V2500 BLEED VALVE TESTER P/N TEE90 SHORT INFORMATION FROM OPERATION MANUAL Get Acces (1) Open the fan cowls (Ref. AMM Procedures) Set-up Procedure A. Disconnect the air tube from the Solenoid Valve (Ref. AMM Procedures) Disconnect the electrical connector from the solenoid valve Install the RMS Bleed Valve Tester Tee90 (1) Install the vacuum line (a) Install the vacuum line fixture (10) on to the pressure line connection (8) and the servo vent (11) (2) Install the pressure line (a) Install the pressure line union (9) to the pressure line connection (8) (b) TORQUE the pressure line uinion (9) between 204 and 221 lbf. in (2.30 and 2.49 m.daN): Make sure the vacuum fixture (10) seals down over the servo vent (11). (3) Connect the electrical connector (12) to the applicable solenoid valve. Test the Bleed Valve (1) Make sure all switches on the TEE90 are in OFF position (2) Connect Power Cable to power source (3) Switch tester ON (4) Wait (approx. 1 min.) until the pressure gage reads 30 psi (2.07 ± 0.05 bar) and the vacuum gage reads 0.5 ± 0.05 bar (7.25 psi) (5) Turn the solinoid switch to the ON position (6) Turn the pressure air supply switch to the ON position (7) Turn the vacuum air supply switch to the ON position, listen, and you should immediately hear the bleed valve close. NOTE: Step 8 should be carried out immediately after step 7! (8) Turn the solinoid switch to the OFF position and the bleed valve should bang open. NOTE: The sound of the bleed valve opening is louder than when it closes ! TROUBLESHOOTING: If the Bleed Valve does not operate correctly, replace either the Bleed Valve or the Solenoid Valve. Ref. to AMM for correct procedures. Disconnect the Bleed Valve Tester TEE90 (1) Switch pressure, vacuum and solenoid switches to OFF (2) Switch main power switches to OFF (3) Disconnect the electrical connector (12) from the solenoid valve (4) Disconnect the pressure line (a) Disconnect the pressure line union (9) from the pressure line connection (8) (5) Disconnect the vacuum line (a) Disconnect the vacuum line fixture (10) from the pressure line connection (8) and the servo vent. Return engine to normal operating condition. Ref. to AMM System under series production Dynamic Test Systems
