Description
The Rotator is a spinning shaft unit with DMX control and an advanced positioning system
for stage use, mainly for use in theatres, shows, and concerts. It Rotator can spin props,
small set pieces, as well as lamps and other electrical devices.
The spinning shaft can rotate 360° continuously, and the positioning system enables precise
movements, allowing the Rotator to stop the shaft at any desired position with 0.5°
precision.
The Rotator can be used with the shaft mounted downwards, upwards (only 281), and
sideways (only 281).
With the shaft mounted downwards the Rotator 280 can carry a load up to 50 kg with a
rotation speed of 0.15-6.8 rpm, where the more advanced Rotator 281 can rotate up to 150
kg (shaft downwards) with a rotation speed of 0.15-6.8 rpm.
The Rotator is controlled by the standard DMX controlling signal, so a normal lighting desk
can be used to control the movement, programmed as normal light.
For a low number of Rotators, a standard lighting desk can be used, but when many
Rotators are used, more advanced desks should be used to maintain easy control of the
units.
The Rotator uses 6 DMX channels, and they control the position, speed, limits, and reset
functions.
The Rotator has an advanced internal positioning system with 16 bit, used for finding the
position desired by the operator. With a 16 bit positioning channel (ch1 and ch2) the
281.805.006

Date: 2017-10-24
operator set the desired position, and the Rotator will run to this position, with the speed
applied on the speed channel (ch3).
With channel 4 and 5 it is possible to start continuous clockwise (CW) and counter
clockwise (CCW) rotation. Optional, channel 4 and 5 can be used to set the soft clockwise
(CW) and counter clockwise (CCW) limits of movement, adjusting the Rotators span of
motion.
Channel 6 is used for Mode controlling with the possibility to change between positioning
mode, positioning mode with soft limit save enabled, and angular mode.
Multiple Rotators are easily daisy chained with power in-out and DMX in-Out, allowing to
create advanced and dynamic movements with 100’s of Rotators working together in the
same installation.
Safety functions
The
•
•
•
control system ensures that the motor only is powered when:
The control signal is reliable.
The position and speed control is on.
The motor position is calculated after which a PID regulator calculates the motor
speed and distance.
The Rotator should only be operated by an experienced DMX-controlled-lighting-deskoperator.
The lighting desk has to be programmed according to the manual, so the Rotator will stop
when the speed is put to 0 %. It is also possible for the user to stop the Rotator by
disconnecting it from the main. After power failure the start position of the Rotator needs
to be reset before the Rotator can function again.
Manual operation of the Rotator is intended for mounting, service, and tests. Other use
than that, should only be carried out with an emergency stop switch attached. Contact
Wahlberg Motion Design for enquiries regarding attachment of an emergency switch.

AC power
Warning! Read “Safety Information” on page 2 before connecting the Rotator to AC
mains power.
Warning! For protection from electric shock, the Rotator must be grounded (earthed).
The power distribution circuit must be equipped with a fuse or circuit breaker and
ground-fault (earth-fault) protection.
Warning! Socket outlets or external power switches used to supply the Rotator with
power must be located near the Rotator and easily accessible so that the Rotator can
easily be disconnected from power.
Warning! Check that the voltage range specified on the Rotator’s serial number label
matches the local AC mains power voltage before applying power to the Rotator. Do
not apply AC mains power to the Rotator at any other voltage than that specified on the
Rotator’s serial number label.
Power cables and power plug
The Rotator requires a power input cable with a Neutrik powerCON TRUE1 NAC3FX-W cable
connector for AC mains power input. The cable must meet the requirements listed under
“Protection from electric shock” on page 2.
Wahlberg Motion Design can supply the PowerCON input connector.
If you install a power plug on the power cable, install a grounding-type (earthed) plug that
is rated 20 A. Follow the plug manufacturer’s instructions. Table 1 shows standard wire
color-coding schemes and some possible pin identification schemes; if pins are not clearly
identified, or if you have any doubts about proper installation, consult a qualified
electrician.

