4.4 Mechanical installation
Always install actuator so that the force of the load acts in the center of the extension tube and the rear
adapter and support the mounting pins at both ends (a). Only mount the actuator to the rear and front
mounting adaptors using solid pins (b). The mounting pins must be parallel to each other both radially and
axially and be supported in both ends.
The actuator is equipped with an anti-rotation mechanism where the moving extension tube is internally
restrained from rotating. The maximum radial play allowed by the anti-rotation mechanism in the
extension tube is 10 degrees (c).
Failure modes of the actuator should be considered to ensure it does not create harm.
Warning! Do not hold the extension tube while the tube is moving or the unit is energized.

4.5 Electrical installation
4.5.1 General notes
• Make sure the leads/cables leading to the motor can handle the maximum motor current.
• We recommend to include an emergency stop to avoid any crushing hazard.
• Never work on the actuator or the wiring with the power switched on!
4.5.2 Fuse size
Protect the actuator and the wiring by using a fuse between the actuator and the power source. See table
below for recommended fuse size.
4.5.3 Wire cross sections
To avoid malfunction due to voltage drop the cross section of the wires between the actuator motor and the
power source must be of sufcient size. For longer cables than stated in the table calculations based on the
supply voltage, the current draw, the length of the cables and the ambient temperature must be done.

By switching the polarity of the voltage to the
motor the extension tube will change direction.
Make sure the switch used can handle the
maximum motor current.
Option N: the actuator voltage must be switched
off when reaching the ends of stroke or due to a
mid-stroke overload to avoid causing damage to
the actuator.
Option X: the actuator will automatically switch off
when reaching the ends of stroke or a mid-stroke
overload.
The direction of the extension tube is controlled
by switching the COM (common) output to the
EXT (extend) or RET (retract) inputs.
The actuator will automatically switch off when
reaching the ends of stroke or a mid-stroke
overload.
Two actuator versions with option E will have a
reduced load capacity at lower temperatures.
They are Wxx02-54AxxxE (2000 N high speed
version) and Wxx04-58AxxxE (4000 N version).

By switching the polarity of the voltage to the
motor the extension tube will change direction.
Make sure the switch used can handle the
maximum motor current.
Option P: the actuator voltage must be switched
off when reaching the ends of stroke or due to a
mid-stroke overload to avoid causing damage to
the actuator.
Option Z: the actuator will automatically switch off
when reaching the ends of stroke or a mid-stroke
overload.
Feedback output is most accurate under uni-
directional loading when approaching the position
from the same direction.
Absolute positioning is affected by load direction
and value, clearance in the mounting points,
actuator end play, gear backlash, feedback
sensor linearity and the control systems capability
to control the motor.
To minimize the effects of stroke tolerances,
feedback output is calibrated at the factory to
provide 2.5 VDC output at the nominal mid stroke
position of the actuator (for example at 50 mm
for a 100 mm stroke). Applications should be
designed for travel between the maximum retract
position and the minimum extended length.
The smallest amount of positional movement the
analog feedback sensor can detect and reect is
0.12 mm.

Option Y: the actuator will automatically switch off

Feedback output is most accurate under uni-
directional loading when approaching the position
from the same direction.
Absolute positioning is affected by load direction
and value, clearance in the mounting points,
actuator end play, gear backlash, feedback
sensor linearity and the control systems capability
to control the motor.
The digital feedback sensor outputs a two
channel quadrature signal which is used to
determine the travel direction and to calculate
the travel distance. It consists of two rectangular-
wave signals that transition from a HIGH to a
LOW state every 180 degrees of rotation and the
signal transitions of each output are offset by 90
degrees of rotation from each other.
The output type of the sensor is open collector.
The output essentially acts as either an open
circuit (oating) or a connection to ground.
The output usually has an external pull-up
resistor, which raises the output voltage when
the transistor is turned off. Because the pull-up
resistor is external and need not be connected to
the chip supply voltage, a lower or higher voltage
can be used instead. The pull up resistor needs to
be dimensioned and supplied by the customer.
The smallest distance that the sensor can detect
and reect:
Wxxxx-58A (standard speed): 0.1003 mm
Wxxxx-54A (high speed): 0.2006 mm

5.3 Safety Nut Information
Linear motion/thrust is produced by rotating a screw inside a threaded plastic nut, the nut is attached to
the extension tube. As the nut moves up and down the screw, it produces movement of the extension
tube and force (thrust).
• This unit is supplied with a metal safety nut which will hold a compression load in the case of
complete thread failure of the plastic nut.
• If the threads are lost in the plastic nut, the safety nut engages the lead screw and resolves the
load, preventing further actuator movement, requiring actuator replacement.
• The safety nut does not resolve tension loads.
5.4 Cleaning
The following recommended chemicals may be used to clean the surfaces of the actuator:
1. Mild soap and water solution
2. Vinegar and water solution
3. Mild bleach and water solution
4. Household cleaners (window or counter top cleaners).
5. Rubbing alcohol
6. Diluted citric acid cleaners
Under no circumstances is any acetone based solution to be used, as damage to housing or
nameplate may occur.
