2System description
2.1 General
The basic functionality of a spindle lifting system SLA/SLG by Ergoswiss AG is the lifting and lowering of
work surfaces, machine parts, profile systems, etc.
An operative spindle lifting System SLA/SLG consists of a minimum of following components:
•Linear unit
•Control box
•Manual control switch Memory
•Power cable
The housing of the linear unit SLA/SLG is made of a colorless anodized aluminum profile. The steel piston
pipe is guided in a plastic bushing (SLA) or in a bronze bushing (SLG) and is moved by an inline spindle
drive. Up to 4 linear units can be connected to one control box SCT4 iSMPS and be operated synchronously.
The high-performance control box SCT4 iSMPS is equipped with two or four motor channels, which are ad-
justed 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 tip-
ping and can prevent potentially dangerous situations. Additional functions, such as the synchronisation of
two control boxes or the connection of safety strips (squeezing protection) can be used.
With the separately available manual control switch Memory the spindle system can be operated comforta-
bly, the work surface will be adjusted steplessly in its height. The current height of the work surface is con-
tinuously shown on the display (cm or inches). Up to three different memory positions can be stored and
approached individually. Errors that occur are also shown on the display.

4Initial operation
ATTENTION
Danger of squeezing during height adjustment
ATTENTION
The lowest block position must always be reachable.
The lifting element is not allowed to hit a stop before it reached its lowest block position.
Otherwise the reference will be stored at a wrong height. This would lead to a collision when
driving up to the mechanical block.
ATTENTION
The system can be fully loaded after the initial operation has been completed. During initial
operation, the lifting element can be loaded with a maximum of 60 kg (130 lbs).
NOTE
During the initial operation, the lifting element drives with half the speed.
1. Keep the buttons and pressed simultaneously to drive to the under block position.
-> The system moves downwards at half speed.
-> Upward movement is disabled.
2. After reaching the block position, let go of the buttons and .
-> The control box will give a signal sound and the system will drive out a few millimeters.
-> After the drive out, control box will give another two signal sounds.
After reaching the block position, the lower and the upper position will be stored automatically. The initial
operation is completed.
(The lower position is 4 mm (0.16’’) higher than the block position. The upper position depends on the lifting
element type, resp. of the control box software.)
4.1 Duty cycle monitoring (ED)
The duty cycle monitoring checks for the operation/hold ratio. To avoid overheating of the system a duty
cycle of 2/18 (ON/OFF) should be maintained.
The maximum continuous operating time is 2 minutes. Afterwards a pause of at least 18 minutes needs to
be observed before the system can be operated again.

5.7 Restore factory settings
ATTENTION
Before restoring the factory settings, it must be ensured that:
- the lifting element can retract completely.
- each lifting element is loaded with less than 60 kg (130 lbs).
NOTE
When restoring the factory settings, the entire system is set up again. All settings such as
memory or Container-stop positions are lost.
1. If possible: Drive to lowest end position
-> This saves time because the system only drives with half speed when doing a reset.
2. If needed, the system can now be rewired
a. Remove the cable from the mains
b. Rewire the system:
More lifting columns, synchronization cables or safety strips can now be connected.
c. Connect the power cable to the mains.
3. Keep the buttons

and pressed simultaneously for 4 s.
-> The display shows «S01», while the S is blinking
4. Press the button or until «S00» is selected.
5. Confirm the selection «S00» with the button M.
-> A signal tone sounds
6. Press the button

5.8 Reset / initialize the end positions
ATTENTION
The lowest block position must always be reachable.
The lifting element is not allowed to hit a stop before it reached its lowest block position.
Otherwise the reference will be stored at a wrong height. This would lead to a collision when
driving up to the mechanical block.
ATTENTION
The system can be fully loaded after the initial operation has been completed. During initial
operation, the lifting element can be loaded with a maximum of 60 kg (130 lbs).
NOTE
During a reset, the lifting element retracts completely and the end position (reference posi-
tion) of the lifting element is redefined.
NOTE
During the initial operation, the lifting element drives with half the speed.
1. If possible: Drive to lowest end position
-> This saves time because the system only drives with half speed when doing a reset.
2. Keep the buttons and pressed simultaneously to drive to the under block position.
-> The system moves downwards at half speed. Upward movement is disabled.
3. After reaching the block position, let go of the buttons and .
-> The control box will give a signal sound and the system will drive out a few millimeters.
-> After the drive out, control box will give another two signal sounds.
The reset is now completed.

5.9 Deactivating /activating the tilt sensor
The control 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 controller stops the lifting movement. After triggering the tilt sensor, the system can be released up-
wards. If this is not possible, a reset according to Chapter 5.8 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 inclination sensor can be triggered by different causes. There-
fore, the following should be observed:
1. Install control rigidly before initial commissioning or reset
→So that the inclination of 0° is properly initialized.
2. After the system is moved, the inclination sensor should be reinitialized
→reset according to chapter 5.8
3. For mobile applications (e.g. table on rollers),
the inclination sensor should be deactivated.
The tilt sensor is deactivated (or activated), when following commands are executed:
1. Keep the buttons
1
2
and pressed simultaneously for 4 s.
-> The display shows «S01», while the S is blinking
2. Press the button or until «S08» is selected.
3. Confirm the selection «S08» with the button M.
-> A signal tone sounds
4. Press the button
1
2
or
3
to leave the menu mode.
5. If the inclination sensor is activated, the message "Edd" appears.
For the new initialization of the tilt sensor, a reset according to chapter 5.8 must
now be performed.
