Information on the Measuring Point
Diagnosis and Troubleshooting
Prosonic T distinguishes between the operating faults alarm and warning.
2-wire
If the Prosonic T Identifies an Alarm
• if the display is plugged in, the
bargraph flashes
• the current output adopts a
preselected value (–10% = 3.8 mA,
+110%, HOLD)
• an error code is output in V9H0
4-wire
If the Prosonic T Identifies an Alarm
• the red LED lights up
• if the display is plugged in, the
bargraph flashes
• the current output adopts a
preselected value (–10% = 2.4 mA,
+110%, HOLD)
• an error code is output in V9H0
If the Prosonic T Identifies a Warning
• the instrument continues to measure
• an error code is output in V9H0
If the Prosonic T Identifies a Warning
• the red LED flashes
• the instrument continues to measure
• an error code is output in V9H0
Code Type Cause and Removal
E 101 Alarm Check sum error EEPROM/FRAM - Contact Endress+Hauser Service.
E 102 Warning Check sum error EEPROM/FRAM - Contact Endress+Hauser Service.
E 103 Warning Initialization starting. If error remains, initialization cannot be started.
E 106 Alarm Download in progress – Wait until completed.
E 110- Alarm Reset instrument, if error remains, electronic instrument error.
E 121 Contact Endress+Hauser Service.
E116 Alarm Error with download – Carry out reset or restart download with corrected
data.
E125 Alarm Defective sensor – Check sensor connection. Contact Endress+Hauser
Service if error remains.
E261 Alarm Error in temperature sensor – Contact Endress+Hauser Service.
E 501 Alarm Sensor electronics not recognized – Contact Endress+Hauser Service.
E 602 Warning Linearization curve is rising continuously – Check manual linearization
curve. Does the volume increase with height?
E 604 Warning Linearization curve has less than 2 points – Check manual linearization
curve and enter more points.
E 605 Alarm Linearization table not available – Appears while entering the
linearization curve. Activate the linearization curve after entering all
points.
E 613 Warning Simulation activated – Switch to normal operation after simulation is
completed. Simulation off: V9H6: 0
E 620 Warning Current outside range – Check calibration and settings of the current
output.
E 641 Alarm No usable echo
– Due to loss of echo (e.g. foam) or when measuring starts
– Check calibration and operating range
Contact Endress+Hauser Service if error remains.
E 661 Warning High Temperature (greater than 176°F/80°C) – Check measuring
conditions.
