Section 7 - Alarms
Whenever a 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 RAD. For example, if CHT 2 is at 480,
and redline is 460, the alert would be displayed as 480 HI CHT2. Other
alarm examples are:
2780 HI RPM, 15 LO OIL-PSI, 240 HI OIL-TEMP.
Tapping the CLEAR button extinguishes the alert for ten minutes
whereas holding the CLEAR button turns the alarm off for the remainder
of the flight.
Primary alarm limits for each specific aircraft model are set by JPI
in accordance with the Pilot Operating Handbook and/or TCDS and
are not programmable by the pilot. These typically include some or all
of the following measurements: CHT, CDT, O-T, O-P, F-P, GAL LEFT,
GAL RIGHT, MAP, RPM, FF, IAT, CRB, 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.
Non-primary Alarm Priority
Primary alarms will always have precedence over non-primary alarms.
The typical non-primary alarm priorities are as follows:
Highest ...........................................................................................Lowest
MIN  REM  DIF  CLD  BUS H  BUS L  AMP
