12.0 TROUBLESHOOTING GUIDE
Problem Troubleshooting Steps
Not getting expected 4-20mA output • Ensure the wiring is rmly connected on the 4-20mA output terminals
• Verify resistor removed from terminal block
• Verify the FS1 setting in the main menu is set to the correct value, matches
PLC/SCADA value
• Measure output on the 4-20mA terminals and compare it to the calculated
current value
Curr. Loop Open Alarm • Ensure the wiring is rmly connected on the 4-20mA output terminals
• If the 4-20mA output is not being used, ensure the 4-20mA terminals have a
load resistor installed
• Remove the wires from the 4-20mA terminals and measure the current
output direct
Excitation Fail (0800) Alarm • Ensure the wiring is rmly connected
• Disconnect the coil wires from the converter and check their resistance with
a standard multi-meter. Contact the factory for the proper value for the
sensor.
Noisy Input Alarm • Verify the converter ground is to earth ground
• Check for damaged cable between the sensor and converter
Empty Pipe Alarm • Increase threshold to 250 kΩ.
• Conrm the pipe is full. If pipe is always full, turn o EP Detect
• Check that sensor is properly grounded
• Conduct a bucket test to conrm the EP Threshold value is set correctly.
Consult the factory for assistance.
• Check for damaged cable between the sensor and converter
Unstable Flow Readings • Check installation straight run requirements are met
• Check grounding connections
• Check power circuit. What other devices are on the circruit
• Install dedicated ground circuit
Menu Not Accessible • Conrm the password being used is 400000
Rate Of Flow Report Is Not As
Expected
• Conrm the unit is programmed correctly by requesting a program setting
report from the factory.
!
WARNING!
Ensure device is disconnected or circuit breaker is open per the requirements of IEC 60947-1 and IEC 60947-3
before opening the opening the converter.
