6 Commissioning
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. 0%...100%
stroke correspond to 20 mA...4 mA.
On commissioning, please check all connections of the hydraulic and electric supply
systems. Commissioning must only be continued after ensuring that all hydraulic and
electric connections have been properly wired.
6.1 Test run
Make sure that there is no explosive atmosphere during the test run and the de-
aeration process!
Prior to the test run, please ensure that the pipes and the hydraulic system have been
cleaned. The operating medium must correspond to the cleanliness grade stated in
Chapter 1. Cleaning and flushing operations essential to the operating medium must
not be performed with the hydraulically connected way valve. Operation of the way
valve with contaminated operating medium is not permitted and may damage the way
valve.
•
Check the line installation, connection and flow direction to and on the way valve.
•
Check the electrical connection.
•
Switch on the oil supply and check the supply pressure.
•
Switch on power supply.
•
Predefine setpoint w = 4 mA and check the reaction of the consumer connected to
output A.
First, due to lacking hydraulic damping, uncontrolled stroke movements of the
consumer connected to output A and B may occur.
If installed in the proper position, the air included escapes and the damping becomes
effective.
