If the actuator's current consumption rises above the set limit, the actuator regulates and tries to keep it
below the set current limit by reducing the PWM and therefore also the speed accordingly. The actuator
does this continuously until the actuator stops moving (mechanically blocked) - something that is determinedby monitoring the Hall feedback signal. If there are no changes to the Hall feedback signal during the set
time frame, the Integrated Controller will cut power to the H-bridge motor circuit.
If the actuator is stopped due to the above-mentioned criteria, it automatically drives slightly in the opposite
direction to reduce the torque in a blocking situation.

Current cut-offs
The principle behind the current cut-off measurement is an ‘above limit’ and a ‘below limit’ accumulating
counter. When the time-out counter reaches a specific value the current cut-off goes into effect. The timeout value is pre-set at 500 ms.

Mounting guidelines
LINAK® linear actuators are quickly and easily mounted by slipping pins through the holes on each end of
the units and into brackets on the machine frame and the load.
The mounting pins must be parallel to each other asshown in Figure 1. Pins, which are not parallel to eachother, may cause the actuator to bend and become
damaged.
The load should act along the stroke axis of theactuator, as off-centre loads may cause bending andlead to premature failure. See Figure 2.
Make sure the mounting pins are supported in bothends. Failure to do so could shorten the lifespan of theactuator. Also, avoid applying a skewed load onto theactuator.

Figure 1

The actuator can rotate around the pivot point in the front and rear end. Because of this, it is of highimportance that the actuator is able to move freely over the full stroke length, both during the development
and daily operation. Please pay special attention to the area around the housing, where parts can betrapped and cause damage to the application and actuator.
In applications with high dynamic forces, LINAK recommends not using the fully extended or retracted
position over a longer period of time, as this can damage the endstop system permanently.

Mounting Guidelines•

The mounting pins must have the correct dimension•

The bolts and nuts must be made of a high quality steel grade (e.g. 10.8).

•

No thread on the bolt inside the back fixture or the piston rod eye.

•Bolts and nuts must be protected to limit the risk of them falling out.

•

When mounting the bolts for the back fixture or the piston rod eye, do not use a 			torque that is too high. This will stress the fixtures.
Instruction concerning the turning of the Piston Rod Eye and Inner Tube:•

When mounting and taking into use, it is not permitted to make excessive turns of the piston
rod eye.

•In cases where the eye is not positioned correctly, it is permitted to first screw the eye down to its
030618/DS
bottom position, at a maximum torque of 2 Nm (1), and thereafter turn it outwards again,
at a
maximum of 90 degrees (2).

Warning!
If the actuator is used for pull in an application where personal injury can occur, the following is valid:

It is the application manufacturer’s responsibility to incorporate a suitable safety arrangement, which will
prevent personal injury from occurring, in case the actuator should fail.
Warning!
LINAK® actuators are not designed for use within the following fields:• Offshore installations			• Aeroplanes and other aircrafts• Nuclear power generation

LA25 User Manual | 14

Dimensions

Electrical installation
For Standard actuators:•

To ensure maximum self-locking ability, please be sure that the motor is shorted when stopped.
When using soft stop on a DC-motor, a short peak of higher voltage will be sent back towards thepower supply. It is important when selecting the power supply that it does not turn off the output,
when this backwards load dump occurs. The power supply must be monitored externally and cut
off in case of current overload.

For IC actuators:•

As long as the actuator is powered, actuators with Integrated Controller ensure that the motor isshorted when stopped.

LA25 User Manual | 15

Mounting of cables

1. Unscrew the cover

2. Remove the cover

3. Plug in the cable gently
without using any tools

Removing cables

4. Screw the cover back onto the actuator
The torque of the cover screw
is approx. 1.5 Nm

5. Use a screwdriver to pull up
the cable

When changing the cables on a LINAK® actuator, it is important that this is done carefully, in orderto protect the plugs and pins. Before the new cable is mounted, we recommend that the socket isgreased with vaseline, to keep the high IP protection and ensure an easy mounting. Please be surethat the plug is in the right location and fully pressed in before the cable lid is mounted.
Please note that if the cables are mounted and dismounted more than 3 times the plugs can bedamaged. Therefore, we recommend that such cables are discarded and replaced.
Also note that the cables should not be used for carrying the actuator.
We recommend to take some precaution and design the wire connection in a way, where the cableend is kept inside a closed, protected area to guarantee the high IP protection.
NOT valid for ATEX cables, please refer to the ATEX section for correct cable mounting on ATEX
actuators.

Signal GND

For correct wiring of Power GND and Signal GND- please see figure below•

Current cut-offs should not be used as a stop function! This might damage the actuator. Current cutoffs should only be used in emergencies!

•

Current cut-off limits are not proportional with the load curves of the actuator. This means that thecurrent cut-offs cannot be used as load indicator.

•

There are tolerances on the spindle, nut, gear wheels etc. These tolerances will have an influence on thecurrent consumption for the specific actuator.

•

For actuators with analogue feedback it is recommended to fully extract and retract the actuator on aregular basis, thereby activating the limit switches. This recommendation ensures precise positioning.

*A Hall pulse consists of two Hall counts. A Hall count occurs every time the signal changes state(high to low or vice versa).

