External level
signals Check for correct connection.
Check if cables are crushed.
Check for short circuits and improper resistive
loads or current consumers without galvanic isola-
tion.
Check measurement range and span.
Check input signal in I/O menu.
Sensor Check for correct connection.
Check if cables are crushed.
Check for extensions/cable types, short circuits,
surge arresters or improper resistive loads.
Check level signal, echo profile, flow velocity sig-
nal, cable parameters and temperature in I/O
menu.
Check if sensor is installed on a vibration-free
place. Check sensor installation (towards flow
direction, horizontal installation), check sensor for
soiling.
Programming Check if the correct shape of measurement place
has been set, check dimensions (observe units),
sensor type, sensor installation height etc.
Faulty relay output Connection Check connections on terminal clamp strip.
Check power supply of external control relays.
In I/O menu check signals to be output.
Check output control function in calibration menu.
Programming Check if relay outputs are enabled.
Check if outputs are correctly assigned to respec-
tive output channels.
Check additional values such as impulse parame-
ters, limit values, logic etc.
