Task
Install the device in accordance with the circuit diagram. Ensure it is wired cor-
rectly and that the signals are well shielded. The device must be installed in a
protective housing (control cabinet or similar).
Ensure that no unwanted movement is possible in the drive (e. g. switch off the
hydraulics). Connect an ammeter and check the current consumed by the de-
vice. If it is higher than specified, there is an error in the wiring. Switch the de-
vice off immediately and check the wiring.
Once the power input is correct the PC (notebook) should be connected to the
serial interface. Please see the WPC-300 program documentation for how to
set up communication.
The operating software supports further commissioning and diagnosis.
Parameterize now (with the help of the system redundancy and the connection
diagram) the following parameters:
The NOMINAL PRESSURE for the ANALOGUE INPUTS. See specifications of
the system and the sensors.
The output CURRENT and the typical valve parameter DITHER and MIN/MAX.
Pre-parameterization is necessary to minimize the risk of an unintentional
movement / pressure.
Check the control signal (output signal). The control signal (solenoid current)
lies in the range of 0... 2,6 A. In the current state it should show around 0 A.
CAUTION! This signal depends on the EOUT setting.
The hydraulics can now be switched on. The module is not yet generating a
signal. Drives should be at a standstill or drift slightly (leave its position at a
slow speed).
CAUTION! The power stage gets activated.
The controller can now be driven by the analogue command value. The feed-
back value is read in and the output signal gets calculated by means of the
control deviation and the parameterization.
Now optimize the settings. The PID parameters have to be adapted depending
on the application.
