-Centralized Fault Display Interface Unit (CFDIU),
-two Multipurpose Control and Display Units (MCDU).
BCL's are type 2 systems, i.e. they are connected to the CFDIU with:
-a discrete input used to initiate a test from CFDS,
-an ARINC 429 output bus.
TR's are type 3 systems, i.e. they are connected to the CFDIU with 2
discrete links:
- one of them used to send a ground signal to CFDIU in case of TR FAULT.
-the other used for the reset from CFDIU.

Subtask 24-30-00-040-050
A. Do a charging cycle of the battery 1 (2) related to the BCL 1 (2) in operation.
(1) If:
-
the failure of the BCL 1(2) occurred during the last flight and the time the aircraft was on ground was not more than 3 hours, or
-
the BCL 1(2) did not operate during the last flight and the time the aircraft was on ground was not more than 3 hours:
(a)
on the ECAM control panel:
-push the ELEC key to get the ELEC system page.
(b)
In the cockpit, on the ELEC panel 35VU:
-push the related BAT 1 (2) pushbutton switch to start the charging cycle of the battery 1 (2).
(c)
On the lower ECAM display unit:
-
the green line between the BAT 1 (2) indication and the DC BAT busbar indication comes into view. The arrow points to the BAT 1 (2) indication,
-
the related parameter indications (voltage and current) come into view green.
(d)
On the ELEC system page, make sure that the ground power-unit voltage stays above 114VAC during the charge.
