Rosemount 3051S Series

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 ALERTS

Overview 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.
