2System description
2.1 General
The basic functionality of a spindle lifting system SL/SK/SM by Ergoswiss AG is the lifting and lowering of
work surfaces, machine parts, profile systems, etc.
An operative spindle lifting System SL/SK/SM consists of a minimum of following components:
→Lifting column SL/SK/SM
→Control box SCT iSMPS
→Hand switch Memory
→Country specific power cable
The lifting column SL/SK/SM consists of two colorless anodized aluminium profiles which are guided with
plastic guides. The inner profile is moved by an inline spindle drive. Up to 4 spindle lifting elements can be
connected to one control box SCT4 iSMPS and be operated synchronously.
The high-performance control box SCTx iSMPS is equipped with two (SCT2) or four (SCT4) motor channels,
which are adjusted synchronously by an encoder converter. Due to the optimised driving comfort, the end
positions are gently approached as low-speed zones up to the standstill. An integrated tilt sensor reacts to
the system tipping and can prevent potentially dangerous situations. Additional functions, such as the syn-
chronisation of two control boxes or the connection of safety strips (squeezing protection) can be used.
With the hand switch Memory the lifting system can be operated comfortably, the work surface will be ad-
justed steplessly in its height.
The current height of the work surface is shown continuously on the display (in cm or inches). In addition,
up to three different memory positions can be saved and approached individually. Errors that occur are also
shown on the display.

When installing and operating the lifting system, the intended use of the entire system must be adhered to.
Commissioning is prohibited until the entire system complies with the provisions of the EC Directives
2006/42/EC (Machinery Directive). For this purpose, it is essential to perform a risk analysis, so that possible
residual hazards can be reacted to (e.g. through constructive measures or through instructions in the oper-
ating instructions and/or through safety indication on the system). In the event of improper use, the liability
of Ergoswiss AG and the general operating permit for the lifting system will expire.

4Initial operation
ATTENTION
Danger of squeezing during height adjustment!
ATTENTION
It must be possible to fully retract the lifting element to its lower block position at any time
(also in the operating state).
If the lifting element cannot retract completely and hits a stop before it reached its lower
block position, the zero position is set incorrectly. This leads to a collision when moving up to
the upper block position.
ATTENTION
The system may only be fully loaded after the initial operation has been completed.
During the initial operation, the lifting system may be loaded with max. 50% of the system
load.
NOTE
During the initial operation, the lifting system drives with half the speed.
1. Keep the buttons and pressed simultaneously to drive the lower block position.
The system moves downwards at half speed. Upward movement is disabled.
2. After reaching the block position, the system will drive out a few millimeters.
Afterwards the control box will emit 3 signal sounds.
3. let go of the buttons and .
After reaching the block position, the lower and the upper position will be stored automatically.
The initial operation is completed.
NOTE
The lower position is 3 mm (0.12’’) higher than the block position. The upper position depends
on the lifting element type, resp. of the control box software.
4.1 Plug detection
The control box can detect whether a lifting element is plugged into the relevant socket.
The control box only recognizes during the lifting movement whether a lifting element has been removed.
After plugging out or replacing a lifting element the system must be reset to synchronize all connected lifting
elements.
4.2 Duty cycle monitoring
The duty cycle monitoring checks the ratio between the operation time and standstill time. To avoid over-
heating of the system a duty cycle of 2/40 (ON/OFF) should be maintained.
The maximum continuous operating time is 2 minutes. Afterwards a pause of at least 40 minutes needs to
be observed before the system can be operated again.

5.6 Deactivating / activating the tilt sensor «S 08»
The control box has an integrated tilt sensor, which is activated by default.
The 0° inclination of the control is initialized during initial operation or reset. If the inclination of the control
exceeds 2.5° (e.g. inclined table), the control box stops the lifting movement.
After triggering the tilt sensor, the system moves back by 10 mm (0.4’’). If the inclination cannot be cor-
rected (e.g. by driving in the opposite direction), a «Reference drive» must be performed.
ATTENTION
The tilt sensor is not a safety element!
There is still a risk of injury before the tilt sensor triggers.
NOTE
In addition to a collision, the tilt sensor can be triggered by various causes. Therefore, the fol-
lowing should be observed:
Install the control box rigidly before initial operation or reset.
So that the inclination of 0° is properly initialized.
After the system is moved, the tilt sensor should be reinitialized
Perform a «Reference drive» (see chapter 5.8).
For mobile applications (e.g. table on castors), the tilt sensor should be deactivated.
This function can be used to deactivate the active tilt sensor or to reactivate the deactivated tilt sensor.
1. Keep the buttons
1
2
and pressed simultaneously for 4 seconds.
The display shows «S 01», while the «S» is blinking.
2. Press the button or until «S 08» is selected.
3. Confirm the selection «S 0» with the button M.
The control gives an acoustic signal to confirm the change;
If the tilt sensor has been deactivated, the control box will emit 3 signal sounds (short-short-long).
When the tilt sensor has been activated, the control box will emit 1 signal sound.
4. If the tilt sensor is activated, the message «E dd» appears.
For the new initialization of the tilt sensor, a «Reference drive» must now be performed.
