3.3 Alarm Indicators
Yellow Warning Light
– A flashing yellow light indicates that there are unacknowledged active warnings. A solid yellow
light indicates that there are acknowledged warnings active. If there are any active warnings, the yellow light will
change from flashing yellow to solid yellow after the Alarm Acknowledge key is pressed. If there are no longer any
active warnings, the yellow light will turn off after the Alarm Acknowledge key is pressed.
Red Shutdown Light
– A flashing red light indicates that there are unacknowledged active shutdown events. A solid
red light indicates that there are acknowledged shutdown events active. If there are any active shutdown events the
red light will change from flashing red to solid red after the Alarm Acknowledge key is pressed. Any condition that has
caused a shutdown event must be manually reset. If there are no longer any active shutdown events, the red light will
turn off.
Alarm Acknowledge
– Pressing the Alarm Acknowledge will cause the horn relay output to turn off and silence the
horn (if installed). Pressing the key will also cause any yellow or red flashing lights to turn off or to become solid
depending on the active status of the alarms. The Alarm Acknowledge may also be configured to send out a global
alarm silence on the J1939 Data Link, which will silence horns on annunciators. Pressing and holding the Alarm
Acknowledge key can be used to reset all active warnings or shutdowns.
