1System description
1.1 General
The basic functionality of a hydraulic lifting system by Ergoswiss AG (motor drive →pump →tubing →
cylinder) is the lifting, lowering and tilting of work surfaces, machine parts, profile systems etc.
All Ergoswiss hydraulic lifting systems with the pump types PA, PB and PF (with woodruff key) can be driven
by the motor drive PXD compact. The motor drive PXD compact consists of a motor PXD, a control box com-
pact-3-eco, a manual control switch Memory, different connection cables and a plastic housing.
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 two to four drives or the connection of safety strips (squeezing protection) can be
used.
With the manual control switch Memory the hydraulic system can be operated comfortably, the work surface
will be adjusted steplessly in its height. The current height of the work surface is continuously shown on the
display (cm or inches). Up to four different memory positions can be stored and approached individually.
1.2 Intended purpose use
The motor drive PXD compact is exclusively intended to control and drive Ergoswiss AG hydraulic lifting sys-
tems. While mounting the lifting system into a greater system and while operating the system, the specified
normal operation of the entire system is to be complied with. Commissioning is prohibited until the entire
system 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 motor drive PXD compact must not be overloaded. Do not exceed the given maximum lifting loads of
the hydraulic lifting systems.
The lifting system can be continuously operated for a maximum of 2 minutes. Afterwards a pause of at least
18 minutes needs to be observed before the system can be operated again. To avoid overheating of the sys-
tem a duty cycle of 2/18 (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 install and commission the motor drive PXD compact and the Ergoswiss AG
hydraulic system as an incomplete assembly into a work station, a machine, ect. For commissioning activi-
ties, mechanical and electrical knowledge is prerequisite. Before using the system for the first time the oper-
ating 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 and understood.

7Safety strip - Squeezing protection
With lifting systems of Ergoswiss AG it is important to make sure that no objects or people are trapped dur-
ing the lifting movement. ->Danger of squeezing
Attach the safety strip to an assumed squeeze zone. If the safety strip gets squeezed while the system
moves, the motor will stop instantly and turn back for one motor turn.
Depending on the combination of systems (hydraulic transmission ratio), the system stops its movement
3mm, 5mm or 10.5mm before the defined end position.
