Task
Install the device in accordance with the circuit diagram. Ensure it is wired cor-
rectly and that the signals are well shielded.
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 via the
USB interface and the programming device ULA-310. Please see the WPC-
300 program documentation for how to set up communication.
Caution:
The communication works in a HALF DUPLEX process.
Further commissioning and diagnosis are supported by the operating software.
Alternatively, the set-up can be done by the internal parameter selector and the
UP and DOWN buttons.
Parameterize now (with the help of the system redundancy and the connection
diagram) the following parameters:
The ANALOGUE INPUT, the output CURRENT and the typical valve parame-
ter 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... 2.5 A. In the current state it should show around 0 A.
The valve current can also be monitored in the WPC program.
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 is always active when power supply exists. The
output current to the valve will follow the input signal proportionally.
Settings like ramp time or dead band compensation can now be done.
