ALARM
MESSAGES
POSSIBLE CAUSES AND SOLUTIONS
Excitation failure • Incorrect connections of cables
• Sensor damaged. Damaged lining or electrodes. Possible infiltration of
liquid inside the sensor
• Converter damaged
It is recommended to perform a test on the sensor -> circuit between coils
A - B: 50 - 250 Ohm
Request the “sensor test” to the factory
Measurement error • Empty Pipe
• Air bubbles within the liquid
• Incorrect electrical grounding
It is advisable to check for correct installation of the sensor in the three points
indicated and carry out a test on the sensor -> with full pipe (A or B) - ground
> 100 MOhm
Empty Pipe • Empty pipe detection
This message is displayed with sensors that have 4 electrodes. Indicates
the alarm of empty pipe, or even only partially empty. In case of persistent
message with full pipe (more than a few minutes) act on the empty pipe
threshold (see section 10.3.6 Empty pipe threshold).
Pulses accumulation • Pulse frequency incorrect
It is advisable to change the volume settings and pulse duration. See the
section for pulse output setting
Supply voltage • Supply voltage out of operating range
• Converter damaged
Check the power supply network
Data logger full • Data logger memory full
It is advisable to download the data to PC, and erase the memory of the
converter
