A. Test
Do the operational test of the emergency generator system AMM 24-24-00-710-001.
(1) If during the test:
on the upper ECAM display unit:
4. Fault IsolationDo the operational test of the emergency generator system AMM 24-24-00-710-001.
(1) If during the test:
on the upper ECAM display unit:
- the ELEC ESS TR FAULT warning comes into view.
- the line between DC 1 bus and DC ESS bus comes on
- the line between ESS TR and DC ESS bus goes off
Subtask 24-24-00-810-059-A
A. If the test confirms the fault:
On the MCDU, on the SYSTEM REPORT/TEST page of the ELEC system :
Subtask 24-24-00-710-063-A - do a check of the status of the ESS TR voltage.
On the MCDU, on the SYSTEM REPORT/TEST page of the ELEC system :
- reset the ESS TR
or (if the CFDS is not available) in the relay box 103VU : - push the TR RESET pushbutton switch (15PU).
NOTE: To reset the ESS TR correctly, you must energize it.
When you de-energize TR1 or TR2, the ESS TR becomes energized.
(a) If the fault continues: When you de-energize TR1 or TR2, the ESS TR becomes energized.
- replace the TR-ESS [1PE] AMM 24-34-51-000-001 and AMM 24-34-51-400-001.
- replace the TR-ESS [1PE] AMM 24-34-51-000-001 and AMM 24-34-51-400-001.
B. Do the test given in Para. 3.
