Sensor alarms
These settings are used to set up the PI44 parameters related to
sensor alarms.
To access the parameters, press the MENU button to open the
main menu. Then, open the Setup menu, and select Sensor
alarm/calibration .
Each sensor has an individual alarm setting, and you can also
trigger alarms to warn you about sudden temperature changes
and shallow water. Whenever an alarm is triggered an audible
signal is provided, and a message on the display presents the
cause of the alarm. Unless the reason for the alarm is corrected,
or the alarm disabled, it will sound again after 20 seconds.
Due to the amount of choices available for the PI44, the alarm
parameters are organized in three dialogues.
•
Sensor alarm: This dialogue allows you to defined alarms
related to the information provided by the sensors.
•
Surface temperature: This dialogue allows you to set up
alarms to warn you about surface temperatures, and to
indicate sudden temperature changes.
•
Clearance: This dialogue allows you to define alarms to
monitor if a trawl or towed object comes too close or too far
off the bottom.
The Sensor alarm/calibration choice on the Setup menu also
allows you to define parameters for depth calibration and offset.
These are explained separately.
