2.3.1 Troubleshooting
Problem Solution
Transmitter does not track level (External Mount) Remove transmitter from piping column and test with
re-alignment magnet. Run magnet from bottom to top of
probe. Check zero and span calibration. If no change in
output, consult the factory.
(Direct Insertion) Float stuck, Probe bent (Chamber)
Float inside the level gauge is moving slow Ensure that the magnetic level indicator is plumb.
or not at all.
The process fluid being measured may be too viscous and
heat tracing may be required to make the material more fluid.
The specific gravity of the process fluid and float weight may
need to be reverified.
The liquid being measured may contain magnetic particles
collecting on the magnetic section of the float causing drag.
If this happens magnetic trap assemblies can be purchased
from the factory.
Visual inspection of the float may be required to see if the float
has collapsed.

loop values.
LEVEL, % OUTPUT, and LOOP values fluctuate. Turbulence, increase damping factor until readings stabilize.
Level reading on display is correct, but loop Set poll address to zero
value is stuck at 4 mA.
2.3 Troubleshooting
The Jupiter transmitter is designed and manufactured for years of trouble free operation over a wide
range of conditions. Common transmitter problems are discussed in terms of their symptoms and
recommended corrective actions.
Caution: Do not rotate the Jupiter electronics enclosure or any threaded fittings.
Rotating the electronics enclosure will void warranty and could cause
damage to sensor cables.
