2.16 IO INTERFACE BOARD OPERATION
The IO Interface Board Annunciator operation is automatic. When an
alert condition initially happens, the corresponding warning
annunciator lamp (opt.) will begin to flash and a pulsing audio side
tone output is generated. This flashing and audio will continue for a
short time period, after which the flashing will change to a steady 'on'
condition and the audio will extinguish.
If you have connected an optional 'Acknowledge Switch’, the flashing
and audio can be terminated by pressing the switch for a short period
of time. Continuing to hold the switch down will generate a ‘SELF
TEST’ function that tests the annunciator lights and audio output.
The following is a list of annunciated alerts:
OIL TEMPERATURE - oil temp has been exceeded
OIL PRESSURE - oil pressure is too low
FUEL PRESSURE - fuel pressure is too low
FUEL COMPUTER TOTAL - computer fuel total is too low
LEFT TANK - left tank fuel level is too low
RIGHT TANK - right tank fuel level is too low
CENTER TANK - center tank fuel level is too low
