Section 7 - Alarms
Whenever a primary measured parameter falls outside of the
normal allowed operating limits, i.e. goes beyond redline, the main
display will blink an alert icon. This consists of the current digital value
and a flashing red label in the Scanner area and the REDRemote
Annunciate Light. For example, if CHT 2 is at 480, and redline is 460, the
alert would be displayed as CHT2 480
o
F.
Tapping the CLEAR button extinguishes the alert
Primary alarm limits for each specific aircraft model are set by JPI
in accordance with the POH and are not programmable by the pilot.
These typically include some or all of the following measurements: CHT,
CDT, Oil-T, Oil-P, Fuel-P, GAL LEFT, GAL RIGHT, MAP, RPM, Fuel
Flow, and TIT. To view the alarm limits screen, hold button 2 during
power up (or hold both buttons 2 & 3 during normal operation), tap NEXT
until the list is displayed.
The primary functions for your installation are shown on the Primary label
on the back of the instrument and are identical to those specified in the
FAA Approved Airplane Flight Manual/Pilot’s Operating Handbook.
