Table 9.2 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.
