Technical data
The TECH-system type 239 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. Ten different actuator
types are available, as well as four different standard LINAK operating units.
Description of the system
The TECH-system type 239 has been developed for industrial purposes and is composed of two LINAK
actuators. The system uses a specially designed motor control unit (TR-EM-239) to ensure that the
actuators operate safely and in parallel.
If the motor control unit cannot maintain parallel operation between the actuators, the actuators are halted
so as to prevent the risk of personal injury or mechanical overload. The motor control unit is fitted with a
power switch and a temperature fuse with power gain.
The FORWARD and BACK commands can be received in continuous or impulse signal mode.
In continuous activating mode, the actuators continue to operate for as long as the command signal is
activated.
In impulse activating mode, only a single impulse is required to start and stop the movement of the
actuators.
An externally connected display can be used to configure the motor control unit to operate various
functions. For example, it is possible to adjust the acceleration/deceleration time, limit the stroke length,
etc.
The TECH-System type 239 is compatible with a range of different LINAK actuators.

Fitting a DC-DC converter
When using a pair of LA20, LA23, LA35, LA40 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-239-T-230 box beside the transformer. The converter must be
ordered separately.

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-239, 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.

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.
