2System description
2.1 General
The basic functionality of a spindle lifting system SF by Ergoswiss AG is the lifting and lowering of work sur-
faces, machine parts, profile systems, etc.
An operative spindle lifting System SF consists of a minimum of following components:
→Lifting column SF
→Control box Compact-3-eco
→Hand switch Memory
→Country specific power cable
The lifting column SF 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 3 spindle lifting columns can be con-
nected to one control box compact-3-eco and be operated synchronously.
The intelligent control box compact-3-eco is equipped with a highly efficient switched-mode power supply
(SMPS) and a monitoring software (overload, duty cycle, overheat). Due to the optimised driving comfort,
the end positions are gently approached as low-speed zones up to the standstill. Additional functions, such
as the synchronisation of 2 to 4 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 4 different memory positions can be saved and approached individually.

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 button pressed to drive to the lower block position.
The system moves downwards at half speed. Upward movement is disabled.
2. After reaching the block position, let go of the button .
The control box will give a click sound and the system will drive out a few millimeters.
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 5 mm (0.2’’) 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. In addition, the
control box detects whether a lifting element has been replaced.
If a lifting element is missing or if it is replaced, the control box will click three times.
After plugging out 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 Restore to factory settings – Factory reset «S 0»
ATTENTION
Before restoring to factory settings, it must be ensured that:
- the lifting element can retract completely.
- the lifting system is loaded with a maximum of 50% of the maximum allowed system load.
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.
NOTE
During restoring to the factory settings, the lifting system drives with half the speed.
When restoring the factory settings, the entire system is newly set up again.
All settings such as Memory positions or End positions are lost.
1. If possible: Drive to lowest position
This saves time because the system only drives with half speed when doing a reset.
2. Press the buttons

ATTENTION
Before the reset, it must be ensured that:
- the lifting element can retract completely.
- the lifting system is loaded with a maximum of 50% of the maximum allowed system load.
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 up-per block position.
NOTE
During restoring to the factory settings, the lifting system drives with half the speed.
1. Drive the system to the programmed lowest position.
2. Keep the button pressed for 5 seconds («Long Key Down»).
The system moves downwards to the lower block position and resets itself like during the initial opera-

7Synchronous operation of 2, 3 or 4 control boxes
7.1 Cable connections
Up to three lifting elements can be connected to one control box Compact-3-eco.
By cascading multiple control boxes they can be controlled simultaneously with just one hand switch. The
control boxes can be connected using the SYNC-2 cable (124.00088) or the SYNC-4 cable (124.00089).
SYNC-2 Cable
With the SYNC-2 cable two control boxes Compact can be
connected and synchronised.
The length of the SYNC-2 cable is 550 mm (21.7’’) .
The SYNC cable cannot be extended. If necessary, the motor
cables can be extended!
NOTE
Always do reset before disconnecting!
Disconnect plug carefully Risk of rip-out!
SYNC-4 Cable
With the SYNC-4 cable 2, 3 or 4 control boxes Compact can
be connected and synchronised.
The length of SYNC-4 cable is 1’800 mm (71’’) .
Two connected SYNC-4 cables have a length of 2.0 m (78.7’’) .
Each control box needs one SYNC-4 cable.
The SYNC cable cannot be extended. If necessary, the motor
cables can be extended!
The SYNC-4 cables of each control box are to be connected to
each other.

7.2 Commissioning the synchronized systems
1. Connect the motor cables to the control box. (Automatic plug detection on all motor sockets)
2. Connect the control boxes using the SYNC-2 cable for two control boxes, or the SYNC-4 cable for 2, 3 or
4 control boxes.
3. Only one hand switch is necessary. The control box with the hand switch is the master control box. All
other control boxes are subordinated.
Connect hand switch to desired control box.
4. Connect power cable to the mains.
(Click sound of all control boxes ready for initial operation)
5. Carry out the initial operation according to chapter 4.
ATTENTION
The SYNC cable must be connected to the control box before the control box is connected to
the mains.
If the SYNC cables are connected afterwards, they will not be recognised by the control box
and only one control box works, which can lead to jamming of the entire system!
NOTE
When disconnecting the SYNC cable uncarefully, the plug can be ripped out of the print
platine!
