Indicators

SJ-HSeries SJ-HASeries SJ-HVSeries SJ-HCSeries

The target's static charge and the quantity of ions generated from the static elimination bar are displayed on the ION MONITOR.

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.

				Middle
OFF	OFF	Yellow
				Low
OFF	OFF	Green
OFF	Green	OFF
				Low
Green	OFF	OFF
				Middle
Yellow	OFF	OFF
				High
Red	OFF	OFF	Negatively charged object

Ion quantity indicator

The ION MONITOR works as an ion quantity indicator as well, and continuously monitors the quantity of ions generated from the static elimination bar and displays the measurement in the colors of the LED.

When leftmost and rightmost indicators are illuminated green, it means that on the SJ-H* Series is fully generating ions. * This cannot be used on the SJ-HA Series.

ION MONITOR	Condition

	Red	Red	OFF
Alarm output function				SJ-HSeries SJ-HASeries SJ-HVSeries SJ-HCSeries

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-H* 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. By using the SJ-H01 Remote Control Console, the warning output can be adjusted in four levels according to the quantity of ions generated. (The warning output cannot be adjusted on the SJ-HA Series).

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. By using the SJ-H01 Remote Control Console, the warning output can be adjusted in four levels according to the installation environment. (The warning output cannot be adjusted on the SJ-HA Series)

For the purpose of energy saving, by short-circuiting the blue (DC GND wire) and pink (static elimination interruption input signal wire) wire terminals of the 10-pin I/O cable, only the static elimination function will be turned OFF without turning off the SJ-H* Series.

Air-purge function

SJ-HSeries SJ-HASeries SJ-HVSeries SJ-HCSeries

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-H* Series in an enclosed space.

Caution • 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-H036*/060*/084*/108*/132*/ 156*/180*/204*.

•Be sure to supply air from both sides (3 locations) of the SJ-H228*/252*/300*.

Provide clean, dry air free of organic matter at a condensation point of -25 °C and approximately 0.01 μm in mesh size.

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 • 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-H036*/060*/084*/108*/132*/ 156*/180*/204*.

•Be sure to supply air from both sides (3 locations) of the SJ-H228*/252*/300*.

Recommended joint

The recommended joint is the Tube Fitting (tube diameter : φ 8 mm) manufactured by Pisco Co.

Tube diameter φ 8 mm : PC8-01

NOTE	• Use a joint having a tube diameter of 8 mm on the SJ-H* Series.

•When providing air to more than one SJ-H* unit, check that each static elimination bar is provided with air. If the air supply source is one, each static elimination bar may not be provided with enough air.

Air booster

SJ-HSeries SJ-HASeries SJ-HVSeries SJ-HCSeries

An optional air booster can be mounted to the SJ-H Series.

By using the air booster, the static elimination speed can be improved and the static elimination range can be expanded.

For more details, see the air booster Instruction Manual.

*The air booster cannot be used with SJ-HA/SJ-HV/SJ-HC Series.

*Please contact the nearest KEYENCE office when using the air-purge function with intermittent air supply.
