700 Sensor HRT Bridge IM Rev.0.2 Page 8 of 18
• Sensor fault – The sensor cell has failed
• Zero Fault – the sensor drifts below –10% of full range
• Sensor Fault 2 – heater fault (TP-700), bridge fault (FP-700), or missing cell (DM-700). This status is
not used by the IR-700 or PI-700.
• Sensor in Calibration – The sensor is currently being calibrated
4.2.3 HART Status
The HART status section of the screen shows the status of the HART interface on the HRT Bridge PCA.
Icons next to each error description indicate if an error has occurred. A green icon indicates the error condition
is not present and a red icon indicates an error has occurred.
• Unique ID Not Set – The unique device ID for the HRT Bridge PCA has not been set. This ID is set at
the Detcon factory prior to shipping. If this error occurs, please contact Detcon technical support.
• DAC Zero Not Calibrated – The 4mA output of the HRT Bridge PCA has not been calibrated. Please
see Section 4.3.2.2 for calibration instructions
• DAC Span Not Calibrated – The 20mA output of the HRT Bridge PCA has not been calibrated. Please
see Section 4.3.2.2 for calibration instructions
• Modbus Communications Lost – The Model 700 sensor has failed to respond to more than 3 Modbus
poll requests. This error condition can be reset using the “Reset Comm Lost Status” button that
appears when this error condition occurs
4.3 Device Setup Menu
The Device Status Menu consists of three sub menus that allow parameters within the HRT Bridge PCA, and
within the sensor to be changed or modified, and allows calibration of the sensor.
4.3.1 Configuration Setup
The Configuration Screen displays the configuration of the Model 700 sensor. There are no fields that can be
changed on this screen, these fields are read directly from the Model 700 sensor.
