Total Event Time (High / Low)
These fields show the total time the transmitter’s input pressure 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 Pressure 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 input pressure 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.
Temperature Alerts
Figure 7-24. Module
Temperature Alert screen
Figure 7-24 shows the configuration section for Temperature Alert. If ambient
temperature goes above or below the alert values, the LCD will indicate a
temperature 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.
Alert Mode
This setting dictates whether the diagnostic is On or Off. Selecting “On
Unlatched” will generate a HART alert when the alert values are tripped.
When temperature returns to normal and within the alert limits, the alert is
automatically cleared. Selecting “On Latched” will generate the same HART
alert but will require a manual reset to clear the alert.
