1 Parker chain tension control unit replaced by prop valve driver[edit | edit source]
at the test stand FOK 5.9 we didn't reach the small pressure with the standard chain tension device,
so now we directly control the proportional valve with the analog output without using the Parker control unit,
to do so, we implement an S7 controller, similar to the new chain tension system HAWE,
and control the prop. valve via the DIAGP UKS driver.
No additional settings have to be performend at the DIAGP UKS driver, it work with the factory settings.
The attached manual is in german only, but not needed anyway
