushing the GO UP or GO DOWN
button. To designate a new speed value, touch the SPEED numeric field. A numeric keypad will open; use it to
key in a new numeric target. When you touch the ENTER key on the keypad, the new value will be transferred to
the SPEED field, and the keypad will close. Once this value is entered, run the set directly as described above.
NOTE: Operation of all machinery controlled by this system uses a form of "Deadman" operation. In this type of
operation, the operator must push and hold a button to run a set, and release the button to stop. This is done to
assure that the operator may not initiate a move and then leave the operator station while the move is in progress.
WARNING: Never move a unit which you, the operator, do not have in direct view. Damage or injury may occur if
a unit is moved without first checking that the unit is clear to move. If you cannot maintain a clear view of the unit
throughout the move, arrange to have spotters located where they can see it, and be sure to have a reliable way
of communicating with them throughout the move.
WINCH OPERATION- TARGET CONTROL
There are several ways to designate a target for winch operation. First is to enter the target directly. To do this,
touch the TARGET field. A numeric keypad will open: use it to key in a new numeric target. When you touch the
ENTER key on the keypad, the new value will be transferred to the TARGET field, and the keypad will close.
A pre-recorded target may also be loaded into the TARGET field by touching the SUL (Soft Upper Limit), SLL
(Soft Lower Limit), POS AS TRGT (Position as Target) or one of the Preset buttons (P-1 through P-8).
Once a target has been designated, the winch may be run to that target by pushing and holding the GO TARGET
button on the control station. The winch will accelerate to the designated speed and travel until it reaches the
target. If the GO TARGET button is released before the winch reaches the target, the winch will decelerate to a
stop at that point in its travel. The speed of travel may be varied by using the joystick, as described under Direct
Control, above.

Use this to key in the appropriate user name,
then press the ENTER key on the keypad.
Follow the same procedure in the password
field to enter the password.
When these have been successfully entered,
the winch preset record screen will appear.
Once on this page, enter a preset number (1-8) by touching the ENTER PRESET NUMBER numeric field. A
keypad will open on the screen; touch the desired number (1-8) and then touch the ENTER key. The preset
record screen will re-appear, and the preset comment, target and speed will appear in the appropriate fields. If
the preset has not been previously recorded, these fields will be blank. If the preset has been recorded, and you
do not wish to write over this information, then select a different preset number.
Once the desired preset number has been selected, enter a comment describing the preset by touching the
ENTER PRESET COMMENT data field. An alphanumeric keypad will appear; use it to key in the comment,
followed by the ENTER key. The preset record screen will re-appear; enter the desired target and speed,
following the same procedure.
Once the preset information has been successfully entered into all fields, touch the PRESS TO RECORD button.
The prompt “ARE YOU SURE?” will appear, along with YES and NO buttons. Press the YES button to save the
preset, or the NO button to stop the save process.

PARAMETER PAGE
From a winch base screen, the PARAM PAGE touchbutton opens the parameter page for that winch.
The parameter page displays certain winch
values, and provides a place where an
authorized user can manipulate them. The
BASE PAGE jump button at the bottom left
of the screen will return to the winch base
screen.
Values displayed on this page are
password-protected. Certain crucial values
are protected by the system level password.
These are indicated by and (S) following
their descriptor. Other values have the
indication (U) following their descriptor.
These values may be adjusted by an
operator logged in with the User level
username and password. If an operator is
not logged in, touching a numeric entry field
will pop up the user name and password
entry fields. To enter the user name, touch
the user name field; an alphanumeric
