Pneumatic Test Program - Test (RHR)

Preliminary work:
PSE control module voltage supply 23 PSE 1.0, 2.0
PSE Control Module Test 32 PSE

Data (mbar)

Test procedure Permissible deviation
Allowable system leakage of 300 mbar vacuum in 1 minute. 30 mbar
Allowable leakage of actuators with line at 300 mbar vacuum in 1 minute. 25 mbar

Preparation for Test:
1. Provide access to PSE control module (A37), disconnect white RHR pneumatic line with socket from PSE control module.
2. Connect tester to disconnected socket using connector 202 805 03 44.


If an actuator does not operate correctly and no leakage is found, check the respective lines for kinks or blockages.

Parts Required for Test:
1 Connector 202 805 03 44
2 Rubber hose, 50 mm long 007 997 61 82
1 Pneumatic line, 1 m long 000 158 14 35

Note:
The connections on the PSE control module and pneumatic multiple connector are marked with their German acronyms. In other words:
ZV (German) = CL (English),
SRU (German) = MVA (English),
OSL (German) = OSB (English).
