SV-BAT-320 Backup Battery Installation
SkyView System Installation Guide - Revision AA 9-5
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 SV-BAT-320 Test has been performed.
o The Annual SV-BAT-320 Test is not yet due.
o The last three automatic SV-BAT-320 self-checks were normal. SV-BAT-320 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 Icon
SkyView has determined that the SV-BAT-320 should be tested using the manually-actuated
SV-BAT-320 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 Icon
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.
Detailed Battery Status Check
Enter the Display Hardware Information Page (SETUP MENU > LOCAL DISPLAY SETUP > BATTERY
BACKUP (SV-BAT-320) STATUS to check the status of the battery.
BATTERY CONNECTED (BATTERY DETECTED): YES / NO
o SkyView automatically sets this to yes when a battery is installed.
LAST BATTERY SHUTDOWN:
o NORMAL
o ABNORMAL: The last shutdown of SkyView did not happen normally.
o WEAK BATTERY: SkyView detected a low battery voltage condition when SkyView
was last shut down. The battery may be discharged or may need replacement.
SkyView will annunciate a warning if this happens repeatedly.
