(2) Battery Capacity Test
The battery capacity test monitors:
-
if the capacity of each EPSU battery is sufficient enough to supply its emergency lights for at least 10 minutes,
-
if the loss of the capacity of each battery, between two
consecutive battery capacity tests, is smaller than 0.40 Ah. The battery capacity test requires up to three hours to be completed.
**ON A/C 001-049, 051-099, 101-105, 151-158, 201-209,
External loads are:
-
the overwing emergency lights,
-
the escape slide lights.
Internal loads are:
-
the cabin emergency lights,
-
the escape hatch-handle lights,
-
the exit location signs,
-
the exit marking signs.
If there is a communication failure between the emergency power-supply units and the programming and test panel 110RH (CIDS), the display of the programming and test panel 110RH (CIDS) shows the message:
-EPSU COMM.
NOTE : For detailed system information refer to 23-73-00.
____
The GND SCAN mode on the programming and test panel 110RH (CIDS) gives the operator information on the status of the emergency power-supply units. After a failure message, the test buttons of the individual emergency power-supply units are pushed. A red LED shows the defective emergency power-supply units or the associated defective loads.

B. Emergency Lighting Batteries The code for the battery capacity test is selected on the programming and test panel 110RH (CIDS) and the display shows the message BATTERY CAPACITY TEST ACTIVE. An electronic test circuit energizes when the TEST EMER LIGHT BAT membrane switch on the programming and test panel 110RH (CIDS) is pushed. The integral light in this membrane switch comes on. The test circuit connects a 28 VDC positive for the emergency power-supply units 10WL thru 13WL control line TEST and completes, at the same time, the circuit for the BAT OK annunciator light. If all batteries have full capacity, the test circuit is complete and the BAT OK annunciator light comes on.
