Overview

Latched alert action is recommended if 3rd party alert monitor software is
likely to miss alerts due to slow polling of HART data.
High Alert Value / Low Alert Value
These are independent trip values for the diagnostic. These values are
represented on the graph by the red lines.
Total Event Time (High / Low)
These fields show the total time the transmitter's module temperature was
above the High Alert Value or below the Low Alert Value.
Time Since 1st Event (High / Low)
This is the elapsed time since the first Temperature Alert event for High Alert
Value and Low Alert Value. Subsequent events will increment the Total Event
Time values but this value will remain unchanged.
Number of Events (High / Low)
This is the number of times the transmitter's module temperature was above
the High Alert Value or below the Low Alert Value.
Reset Alert Events
Selecting this will reset all time stamp values and number of events to zero.

Service Alert can be used to generate a time-based HART alert with
customizable message. This can be used to remind personnel when to
perform maintenance on the transmitter. When the alert is generated, the LCD
will indicate "TIMER ALERT" and a HART alert will be generated by the
transmitter. An active alert will not affect the transmitter's 4 – 20 mA output
signal.
