4.4 Mechanical installation
4.4.1 General installation safety notes
• Never work on the actuator with the power switched on!
• Do not hold the extension tube while the unit is energized.
• Failure modes of the actuator should be considered to ensure it does not create harm.
4.4.2 Basic installation considerations
1. Only mount the actuator using the holes in the rear (a) and front (b) adapters. Check the model
number on the actuator product label (section 4.1) and then look at the ordering key (section 7.2)
to nd out your adapter type conguration. See the below drawings and table to nd out the exact
adapter dimensions.
2. Make sure that the actuator mounting position allows access to the cable connector cover plate (c), so
that it can be removed to allow access to the cable connector(s) (section 4.4.4).
3. The cable or cables (d) exit the cable slot at the rear of the actuator housing at delivery but can be
made to leave the housing at any point after the cable connector cover plate.
4. The hand wind input (e) must have enough free space around it to allow it to be operated
(section 4.4.5).
5. If external limit switches will be used, the mounting of the actuator must allow access to the limit
switch slots (f) running along the underside of the cover tube (section 4.4.6).

4.4.3 Mounting orientation and forces
1. The actuator can be mounted in any orientation and handle both pushing and pulling loads.
2. Always install actuator so that the force of the load acts in the center of the extension tube and the
rear adapter.
3. Only mount the actuator to the rear and front adapter mounting holes.
4. Only use solid mounting pins and support them at both ends.
5. The mounting pins must be parallel to each other both radially and axially.
4.4.4 Cable connector cover plate
1. The cover plate is held in place by a screw (M3 with Torx T10 head) that can be accessed through
the hole in the top of the cover plate (a). Keep in mind to mount the actuator so that there is enough
clearance to access the screw with a tool!
2. Once the cover plate is released it needs to be pushed about 20 mm (0.8 inch) in the direction of
the arrow symbol on the cover plate before it can be removed from the actuator (b). The connectors
are a part of the backside of the cover plate and can be accessed once the cover plate is removed.
3. Make sure to put the cover plate back correctly and torque the screw to 1.2Nm (10.6 in-lb) to ensure
that the actuator cover plate and connectors are properly sealed.
YES NO

4.4.5 Hand wind mounting and operation
1. Make sure when mounting the actuator that there is space enough between the rear adapter and any
object behind it to allow the hand wind to be operated!
2. To be able to operate the hand wind, remove the cover plug placed over the hand wind input (a).
3. Next, move the extension tube by turning the hand wind input hexagon socket (b) using a 6 mm male
hexagon key (c).
4. The maximum torque required to move the extension tube at the fully rated actuator load using the
hand wind is typically 4-6 Nm (35-50 in-lb).
Always make sure to switch o󰀨 the power to the actuator before using the hand wind.
Do not apply higher torque than 10 Nm (88 in-lb) to the hand wind input.
Never run the extension tube in to the end of stroke as that may damage the actuator.
Never use any type of drill or power tool to operate the hand wind.
4.4.6 Mounting of optional external limit switches
1. The external limit switches are mounted in the two slots (a) at the bottom of the cover tube.
2. Put the sensor (b) into one of the slots and and lock it at the desired position by turning the clamp
screw 45 degrees (c).
If the sensor is mounted in the immediate vicinity of magnetic components, the
switching characteristics of the sensor may change.

4.5 Electrical installation
4.5.1 General notes
• Make sure the leads/cables leading to the motor can handle the maximum motor current.
• An emergency stop is recommended to reduce the chance of a 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 slow blow fuse between the actuator and the power source.
4.5.3 Electrical connections
The actuator is always supplied with a power cable (a). Depending on which control option was selected, it
can also have a signal cable (b). The cable(s) have ying leads in one end for customer connections. In the
other end the cable(s) are integrated in to the cable connector cover plate (c) (section 4.4.4). The plug in
connector allows replacing the actuator without disconnecting the ying leads.
4.5.4 Lead cross sections
To avoid malfunction due to voltage drop the cross section of the leads between the actuator power
cable leads and the power source must be of su󰀩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.

