Code Type Cause and Remedy
E 101-106 Alarm Fault in instrument electronics
- Call Endress+Hauser Service
E 107 Alarm Battery voltage too low
- Make back-up of entered parameters immediately
- Have battery changed at once by trained personel or ring for service
E 201-202 Alarm Fault in probe on channel 1 (f < 35 Hz; f > 3000 Hz)
- Check probe and electronic insert
E 301-302 Alarm Fault in probe on channel 2 (f < 35 Hz; f > 3000 Hz)
- Check probe and electronic insert
E 400 Alarm Fault in probe on channels 1 + 2
- Check probe, electronic insert and wiring
E 401 Alarm Fault in probe or wiring, channel 1
- Check probe, electronic insert and wiring
- Incorrect operating mode
E 402 Alarm Fault in probe or wiring, channel 2
- Check probe, electronic insert and wiring
- Incorrect operating mode
E 600 Warning PFM transmission internal code check
- can be ignored if it appears only briefly
E 601 Warning PFM transmission internal code check
- can be ignored if it appears only briefly
E 602 Warning Linearisation does not rise monotonously (volume does not increase
with level)
- Check and re-enter correct values, reactivate linearization
E 604 Warning Linearisation has less than two sets of values
- Enter more values, reactivate linearization
E 606 Warning No stored factory linearization (V2H6 = 0)
- Select another linearisation function at V2H0
E 608 Warning Value in V0H5 greater than that in V0H6
- Check input
E 610 Warning Calibration fault, channel 1 (»empty« level > »full« level)
- Repeat calibration
E 613 Warning Instrument in simulation mode, channel 1
- Switch back when finished
E 614 Warning Instrument in simulation mode, channel 2
- Switch back when finished
