SV-BAT-320 Installation
SkyView System Installation Guide – Revision S 9-3
Electrical Connection
Connect the SV-BAT-320 module’s connector to the mating connector on the main display
harness.
Battery Charging
SkyView displays automatically manage their connected battery’s charge level. If it becomes
discharged, simply turning the SkyView display on – when SkyView’s input voltage is higher
than 12.25 volts – will cause the battery to charge. The battery is not charged at lower bus
voltages to prevent discharging the aircraft battery when it is not being charged by the
alternator or other external charging device.
Battery Status Icon
Battery status icon is individual to each display in a SkyView system. One of two icons, or no
icon will be displayed immediately to the left of the clock in the center of the top bar.
No battery icon displayed

No battery has ever been connected to this display or battery status is normal. If a battery is
connected, all of the following are true:
o An Initial Backup Battery Test has been performed.
o The Annual Backup Battery Test is not yet due.
o The last three automatic backup battery self-checks were normal. Backup battery
self-checks are performed automatically every time master power is removed on the
ground (after a flight, for example) while the 30-second “power lost” timer is
counting down.
Needs test

SkyView has determined that the backup battery should be tested using the manually-
actuated Backup Battery Test. This is because:
o It has been one year since the last battery test. See the Detailed Battery Status
Check section below for details about the nature of the anomaly.
o The 30 second automatic battery self-check that is performed when master power is
removed during a normal shutdown did not complete properly at least 3 consecutive
times.
Fault/test failed

A fault has been detected because of one of the following conditions:
o The battery is no longer connected.
o A battery test has failed. See the following sections for more information.