4.5.5 Inrush current
At the start of the actuator there is an inrush current to the motor that will last between 75 to 150
milliseconds. See below table to determine the inrush current for the control option being used.
If using an AC powered power supply it must be sized to handle the inrush current (batteries
typically have no problem delivering the inrush current). Also contacts, switches and relays must
be sized appropriately to be able to handle the inrush current.
4.5.6 Brake resistor
If the unit is to operate with a helping load (pulling load) that are above 50% of the rated maximum
load, the unit must be equipped with a brake resistor (also see section 4.6.3). The resistor must have a
resistance between 2.3 - 3.3 Ohm and be able to handle at least 100 W.

4.6.1 General notes
• Avoid placing signal cables along power cables to reduce the risk of interference.
• Avoid using a vehicle earth as the return conductor. Instead use a two wire system to reduce
the risk of interference.
• In very sensitive applications or where there is a risk of interference we recommend using
shielded signal cables.
• Keep in mind that long cables in combination with small lead cross sections and low voltages
may lead to undervoltage and malfunction due to voltage drop.
• Relays or other coil operated devices should have spark protection to avoid interference.
• Never work on the actuator or the wiring with the power switched on!
4.6.2 Speed control by adjusting the input voltage
Electrak LL can not be speed controlled by adjusting the input voltage. When using battery
or full wave rectied direct current that are within the acceptable voltage limits, the built in
Electronic monitoring package will keep the actuator at the correct speed for the load in
question. Outside of the limits the actuator will be stopped (section 4.6.3). When using PWM
(Pulse Width Modulation) to speed control the actuator, the internal PCB will be permanently
damaged and cause malfunction.
4.6 Control options installation and operation

Thomson
Thomson Electrak®LL Actuator - Installation Manual - 2020-11 13
4.6.3 Onboard control functions (control type LEX)
Utilizing the internal control system the actuator will:
• Stop the actuator immeditately at each end of mechanical travel and throughout the stroke anytime
current exceeds a factory preset value for the rated load (over load condition). This value is adjusted
during operation automatically to provide consistent force. Resetting the actuator requires motion in
opposite direction to continue normal operation.
• Stop the actuator when the current move is nished in the situation where voltage or temperature
are outside their normal operating ranges. Once within the normal operating range the actuator will
automatically reset and normal operation can be continued.
Always turn power o󰀨 to the actuator before working on it to eleminate the risk of the actuator
making unplanned moves after it has carried out the automatic reset.
Power the actuator by connecting lead 2 to + Vdc and lead 1 to - Vdc in the power cable.
If using a brake resistor it should be connetc between leads 2 and 3 in the power cable. Make sure to use
the correct type of resistor (section 4.5.6).
To extend the actuator apply voltage between lead 6 and 8 in the signal cable. To retract the actuator
apply voltage between lead 7 and 8 in the signal cable.
The actuators will stop automatically when reaching the mechanical end of stroke in any directions and
motion will only be possible in the opposite direction.
External limit switches can be connected to leads 3 and 5 (stop extend) and 4 and 5 (stop retract) in the
signal cable in order to stop the motion in either direction before reaching the mechanical ends of stroke.
When a󰀨ected they will stop the actuator and motion will only be possible in the opposite direction.

Troubleshooting list
Issue Problem Solution
Actuator does not move,
makes no sound.
Actuator is not receiving
proper input voltage.
Ensure the actuator is being supplied with proper rated
input voltage.
Actuator makes buzzing
sound, does not move.
Actuator does not have
enough power and is stalled.
Ensure your power supply can provide enough current to
move the rated load.
The actuator, when powered,
is causing my fuse to blow.
Fuse is not rated for current
draw of the actuator.
Make sure that the fuse is rated for the in-rush current of
the actuator, which is typically 1.5 times the rated current
draw of the actuator at full load. Slow-blow fuses are also
recommended.
The actuator is not stopping at
the right place.
External limit switches are in
incorrect position or are not
working.
Control the functionality of the external limit switches.
