Signet 2580 FlowtraMag Meter
Troubleshooting
Symptom
Possible Cause
Solution
Measurement
inaccurate
1. Improper calibration.
2. Sensor fault as indicated by the
Red LED.
3. Media conductivity is lower than
20 μS/cm.
1. Use the GF Confi g Tool App or 0252
Confi guration Tool to reset fl ow and/or zero
calibration. If user intends to calibrate using
installed reference, proceed with zero and/or one
point fl ow calibration.
2. Cycle power, make sure there is no excessive
electrical noise interference. If Red LED stays
on, contact Technical Support.
3. Check application and make sure the
conductivity is above the specifi ed 20 μS/cm.
User cannot
communicate
using the 0252
Tool
1. There is no digital (S
3
L)
communication.
2. The digital (S
3
L) wiring is improper.
1. Select S
3
L from GF Confi g Tool or 0252
Confi guration Tool.
2. Check wiring as per manual.
User cannot
communicate
using the
Bluetooth
®
1. The GF Confi g Tool App is not
installed properly.
2. The GF Confi g Tool App has not
been identifi ed properly.
3. The GF Confi g Tool App does
not connect.
1. Check the Bluetooth
®
white light to be on.
2. Use the GF Confi g Tool App to identify the
FlowtraMag to connect to (use elimination
method if more Bluetooth
®
units present.)
Record the FlowtraMag's IDs, or delete
unused sensors.
3. Restart GF Confi g Tool App.
4 to 20 mA
output is
incorrect
1. The 4 to 20 mA in the FlowtraMag
is not scaled properly.
2. The Instrument used with the
FlowtraMag has the 4 to 20 mA
input not matching the FlowtraMag.
3. The setting and/or wiring for active /
passive 4 to 20 mA is
done incorrectly.
4. Defective hardware.
1. Scale the current output in the FlowtraMag
correctly using the GF Confi g Tool App or the
0252 Confi guration Tool.
2. Change the Instrument scaling to match
the FlowtraMag.
3. For active AO, select ACTIVE from the
GF Confi g Tool or 0252 Confi guration Tool.
In this case, current output connects directly to
AO 4 to 20 mA connector with correct polarity,
see wiring in the manual.
For passive AO, select PASSIVE from the
GF confi g Tool or 0252 Confi guration Tool.
Wiring is done from AO 4 to 20 mA connector
using the loop power, as indicated in the manual
wiring diagram.
4. If the Green LED bar, % output indicates
correctly the % fl ow and the current output is not
working properly, fi rst check AO selection in GF
Confi g Tool or 0252 Confi guration Tool. If AO
selection is correct, call Technical Support.
Current Output
at 3.6 mA or
22 mA
There is an error condition in
the FBM.
Check status LED and follow existing guideline for
troubleshooting.
