V0614, 3.9 

 

5.2.  Testing the valve deflection 

 

Function 

With this test the hydraulic-valve drive circuitry can be tested. Also the hydraulic pressure can 
be tested. To perform this test all the valves must be connected correctly. 
 

Description 

Via the cursor keys or the function keys S1, S2 and S3 you can select the required valve. 
 
The test procedure for valve deflection depends on the type of valves that is installed. On the 
following two pages two different procedures are described. The first procedure is for 
Hoerbiger valves, which are connected directly to the DA-52s. The second procedure must 
be followed when external valve amplifiers are used to control the valves.
