1. Preface
Dear customer,
Thank you for choosing a LogicS-2 / LogicS-3 motor control box for height
adjustable desks from LOGICDATA GmbH. You have purchased a state-of-the-
art product which complies with all safety requirements.
1.1. Appropriate Operation
LogicS-2 / LogicS-3 – motor control boxes must solely be used for the intended
application, control of height-adjustable desks. Only motors which meet the
specifications of LOGICDATA GmbH must be used to drive lifting columns. The
control box must be installed, initially operated and functional tested by
competent personnel only. Use other than described above is only allowed
with permission of LOGICDATA. The basic functionality is up/down movement
of the desk (doable with any handset).
1.2. Functionality LogicS-2 / LogicS-3
The motor control boxes LogicS-2 / LogicS-3 offer following functionality and
performance characteristics (however, the practical applicability of these
functions depends on the used handset):
•Control boxes are available for different mains voltages
•All LOGICDATA handsets are utilizable optionally
•Depending on type of the handset additional functionality (e.g. saving and
accessing memory positions, etc.) is available
•ISP (Intelligent System Protection)
•Configurable stop conditions (overtemperature, overcurrent, timeout, limit
switches)
•Configurable reset conditions
•Configurable duty cycle
•Mains cut-off with configurable turn-off time
•2 freely definable motor-groups
•Automatic motor detection
•PLUG DETECTION
•Up to 6 Memorypositions
•Additional pinch-protection with optional squeeze line
•Lock function with PIN code
•DRIVE-BACK function on various conditions
•AUTO-MOVE function
•FLEX MEMORY with random function
•SIT-STAND-Memory

1.3. Audience and Previous Knowledge
This user manual is intended for the following audience:
•Assembly personnel, which assembles and starts-up the height-adjustable desks
(mount control box and motors, configure the control box, etc.)
•Furniture assembly personnel, service personnel, which puts the desks into
operation on site in showrooms or directly at the end customer's place
To put into operation, mount and configure height-adjustable desks with the
LogicS control box, following skills are prerequisite:
•Basic mechanical and electronics skills
•Lecture of this manual
1.4. Performance Differences LogicS-2 / LogicS-3
LogicS-2 The motor control box LogicS-2 is suitable to control up to 2motors for
desk height adjustment.
LogicS-3 The motor control box LogicS-3 is suitable to control up to 3motors for
desk height adjustment.
Note: Further differences are listed in the LogicS-2 and LogicS-3
datasheets!

1.5. Safety Instruction Symbols
This manual contains safety advice with symbols to point out possible
dangers. The used symbols have the following meaning:
Danger: This safety instruction warns of imminent danger for life and
health of individuals!
Neglecting this advice may cause dangers to health, fatal injury and
damage to property!
Caution: This safety instruction warns of dangerous current!
Neglecting this advice may cause injuries and damage to property!
Note: This safety instruction points out important information you have to
consider for safe operation of the LogicS control box!

User Manual
LogicS-2 / LogicS-3
Page 6/33
Note: Note the commitment to read the user manual!
1.6. ISP – Intelligent System Protection
ISP is a state-of-the-art protection system developed by LOGICDATA. With ISP,
a possible bruise hazard is significantly decreased.
Danger: However, in exceptional cases a certain bruise hazard may be
present even with ISP activated because not only the motor control itself
but also the interaction between mechanics, motors and electronics is
crucial. Furthermore, stopping sensitivity is being influenced by
mechanical components, ambient conditions and the motor activity!
Therefore, LOGICDATA, as the control box manufacturer, cannot
completely eliminate this risk and we point out that we cannot be held
liable in the case of maloperation!
Consider following requirements for optimum operation of ISP:
To ensure the best possible operation of the anti-pinch function during
downwards travel, a mechanical braking system must be integrated in the
motor drive.
Note: Without such a braking system you have to expect decreased stop
sensitivity under load. However, when the desk is unloaded, the anti-
pinch function will operate correctly.
Note: As soon as ISP stops the movement of the height adjustable desk,
movement will only be allowed in the opposite direction (a movement in
the direction which triggered the ISP is not allowed)
