1.10 Dimensions controller for battery-operation LTCB For the differing measurements of the OptoSense option see “controller for mains connection” 1.11 Options The following options can be ordered with the controller • WiFi module: the controller will be supplied with an integrated WiFi module.
2 Installation of the controllers 2.1 Controllers without OptoSense The controller will be attached to the bottom of the tabletop by two screws, one on each fixing point at the ends of the controller. A suitable fastener size is #8 wood screw.
2.3 Controller with OptoSense The picture shows the OptoSense sensor which has to be inserted into the top of the controller through a hole in the tabletop. The picture shows a cross section through controller tabletop. It can be seen, that the centering stud of the controller endcap reaches into the hole in the tabletop to position the controller.
maximum of 90° until it can be inserted with little force into the controller. Once the edge of the transparent cover of the sensor reaches the table top the force must be increased up to about 200N to insert the cover into the hole. The cover must be pressed in until the rim of the cover reaches the surface of the tabletop.
2.5.2 Oval control panels For the installation of the oval control panels an appropriate pocket and a ½” hole have to be machined into the tabletop. The cable will be put through the hole from the top, then the control panel will be pressed from the top into the pocket. While inserting the control panel make sure the control panel will not be pressed too hard, if required the size of the pocket has to be adjusted.
Cutout for control panels with six buttons IC series Cross section table cut-out 2.6 Electrical connection The picture shows the output connection side of the controller. • 1 Motor 1 • 2 Motor 2 • 3 Motor 3 (LTC 383 and LTC 384) •...
2.6.1 Connectable Motors The controllers are designed to be connected to motors with the following ratings. Besides the suitable rating, it is required that the motor connectors correspond to the pin assignment shown under “Pin assignment for motors” below. Nominal voltage 24 V Maximum current Number of hall sensors (90°)
Motor connection 2.7 Connection of the motors The motors must have an 8 pole Molex plug and must comply with the requirements described under “Connectable motors” The motors may then be plugged into the connectors of the controller in the order shown on the controller cover.
Attention! It is not possible to connect two control panels with height indication or two control panels without height indication to one controller. This will result in a malfunction of the controller. Should more control panels be required see next step.
2.9.1 Connection The wireless keyboard LM4RW can be connected to any controller that is equipped with a BLE Module. Make sure the BLE module in the controller is activated through the Wizard or the LD control panel before using the keyboard. In addition to the wireless control panel, other control panels can be connected to the controller.
To connect another keyboard or to connect the keyboard to another controller, perform the described pairing procedure again with a different keyboard or a different controller. When a keyboard is paired with more controllers, all controllers will start moving, once they get the command by the keyboard. However, while the controllers start and stop simultaneously, they will not be synchronized.
Attention: Make sure the power cable will be placed in a way what provides stain relief to the plug so that the plug cannot be pulled out of the controller. 2.11 Connection LTCD The controllers of the LTCD series are equipped with a 4-cored connection cable. Blue: ground Brown:...
The battery can be charged inside or outside of the controller. Therefore, the battery charger has to be plugged into the charging socket and connected to the mains. While charging the first LED is blinking until the charging status exceeds 25 %, then the first LED is lighted permanently and the second LED is blinking.
3 Start of operation After mounting the controller and the control panels, making all electrical connections and making sure that the right parameter set is loaded to the controller, the table can be put into service. Upon power up, the table makes a reference run to acquire the reference position.
To sense such a change in position, the GyroSense equipped controller must be mounted to the tabletop. Placing the controller in the crossbar will not work! Attention: Even if the system will sense reliably even very small unusual movements of the table, it cannot be 100% insured that this will avoid injuries of the table users and persons around the table as also the mechanic of the table and the environment of the table can cause such injuries! This is why no liability can be accepted for personal injury or any other damage! It is the user’s sole...
For each type of collision detection there is a percentage set in the controller, by which the limit value of the sensitivity is being changed. When changing the sensitivity level from 2 to 3, each limit value is being multiplied by the according percentage and added to the limit value, when switching from 3 to 4 it is added once again.
3.6 Determining the stroke by the reference run When the stroke detection is activated in the Wizard, a reference run will not only establish the reference position but will also determine the stroke of the drive. To enable this, the drives must be equipped with a limit switch at bottom and at the top, or the drive must support, that the bottom and top mechanical stop can be hit to enable the controller to determine the end position without limit switch.
Alternatively, the controller can be set through the Wizard in a way, that the movement continues with the speed set for the safety zone when the set height is reached. In this case the button doesn’t have to be pushed again. Through P35 the starting point of the safety zone can be set.

4.4 Control panels with height indication Control panels with height indication show the actual height of the tabletop in centimeters or inches depending on the configuration. 4.5 Controlling the controller by OptoSense • Hold your hand about 5 cm or 2 inches on top of the OptoSense sensing element •...
4.6 Configuration of the controller through the “LM” control panels (control panels without height indication) In the Wizard can be chosen whether the menu is accessible through the control panel or not. If not, the user is only able to set the memory position and to request a reference run.
Attention: The top and lower positions must keep a minimum distance so that the table can still move after the new limits have been adjusted. This minimum distance is defined in the parameter set entered into the controller. Saving a new upper or lower limit is not possible if the minimum distance is not maintained.

4.7 Configuration of the controller through the “LD” control panels (with height indication) In the Wizard can be chosen whether the menu is accessible through the control panel or not. If not, the user is only able to set the memory positions and to request a reference run.
• By using the arrow keys the indication can be toggled from “0” to “1” and from “1” to “0”. Once the right selection is made push the memory key “one” to confirm the selection, a sound will confirm that the setting is stored, the display will go back to normal operation and indicate the height •...
4.7.4.2 Deleting the user height limits • Move the tabletop by use of the arrow keys to the minimum or maximum height (Keep the “up” or the “down” key pressed until the table stops moving) • Press the “up” arrow key 4 times quickly one after another •...
• Press the memory key “one” shortly to store the selected limit, the successful storage of the user position will be confirmed by the sound displayed Attention: The top and lower limits must keep a minimum distance so that the table can still move after the new limits have been adjusted.
If for example the upper user height limit shall be decreased in a way, that the minimum stroke is undercut, the lower user height limit has to be decreased as well, so the minimum stroke is ensured again. 4.7.7 Changing the sensitivity of the collision detection by the “LD” control panels Over time the movement of the table may change due to wear or change of the lubrication properties.
reference is recalibrated, the table is leveled, and the height indication is correct. If a power failure occurs or the mains plug is being pulled out while traveling, the controller will go to reference mode automatically. 4.7.9 Adjusting direction of the reference run If a reference run downwards isn’t possible, an upwards reference run can be set.
