Chapter 2 Before Using This Device

2-1 Part Description

It emits light to the receiver facing it. Furthermore, the status of the emitter and the receiver is

indicated on its display section.

It receives light from the emitter facing it. Simultaneously, it turns ON the control output

(OSSD 1 / 2) when the all beam channels receive light from emitter, and it turns OFF the

control output (OSSD 1 / 2) when one or more beam channels are blocked light. Besides, the

receiver displays its status on the display section.

The light emitting elements of the emitter and the light receiving elements of the receiver are

placed at the following intervals, 20mm (SF2B-H□SL) and 40mm (SF2B-A□SL).

This bracket is to be used for mounting the emitter / receiver. It enables to adjust the

horizontal mounting angle using the standard mounting bracket.

This bracket is to be used for mounting the device. SF2B-H□SL is for the device having 40

beam channels or more, SF2B-A□SL is for 20 beam channels or more.

- 10 -

Notes: 1) Since the color of the operation indicator changes according to ON / OFF status of the control output (OSSD

1 / 2), the operation indicator is marked as ‘OSSD’ on the device.

2) The threshold where the control output (OSSD 1 / 2) changes from OFF to ON is applied as ‘100% incident

beam intensity’.

3) The status ‘when light is blocked’ refers to the status that the some obstacle is existed in the sensing area.

4) The description given in [ ] is marked on the device.

2-2 Mounting

2-2-1 Mounting of the Mounting Bracket

•

Mount the emitter and the receiver at the same level and parallel to each other. The effective

aperture angle of this device is ±5° or less for a sensing distance of 3m or more.

•Unless otherwise specified, the following mounting procedure is common for both emitter and

receiver. For the mounting, prepare the mounting holes on the mounting surface by referring to

‘3-2 Dimensions’.

Configuration

The standard mounting bracket (MS-SF2B-1) (optional) configures as follows.

1. Fix the standard mounting bracket with two hexagon-socket head bolts [M3 (length:

5mm)]. The tightening torque should be 0.6N·m or less.

2. For side mounting, remove the B part.

•For selecting the appropriate mounting bracket matched to the installation

environment, the mounting bracket is not incorporated in this device. Please

purchase the optional mounting bracket to fit on the mounting environment.

•

Do not apply the load such as forced bending to the cable of this device.

Applying improper load could cause the wire breakage.

•The minimum bending radius of the cable i

s R6mm. Mount the device

considering the cable bending radius.

- 12 -

3. Mount the brackets so that the protrusion of theA part and the B part are overlapped.

B part to be attached to the top or bottom side of this device differs depending on the

direction of mounting described as the following chart.

4. Mount the mounting bracket on to the mounting surface with two hexagon-socket head

bolts [M5 (please arrange separately)] temporarily.

5. Adjust the height of the emitter and the receiver to level with the elongate holes and then

tighten the hexagon-socket head bolts.

Note: For the models that the intermediate supporting bracket (MS-SF2B-2) is enclosed with, be sure to use

the intermediate supporting bracket (MS-SF2B-2). For details, refer to <When the intermediate

mounting bracket (MS-SF2B-2) (accessory) is used>.

Configuration

The intermediate mounting bracket (accessory) configures as follows.

1. Hook the C part into the groove on the side of the body and press it.

Note that the position to fit the C part onto the main body differs from the surface where

the intermediate mounting bracket is fit.

Insert a flathead screwdriver into the hole located on the rear side of the C part and tilt it to

the rear side of the main body to remove the C part.

- 14 -

2. Insert the D part or E part into the C part in the step 1 condition.

3. Mount the D part or E part on to the mounting surface with the two hexagon-socket head

bolts [M5 (please arrange separately)].

2-2-2 Mounting of the Connector for Series Connection (Optional)

For constructing the series connection, the following procedure is required.

1. Loosen the two M3 screws of the end cap on the main sensor (SF2B-□), and then remove

the end cap from the device.

2. Insert the cable for the series connection (SF2B-CSL□) into the connector of the main

sensor (SF2B-□) and the sub sensor (this device). When inserting the connector, fit the

cable into the groove of the main sensor (SF2B-□) and the sub sensor (this device).

3. Tighten each two M3 screws. The tightening torque should be 0.3N·m or less.

Do not lose any screws during extension / dismantling work.

Furthermore, do not mix emitters and receivers to mount in series connection

The packing is attached to the connector of the bottom cap cable. If the packing is

not attached correct

ly, reattach the packing as shown in the figure below, and

mount to this device.

- 16 -

There is no difference in the cable for series connection for the emitter and the receiver.

The length of the cable for series connection differs depending on the model No.

Model No.

Cable Length (m)

SF2B-CSL01

0.1

SF2B-CSL05

0.5

1. For dismantling the cable for series connection, follow the above procedure of

<Constructing method for the series connection> in reverse.

•The cable for series connection (SF2B-CSL□) cannot be extended.

•When the cable for series connection (SF2B-CSL□) is inserted to the main

sensor (SF2B-□) and the sub sensor (this device), take care of the following.

If inserted without care, the connector pins may bend.

1) Do not pull the cables before tightening the M3 screws.

2) Do not insert the connector incorrectly and tighten the M3 screws.

2-3 Wiring

SF2B-H□: Connectable up to 3 sets of the devices (128 beam channels max.).

SF2B-A□: Connectable up to 3 sets of the devices (64 beam channels max.,

however, when 2 sets are connected, 96 beam channels max.).

This is the configuration for connecting multiple sets of emitters and receivers facing each

other in series. It is used when the dangerous part can be entered from two or more

directions. If any of the sets is in light blocked status, the control output (OSSD 1 / 2) turns

OFF.

For series connection, the cable for series connection (SF2B-CSL□) is required separately.

The wiring method depends on the type of bottom cap cable. Refer to ‘Instruction Manual for

SF2B Series’ for the details of wiring.

When SF2B-H□and SF2B-A□are combined in series connection, double the

number of the beam channels of SF2B-A□to calculate the total number of beam

channels, which should be 128 or less.

<e.g.> The total number of beam channels for SF2B-H36 and SF2B-A44SL is 124.

The number of beam channels of SF2B-H36 +(the number of beam

channels of SF2B-A44SL x2) = Total number of beam channels

36 beam channels + (44 beam channels x 2) = 124 beam channels

Connect the emitter of this main sensor (SF2B-□) and the emitter of the sub sensor

(this device), the receiver of this main sensor (SF2B-□) and the receiver of the sub

sensor (this device) respectively using the exclusive cable (SF2B-CSL□). Wrong

connection could generate the non-

sensing area, resulting in death or serious

injury.

- 18 -

•As the connector for series connection

is not incorporated in the main sensor

such as SF2B-H8□or SF2B-A4□, it

cannot be connected in series.

•The connector for series connection is

not incorporated in the sub sensors

such as SF2B-H8SL or SF2B-A4SL.

In case of connecting three sets of the

devices in series, it cannot be used in

the middle position.

2-4 Adjustment

In case of series connection, if any of the sets is in light blocked status, the control output

(OSSD 1 / 2) turns OFF.

The emitter / receiver indicators indicate the output status.

The following figure shows the status of the indicators with Sub Sensor 2 (this device) in light

blocked status.
