Other Functions
This section describes other functions such as the display function, alarm output function, and air
purge function.
Indicators
The target's static charge and the quantity of ions generated from the static elimination bar are displayed on the ION MONITOR.
Air-purge function
Supplying clean air through the air duct on both ends of the static elimination bar will prevent the dust
accumulation on the electrode probes. The air purge widens the static elimination area and increases
the speed of static elimination as well.
* The air pressure indicates the pneumatic value at the route of the joint.
*
Please contact the nearest KEYENCE office when using the air-purge function with intermittent air supply.
Danger
Filling a closed space with nitrogen will reduce the oxygen levels in the air to dangerous
levels.
Make sure that there is adequate ventilation when using the SJ-HA Series in an enclosed
space.
■ Electric charge indicator
The ION MONITOR works as an electric charge indicator that displays the target's static charge,
polarity of the static charge, and condition of static elimination.
The plus and minus side LEDs will illuminate in response to the current charge level.
When static elimination is finished, the indicator in the middle will be illuminated. Therefore, the user
will know the process of static elimination.

Alarm output function
■ Alarm function (ALM)
The ION/ALM/COND indicator will flash red three times per second and
an alarm signal (N.C. control signal) will be output if the internal circuit
is damaged or an abnormal electrical discharge occurs.
Then the SJ-HA Series will stop generating ions.
Alarm output will activate regardless of whether or not static elimination
is being interrupted manually or forcibly.
■ Ion level alarm function (ION)
The ION/ALM/COND indicator will flash twice per second and an alarm
signal (N.O. control signal) will be output if the quantity of ion generation is low due to the deterioration of the electrode probes or the dirt on the electrode probes. Static elimination will not be interrupted in this case.
The ion level warning can be a notice for the maintenance of the electromagnetic probes. Static elimination continues, so make sure to turn off the power when you perform maintenance on the electromagnetic probes.
■ Condition alarm function (COND)
The ION/ALM/COND indicator will flash once per second and an alarm signal (N.O. control signal)
will be output if the installation environmental conditions (e.g., the temperature, humidity, and ambient
metal) are unstable and likely to affect the performance of static elimination adversely (e.g., the
absorption of ions) caused by ambient metal objects. Static elimination will not be interrupted in this
case.
Caution
Provide clean, dry air free of organic matter at a condensation point of -25 °C and approximately 0.01
μm in mesh size.
• Check that the air pressure does not exceed 0.5 MPa, otherwise an accident or malfunction may result.
• Please contact the nearest KEYENCE office when opening and closing the air duct.
• Be sure to provide clean, dry air to the static elimination bar. If the air contains water or oil,
air leaks or electrical discharges may occur in the static elimination bar, thus resulting in
accidents or malfunctions.
• Be sure to supply air from both sides (2 locations) of the SJ-H036A/060A/084A/108A/
132A/156A/180A/204A.
• Be sure to supply air from both sides (3 locations) of the SJ-H228A/252A/300A.
■ Air supply method
As shown in the illustration below, remove the screw that block the air duct on either end of the static
elimination bar, connect a joint to the air duct, and provide air.
Caution
Recommended joint
The recommended joint is the Tube Fitting (tube diameter : φ 8 mm) manufactured by Pisco Co.
NOTE
• Be sure to limit the tightening torque to 1.2 N•m (12 kg•cm2) or less. Otherwise, an accident or product breakdown may occur.
• Be sure to supply only clean, dry air. The use of improper air may cause an accident or
product malfunctions.
• Be sure to supply air from both sides (2 locations) of the SJ-H036A/060A/084A/108A/
132A/156A/180A/204A.
