*CAUTION:
In case of malfunctions during the charging process, the
"CHARGE page" on the EPSI570C is temporarily replaced by the "FLIGHT

minated as well, and the message is accompanied by an aural warning. The
"FLIGHT page" will remain until message acknowledgment (see appendix
9-A1 for details about EPSI570C messages).
In case of battery coolant pump and/or fan malfunction or battery overtem-
perature during charge, the charging power is set to 0 kW and charging pro-
cess is interrupted. In case of other malfunctions the full charge will be com-
pleted. Write down the caution/warning messages presented on EPSI570C
before acknowledging them and before unplugging the charger from the
aircraft charging port.
WARNING:
Do not take o ff if any caution/warning messages appear
during charging phase. Contact CAMO/CAO.
CAUTION:
Make sure that EPSI570C display is returned to normal FLIGHT/
SYSTEM page mode after the charging process is completed successfully.
Do not take o ff if CHARGE page is still active. Try to re-start the system to
correct the problem. If the issue persists, contact CAMO/CAO.
8.5.4 REST CHARGE PROCEDURE
Rest charge is used to prepare the batteries for a period of inactivity. Rest
charge is an option to "full charge", on the charger display. This process will
charge the batteries to a optimum level for aircraft storage (SOC 70-80% at
the end of the rest charge process. SOC range for battery storage is 30-80
%SOC). The procedure should be repeated every 90 days, during storage
period, to maintain the batteries in optimal conditions.
To perform "REST CHARGE" procedure, follow the same procedure as
"FULL CHARGE", but press "REST CHARGE" option at the beginning of the
charging process.