It is possible to run Parallel with a single power supply and to run each actuator with separate power
supplies. Only standard power and signal cables are available for Parallel.
If separate power supplies are used, they must have the same potential, and the power supply GND(Blue wires) must be connected.

LA25 User Manual | 41

BusLink Software Tool and the Parallel System
The BusLink software tool is available for Parallel and can be used for configuration, manual run anddiagnostics (service counter)
For more information and easy set-up of BusLink, please follow the link to view the Quick Guide for BusLink
here.
Please note that the BusLink cables must be purchased separately from the actuator!
Item number for BusLink cable kit: 0147999 (adapter + USB2Lin)
Only through the BusLink software tool is it possible to state if the system is Parallel or Non-Critical Parallel.
Via this tool it is also possible to reconfigure the whole system from one system to the other.

The Parallel System• The system does not have to run on one main power supply only – it can be supplied by individual
supplies corresponding to the number of actuators in the system. Please respect the actuator 		
specifications regarding voltage level and current consumption!
• It does not matter where the IN/OUT signal is applied. The signals of all actuators can be connected• When all actuators are connected, a Master will automatically be chosen. E.g. with 5 actuators in one 		system there, will be 1 Master and 4 Slaves. The Master can control up to 7 Slaves• If 'Run in same direction after overload' is not applied, the actuators are blocked for movement in that
direction until an activation in the opposite direction has been made, or the system has been re-powered• Before entering BusLink mode, all actuators must be disconnected. It is only possible to configure one
actuator at a time through BusLink• When changing the actuator configuration, it is important that all actuators in the system have the same
configuration before the system starts running. Otherwise, the actuators will not run• Actuators will be pre-programmed from our production as 2, 3, 4, 5 etc. Parallel systems. Through 		
BusLink it will be possible to add or remove actuators to/from the system.
• In case an actuator drops off the line due to e.g. a damaged signal cable, the Parallel system will stop 		
immediately• In case one of the actuators is broken, the system will not move; not even after re-powering. The broken
actuator needs to be replaced before the system can run again. The system will only run when it is 		complete or configured to a Non-Critical Parallel system via the Buslink software tool

Only for Non-Critical Parallel Systems•••

The Non-Critical Parallel system offers auto-detection for every single power up if a new actuator isadded to the line (system)
To add or remove actuators from the system, the system needs to be shut down and powered up again.
Please be aware that after re-powering, the system will not detect if an actuator is missing!
If adding a new actuator to the system, be aware that the actuator needs to have the same configuration(Non-Critical Parallel) as the existing ones; this can be done via the BusLink software toolLA25 User Manual | 42

System Monitoring for Parallel
If one of the actuators is experiencing one of the following error conditions, the actuators
will immediately STOP:
•
•
•
•
•
•
•
•

H-bridge fault
Out of the temperature range (high duty cycle protection)
Overcurrent (current cut-off if one or all actuators go in mechanical block)
SMPS fault
Endstop reached fault switch
Hall sensor failure
Position lost
Overvoltage (43 V DC)

Alignment of the Parallel Actuator System
If the actuators are not in Parallel when starting up, the next movement will run in the following manner:Start position

Running outwards

When completely aligned, theParallel run continues outwards

Start position

Running inwards

When completely aligned, theParallel run continues inwards

LA25 User Manual | 43

Parallel Manual Service Mode
With the Parallel Manual Service Mode it is possible to drive one or more Parallel actuators separately byusing the Red and Black wire from each actuator.
An example: if there are 4 actuators in the system and one is removed, the remaining 3 actuators will still
be operational simultaneously - so long as they are connected via the Violet and White wires, and giventhat 'Parallel manual service mode' is activated on at least one of them.
For activation of 'Parallel manual service mode', please follow the instructions below:

Test of Conducted and Radiated Emission (EMC)
All TECHLINE® actuators have been tested in accordance with EN55011 class B (2007) (CISPR 11). A 1 m
cable has been used in the test set-up.

Actuator without H-Bridge
1) For normal operation the following is valid:••

Radiated emission requirements are met
Conducted emission requirements are met. However, to meet with these requirements, a capacitor has
been mounted across the motor wires outside the actuator, and tests have then been made with thiscapacitor. Capacitor values for some of the TECHLINE actuators can be found in the scheme below

To comply with EN55011 class B (2007) a capacitor must be added across the motor wires, or the connected
control box must have similar/better filtering. The actuator is not delivered with a built in capacitor, because
then it would not be possible to PWM the motor.
Please view the scheme below for the correct choice of capacitor for the actuator in question:

2) For systems/operations that use PWM-control it is up to the customer to test and meet the requirements.

Actuator with H-Bridge
1) For normal operation with soft start/stop the following is valid:•••

The actuator has been tested when operating with constant 80%-PWM.
Radiated emission requirements are met
Conducted emission requirements are met2) For systems with LINAK® PWM regulation (among other things Parallel operation and speed regulation)
the following is valid:••

Radiated emission requirements are met
Conducted emission requirements are met3) Speed regulation:•

If the speed is regulated below a nominal speed of 80% (80% PWM), it is necessary to mount a filter
in order to comply with the conducted emission requirements. For systems/operations that are speed
regulated, it is up to the customer to test and meet the requirements
