Do not install this device with a machine whose operation cannot be stopped immediately in the middle of an operation cycle by an emergency stop equipment. This device starts the performance after 2 sec. from the power ON. Have the control system started to function with this timing.

Wiring

Be sure to carry out the wiring in the power supply OFF condition. All electrical wiring should conform to the regional electrical regulations and laws. The wiring should be done by engineer(s) having the special electrical knowledge. Do not run the wires together with high-voltage lines or power lines or put them in the same raceway. This can cause malfunction due to induction. In case of extending the cable of the emitter or the receiver, each can be extended up to 40.5m by using the exclusive cable. Furthermore, if the cable is extended, the muting lamp is used, the total extendable length of the cable. For details, refer to WARNING under “

Procedures and Terminal Arrangement

Do not control the device only at one control output (OSSD 1 / 2). In order that the output is not turned ON due to earth fault of the control output (OSSD 1 / 2) wires, be sure to ground to 0V side (PNP output) / +V side (NPN output).

Protection Area

2-3 Protection Area

2-3-1 Sensing Area

Be sure to install protection structure around the machine so that the operator must pass through the sensing area of this device to reach the dangerous parts of the machine. Furthermore, ensure that some part of the operator’s body always remains in the sensing area when operation is done with the dangerous parts of the machine. Failure to do so can result in death or serious injury. Do not use any re ection type or recursive re ection type arrangement. Furthermore, never use this device facing several receivers towards one emitter or vice versa.

The sensing area is the zone formed by the sensing height (protective height) of the device and the valid range between the emitter and the receiver. The sensing height (protective height) is determined by the number of beam channels. Furthermore, the valid range can be 0.1 to 3m. Take care that if the valid range is under 0.1m, malfunction may occur due to the optical structure.

2-3-2 Safety Distance

Calculate the safety distance correctly, and always maintain the distance which is equal to or greater than the safety distance, between the sensing area of this device and the dangerous parts of the machine. If the safety distance is miscalculated or if suf cient distance is not maintained, the machine will not stop quickly before reaching to the dangerous parts, which can result in death or serious injury.

The safety distance is the minimum distance that must be maintained between this device and the dangerous parts of the machine so that the machine can be stopped before a human body or an object can reach the dangerous parts. The safety distance is calculated based on the equation described in the next page when a person moves perpendicular (normal intrusion) to the sensing area of the device.

Safety distance S

Sensing area

Dangerous part

Intrusion direction

Before designing the system, refer to the relevant standards of the region where this device is to be used, and then install this device. Furthermore, the equation described in the next pages is to be used only in case the intrusion direction is perpendicular to the sensing area. In case the intrusion direction is not perpendicular to the sensing area, be sure to refer to the relevant standard (regional standard, speci cation of the machine, etc.) for details of the calculation.

The max. response time of the machine is from the point that the machine receives the halt signal from this device to the point that the dangerous parts of the machine stops. The max. response time of the machine should be timed with the machine to be actually used.

For calculating the safety distance S, there are the following ve cases. First, calculate by substituting the value K = 2,000 (mm/sec.) in the equation above. Then, classify the obtained value of S into three cases, 1) S < 100, 2) 100 S 500, and 3) S > 500. For Case 3) S > 500, recalculate by substituting the value K = 1,600 (mm/sec.). After that, classify the calculation result into two cases, 4) S 500 and 5) S > 500. For details, refer to “Calculation example 1 For use in Europe.” When this device is used in the “PSDI mode,” an appropriate safety distance S must be calculated.

4) In case S 500 (mm) Safety distance S is taken as 500 (mm)

5) In case S > 500 (mm) Safety distance S is taken as 1,600 × T

+ 99.2 (mm)

In case this device is installed in a system with a maximum halting time 0.1 (sec.)

S = 2,000 × T

+ 102 = 2,000 × 0.1 + 102 = 302

Since this value matches with the case 2) above, S is 302 (mm).

In case this device is installed in a system with a maximum halting time 0.4 (sec.)

= 2,000 × T

+ 102 = 2,000 × 0.4 + 102 = 902

Since this value matches with the case 3) above,

S = 1,600 × T

+ 99.2 = 1,600 × 0.4 + 99.2 = 739.2

Since this value matches with the case 5) above, S is 739.2 (mm).

Equation 2 DS = K × (TS + TC + T

DS : Safety distance (mm) Minimum required distance between the sensing area surface and the dangerous parts of the

machine K : Intrusion speed {Recommended value in OSHA is 63 (inch/sec.) [ 1,600 (mm/sec.)]} ANSI/RIA 15.06 does not de ne the intrusion speed “K”. When determining K, consider pos-

sible factors including physical ability of operators.

Since the calculation above is performed by taking 1 (inch) = 25.4 (mm), there is a slight difference between the representation in (mm) and that in (inch). Refer to the relevant standard for the details.

2-3-3 In uence of Re ective Surfaces

If there exists a re ective surface in the place where this device is to be installed, make sure to install this device so that re ected light from the re ective surface does not enter into the receiver, or take countermeasures such as painting, masking, roughening, or changing the material of the re ective surface, etc. Failure to do so may cause the device not to detect, resulting in death or serious injury.

Install this device at a distance of at 0.16m or more from re ective surfaces such as metal walls, oors, ceilings, sensing objects, covers, panels or glass surfaces.

Refer to the examples of device placement given below and understand them thoroughly before installing the devices. Improper sensor placement could cause device malfunction, which can result in death or serious injury. If this device is used in multiple sets, arrange them to avoid mutual interference. If mutual interference occurs, it can result in death or serious injury.

2-4-1 Mounting of the Mounting Bracket

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 is R6mm. Mount the device with considering the cable bending radius.

Mount the emitter and the receiver at the same level and parallel to each other. The effective aperture angle of this device is ±2.5° or less at a sensing distance of 3m. Unless otherwise speci ed, the following mounting procedure is common for both emitter and receiver. For the preparation of the mounting, prepare the mounting holes on the mounting surface by referring to “

which is attached to this device can be changed de-

pending on the mounting position of the device.

1. Remove the M3 countersunk head screw [with anti-loosening agent (length 4mm)] which is attached to the back of the device.

2 Decide the direction of the standard mounting bracket.

3. Tighten with the M3 countersunk head screw [with anti-loosening agent (length 4mm)].

The tightening torque should be 0.3 N·m.

Wiring

2-5 Wiring

Earth the machine or the support where the device is mounted on to frame ground (F.G.). Failure to do so could cause the malfunction of the product by noise, resulting in death or serious injury. Furthermore, the wiring should be done in a metal box connected to the frame ground (F.G.). Take countermeasure against the system to be applied for this device so as not to carry out the dangerous performance caused by the earth failure. Failure to do so could cause invalid for the system stop, resulting in death or serious injury. In order that the output is not turned ON due to earth fault of the control output (OSSD 1 / 2) wires, be sure to ground to 0V side (PNP output) / +V side (NPN output).

Make sure to insulate the ends of the unused lead wires.

Use a safety relay unit or an equivalent control circuit in safety for FSD.

2-5-1 Power Supply Unit
