Safety Precautions

■ General Cautions

Danger

■ Precautions for handling the air booster

Danger

• We recommend that you take substantial safety measures to avoid any damage in the event of a problem occurring.

•

Do not modify the product or use it in any way other than described in the specifications.

• Do not use the air booster for the purpose of protecting the human body.

When supplying nitrogen-rich air to a sealed location, the oxygen levels become low, which can cause injury. Always use ventilation when using in a sealed location.

Danger

Caution

When supplying nitrogen-rich air to a sealed location, the oxygen levels become low, which can cause injury. Always use ventilation when using in a sealed location.

When setting on SJ-H060/084/108/132/156/180/204/228/252/300, secure the intermediate support with a screw to prevent twisting. Otherwise, product damage will result.

■ Mounting the air booster

1 Combine the air booster side support with the air booster end unit.

Put together one set (for the left and for the right).

Air booster side support A

2 Mount the air booster side support A and end unit that were

combined in Step 1 to the cable connection side of the static elimination bar.

Note

Always mount the air booster side support A to the modular side. Also, mount air booster side support A first, and then mount air booster side support B last.

3 Mount the air booster 036 conversion part to the static

elimination bar.

Note

When using a static elimination bar model other than SJ-H036, the "Air booster 036 conversion part" is not needed.

Warning

Use earplugs or similar protective devices during use to protect against high noise.

System Configuration

This section describes the name of air booster parts.

Straight air booster starter unit Wide angle booster starter unit (SJ-HS01) (SJ-HW01)

Straight air booster expansion unit Wide angle booster expansion unit (SJ-HS02) (SJ-HW02)

Air booster sealing extension unit Air booster side support A/B (SJ-HM01) (Included with starter unit)

Air booster side support A

Air booster 036 conversion part Air booster sealing cap

(Included with starter unit) (supplied with the wide angle booster starter

unit and the wide angle booster expansion unit)

Air booster side support B

4 Mount the straight air booster (or wide angle booster) unit to the

static elimination bar.

A click can be heard when the part is mounted correctly.

Note

For models other than SJ-H036, the optional straight air booster (or wide angle booster) extension unit is required.

Important

When mounting with the wide angle booster, remove the acceleration electrode probe and attach the air booster sealing cap.

5 Mount the air booster side support B and end unit that

were combined in Step 1.

6 Mount the air booster intermediate support to the

static elimination bar.

Mount air booster intermediate supports to all static elimination bars except for the SJ-H036 model. The required number of air booster intermediate supports is different depending on the model of the static elimination bar being used.

Caution

Be sure to mount the specified number of the air booster intermediate support to SJ-H060/084/108/132/156/180/204/228/252/300.

7 Use M5 screws to secure the SJ-H Series in the

]

installation location.

Note

Be sure to secure the end unit with four M5 screws.

■ Removing the air booster

1 Remove the air booster side support B.

2 Remove the straight air booster (wide angle booster)

through the groove on the static elimination bar guide rail.

The straight air booster (wide angle booster) can

Reference

be removed as a single unit by using a narrow, slotted screwdriver or similar small tool to unlock the lock.

3 Remove the air booster side support A.

■ Supplying air

As shown in the diagram below, install the joint to the air supply opening in order to supply air.

Caution

Recommended joint We recommend using the tube fitting (tube diameter φ10 mm) joint manufactured by Nihon Pisco.

Note

• Be sure to use a joint tightening torque of 1.2 N•m (12 kgf•cm) or less. Otherwise an accident or malfunction may result.

• Be sure to supply air from both sides (2 locations).

•

Please contact the nearest KEYENCE office when opening and closing the air duct.

Tube diameter φ10mm: PC10-03

• Use a joint with a tube diameter of φ10 mm for the air booster.

• When supplying air to multiple units at the same time, supply air to each air booster. If an attempt is made to supply air to multiple SJ-H Series unit from one air supply source, sufficient air supply may not be obtained.
