Main Battery Voltage Monitoring

If the main battery voltage reaches LB1, the system issues a warning buzzer. If this warning buzzer

sounds, either start recharging the battery or replace it with a fully charged battery as soon as

possible. If one of these measures is not taken within ten minutes, the system will forcibly turn off

the power for safety. The following diagram shows the main battery voltage against the time axis.

(a) If the main battery voltage reaches LB1, the low battery voltage warning alarm sounds.

(b) Unless the main battery is either replaced or recharged within ten minutes, the system power is

automatically turned off to protect the data.

power to the main unit (critical suspend).

(d) If the main battery voltage drops below LB0, the main unit power cannot be turned on even if

the power switch is pressed.

(e) If the main unit is mounted on the I/O Box or connected to the AC adaptor, charging of the

battery is initiated and the main battery voltage will gradually increase.

(f) Once the main battery voltage has been recharged to an operable level, it is possible to turn on

the power to the main unit.

For information about the method used to replace the main battery refer to Chapter 2.2.6 “
