Commissioning
Prior to delivery, the I/H converter has been tested and adjusted at J.M. Voith SE & Co.
KG │ Division Digital Ventures. The settings are documented in the supplied test report.
Potentiometers X0 and X1 are covered with a cap for protection against unintentional
maladjustment and entry of dirt.
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 (Chapter 5).

Test Run
How to de-aerate the hydraulic system
Make sure that there is no explosive atmosphere during the test run and the de-aeration
process!
•
Switch on the power supply.
•
Switch on the oil supply and check the supply pressure P.
•
Enter setpoint w = 0 mA.
•
After 5 minutes, switch on setpoint w = 4 mA.
•
Operate the I/H converter for a period of min. 10 minutes at a setpoint sine rhythm (4
mA to 20 mA). Alternatively, it is possible to run the setpoint via a ramp (attention:
longer de-aeration time!). If it is not possible to specify a setpoint sine rhythm, a setpoint
w = 20 mA can be directly connected and disconnected via a setpoint source.
During the test run, check all hydraulic connections for leaks. In case of leaks, immediately
switch off the hydraulic supply system and remedy the leakage.
6.2
Parameter setting
Due to unintentional maladjustment of the parameters or changed operating conditions,
one or both parameters may have to be readjusted. We recommend documenting the
adjustment of the parameters as well as the set values.
The parameters are adjusted by means of potentiometers X
0
and X
1
. For position of
potentiometers, please see Chapter 10.
Prior to the test run, please ensure that the pipes and the hydraulic system have been
cleaned. Cleanliness of 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 I/H converter hydraulically connected. Operation of the
I/H converter with contaminated operating medium is not permitted and may damage
the I/H converter.
During the test run, air pockets in the hydraulic piping system may cause temporary
pressure variations at output pressure PA. In such cases, please de-aerate the system.
