Error Possible Reason Correction
Check for correct connection.
Check for crushed or damaged sensor
cables/extension cables, short circuits, surge
arresters, or improper resistance loads.
Check the level signal, echo profile, flow
velocity signal, cable parameters, and
temperature from I/O menu.
Sensor
Verify that the sensor is installed in a
vibration-free location. Check sensor
installation for orientation to flow, horizontal
position, and presence of silt.
Configuration Verify proper settings for measurement
location, such as pipe shape and dimensions
(and units), sensor type, and sensor
installation height.
Check connections on terminal clamp strip.
Check power supply for external control
relays.
Check signal output in the I/O menu.
Connection
Check output control function in calibration
menu.
Transmitter Verify transmitter type. While Model 10
transmitters have only 2 relay outputs, Model
20 transmitters have 5 relays.
Verify that relay outputs have been enabled.
Verify outputs are properly assigned to their
respective output channels.
Faulty Relay Output
Configuration
Check additional values, such as impulse
parameters, limit values, and logic.
Check terminal clamps. Relays 4 and 5 are
dedicated to controller function.
Check the power supply for the external
control relays.
Check the input signals from the limit
contacts and setpoint.
Connection
Check the output control function manually
through menu-driven controller operation.
