loss of TR2,
-
loss of both TRs,
-
loss of DC NORM BUS 1 switching contactor (1PC1) or DC ESS BUS supply contactor (4PC),
-
availability of emergency generator in operation (Ref. 24-24-00). The essential TR is linked to the ECAM system in the same manner as the main TRs (Ref. 24-32-00, P. Block 1).
A.
Reset of the Protection of the TR Before you reset the TR, make sure that the related electrical network supplies its primary winding, in any RESET mode.
(1)
From the panel 103VU To reset the TR protection push TR RST pushbutton switch 15PU located on panel 103 VU.
(2)
Description of the reset procedure The reset procedure must be performed by selecting the SYSTEM REPORT/TEST item on the CFDS menu, then by selecting the TR 3 page from the ELEC page.
(a)
If the reset is effective, the NO FAULT message appears on the MCDU.
(b)
If the reset is impossible:
. the TR 3 message is displayed on the MCDU.
