The LTC table controller
Thank you for purchasing our Controller. The well-shaped controllers can be
easily mounted below a table top or into a crossbar of a height adjustable table. A
variety of control panels and control modes enables the user to find the optimum
solution for many applications.
This instruction will show how to install and how to operate the controller.
Application
The LTC Controller series is designed and can be exclusively used to control
motors for the height adjustment of tables. Verify that the performance
parameters of the motors and the connections of the motors fit the parameters
and connections of the controller!
If used for other applications neither the function nor the safety can be ensured!
Therefore, such use is not permitted, and warranty will be voided if used in
applications outside the table height adjustment area.
Whom is this document prepared for
This document is an installation and operation instruction for the LTC series
Laing Table Controllers and its accessories. The document is dedicated to
manufacturers of height adjustable table frames and tables.
This document is not intended for end users!
Precondition for the use of this document
This document describes the installation and operation of the Controllers. It is
assumed, that the controller has been configured for the application in which it is
intended to be used! Program all parameters for the table the controller is
intended to be mounted to, before actual installation.
Do not install system before programming!
Safety instructions
Attention There are no user serviceable or repairable parts inside the controller!
Do not open the controller. If opened, the warranty will be void.

• Before any work is done with the products, read the instruction manual
and follow the instructions!
• The products may only be used as intended. Danger may occur if products
are used in another way or in other applications than the intended ones.
• The installation may only be performed by qualified personnel with the
required knowledge and the required capabilities!
• When making electrical connections, applicable electrical codes must be
observed in respect to the way the connection is made, as well as, who is
authorized to perform such connection.
• Electrical installations can only be made by authorized personnel!
• Operation outside the specified operation limits is not allowed!
• Operation outside the specified environmental limits is not allowed!
For the operation of height adjustable tables please note:
• Operation of a height adjustable table is only allowed after being instructed
by a person familiar with the product or after thorough study of the
instruction manual!
• Children are not allowed to play with the table!
• When operated, no persons are allowed on the table top!
• Danger of collision! The table must be placed in a way that it can operate
without colliding with any objects like drawers or window sills!
• Danger of injury by squeezing! The table must be placed and operated
so that no person can be squeezed between the table top or other parts of
the table and other objects in the vicinity of the table.
• Kids under the age of 8 and persons with mental or physical disabilities
are only allowed to operate the table if they have been sufficiently
familiarized with the operation of the table and if it is certain, that they will
not be over challenged by the operation of the table!
• Use of the table is only permitted in closed buildings where it can be
insured the no water or high humidity can get to the electrical parts!
The controllers are manufactured and tested using the utmost care. Should
there be a problem, please contact our service department.
Design of the table controllers
• Highly efficient switching power supply drives one, two, three or four motor
channels.
• The motor channels are controlled by a powerful processor.
• The processor can be configured to a wide variety of applications by an
easy to use configuration software.
• The aluminum housing provides superior heat dissipation, that’s why in
most applications the cool down time is not determined by the controller
but by the motors connected to the controller.
• Port for the OptoSense Sensor

Controller with OptoSense
Options
The following options can be ordered with the controller
• WiFi Module, the controller will be supplied with an integrated WiFi
module. All table functions can be controlled through WiFi
• BLE module, the controller will be supplied with an integrated BLE module.
All table functions can be controlled through BLE, this can be done e.g. by
a smart phone app. This also is required for the wireless control panel.
• OptoSense option, the controller will be supplied with the OptoSense
sensor and a connector inside the controller for the OptoSense sensor.
This sensor allows the user to control the table by gestures.
• GyroSense Option, the controller will be supplied with an integrated
collision detection sensor.
Delivery contents
The controller will be supplied in bulk packages, these contain the controller only.
The power cable, the motor cables and control panels will be supplied in separate
bulk package boxes. The OptoSense sensors too will be supplied in separate
boxes. Fixing screws are not provided.

Installation of the controllers
Controllers without OptoSense
The controller will be attached to the bottom of the table top by two screws, one
on each fixing point at the ends of the controller. A suitable fastener size is #8
wood screw. The length is determined by the thickness of the table top, however
it should be a minimum of ½ inch. When using other size screws, it is important,
that the shaft of the screw is not wider than the slot in the fixing point and that the
head is not bigger in diameter than 3/8 inch. The torque is determined by the
material of the table top, it is important, that the fixing points at the endcap of the
controller not be deformed!
The controller can also be mounted on the cross bar, in this case the mounting
can be done by M4 metric screws with a spring washer to secure the connection.
Important! When the GyroSense option is used, the controller must be mounted
onto the table top to insure proper operation.
Controller with OptoSense
The controller with OptoSense can only be mounted directly below the table top.
It cannot be mounted onto the cross bar!
The picture shows a cross section
through the controller and the table
top. It can be seen, that the centering
stud of the controller endcap reaches
into hole in the table top to position
the controller.
The picture shows the OptoSense
sensor, what has to be inserted
into the top of the controller
through a hole in the table top.
