System description
1.1
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 (with integrated spindle drive)
•
Control unit (control box, manual control switch and power cable)
The housing of the linear unit SLA/SLG is made out of a colorless anodized aluminium profile. The steel pis-
ton pipe is guided in a plastic bushing and is moved by an inline spindle drive. Up to 4 linear units can be
connected to one control box VD SCT4 and be operated synchronously.
The high-performance control box VD SCT is equipped with two or four 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. 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 hydraulic 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.
1.2
Intended purpose use
The lifting system SLA/SLG is used in applications which need ergonomic height adjustable work surfaces.
While mounting the lifting system into a greater system and while operating the system, the specified nor-
mal operation of the entire system is to be complied with. Commissioning is prohibited until the entire sys-
tem complies with the provisions of EG Machinery Directives 2006/42/EG (Machinery Directive).
The system is only to be installed and used indoors in dry conditions.
The operating temperature range is at 0 °C to +40 °C.
The spindle lifting system must not be overloaded. Do not exceed the given maximum lifting load per linear
unit.
The lifting system can be continuously operated for a maximum of 2 minutes. Afterwards a pause of at least
40 minutes needs to be observed before the system can be operated again. To avoid overheating of the sys-
tem a duty cycle of 2/40 (ON/OFF) should be maintained in general.
1.3
Target group and prior knowledge
This operating instruction addresses the following groups of people:
The
commissioning staff
, who installs and commissions the lifting system into a work station, a machine,
ect. For commissioning activities, mechanical and electrical knowledge is prerequisite. Before using the sys-
tem for the first time the operating instruction must be read.
The
end user
controls the complete system via manual control switch and adjusts its height.
Before using the system for the first time the operating instruction must be read.
