Technical data TECH-system Type 288-SAF is comprised of a motor control unit and an actuator. You can choose between 6 different types of actuator.

Description of the system TECH-system Type 288-SAF is designed for industrial applications and machines, such as ventilation, transportation systems, agricultural machinery, etc. The system is a single actuator system with a servo function, designed for incorporation into machinery or ventilation systems, in order to perform functions in connection with automated regulation, adjustment, dosing, coupling, reversal, etc. The actuator spindle position (stroke length) is determined by a signal sent either from a mechanical, manually operated potentiometer, joystick or PLC. Using 24 adjustable parameters, the TR-EM-288-SAF motor control unit can be set up to operate with several different types of actuator and input logic, as well as the actuator's pattern of movement. The parameters can only be changed using a TR-EM-236 programming interface. Changes are usually made before the complete machine is commissioned and when it is subsequently readjusted.

_______________________________________________________________________________________ Page 16 of 35 jan. 2019 ver. 06


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 machine is not subject 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.

WARNING! Never turn the actuator's spindle for possible adjustment during assembly. This results in immediate errors on positioning, when the actuator is then connected to the control and is started up.

Start/operation Before starting to use the system, it is important that all parameters in the motor control unit have been set correctly according to the specifications for the actuator in question. (see page 24)

Appropriate use:

• The system is only intended/designed for use as a component part in machinery or equipment used in an industrial environment.

• After fitting, test the system to check that it functions correctly. • The machine must be allowed free movement along the full stroke length of the actuator. • Bolts attached to the actuator's piston rod and rear fastening plate must be secure. • Ensure that the system is connected to the correct voltage.

Inappropriate use:

• Duty cycle must not exceed 10%: max. 2 minutes' operation followed by an 18-minute pause. • The actuator must not bear a load in excess of the max. load stated on the data plate. • The actuator must not bear a transverse load. • The actuator must not be subjected to knocks and violent jolts. • Unevenly distributed loads will exert oblique stress on the actuators. • The system must not be connected to a different voltage than the voltage stated on the data

plate. • The control box and power supply must not be covered. • The equipment is not suitable for use in the vicinity of flammable, anaesthetic mixtures of air,

oxygen or nitrous oxide (laughing gas). • The system is not suitable for machines which can be described as: • Medical devices • Equipment for use in the offshore industry (ATEX) • Aircraft • Nuclear power plant • The system must not be used until it is incorporated safely into the end product.

Maintenance

• Clean the surface of the systems at appropriate intervals to remove dust and dirt, and check for signs of damage and breakage.

• Check all connections, cables, housing and connectors, and check that the system functions correctly.

• With the exception of motor control units with PCB or those prepared for mounting in an electrical panel, the control boxes are sealed and maintenance-free.

• Check all connections, cables, housing and connectors. • For actuators with sealing class IPX6 rating and better: if cleaned using water, these units

should only be washed when the piston rod (spindle) is fully extended.

Reading monitoring values Using a TR-EM-236 portable serial interface handset, it is possible to read the current values for the system. Five values can be displayed. In the main menu, use ARROW DOWN to select the "Monitor Values" menu.

Explanation of monitoring values 1. Fault codes: (see below) 2. Motor current: 0 – 20 A = (0 - 200) 3. Target position: 0 – 100 % = (0 - 1000) 4. Realized position: 0 – 100 % = (0 - 1000) 5. Hour counter: Displays no. of operating hours (max. 65,535 hours) 4. Start counter: Displays no. of starts (max. 65,535) 5. Start counters over flow counter: Secondary counter for start counter Fault codes:

1. Power limit is reached 2. Time out 3. Disconnected due to overheating 4. Voltage overload

Service operation Service run is a function that makes it possible to "force" the actuator to run to one of its end positions, beyond any stroke length limit. The function is achieved by mounting a button between terminals 11 and 14 (see diagram page 23). The button must be activated for more than 5 seconds for the function to be in force. The required function is selected at parameter 14: 0 = Actuator runs IN on pressing the button 1 = Actuator runs OUT on pressing the button NB! The actuator only runs for as long as the button is pressed in. When the button is released, the actuator returns to the last position set.

Troubleshooting If an error occurs, the actuators will stop operating and the error condition will be indicated by a red LED on the PCB. The LEDs are visible when the cover of the control unit is removed.

Reading errors In the event of an error, the red LED will flash. The flashes mean the following:

1. power limit is reached: 1 flash 2. time out: 2 flashes 3. disconnected due to overheating: 3 flashes 4. voltage overload: 4 flashes

To reset errors Errors can be reset in 2 ways, either by activating a reset button mounted between terminals 11 and 14, or by running the actuator in the opposite direction. (See the diagram on page 23) The reset button must be activated for more than 5 seconds for the function to be in force. The required function is selected at parameter 15: 0 = reset by pressing the button 1 = reset by running the actuator in the opposite direction

Red LED = Error condition

Disposal of LINAK products To dispose of LINAK products, start by sorting them into different categories for recycling or incineration. We recommend that you dismantle your product as fully as possible for disposal, and that you reuse the parts. Sorting categories may include:

• metal • plastic • cables • flammable material • reuse

It is possible to subdivide within some of these categories. For example, “metal” can be subdivided into steel and aluminium, while “plastic” can be divided into ABS and PP. As an example of sorting, the table below illustrates the various categories under which the LINAK components are to be sorted.
