E3A-JA3A-F11 Datasheet, PDF (39/60 Pages) Magnetrol International, Inc. – Liquid Level Displacer Transmitter

8.3.1 Troubleshooting System Problems
Symptom
No output signal.
LEVEL and % OUTPUT
values are inaccurate.
Transmitter does not
track level.
LEVEL and % OUTPUT
values fluctuate.
Output jumps quickly
over wide range
Non-linear output.
Problem
Solution
Power supply not turned on. Turn on power.
Insufficient source voltage. Minimum of 9 VDC required at the wiring board. Verify supply voltage.
Improperly wired or
damaged wiring.
Check wiring and connections.
Defective electronics.
Replace PC board assembly or wiring board as required.
Basic configuration data is
questionable.
Verify Level Offset values.
If using factory calibration, verify that Process SG and Operating
Temperature values are accurate.
Verify/confirm that Model Parameters are accurate.
Confirm set points are as expected.
Model incompatible with
process liquid
Verify model in use is appropriate for process liquid SG.
Possible damage to unit.
Check displacer, spring, stem and enclosing tube for damage.
Replace all damaged parts.
Possible material buildup
Check displacer, spring, stem, enclosing tube and displacer for
buildup of process material. Clean any fouled parts.
Displacer, spring or stem
dragging on inside of
chamber, e-tube.
Verify proper and level installation (within 3 degrees of plumb in all
directions).
Liquid turbulence.
Increase damping until output stabilizes or install stilling well.
Power supply unstable.
Repair or replace power supply.
Electrical interference (RFI). Consult factory for assistance.
Bent stem impeding smooth Review Status History for Surge event. Inspect stem and replace if
core movement
damaged.
Displacer hanging up.
Verify proper and level installation (within 3 degrees of plumb in all
directions.)
Bent stem.
Check stem. Replace if damaged.
Possible material buildup
Check displacer, spring, stem, enclosing tube and displacer for
buildup of process material. Clean any fouled parts.
