Accutorr 7 Operator’s Manual 15 - 1
15 Battery
15.1 Overview
The monitor is designed to operate from battery power when AC power is interrupted.
The battery is charged whenever the monitor is connected to an AC power source
regardless of whether or not the monitor is turned on. Since no external battery charger
is supplied, the battery can only be charged inside the monitor. In case of power failure,
the equipment automatically runs from the battery.
The battery is to be used if the integrity of the protective earth conductor or the
protective earthing system in the installation is in doubt.
• It is recommended to always install a fully charged battery in the monitor to
ensure normal monitoring in case of accidental power failure.
The on-screen battery symbol indicates the battery status as follows:
â– Indicates that the battery is fully charged. The solid portion represents the
current charge level of the battery in proportion to its maximum charge level.
â– Indicates that the battery has a low charge level and needs to be charged.
â– Indicates that the battery is almost depleted and needs to be charged
immediately. Otherwise, the monitor automatically shuts down.
â– Indicates that no battery is installed.
The capacity of the battery is limited. When the battery is low, the technical alarm area
displays [Low Battery], the alarm light flashes, and the monitor produces an alarm
sound.
If the battery is depleted, the battery symbol on the screen flashes, the technical alarm
area displays [Battery Depleted], the alarm light flashes, and the monitor produces
alarm sound. Connect the equipment to AC mains to run the equipment and charge the
battery. Otherwise the monitor will shut down.
• Charge the battery or replace the battery with a fully charged battery when
the monitor gives the alarm [Low Battery] or [Battery Depleted]. The device
will not allow the user to enter Standby mode when the battery power is low.
