Informationon The Measuring Point; Diagnosis And Trouble-Shooting - Pepperl+Fuchs LUC-T10 Bedienungsanleitung

15 Informationon the measuring
point
15.1 Diagnosis and trouble-
shooting
LUC-T distinguishes between the
operating faults alarm and warning.
2-wire
If the LUC-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
If the LUC-T identifies a warning
• the instrument continues to measure
• an error code is output in V9H0
4-wire
If the LUC-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 LUC-T identifies a warning
• the red LED flashes
• the instrument continues to measure
• an error code is output in V9H0

Code Type
E 101 Alarm Check sum error EEPROM/FRAM - Contact Pepperl+Fuchs service line.
E 102 Warning Check sum error EEPROM/FRAM - Contact Pepperl+Fuchs service line.
E 103 Warning Initialising starting.
If error remains, initialisation cannot be started.
E 106 Alarm Download in progress – Wait until completed.
E 110 Alarm Reset instrument, if error remains longer electronic instrument error – Contact
... Pepperl+Fuchs service line.
E 121
E 116 Alarm Error with download – Carry out reset or restart download with corrected data.
E 125 Alarm Defective sensor – Check sensor connection, contact Pepperl+Fuchs service line if
error remains.
E 261 Alarm Error in temperature sensor – Contact Pepperl+Fuchs service line.
E 501 Alarm Sensor electronics not recognised – Contact Pepperl+Fuchs service line.
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 Linearisation table not available – Appears while entering the linearization curve. Active
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 voltage.
Contact Pepperl+Fuchs service line if error remains.
E 661 Warning High Temperature (greater than 80 °C/176 °F) – Check measuring conditions.
