Test - Section 32

Preliminary Work: Pneumatic System Equipment (PSE) Control Module
PSE control module voltage supply PSE, ETP test steps 1.0, 2.0
PSE Control Module Test PSE

Data(mbar)
Test Procedure:
Allowable system leakage of
300 mbar vacuum in 1 minute. Permissible deviation <=30 mbar
Allowable leakage of actuators with at
300 mbar vacuum in 1 minute. Permissible deviation <=25 mbar

Special Tools:

A. Entire System

Preparation For Test:
1. Disconnect yellow central locking (CL) pneumatic line from PSE control module.
2. Connect tester to disconnected pneumatic line using connector 202 805 03 44.

IMPORTANT: 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).

Test Step 1.0:

B. Pneumatic line with RTR actuator

Preparation For Test:
1. Disconnect pneumatic line connected to connector F of pneumatic distributor.
2. Connect tester to disconnected pneumatic line using rubber hose, part no. 007 997 61 82.

IMPORTANT: After testing, reconnect prior disconnected pneumatic line using rubber hose part no. 007 997 61 82 to pneumatic distributor.

Parts Required for Test:
1. Rubber hose, 50 mm long 007 997 61 82

Parts Required for Repair:
Rubber hose (as necessary) 007 997 61 82

Test Steps 2.0 & 3.0:

Test Step 4.0:

2. Connect tester to pneumatic connector.

Parts Required for Test:
1. Pneumatic line, 1m long 000 158 14 35
2. Connector, 50 mm long 007 997 61 82
