TROUBLESHOOTING GUIDE
Trouble
Remedy
No LCD
Display
Battery
Check battery voltage Should be 3 6 V DC If the input is 3 4V DC or lower, replace the battery
Loop
power
Check 4…20 mA input Voltage must be within the minimum and maximum supply voltage and
capable of supplying enough current to run the display The input voltage is checked “across” or
in parallel with the 4…20 mA terminals and current is checked with the ammeter in series with
the 4…20 mA output
No Rate or Total
Displayed
Check connection from meter's transmitter to display input terminals
Check turbine meter rotor for debris Rotor should spin freely
Check programming of flow monitor
Flow Rate Display
Interprets Reading
Constantly
This is usually an indication of external noise Keep all AC wires separate from DC wires
Check for large motors close to the meter pickup
Check for radio antenna in close proximity
Flow Rate Indication
Erratic
This usually indicates a weak signal Replace pickup and/or check all connections
Check for correct factor
Check that the ILR transmitters meter size selection switch is set to the correct size