Date: 2017-10-24
Data link
A DMX 512 data link is required in order to control the Rotator via DMX. The Rotator has 5pin XLR connectors for DMX data input and output. The pin-out on all connectors is pin 1 =
shield, pin 2 = (-), and pin 3 = (+). Pins 4 and 5 in the 5-pin XLR connectors are not used in
the Rotator but are available for possible additional data signals as required by the
DMX512-A standard.
The Rotator is subject to the common limit of 32 devices per daisy-chained link. Note that
if independent control of a Rotator is required, it must have its own DMX channels.
Rotators that are required to behave identically can share the same DMX channels. To add
more Rotators or groups of Rotators when the above limit is reached, add a DMX universe
and another daisy-chained link.
Tips for reliable data transmission
Use shielded twisted-pair cable designed for RS-485 devices: standard microphone cable
cannot transmit control data reliably over long runs. AWG24 cable is suitable for runs up
to 100 meters (328 ft.).
Never split a DMX line without using an opto-isolated RS-485 splitter/amplifier.
Terminate the link by installing a termination plug in the output socket of the last
Rotator. The termination plug, which is a male XLR plug with a 120 Ohm, 0.25 Watt
resistor soldered between pins 2 and 3, “soaks up” the control signal so it does not reflect
and cause interference. If a splitter is used, terminate each branch of the link.
Connecting the DMX
To connect the Rotator to data:
1. Connect the DMX data output from the DMX controller to the Rotator’s male 5-pin XLR
DMX input connector (DMX 512 IN).
2. Connect the DMX output of the Rotator to the DMX input of the next Rotator and
continue connecting Rotators output to input (DMX 512 OUT).
3. Terminate the last Rotator on the link with a 120 Ohm resistor.
The DMX lamp is the green led, next to the DMX-selectors.
− Glows constantly:
DMX connection is correct.
− Flashes:
DMX signal is missing or wrongly connected.

Attachment power (Only 281)
Warning! Read “Safety Information” on page 2 before connecting AC mains power to
the attachment power inlet.
Warning! Socket outlets or external power switches used to supply the attachment with
power must be located near the rotator and easily accessible so that the attachment
can easily be disconnected from power.
Warning! Check that the voltage range specified on the Rotators serial number label for
attachment power voltage matches the local AC mains power voltage before applying
power to the Rotators attachment power inlet. Do not apply AC mains power to the
rotators attachment power inlet at any other voltage than that specified on the
rotators serial number label.
Attachment connection plug
The Rotator requires a power and data input a Neutrik speakON NL4FX cable connector.
The cable for connecting the speakON plug on the rotator for the attachment power or
data, must meet the requirements listed under “Protection from electric shock” on page 2.
The attachment connection has four 1.5 mm2 conductors.
To install a Neutrik speakON NL4FX cable connector, follow the original Neutrik instructions
in appendix 3 on page 34.
Connecting the power cable
Refer to the section “AC power” on page 15 for installation of the power connection.

Emergency stop
There is no dedicated emergency stop for this Rotator. The Rotator is controlled from a
lightning desk, where it should always be set up with a button that sets the speed of the
Rotator in operation to 0%.
Normally lighting desks have a “blackout” button that sets all signals to 0% and this will
also cause the Rotator to stop.

MODE setting
The MODE setting allows you to operate the Rotator in different ways. Each MODE setting
has a given function. Each mode gives an opportunity for different operational settings of
the Rotator. The MODE is selected using the MODE selector on the Rotator.
The Rotator needs to be reset, before the positioning MODE is possible. The Rotator can be
reset manually or automatically. The Rotator must be reset each time its power supply has
been disconnected.
Read the passage about controlling the soft clockwise (CW) and counter clockwise (CCW)
limits, to explore and setup the rotator for your own particular needs.
Warning! Only operate the rotator when there is a clear view to the rotator and area
beneath/above or besides it, depending on the method used for mounting.
Warning! Before running the rotator, ensure that the ‘danger zone’ next to the rotator
is cleared to avoid risk of injury.
Warning! MODE 7 and MODE 8 is only for service and tests!
Warning! Before running the rotator in MODE 7 or MODE 8, ensure that the area
beneath the rotator is cleared so no people can be harmed.

The rough position and the fine position are multiplied in to a 16 bit channel.
The rough position is the MSB.

