perfect condition and rated for the current requirements of all connected devices.
Power input throughput cables must be rated 16 A minimum, have three conductors 1.5
mm2(AWG16) minimum conductor size and an outer cable diameter of 5-15 mm (0.2-
0.6 inch). Cables must be hard usage type (SJT or equivalent) and heat-resistant to 90°C
(194°F) minimum. In the EU the cables must be <HAR> approved or equivalent.
Use only Neutrik powerCON TRUE1 NAC3FX-W cable connectors to connect to power
input sockets. Use only Neutrik powerCON TRUE1 NAC3FX-W cable connectors to
connect to power throughput sockets.
Assembly power supply cables following the instructions in this manual only (see page
12).

Before each use
Ensure that the rotator is correctly and safely mounted
Ensure that the attached load is correctly mounted
Warning! Do not use the rotator if any damage or error is found!
Isolate the rotator from power immediately of the power plug or any seal, cover, cable,
or other component is damaged, defective, deformed, wet, or showing signs of
overheating. Do not reapply power until repairs have been completed
Do not expose the rotator to rain or moisture.
Refer any service operation not described in this manual to a qualified technician.
PROTECTION FROM BURNS AND FIRE
Do not operate the rotator if the ambient temperature (Ta) exceeds 40° C (104° F).
Do not modify the rotator in any way not described in this manual.
Install only genuine Wahlberg parts.
PROTECTION FROM INJURY
Fasten the rotator securely to a fixed surface, rig, or structure when in use. The rotator is
not portable when installed.
Ensure that any supporting structure and/or hardware can hold at least 10 times the
weight of all the devices they support
If suspending from a rigging structure, fasten the rotator using the supplied Manfrotto
slim coupler and M12 bolt, nut, and washers supplied with the rotator according to the
manual, see page 10.
Always install the rotator as described in this manual. If the rotator is installed in a
location where it may cause injury or damage if it falls, install as described in page 10.
If possible, allow enough clearance beneath the rotator so it cannot cause any danger to
personnel beneath it. Else, adjust the lower limit accordingly following the instructions in
this manual.
Check that all external cobblers and rigging hardware are securely fastened.

Description
Rotator 281 is a rotator for stage use, mainly for use in theatres, shows and concerts.
It is designed for rotating lamps and other electrical devices. The rotator has a positioning
system that enables a Rotator to stop at any desired position. The load is up to 150 kg. The
rotation speed is between 0.15 rpm and 6.8 rpm.
The rotators are easily connected as a chain, allowing for advanced and creative ways of making
dynamic movements. The rotator is controlled by the DMX channels from the lighting desk. It
has a built-in positioning system which is utilized in locating the desired position. The positioning
system is controlled from a 16 bit DMX channel and is highly accurate; the rotator stops within
1°. The speed of the rotator is likewise controlled from the lighting desk, and it is possible to set
the left and right limits of the movement of the rotator, adjusting its span of motion. Six DMX
channels controls the wanted position and the speed of the movement, and the rotator finds the
position applied on the lighting desk. The movements are programmed as lighting and in
interaction with the light.
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 witch a PID regulator calculates the motor speed
and distance.
Rotator 281 should only be operated by an experienced DMX-controlled-lighting-desk-operator.
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 on the main. After
power failure the start and 0°position of the rotator needs to be reset before the rotator can
function again.
Manually operation of the rotator is only intended for mounting, service, and tests.

Area of use
The Rotator is intended for indoor use only. It is designed for rotating lamps and other electrical
devices at the weight and speed stated in "Technical Data". Any other use of the rotator may
result in a risk of injury of persons or equipment damage. Exceeding the load rating may cause
failure of the equipment.
Use only approved rigging connectors to secure the load to the rotator and do not modify the
shaft as this may damage the rotator and result in a risk of injury of persons or equipment
damage.
Do not modify the rotator. For any modification of your rotator, contact Wahlberg.
It is the customers' responsibility that any local restrictions concerning the use of the rotator are
complied with.
For indoor use only!
Caution! To reduce the risk of electric shock or injury: use indoors only
Caution! To reduce the risk of electric shock, do not expose to rain: store indoors!
Using for the first time
Important! The Rotator 281 must be protected from environmental factors such as physical
shocks and vibration during transportation and storage.
Warning! Read “Safety Information” on page 2 before installing, powering, operating, or
servicing the rotator. Before applying power to the rotator:
Check the Wahlberg Motion Design website at www.wahlberg.dk for the most recent
documentation and technical information about the Rotator 281. Wahlberg user manual
revisions are identified by the revision number in the bottom of each page.
Carefully review the “Safety Instructions” on page 2.
Check that the local AC mains power source is within the rotator power voltage and frequency
ranges.
See “Power cables and power plug” on page 2. Install a Neutrik powerCON TRUE1 NAC3FX-W
power input connector on a suitable power cable. If drawing the power from a mains power
outlet, install a suitable power plug on the power cable.

Physical installation
Warning! The Rotator 281 must be either fastened to a flat surface such as a floor or roof, or
clamped to a truss or similar structure. Do not apply power to the Rotator 281 if it is not
securely fastened.
Warning! The supporting surface must be hard and flat. Fasten the rotator securely.
Warning! Use only the supplied rigging clamps and M12 bolts. The clamp must be screwed into
the central holes in the rotator’s mounting brackets using the supplied M12 washers and M12
locking-nuts.
Fastening the rotator to a flat surface
The Rotator 281 can be fastened to flat surface such as a floor or roof. Check that the surface
can support at least 10 times the weight of all rotators and equipment to be installed on it.
Mounting the rotator on a truss
The Rotator 281 can be clamped to a truss or similar rigging structure.
When loading the rotator with full load it is important to use all 3 slim couplers when mounting.
To clamp a Rotator 281 to a truss:
1. Check that the rigging clamp is undamaged and that the rigging
structure can support at least 10 times the combined weight of all
Rotators and equipment to be installed on it.
2. Use the 3 supplied rigging clamp or contact Wahlberg Motion Design
for a replacement.
3. Fasten the clamps to the rotator with the supplied M12 bolts, nuts,
and washers in the holes in the mounting brackets of the rotator.
4. Block access under the work area. Working from a stable platform,
hang the rotator on the truss. Tighten the rigging clamp.
Mounting the rotator in an angle
The Rotator 281 can be mounted in any angle.
Warning! Always mount the load with the center of mass directly below the center of the axis.
Warning! The maximum load depends on the angle the rotator is mounted in. Refer to table
below
Maximum load:
Shaft - down 150 kg. (330 lbs.) only with 3 rigging clamps mounted!
Shaft - up 100 kg. (220 lbs.) only with 3 rigging clamps mounted!
Shaft –sideways 50 kg (110 lbs.) only with 3 rigging clamps mounted!
