5 About this product
5.1 Performance description
The test device is designed primarily for use with the control system SY(H)DFEE.
It may, in addition, be used for all SY(H)DFEx systems with 11+PE connector
- possibly with a restricted scope of functions. The device an be plugged like
an extension cable into the incoming cable of the proportional valve VT-DFPx.
All signals from and to the pilot valve can be measured and evaluated at the
measuring sockets (2 mm). This allows quick diagnostics in the case of problems
in conjunction with the pump system.
Generally, the following applications are conceivable:
• The device is used as intermediate adapter and serves exclusively to make signals
measurable that are exchanged between the SY(H)DFEE system and the higher-
level control.
• In addition to the function described above, the device assumes the task of
generating analog command values for pressure and swivel angle. The command
values for swivel angle and pressure are provided via a ten-turn potentiometer
that allows command values of 0 to ca. 120 % to be generated.
Before utilizing this function, make sure that the system is in an operationally
safe condition so that an improper provision of command values will not result
in personal injury of the operator or damage to the machine.

5.2.1 Block diagram
The block diagram is provided on the back of the device.
Fig. 1: Block diagram of the test device VT-PDFE-1-10/V0/0
5.2.2 Electrical connection
The test device is provided with a socket and a cable connector in order to
interconnect it in the supply cable to the VT-DFPx pilot valve of the
SY(H)DFEE pump control system. The mating connector is to be plugged directly
onto the pilot valve of the pump unit, the cable connector is to be connected to
the incoming cable of the plot valve, which was disconnected beforehand. The
connectors cannot be interchanged.
• The pilot valve has not enable input to deliberately enable or disable the control
function of the valve. The control becomes effective as soon as the pilot valve is
supplied with power and the pump is powered, and the command values that are
input are decisive for the operational states of pressure or swivel angle control.

• The contacts on the mating connector must not be exposed to mechanical stress.
This can lead to temporary or permanent damage to the connection between the
mating connector and the plug-in connector.
Fig. 2: Protection of contacts
The test device has no own power source and utilizes the power supply of the pilot
valve for its own energy supply.
Operating the pump systems requires an external power supply as is the case for
normal operation without this test device. Switch UBon the test device allows the
power supply to the pilot valve to be switched on and off. When the power supply
is available and switch UBis set to EIN (ON), the LED next to is lit green thus
signaling that the pilot valve is supplied with voltage.
The test device is not equipped with an electrical protection against overcurrent
(e.g. micro-fuse). This applies to the implemented power supply and the signal
cables. Fuses have to be provided on the system side.
In the event of faults or when any work is to be carried out, the pilot valve can be
disconnected from the power supply by means of switch UB.
CAUTION: In the case of systems with external supply, the safety function, which
swivels the pump from zero stroke when the control valve is de-energized, is not
effective.
▶ Switch also the drive motor of the pump off in the event of a fault!

device to the pilot valve or the pump system. In this case, any connected higher-
level control has no influence on the command value feedforward to the pump
system.
• Position extern (= external control)
With this switch position the command values are fed from the input connector of
the test device directly to the output connector of the device. This means that the
higher-level control provides the command values for the pilot valve or the pump
system, respectively. The test device merely serves as measuring instrument for
all signals.

• Depending on the variant of the pilot valve, the socket “switch TD“ can be a
digital input (“switch TD“ = control signal to the valve/oil volume adjustment)
or also a digital output (feedback from valve to the control “power limitation
active”) (see operating instructions of the relevant DFE system).
Between the individual measuring sockets there must not be any connections.
They might lead to short-circuits, malfunction or other defects!
5.2.5 Indicator lamps
The green LED next to switch UBsignals that the voltage supply is available and
that the switch is switched on. In this case, the connected pilot valve is supplied
with voltage.
Next to the measuring socket “Fehler“ for the error signal, there is an LED that
shows the current state of the error message. The switching signal is issued by the
pilot valve and works according to the logic “low-active”, i.e.
• the signal level 0V(ore more exactly <1 V) means error
• the signal level +24 V (or more exactly >13 V) means no error
5.2.6 Potentiometers
Two ten-turn potentiometers are integrated in the test device for the provision of a
swivel angle command value (αSOLL) and a pressure command value (pSOLL). They
are only activated, if the switch “Sollwertvorgabe“ (command value provision) is
switched to position “intern” (internal).
The adjustment range of the two potentiometers is from 0 V to ca. +12 V. The
desired command values can be exactly set. The applied voltage can be measured
at the two measuring sockets provided underneath (αSOLL and pSOLL / reference M0).

Impermissible operational states due to unplugging of jumpers!
Risk of injury and risk of damage to property due to uncontrolled movements
that result from the fact that no actual pressure value signal is sent to the pump
control.
▶ Never unplug one of the two jumpers during operation.
The jumpers serve to split the actual pressure signal that is fed to the pilot valve
via the central connection cable. The jumpers are included in the scope of delivery
of the test device.
The actual pressure value level (PISTH) is fed to the pilot valve with its own
reference potential (PISTL). The lower pair of measuring sockets is connected with
the connections of the higher-level control. The signal of the pressure transducer
comes from here. The upper pair of sockets is constantly connected to the pilot
valve at the pump unit.
When the jumpers are removed, an actual pressure value signal from another
pressure transducer may be fed forward to the pilot valve.

In this case, the pressure signal must be connected to the upper pair of sockets
(“nach SYDFEE”). It is important that both the signal (pISTH) and the reference
(pISTL) are connected.
For normal operation the two jumpers must always be plugged in.
Exception: When the integrated pressure transducer HM20-2x is used, which is
directly connected to the pilot valve by means of an M12 connection cable, the
jumpers are irrelevant.
If you replace one of the two jumpers by looping in an amperemeter, the output
signal can be measured directly, e.g. in the case of pressure transducers with
current output.
