Parameters
4.2.9. Acknowledge
Acknowledges the current maintenance reminder.
To acknowledge an alert via the handheld programmer:
a) Press RIGHT arrow twice to open parameter view and activate Edit
Mode.
b) Press RIGHT arrow to acknowledge the alert.
4.3. Remaining Sensor Lifetime
The device monitors the predicted lifetime of the sensor (the components exposed to
the vessel environment). You can modify the expected sensor lifetime, set up schedules
for maintenance alerts, and acknowledge them.
To access these parameters via AMS Device Manager see Remaining Sensor
Lifetime on page 56 under Maintenance & Diagnostics (LTB) .
4.3.1. Lifetime Expected
Allows you to override the factory default.
4.3.2. Time in Operation
The amount of time the sensor has been operating. Can be reset to zero after
performing a service or replacing the sensor.
To reset to zero:
• Via the handheld programmer, manually reset Time in Operation (4.3.2.) to
zero.
Notes:
• Default settings in the parameter tables are indicated with an asterisk (*) unless
explicitly stated.
• Four sets of parameters allow you to monitor the Device/Sensor Lifetimes and
set up Maintenance/Service schedules, based on operating hours instead of a
calendar-based schedule. See also Remaining Device Lifetime (4.2.), Service
Schedule (4.4.), and Calibration Schedule (4.5.).
• Performing a reset to Factory Defaults will reset all the Maintenance Schedule
parameters to their factory defaults.
• The device operates in years. To view Remaining Sensor Lifetime parameters in
hours (via AMS Device Manager only) see
Remaining Sensor Lifetime on page
56.
