Table7.2 Field Diagnostic Alert
Indication of FD_*_ACTIVE Indication of FD_RECOMMEN_ACT Solution
Electronics failure Repair electronics Replace electrical parts e.g. amplifier.
Or contact sales office or service center.
Sensor/Actuator failure Repair Sensor/Actuator Replace mechanics e.g. sensor or
actuator. Or contact sales office or service
center.
Potential failure Investigate failure Perform reconfiguration, cleaning, wiring/
connector or electrical board check.
If alarm still persists, contact sales office or
service center.
Backup function in operation Repair primary side Repair primary sensor before backup
sensor fails.
Firmware update error Retry updating firmware Retry firmware update. Check cause of the
failure if alarm persists.
Communication configuration error Configure communication correctly Correct configuration of communication.
Non-operating-state Wait for a while Wait for a while. Check cause of the failure
if alarm persists.
Calibration warning Check calibration Investigate cause of failure and recalibrate
device.
Device configuration error Configure device correctly Correct configuration relating to sensor or
actuator.
Function restricted Confirm the state Check if this is right state.
Simulation mode Confirm the state Check if this is right state.
Manual mode Confirm the state Check if this is right state.
Function Block notice Check Function Block status Check conditions of function blocks. In
order to avoid alarm from unused function
blocks, configure RESOURCE2.FD_
EXTENDC_MAP_n (n: 1 to 3) parameter.
Sensor/Actuator out of range Check specification Check specification of sensor and
actuator. Or process conditions may be
temporarily non-conforming.
Out of operating limit Check environment Check environment specification of sensor
and actuator. Or process environment may
be temporarily non-conforming.
Temporal decrease of value quality Check process or peripherals Check process and peripherals conditions.
Deterioration estimated by Time
Based Maintenance
Check deterioration Check if maintenance is required.
Deterioration estimated by
Condition Based Maintenance
Check deterioration Check if maintenance is required.
Impulse Line Blockage Detected Check process and impulse line
condition
1.Check process and impulse line
condition.
2.If there are large flow change or the
change of fluid under the measured
process conditions, obtain the
reference value again.(Please follow
the operation procedure in User
Manual)
Heat Trace Warning Detected Check the heater failure 1.Check the heater failure.
2.Check the capsule temp. and Amplifier
temp.
3.Adjust Flg Temp Coef(STB.FLG_
TEMP_COEF).
Optional function configuration error Check optional configuration Check configuration of optional functions.
Alarm related information Confirm information Check the alarm related information.
Process alarm Check process Check process conditions.
CHECK CHECK Check both modes for the SENSOR and
LCD transducer blocks are AUTO.
