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 SLA/SLG
→Control box SCT iSMPS 24V
→Hand switch Memory
→Exchangeable battery packet (Exchangeable battery 10A, holder, charging station)
The linear unit SLA/SLG consists of a colorless anodized aluminium profile and a standpipe made of stainless
steel, which is guided in a plastic guide (SLA) or in a bronze bushing (SLG). The standpipe 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 SCT4 iSMPS 24V is equipped with 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.
The control box is powered by the Exchangeable battery 10A. The maximum possible number of lifting cy-
cles depends on the status of the battery-lifespan and the system load. If the exchangeable battery 10A is
discharged, it must be removed from the holder and charged in the charging station.
The state of charge is indicated by four LEDs;
(1st LED = 25 % | 2nd LED = 50 % | 3rd LED = 75 % | 4th LED = 100 %).
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.

2.2.1 General safety instructions
ATTENTION
The safety instructions must be paid attention to! If the system is operated improperly or not
in accordance with the intended use, there may be a risk to persons and property!
The lifting system may be used if:
→it is located in closed rooms, in a dry and non-explosive environment.
→the ambient temperature is between +10 °C and +40 °C.
→the relative humidity range is between 30% and 70% (non-condensing).
→there are no strong electromagnetic fields nearby.
→This device can be used by children aged 8 and over and by persons with reduced physical, sensory or
mental abilities or lack of experience and knowledge if they are supervised or have been instructed in
the safe use of the device and the resulting dangers to understand.
The lifting system must not be:
→operated outside of the performance data (max. tensile, compressive, bending moment loads).
→subjected to impulse, impact and impact forces (e.g. setting down loads).
→operated with an incorrect mains voltage! Adhere to the type plate of the control box!
→designed for continuous operation (below the duty cycle ratio of 1/9).
→operated on unstable or sloping ground.
→operated with impermissible or non-designated components.
(e.g. different types of lifting elements; replacement of the control (control software))
→operated with damaged components.
→opened, reworked or rebuilt.
→operated if the power cable is not freely accessible. Disconnect the power cord in the event of a fault.
→Children must not play with the device. Cleaning and user maintenance shall not be made by children
without supervision.
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.
2.3 Target group and prior knowledge
Before installing and operating the lifting system, this operating instruction must be read and understood.
The manual must be kept in close proximity to the system for future reference.
This operating instruction addresses the following groups of people:
The manufacturer of the overall system who integrates this lifting system into an overall system and
integrates these operating instructions into the operating instructions for the overall system.
The commissioning personnel who install the lifting system in a workplace, a machine, etc. and put it
into operation. For commissioning basic mechanical and electrical knowledge are required.

2.4 Handling the Lithium-Ion Battery Pack
The exchangeable battery belongs to the class of portable batteries. As a rule, it works smoothly and
maintenance-free. At the end of its lifetime, the power becomes smaller and the exchangeable battery
should then be replaced.
Since the actual battery cells are surrounded by a plastic housing that also contains the charging electronics,
no changes to them can be detected from the outside. The housing also provides additional protection
against potentially leaked battery cells.
Disused exchangeable batteries, as well as old batteries made of power tools, garden tools and household
appliances (e.g. vacuum cleaner robots) are taken back by municipal collection points.
ATTENTION
Do not open the housing to remove the battery cells before disposal!
Don't try to replace used battery cells with new ones!
If the housing of the exchangeable battery is damaged in such a way, that damage to the contained battery
cells cannot be ruled out, it should be disposed of immediately. Preferably at the recycling centre and as a
precaution in such a way, that it can be received by employees. Talk to the specialist staff and point out the
damage.
Storage
Under no circumstances should you store the exchangeable battery in the refrigerator or water and not ex-
pose it to moisture. The storage temperature should be between 0 – 40 °C
(32 – 104 °F) , whereby lower
temperatures are preferable. Due to self-discharge, recharging is required every 3 months.
Transport / Shipping
Lithium-ion batteries are classified as "dangerous goods" in international transport law. Thus, the regulations
for the transport of dangerous goods are relevant for them.
The following rules apply to the modes of transport:
•Road: ADR
Accord européen relatif au transport international des marchandises Dangereuses par Route.
(European Agreement on the International Carriage of Dangerous Goods by Road)
•Rail: RID
Règlement concernant le transport internaional ferr viare de marchandises Dangereuses
(Regulation on the international carriage of dangerous goods by rail)
•Sea freight: IMDG Code
International Maritime Code for Dangerous Goods
•Air freight: IATA DGR
International Air Transport Association Dangerous Goods Regulations

