11.3 Relay / Function Test
Function: Depending on the controller version various outputs can be tested. This is not only a
relay test, but a function test by means of which the hydraulic components are tested.
The partially compulsory sequence of the switching procedures is considered.
After selecting the test function the relevant relays can be switched one by one by
pressing the rotary pushbutton in the specified switching sequence.
