7.6 CONNECTING THE SYDFE1 CONTROL SYSTEM
ELECTRICALLY
The machine or system manufacturer is responsible for setting up the electrical
control.
With electrically controlled SYDFE1 control systems, the electrical control must be
connected according to the circuit diagram of the machine or system manufacturer.
The VT 5041-3X control electronics is connected using a 32-pin female multipoint
connector and can be installed in a Euro rack or in a card holder from Rexroth
(VT3002 according to RE 29928).
CAUTION! Live installation!
Risk of injury when plugging or unplugging connectors under voltage.
▶ Before carrying out any installation work or plugging or unplugging connectors
from the product, disconnect the device from the power supply or the voltage
source or de-energize it reliably. Damage to the control system caused by
incorrect installation is not covered by the warranty!
1. Disconnect the relevant system part from the power supply.
2. Connect the SYDFE1 control system electrically (24 V).

Cabling of electronic components

Generally, the following is valid:
– Use low-capacitance cables according to the safety regulations of the German
VDE or national electrical safety regulations of your country. Whenever
possible, establish the cable connections without intermediate terminals!
– Select only cables that have the actually required number of wires (avoid
superfluous wires).
– The installation of electromagnetic sources of interference, e.g. unearthed
contactors, in the direct vicinity of the pilot valve is not permitted.
– Installing power cables in the vicinity of the control electronics is not
permitted.
– No switches or relay contacts may be installed in the electrical connections
between the pump/proportional valve and control electronics, because
breaking of a connection results in fault messages or malfunctions. Whenever
possible, do without intermediate terminal points or reduce their number to a
minimum.
– Cables of inductive position transducers, swivel angle sensors and of the
pressure transducer must be shielded. Connect the shield only on one side
to the control electronics (see Fig. 22). Never connect the shield to the valve,
pump or pressure transducer.