Load
During charging, the LEDs (power indicator) flash
(1. LED = 25 % | 2. LED = 50 % | 3. LED = 75 % | 4. LED = 100 %).
Reload
The battery is self-discharging, therefore recharging is required every
3 months.
A full charge takes a maximum of 6h.
Overload
Charging is automatically terminated when:
- Voltage of the internal battery block is greater than 29 V +/- 3 V, or
- the voltage of a single cell is greater than 4.3 V.
The battery is fully charged when all 4 LEDs are green
Charge low
The battery warns with an acoustic signal if the voltage of the internal
battery block is less than 21 – 22 V.
The battery should then be charged.
Discharge
The battery will automatically shut down if:
- Voltage of internal battery blocks is less than 16.8 V +/-0.5 V, or
- Voltage of individual cells is less than 2.5 V
This state is called "battery discharged".
Further discharge is prevented.
This state is neither audible nor visually displayed and can only be ter-
minated by charging.
Overcurrent shutdown
When the output current reaches values between 14 A and 20 A, the
battery switches off immediately. When the output current is back in
the nominal range, the battery can be used again.
If necessary, this must be cooled and charged.
Short-circuit fuse
If a short circuit occurs at the output, the battery switches off immedi-
ately. When the short circuit has been eliminated, the battery can be
used again.
If necessary, the battery must be loaded

Docking station
The docking station can be connected
to the electricity using the country
specific charging cable.
A brand new battery must first be acti-
vated. This is done simply by plugging
the battery into the docking station.
After approx. 10 seconds, the
power/charging indicator starts to light
up green and the battery is being
charged.
The charge status of the exchangable
battery can be checked using the 4
LEDs of power/charging indicator indi-
cator on the battery.
To check the charging status, press the
test button to the right of the LEDs.
From right to left the LEDs show 25 %,
50 %, 75 % and 100 % of charge.
Only use the battery when it is fully
(100%) charged.

ATTENTION
Der Akkupack darf nur mit der mitgelieferten Docking Station geladen werden!
Nur diese gewährleistet eine ausreichende Sicherheit.
The exchangable battery may only be charged with the included docking station!
This is the only way to ensure adequate security.

3.3 Mounting instructions Control box
ATTENTION
During mounting of the control box the power cable needs to be disconnected from the
mains!
NOTE
The control box has an integrated tilting sensor as standard. To ensure the smooth normal
operation, the control box must be fixed rigidly to the system before initial commissioning.
(e.g. below the tabletop)
Mounting the control box at the bottom of a tabletop:
1. Place the control box to the desired location and mark the drill holes with a pen.
2. Pre-drill 3 holes (Ø 2.5 mm / 0.1’’) .
Be careful not to drill through the table top!
3. Mount the control box with 3 screws.
(e.g.: Button head screw DIN 7981-C, Ø 3.9 mm
(0.15”) , head-Ø 7.5 mm ( 0.33’’)) .
NOTE
When tightening the screws do not exceed a maximum torque of 2 Nm
(1.5 lbf⋅ft) !
NOTE
The motor cable has a length of 1’800 mm (71’’) . If needed, up to 5 motor extension cables
can be connected. They have a length of 1’200 mm
(47’’) each.

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 1/9 (ON/OFF) should be maintained.
The maximum continuous operating time is 1 minutes. Afterwards a pause of at least 9 minutes needs to be
observed before the system can be operated again.
