■ Indications in the Run mode
Lit State Description
One of the ion monitor LEDs and the ion
balance indicator light (red).
Charged level indication
This indicates the charged level of the target object. When there
is a plus charged object, the LEDs on the upper side (+ side)
light, and when there is a minus charged object, the LEDs on
the lower side (– side) light according to the charged level.
One each of the plus and minus side
LEDs of the ion monitor, and the ion level
indicator light (red).
Ion level indication
This indicates the level of ions that are being generated by the
SJ-M Series.
Charged level indication or ion level
indication
Display selection
The display switches to the charged level indication when
(DISP) is pressed while the ion level is indicated.
When the charged level is indicated, the display switches to the
ion level indication.
The ion balance indicator lights, and one
of the ion monitor LEDs blinks.
Ion balance manual setup confirmation
If the device is not in an ion balance manual setup state, you
can confirm the ion balance manual setup by pressing either of
the ion balance adjustment keys. During confirmation, the ion
monitor LEDs blink in one of the following three colors:
Orange: The LED blinks (orange) at the position corresponding
to the setup state when ion balance manual setup is
being performed. (Sometimes the center LED also is
lit.)
Red: The LED at the edge of the side (+ or –) that was set
blinks (red) when the set value was set to MAX during
ion balance manual setup.
Green: The center LED blinks (green) for the duration that the
ion balance adjustment key is held down when ion
balance manual setup is not being performed.
Hold down for
less than 1 second.
Table of Indicated States
The condition alarm indicator lights (red).
Condition alarm
The condition alarm indicator lights (red) when the ion balance
has deteriorated due to influence from the installation
environment.
The ion level alarm indicator lights (red).
Ion level alarm
The ion level alarm indicator lights (red) when the generated ion
level falls below the preset level.

■ Other indications
Lit State Description
The center LED of the ion monitor blinks
(red).
Static elimination stop input (I/O terminal section)
The center LED of the ion monitor blinks (red) when the static
elimination stop input and 0V terminals are shorted to stop static
elimination.
The three center LEDs of the ion monitor
blink (red).
Static elimination stop input (operation/display section)
The three center LEDs of the ion monitor blink (red) when
are pressed and held down at the same time for about
three seconds to stop static elimination.
The alarm indicator and the three center
LEDs of the ion monitor blink (red)
simultaneously.
During an alarm (level 1)
The alarm indicator and the three center LEDs of the ion monitor
blink (red) simultaneously in the following instances.
Remedy the cause of the alarm, and simultaneously hold down
for about three seconds. This cancels the alarm state,
and executes the power ON sequence.
Probable causes of alarms
• Cables are disconnected or broken.
The alarm indicator and the seven ion
monitor LEDs of the ion monitor blink (red)
simultaneously.
During an alarm (level 2)
The alarm indicator and seven LEDs of the ion monitor blink
(red) simultaneously in the following instances.
Remedy the cause of the alarm, and turn the power ON again.
If this alarm frequently re-occurs, contact KEYENCE.
Probable causes of alarms
• Abnormal discharge
•
Internal circuit damage
Seven ion monitor LEDs of the ion monitor
blink (red) simultaneously.
Ion balance adjustment incomplete
The has been pressed when the ion balance adjustment is
not yet complete.
Table of Indicated States
The BLANCE, ALARM, ION LEVEL COND
display lamps and the upper and lower
ends of the ion monitor are
simultaneously blinking red.
Ion balance adjustment malfunction
The DIP switch for ion balance adjustment is centered.