Position fine
This channel controls the position of the Rotator, with the speed set on DMX
channel 3.
This fine position works together with the rough position (DMX channel 1).
The fine position and the rough position are multiplied in to a 16 bit channel.
The fine position is the LSB.

Speed
This channel controls the speed and defines the maximum rotational speed of
the Rotator.
The Rotator runs with the set max speed, but slows down as closing in on the
wanted position.
This channel also works as a main brake; the motor does not run unless the
channel is set above 0%.
The speed-channel can also be used to make soft and slow movements or fast
and sudden movements.

Manual CW / Set
soft CW limit
This channel makes the rotator, rotate clockwise (CW). The channel value
determines the speed.
This channel controls the soft CW limit of the Rotator. If DMX channel 6 is set
between 51-54%, the soft limits for position mode is saved. By adjusting this
channel the Rotator rotates CW and when the channel is put to 0% the soft CW
limit is saved (if channel 6 is 51-54%).
5
Manual CCW / Set
soft CCW limit
This channel makes the rotator, rotate counterclockwise (CCW). The channel
value determines the speed.
This channel controls the soft CCW limit of the Rotator. If DMX channel 6 is set
between 51-54%, the soft limits for position mode is saved. By adjusting this
channel the Rotator rotates CCW and when the channel is put to 0% the soft
CCW limit is saved (if channel 6 is 51-54%).

Manual reset
When the rotator is ready, the first thing to do is to reset it. The CW-position needs to be
set manually, before the rotator is able to use for positioning run. To get the most precise
run, fit for your own needs, it is possible to regulate the CW- and CCW- end positions. This
is done manually on DMX channel 4 and DMX channel 5.
Reset example:
− The DMX channel 4 is set to 30% → the rotator starts to spin clockwise.
− Let it run until it reaches a desired position.
− Set DMX channel 5 is set to 30% → the rotator starts to spin counter clockwise.
− Let it run until it reaches a desired position.
The rotator is now reset and the CW-end position and the CCW-end position define the
total travel length of the rotation.
If you want to change the rotating length, simply just use DMX channel 4 and 5 to set new
end positions.
Positioning
When the Rotator has been reset and the soft limits is set, it is possible to use it for
positioning run.

Steady light
The set position has been reached and the motor has stopped.
The position is set on the DMX channel 1 and 2, which controls the rough-and fine-position.
Where 100 % is the soft CW limit and 0 % is the soft CCW position.
The speed is set on the DMX channel 3, where 100 % is the fastest and 0 % is the slowest.
The Rotator does not run unless the DMX channel 3 is set above zero, and DMX channel 3,
therefore also works as a main brake.
There are 2 modes the rotator position in. These are selected by the value on DMX channel
6.

Positioning Mode
If DMX channel 6 is 0-79%, the 0% position and 100% position is set by the user using DMX
channel 4 and 5. When saving positions DMX channel 6 must be set between 50% and 55%.
DMX channel 4 moves the rotator in the CW direction and sets the 100% position. Channel 5
moves the rotator in the CCW direction and sets the 0% position. When setting the end
positions the 100% position set by channel 4 should always be set first.
When the 0% and 100% position has been set, DMX channel 1 and 2 can be used to position
the rotator between 0-100% with the max speed determined by channel 3.
Angular Positioning Mode
When DMX channel 6 is 80-100% the rotator is in angular positioning mode and DMX channel
1 and 2 determines the angel the rotator moves to 0% is 0° and 100% is 360°. The rotator
will always move the shortest way to the wanted position unless it was doing a continuous
rotation set by channel 4 or 5 that was ended.
Example:
− The current position is 5° and the next set position is 350°.
→ The rotator will move 15° back to the new position.
− The rotator is moving continuously (by having channel 4 or 5 set) and the next set
position is 350°
→ The rotator will continue in the same direction until it reaches the new
position, when the continuous move is stopped.
→ If the continuous move is stopped when the Rotator has moved 10° pass its
wanted position it will not move back but do almost a full rotation to reach its
position.

