3-2 About Display Function

Monitor Display Function

The monitor on the Operation panel allows you to confirm the following states by indication of LED.

■ Displaying charge monitor

Press or to select the ion

balance indicator to display the charge

monitor.

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

green.

■ Displaying ion level monitor

Press or to select the ion level

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.

■ Displaying blow rate setting value monitor

Press or to select the blow

rate indicator to display the blow

rate setting value monitor.

The LED lit closer to the + side

indicates higher blow rate; and the

LED lit closer to the

side indicates

lower blow rate.

About Display Function

Alarm Output Display Function

■ Alarm output function

This function causes the LED indicator to blink i n red and an alarm signal (control output [N.C.]) to be

output when internal circuits are damaged or abnormal discharging occurs.

The alarm output is activated even when static elimination is stopped (including forced stop status).

For details of the LED indicator display, refer to "Table of Indicated States" on page 9.

This alarm output stops static elimination.

■ 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.

This alarm output will not stop static elimination. Be sure to turn the power OFF

before starting maintenance on the electrode needles.

Once the alarm has been output, it will not automatically stop unless the power or

static elimination has been turned off.

About Display Function

■ Condition alarm output function

This function causes the condition alarm output indicator to blink and an alarm signal (control output

[N.O.]) to output when ions are being absorbed by surrounding metal objects or when static elimination

performance is influenced by the installation environment (temperature, humidity, surrounding metal

objects, etc.).

The display and output of condition alarm are automatically turned off when the

cause of the alarm condition is removed.

4-1 About Maintenance

Maintenance must be performed periodically to ensure that the static elimination performance of the

SJ-F031/036 is fully demonstrated. For maintenance, be sure to thoroughly read the descriptions under

"Safety Precautions" (page 1), and pay attention to the following points.

About Maintenance

• The SJ-F031/036 uses high voltage. Before starting maintenance, be sure to

turn the power OFF. Failure to do so may result in electric shock or

malfunction.

• Do not directly touch the electrode needles.

Take care not to touch these needles even if

the power is turned OFF. Directly touching

these needles may cause personal injury.

When the SJ-F031/036 is used for a long period of time, the electrode needles become dirty due to the

adhesion of dust and dirt.

If the ion level alarm indicator blinks, clean the electrode needles. If the electrode needles are used in a

dirty or dusty state, the static elimination performance can no longer be fully demonstrated, resulting in

accidents or malfunction. We recommend periodically cleaning the electrode needles (as a guideline,

once every two weeks in a regular operating environment though this depends on the installation

conditions).

If cleaning the electrode needles does not improve the static elimination performance, or the ion level

alarm indicator frequently blinks, replace the Electrode Unit.
