TROUBLESHOOTING & ERROR MESSAGES

Problem

Probable Causes

Things to try…

Blank Display

Faulty wiring from power source to

meter

Check for incorrect wiring. Measure voltage with

DMM where red and black wires connect to terminal

block TB1 on back side of display. Verify correct

polarity and confirm that voltage is steady and

between 9Vdc and 32Vdc

Battery has not been plugged in

Plug in the battery

Dead battery

Replace battery

Flow rate reading fluctuates

excessively when flow is

unchanging

Excessively turbulent or unsteady flow

due to partially closed valves or other

flow obstructions

Eliminate or minimize causes of flow disturbances or

increase meter damping

Pipe not full

Provide back pressure or other means to ensure pipe

is filled

Pulsing flow due to combining multiple

upstream flow sources

Move connection point further upstream

Insufficient mixing of upstream

chemicals

Move chemical injection downstream from meter

Low fluid conductivity < 20 µS/cm

Replace with different type of meter

Noisy electrical environment

Improve grounding at meter and nearby potentially

noisy electrical equipment. Increase distance between

meter and electrical noise sources.

Defective or noisy AC switching power

supply

Replace power supply

Flow Rate appears correct but

pulse/ frequency output is low,

erratic or absent

Wiring incorrect

Compare wiring with appropriate wiring

recommendations

External device input impedance too

low

Use sourcing rather than sinking interface connection

Cable too long

Reduce interface pull-up resistance

Flow Rate appears correct but

pulse/frequency output is erratic

and/or too high

Electrical noise sources interfering with

pulse frequency signal

Isolate, remove or reduce noise sources. Move meter

control cable away from noise sources.

Wrong type of cable

Use only twisted pair cable and ensure both signal

wires are on same twisted pair

Grounding problem

Improve or try different grounding method

Message

Description

Notes

INIT

Initialization is occurring during power up.

EMPTY PIPE

Fluid is not detected between the sensing electrodes.

Loop output = 22.8mA

LO in battery icon

Battery is getting low, replace soon. Meter still functions.

Above 6.4V, OK appears in icon

BATT END

Battery is very low (approx. 6.1V). Totalizer stops updating.

Loop output = 4mA

LOW VOLT

Incoming external power is very low and backup battery is dead

or not connected

Loop output = 4mA

COIL FAIL

Coil current too high or too low (short or open).

Loop output = 22.8mA

COMM FAIL

Communication between transmitter and sensor board fails.

Loop output = 22.8mA

OVER RANGE

Rate exceeds number of digits that can be displayed. Adjust units. Loop output = 4mA

Troubleshooting

Error Messages

Under certain conditions an error message may be displayed.
