700 HART-RAM I.M.

6.2.1 Device Status

Device Status contains one screen that shows the status of the sensor and the HART-RAM. The left side of

the screen (Device Status) displays the status of the HART-RAM, with icons that will display either green to

indicate normal condition, or red to indicate an error, a change, or a malfunction.

Figure 12 Device Status Screen

• Field device has malfunctioned due to a hardware error or failure

• A reset or self test of the field device has occurred, or power has been removed and reapplied

• Field device has more status available

• PV analog channel fixed

• PV analog channel saturated

• Process applied to the non-primary variable is outside the operating limits of the field device

• Process applied to the primary variable is outside the operating limits of the field device

6.2.2 Sensor Status

The Sensor Status section of the screen shows the status of the Model 700 sensor. Icons are used to display

the status of the sensor and display either green to indicate normal condition or red to indicate an error, a

change, or a malfunction.

• Global Fault – The Model 700 sensor has one or more faults.

• Auto span fault – 180 days or more has elapsed since the last successful AutoSpan

• Temperature fault – the detector is currently reporting an ambient temperature that is outside of the –

40C to +75C range

• Loop current fault – The sensor has detected a condition where the 4-20mA output loop is not

functional

• Input voltage fault – The sensor is currently receiving an input voltage that is outside of the 11.5-

28VDC range

• Memory fault – The detector has a failure in saving new data to memory

• Processor fault – The detector has an unrecoverable run-time error
