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 Quick Start 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.
• Ensure the wiring is rmly connected to any PreAmp being used.
Noisy Input Alarm • Verify there is a jumper on correct terminals:
• 15 - 18 for Ultra Mag, FPI Mag 395L, and SPI Mag
• 18 - 19 for FPI Mag 394L
• Verify the converter ground is to earth ground
• Check for damaged cable between the sensor and converter
Empty Pipe Alarm • Increase threshold to 250.
• Conrm the pipe is full. If pipe is always full, turn o EP Detect
• Verify there is a jumper on correct terminals:
• 15 - 18 for Ultra Mag, FPI Mag 395L, and SPI Mag
• 18 - 19 for FPI Mag 394L
• Check that sensor is properly grounded
• Conduct a bucket test to conrm 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 men
• Check grounding connections
• Check power circuit. What other devices are on the circruit
• Install dedicated ground circuit
Menu Not Accessible • Conrm the password being used is 000002
• Verify dip switches in the back panel next to the terminals 1 and 2
are both down.
Rate Of Flow Report Is Not As
Expected
• Conrm the unit is programmed correctly by requesting a program
setting report from the factory.
