Troubleshooting
This appendix describes trouble that may occur during use of the SJ-M Series and how to remedy this
trouble. Check the following table before sending in your SJ-M Series for repair.
Symptom
Check Item
Remedy
No indication on ion
monitor
Is the power cable connected
properly?
Connect the power cable correctly.
Is a power supply within specification
being used?
Use a power supply that is within
specification.
Static elimination is
not performed.
Is the electrode probe worn or dirty?
Perform maintenance on the electrode probe
or replace the Electrode Unit.
Is static elimination stop currently
set?
Cancel static elimination stop input on the SJ-
M Series.
Is the abnormal discharge detection
function operating?
Check the Static Elimination Bar for any
conductive substances (e.g. oil droplets).
Static elimination is
not performed
properly.
Are conductors or other Static
Eliminators located nearby the Static
Eliminator?
Move the Static Eliminator away from
conductors or other static eliminators nearby.
The ion level alarm is
output/indicated.
Is the electrode probe worn or dirty?
Perform maintenance on the electrode
probes or replace the Static Elimination Bar.
Are conductive objects located in the
surrounding area?
Check the installation state.
"Locations"(page 5)
The condition alarm is
output/indicated.
Are static elimination target objects
having a very high charged level
located nearby the Static
Eliminators?
Increase the number of connected static
eliminators.
Is the electrode probe worn or dirty?
Perform maintenance on the electrode
probes or replace the Static Elimination Bar.
The alarm indicator
lights.
–
Check “During an alarm (levels 1, 2)”
(
page13) in this Instruction Manual.
Control output is not
output correctly.
Is output wired correctly?
Check the output circuit and wiring, and
connect correctly.
Static elimination stop
input is not input
correctly.
Is input wired correctly?
Check the input circuit and wiring, and
connect correctly.
Do not know meaning
of indicators.
