4.2 Assembly of the worktop support and cross-beams
Now assemble the two cross-beams and the support elements on both side elements. To do that, use
solely the M8 bolts as per the base drawing! The max. tightening torque for these bolts is 20 Nm.
From the inside, screw
two bolts into the crosshead threads.
4x M8 bolt
From the outside, screw two
bolts into the bracket threads
of the support elements.
Note: Experience has shown that it is better to first loosely preassemble the bolts for the crossbeams and then tighten them in the described sequence.
4.3 Assembly of the desktop
If a CPU holder
should be
integrated into the
system, then please
connect both
interior bolts to the
cross-heads via the
column's head
plate.
Now fasten the desktop to the desk base in accordance with the base drawing. To accomplish that, 6.5
mm holes are provided on the desk frame; they are suitable for ø5.5 to ø6.0 mm bolts. Use all provided
bolting points.

4.4 Assembly of the controller and hand-switch
Now attach the controller and the hand-switch to the desktop. ø5.4 mm are provided on the controller
and ø4.5 mm holes are provide on the hand-switch for that purpose. For the controller, use bolts with a
11
raised or cylindrical head. The tightening torque depends on the desktop material, but should not exceed
*1)
2 Nm.
*1)
The screws are not included in the scope of delivery since they have to be selected depending on the
material and the thickness of the desktop.
4.5 Commissioning
Commissioning includes all jobs that are necessary for electrical height adjustment of the FreeStand
sit/stand desk with the aid of the SMART motor controller. The prerequisites for commissioning are:
• The desk base has been completely assembled as per 4.1 – 4.3
• The SMART motor controller and the hand-switch are assembled (as explained in Section 4.4)
Danger: Only expert/authorised personnel are allowed to commission the motor controller!
Expert/Authorised personnel have completed the required electrotechnical apprenticeship and are
familiar with these operating instructions.
Attention: Before assembly and commissioning of the FreeStand sit/stand desk, make sure the
product is acclimatised for the temperature and relative humidity values stated in the technical
data!
4.5.1 Connections to the SMART motor controller
12
4.5.2 Procedure during commissioning
Attention: Plug in the power supply cable/mains cable only after all other electrical connections
have been made! (All motors, the hand-switch and possibly additional accessories are connected
to the controller.)
To commission the FreeStand sit/stand desk, proceed as follows:
4.5.3 Connect the drives
Make sure that the connection cables of the drives reach from both sides up to the corresponding
controller connection. For extremely long desks, it might be necessary to assemble the controller offcentre. For especially large desks, if necessary use an extension cable for the connection cable of the
drives.
Connect the drives of the side panels and the controller using the motor cable. The plug connectors on
the 8-pin motor sockets must firmly latch! For controllers with more connections for drives than the
number of drives available, you must start by connecting the (M1) connection. If, for example, only a
drive is connected to the motor controller, the M2 connection remains open.
Note: When inserting the motor cable, the sequence of M1, M2 must be maintained!
13
4.5.4 Connect the hand-switch
Connect the hand-switch to the 7-pin hand-switch socket (HS)
of the controller.
Note: You can choose from a large number of hand-switches that fit the SMART motor controller!
Please ask Oelschläger Metalltechnik for information on the available types!
4.5.5 Connect the power supply cable /mains cable
Attention: Before you plug in the power supply cable, check again
• to see if the mains voltage matches the rating plate of your controller.
• to see if all components are plugged into the correct sockets.
The SMART motor controller is ready for operation as soon as the power supply cable is plugged
in!
Note: Initialisation of the desk base is required the first time the power supply cable is connected
(RESET). This is described in Section 5.
Attention: Use only the supplied mains cable! It is mandatory to provide the SMART motor
controller with a 3-pin mains cable with protective earth.
Attention: Fasten all cables to the desk base or the desktop so they cannot get damaged during
operation.
4.6 Assembly of optional accessories
If you have also ordered an optional cable tray, plug it onto both cross-beams as the last step. Do not
let any cable get jammed in. Route the mains cable left or right out of the cable tray on the side element.
On certain desk versions, assembly of the cable tray is only possible in the upper position of the desk
base. To do that, you must first initialise the desk base!
5 Initialisation / Reset
After assembling or if the desk has been disconnected from the power supply for a long time, malfunctions on
the desk are possible. The same applies if the connection between the drives and the controller was separated.
In these cases, the desk controller has to be initialised.
If the controller expects a reinitialisation, the downward movement of the desk is only possible at reduced
speed. For hand-switch versions with a display, this is indicated in addition by the “Reset LED”. It turns off as
soon as initialisation has been successfully concluded.
14
To initialise, move the desk to the bottom position; to do that, press the down key on the hand-switch until all
drives have reached the lowest position. Press the down key once again and keep it pressed (approx. 5
seconds) until the desk moves slightly down and then back up. Let go of the button only after the desk stops
moving. If you let go of the button too soon, that causes a malfunction on the desk. If this happens by mistake,
you have to repeat the process.
Attention: The top limit stop of the controller is preset. For this reason, use only controllers that
were supplied as suitable for the respective desk base.
Danger: The optionally available corrosion protection is not activated during any reset process.
During this process, always watch out for the possible danger of being crushed.
6 Control
6.1 Normal operation
Use the "up" and "down" buttons to move the desk up or down in the direction of the arrow. The desk stops

Note: The PowerFail detection of the motor controller detects power failures and saves all
relevant data before the voltage drops below a critical level.
In a few exceptional cases, this saving process is not possible, and during the next controller startup, E81 is displayed and the controller clicks three times.
To repair this error, a manual reset is required (see Section 5).
Note: If there is a power failure during the height adjustment or if the mains cable is pulled, a
manual reset might be necessary.
If the error cannot be repaired as described above, pull the mains plug, wait for several minutes and try to
reinitialise the desk!
If the error continues to occur, unplug the desk from the mains and contact customer service.
This error list is suitable for firmware 1.9.14 and higher!
An (optionally) mounted sensor was removed or the connection has
been lost.
Comply with the separate instructions for the sensor!
