Safety instructions
Please read the following safety information carefully. It is essential that everyone who is to connect,
install or use the system receive the necessary information and have access to this instruction
manual.
LINAK recommends that the actuators be used for push applications rather than pull applications.
It is essential that everyone who is to connect, assemble or operate the systems receive the
necessary information and have access to this instruction manual.
Before installation, removal or troubleshooting:
•Stop the actuator.
•Disconnect the power supply and remove the mains plug from the socket.
•Free the actuator from any load that may be released during the work.
Before starting:
•Make sure that the system has been assembled as described in this instruction manual.
•Make sure that the current to the control box is correct before connecting the system to a

risk of personal injury:
It is the manufacturer of the application who is responsible for implementing
appropriate safety measures designed to prevent personal injury in the event that the
actuator fails.
Warning!
Please note that any application in which the actuator is involved must not feature any
risk of personal injury, e.g. a risk of crushed fingers.

Technical data
The TECH-system type 273 consists of: a motor control unit, actuators and an operating unit. Four
versions of the motor control unit are available, with and without power supply. 12 different actuator
types are available, as well as four different standard LINAK operating units.
Description of the system
The TECH-system type 273 is an actuator system that has been developed for industrial purposes
consisting of up to four LINAK actuators. The system uses a specially designed motor control unit to
ensure that the actuators operate safely and in parallel. The TECH-system type 273 is suitable for
applications for very heavy lifts of up to 2000 kg total weight.
The motor control unit ensures that all actuators maintain the same speed and position. If a
synchronisation error exceeds the set deviation in pulses, all actuators are stopped.
An externally connected display can be used to configure the motor control unit to operate a number
of different functions. For example, it is possible to adjust the acceleration/deceleration time, separate
start levels, limit the stroke length, etc.

Fitting a DC-DC converter
When using a LA20, LA35 actuator or BL1 Lift column, the DC voltage to the Hall sensor in the
actuator must be regulated to a constant 12 V. To do this, fit the DC-DC converter, EM-311-DK
The converter is easily fitted in the TR-EM-273-T-230 box beside the transformer. The converter must
be ordered separately.
DC-DC converter
Order no.: EM-311-DK
Installing the DC-DC converter:
To connect the converter, see diagram on page 25.

Connection of the motor control unit
Terminal 1: Supply voltage (+ 10–35 V DC) smoothed voltage
Terminal 2: Supply voltage (- gnd)
Terminal 3: Separate (- gnd.) for reed/hall feedback from actuators
Terminals 4, 7, 10, 13: Voltage to motor on actuator (+24 V DC)

defined using DIP)
Terminals 18+19: Main switch/error reading. When terminals 18 and 19 are connected, the
system is interrupted These terminals can also be used as outputs for error messages – by
connecting an electric indicator light, for example (For additional information about error codes, see
the Error Reading section).
Terminal 20: If terminals 20 + 25 are connected, the actuators run FORWARDS
Terminal 21: If terminals 21 + 25 are connected, the actuators run BACKWARDS

end stop switches.
Terminal 23: Reset/Learning. If terminals 23 + 25 are connected briefly (under 5 sec.), error
messages will be reset. If the terminals are connected for more than 5 sec. the control unit will switch
to Learning mode.
Terminal 24: Analog input for signal to positioning (servo). Use parameter 2 to select 0–5 V or 0–10

Installing the actuators
When installing actuators, it is important to make sure that the actuators can move freely along their
full stroke length, without being limited by the mechanical construction. It is also important to ensure
that the application is not subjected to uneven twisting and traction, nor to unevenly distributed load.
NB! The actuator must only be secured using the piston end and rear fastening plate –
never the outer tube of the spindle or the motor housing.
For additional information, please refer to the data sheet for the actuator in question.
Connection of LINAK actuators
The majority of LINAK actuators are supplied as standard with a pre-fitted cable, and the actuators
are also fitted with different types of plugs depending on which control box has been selected for the
control operations. For operation with TR-EM-273, the actuators are typically supplied without plugs.
The cable may vary with regard to the number of conductors and the respective colours depending on
the type of feedback the actuator is fitted with. The pictures below show the different types of cables
that are fitted to the compatible actuators.
LA12 with reed
LA28/LP2.2 with reed
LA31 with reed

The new generation of actuators is fitted with minifit plugs in the motor housing, and are thus supplied
without fitted cables. In contrast to the cable types mentioned above, the supply and signal
conductors have now been separated and are thus in individual cables.
