Page 17: Function
For way valve operation, an electric and a hydraulic auxiliary energy are required. All electric controllers and connections necessary for the way valve operation are integrated in the Voith control magnet (VRM). The control loop parameters and the parameters to scale the position of the piston rod are set via potentiometers on the VRM. - Page 18 WSR-D80112-S Design and Functioning Limitation of maximum value In case of incorrect connection of the setpoint, e.g. by unintentional connection of 24 VDC to the plus-port of the setpoint input, the setpoint current is limited to an uncritical value by means of an overload protector integrated in the VRM, thus protecting the way valve control against damage.

Page 23: Commissioning
6 Commissioning NOTICE Prior to delivery, the way valve has been tested and adjusted at Voith Turbo GmbH & Co. KG. The settings are documented in the supplied test report. It must be ensured that the signal of the position pickup coming from the cylinder is falling, i.e. - Page 24 WSR-D80112-S Commissioning How to de-aerate the hydraulic system Operate the way valve for a period of min. 10 minutes at a setpoint sine rhythm (4 mA to 20 mA). Alternatively, it is possible to also run the setpoint via a ramp. Should it not be possible to specify a setpoint sine rhythm, connect a setpoint source directly to the way valve.

Page 26: Potentiometer Effect
WSR-D80112-S Commissioning 6.2.1 Potentiometer effect Potentiometer Description The 0% position of the piston rod of the hydraulic cylinder can be adjusted by means of the X0 potentiometer. By turning the potentiometer clockwise, the piston rod moves towards increasing stroke. The 100% position of the piston rod of the hydraulic cylinder can be adjusted by means of the X1 potentiometer. -
