1 Troubleshooting
This appendix describes problems that may occur during use of the SJ-M Series and how to remedy
them. 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 high temperature use set?
When the power is turned ON for the first
time, or a different model of Static Elimination
Head is installed, perform the “High
temperature use setting.”
"High temperature use setting" (page 8)
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 Electrode Unit for any conductive
substances (e.g. oil droplets).
Static elimination is
not performed
properly. Are conductors or other static
eliminators located near this 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 Electrode Unit.
Are conductive objects located in
the surrounding area? Check the installation location.
"Installation site" (page 5)
The condition alarm is
output/indicated.
Are static elimination target objects
having a very high charged level
located near 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 Electrode Unit.
The alarm indicator
lights.
–
Check “During an alarm (levels 1, 2)”
(
page 15) 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.
–
Check "Table of Indicated States" ( page
14) in this Instruction Manual.
2 Table of Indicated States
This appendix describes the various indicated states of the SJ-M Series.
■ Indicated state when the power is turned ON
■ Indicated states when the power is turned ON for the first time or when a
different model Static Elimination Head is connected
Lit State Description
The state (charged level indication or ion
level indication) that was active before the
power was turned OFF is displayed.
At the same time, the alarm indicator, ion
level alarm indicator, and condition alarm
indicator light (red).
The ion monitor LEDs fluctuate upward
and downward.
When the power is turned ON, the indicated state (charged level
indication or ion level indication) that was active before the
power was turned OFF is displayed. Also, the alarm indicator,
ion level alarm indicator and condition alarm indicator light (red)
at the same time. After this indication state continues for about
two seconds, the ion monitor LEDs fluctuate upward and
downward, and static elimination is then started. After static
elimination starts, the charged level or ion level is indicated.
Lit State Description
When the power is turned ON for the first time after purchase,
the SJ-M Series starts up at the “High temperature use setting”
in the Setup mode. At this time, static elimination is not
performed.
For details on setting items and how to set up setting items, see
the following:
"High temperature use setting" (page 8)
Make the settings match the actual operat-
ing environment. Incorrect settings may
cause accidents or malfunction.
Blink alternately at high speed
