Troubleshooting
Symptom Possible Cause Solution
No LED Lights Unit is not powered or the power wiring
is reversed. Check power wiring, voltage should be
12 to 32 VDC at 24W.
Solid Blue There is no fl ow. If user expects to see
fl ow, the Low Flow Cuto ff value may be
set too high.
Change the Low Flow Cuto ff value in user menu
using GF Con fi guration Bluetooth
®
Tool or
0252 Con fi guration Tool.
Solid Purple Partially fi lled pipe. Flow rate is zero. User should be aware that the pipe could be fi lled
> 50% and water in the pipe is stagnant or the water is
below 50% and water could be stagnant or moving.
Blinking Red Flow measurement is out of range.
If error persists, the LED will become
solid RED after one minute. The spiking of the fl ow outside the normal range could
be caused by excessive EMI or water splattering
through a partially
fi lled pipe and creating fl ow spikes.
The spiking will end once the disturbance is not
present anymore.
Frequency
output does not
work 1. Bluetooth selection is S 3 L.
2. Improper wiring.
1. Select frequency from GF Con fi g Tool or
0252 Con fi guration Tool.
2. Check wiring. Use the wiring diagram picture in
the 2581 FlowtraMag manual.
Frequency,
Digital or
Current Output
is Erratic 1. Electrical Noise interference with the
fl ow measurement.
2. Possible air pockets traveling
through the piping system.
3. Pipe is not full and water
fl ow creates splashing of
the electrodes.
4. Excess turbulence in fl uid
fl ow pro fi le.
1. Verify the grounding of the 2581 FlowtraMag and
of the nearby VFDs and Pumps. If possible, use
grounding rings or connect metal portions of the
piping to closest ground.
2. Check the piping and use vents if possible,
otherwise wait for the air pockets to be eliminated
through the system.
3. Try to keep the pipe full, by installing vertical.
4. Follow product manual recommended xD
installation distances.
Output is not
Zero when
fl ow
is stopped
1. Low Flow Cuto ff fl ow value is lower
than the zero fl ow noise level.
2. Electrical noise is interfering with
the measurement.
3. Defective 2581 FlowtraMag.
1. Adjust the Low Flow Cuto ff value to be above
the noise level.
2. Verify/Modify Grounding.
3. Contact Technical Support.
