PTP - Pneumatic Test Program

Preliminary work:
PSE control module voltage supply 1.0 - 4.0
PSE Control Module Test PTP - Pneumatic Test Program

Preparation for test:
1. Review Connection and Use of Test Equipment,
2. Review Component Locations, Connection of Components and Pneumatic Test Program.

DATA (mbar)
Test procedure
Allowable system leakage of 300 mbar vacuum in 1 minute,
Permissible deviation: <= 30 mbar

Allowable leakage of actuators with line 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.

NOTE: 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 05 44
2 Rubber hose, 50 mm long 007 997 61 82
1 Pneumatic line, 1 m long 000 158 14 55

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 Steps 1.0:

B. Pneumatic Line With RTR Actuator

Preparation for test:
