Operation
Turning Off Static Elimination
Static elimination can be turned off using the Controller Unit or the Static Elimination Blower Unit in a
powered ON state.
This section describes each adjustment procedure to turn off static elimination.
■ Operation using the Controller Unit
Shorting the static elimination stop
input terminal [4] and the 0 V terminal
[5] turns off static elimination.
When static elimination turned off,
the power indicator on the Controller Unit blinks in green.
■ Operation using the Static Elimination Blower Unit
Pressing and holding
for about two seconds turns off static elimination.
When static elimination turned off, the center LED of the monitor lights in red.
If static elimination is turned off before turning off the power in the initial use of this product,
turning on the power next time will not start static elimination automatically.
Refer to
"Starting Static Elimination" (page 6) for details about how to start static
elimination.

The LED lights up towards the + side or
the - side to indicate the charged level
of the target object.
The LED lit closer to the end (red)
indicates higher charged level.
When static elimination is completed,
the center LED of the monitor lights in

indicator to display the ion level
monitor.
The amount of plus ions being emitted
is indicated on the + side; and the
amount of minus ions is indicated on
the - side.
The LED lit closer to the end (green)
indicates higher ion level. When ions
are emitted to the full, the LEDs on the
both ends light in green.

About Display Function
■ Ion level alarm output function
This function causes the ion level alarm indicator to blink and an alarm signal (control output [N.O.]) to
output when the ion emission level has dropped below the setting value due to dirt or wear of the
electrode needles in the connection units.
Refer to
"Adjusting Ion Level Alarm Sensitivity" (page 7) for details about ion level alarm
sensitivity setup.
This alarm output will not stop static elimination. Be sure to turn the power OFF
before starting maintenance on the electrode needles.
• Once this alarm has been output, the alarm is kept output until the power is turned
off, static elimination is turned off, or the ion level alarm sensitivity is reset.
• In the case where the Static Elimination Blower Units are used in connection, the
alarm signal is output when ion level alarm condition occurs even in one of these
units.