Synchronized movements of multiple Rotators
If several Rotators are installed to perform synchronized movements the best result is
achieved by using a fading 16 bit position. The Rotators have a slight deviation in
performance of the motors, so some motors have a slightly higher maximum speed than
others.
This difference in speed can be solved by running the Rotators with fading positions, like
when fading conventional light over time, the position of the Rotator should be faded from
one position to another over a certain amount of time. In that way the Rotators will follow
the fade-curve, and multiple Rotators can follow the same fade curve.
When fading the positions:
1. The speed channel should be a set to 100 to gain the highest possible speed.
2. The position channel should be assigned as a 16 bit channel with MSB and LSB.
3. The speed of the fade needs to be slower than the maximum speed, so the motors
have speed enough to follow the fade-curve.
If the fade of the positions is too fast, the Rotators will move at the maximum speed, and
you will see the difference in the motor speed.
If the fade is to slow the Rotators will move – stop – move – stop, when the position
changes, thus giving a discontinuous movement.

Maintenance plan
The results of all the regular inspections are to be documented and kept available at the
company. The written result of the last inspection must be kept available at the site of
operation, e.g. by an inspection sticker on the Rotator showing the date of the inspection,
the basis of the inspection and the name of the inspector.
Before every use and weekly
Every time when rigging the Rotator, before running the Rotator – and at least every week
when the Rotator is in use:
− Check that the Rotator is safely and correctly installed/mounted
− Check that the Rotator’s load and LEDs are visible from the operating station
− Check the shaft and clamp for shaft for bends, corrosion, and other damages.
− Check that the load is securely mounted
− Check the conductors through the rotator for conduction.
Monthly
At regular intervals – but at least every month when the Rotator is in use:
− Check the mounting clamp for damages and proper fastening.
− Change damaged parts according to this manual.
Yearly
The Rotator has to be inspected by a specialist every 12 months.
Every 48 months
The Rotator should be inspected by an authorised expert every 48 months.
Checklist
Use the checklist accordingly; before each use, each month etc.

Life time of the rotator
It is Wahlberg policy to apply the strictest possible calibration procedures and use the best
quality materials available to ensure optimum performance and the longest possible
component lifetimes. The extent of wear and tear depends heavily on operating conditions
and environment, so it is impossible to specify precisely whether and to what extent the
performance will be affected. The expected lifetime of the rotator depends on the load,
mounted angle, as well as duty cycle.

Power defect
If the rotator does not react when the power is connected check the following:
− Check that the power plug is properly connected, both to the POWER IN plug on the
rotator and to the main power plug.
− Check that the fuse is tightly screwed on in the fuse cap, also if it has just been
changed.
− Check that the fuse is intact. It can be replaced with a new 2.0A fuse.

How to get started
1.
Mount the rotator according to the instructions on page 12.
2.
Set the DMX address using the 100, 10, and 1 switches. Set MODE 1
3.
Apply DMX from a Lighting desk, best is a desk with manual faders. Pull all channels on to 0%
4.
Apply power to the rotator.
DMX lamp should be lit, and the mode lamp should be flashing.
Position mode
5.
Set channel 6 to 52 % and channel 4 to 30%
The rotator will slowly turn CW.
6.
When the wanted CW end position is found - set channel 4 to 0% and channel 5 to 30 %
The rotator will slowly turn CCW.
7.
When the wanted CCW end position is found - set channel 5 to 0%.
8.
Set channel 3 to 50% and channel 1 to 25%
The rotator starts to rotate, with 50% speed, to the position 25% from soft CW limit.
Angular positioning mode
9.
Set all channels (1 – 6) to 0%
10.
Set channel 6 to 100% (Angular mode)
11.
Set channel 3 to 50% (Max speed) and channel 4 to 30% (Manual CW).
Now the rotator will slowly turn CW. Let the rotator run minimum one rotation
(must be done for each power cycle, so the Rotator identifies its angular zero position)
12.
Set channel 4 to 0% and channel 1 to 25% (Position).
Now the rotator will rotate CW until it reaches 90 degrees with 50% speed
13.
Set channel 1 to 75%.
Now the rotator will rotate CW until it reaches 270 degrees with 50% speed
Note: It is possible to change between constant CW or CCW rotation and angular positioning mode
while the rotator is running. During change from constant CW/CCW rotation the rotator will always
continue in the same direction until the wanted angular position is found. When the rotator is in
angular positioning mode it will select the rotation direction that will give the shortest direction.
Before each use
