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 serious injury or death.

 

Do not use any reflection type or recursive reflection type arrangement.

 

When connecting the sensor, use the correct combination of emitter and receiver (same beam pitch and number of beam channels) and match their top-bottom orientation. Combining different types of emitter and receiver could produce a non-sensing area, which ma result in serious injury or death.

 

Furthermore, facing several receivers towards one emitter, or vice versa, could produce a non-sensing area or cause mutual interference, which may result in serious injury or death.

The sensing area is the zone formed by the sensing height of the sensor and the sensing range between the emitter and the receiver. The sensing height is determined by the number of beam channels. Furthermore, the sensing range can be 0.3 to 9m for 64 beam channels) and and

2-3-2 Safety Distance

Calculate the safety distance correctly, and always maintain the distance which is equal to o 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 sufficient distance is no maintained, the machine will not stop quickly before reaching to the dangerous parts, which can result in serious injury or death.

The safety distance is the minimum distance that must be maintained between the light curtain 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 area sensor.

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, specification 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 hal signal from this device to the point that the dangerous part of the machine stops. The max. response time of the machine should be timed with the machine to be actually used.

[Standards for power press machine structure] <Safety distance (reference)>

The following formula is for the safety distance given in the ‘Standards for power press machine structure’ (Ministry of Health, Labor and Welfare Notice No.116, issued December 26,

1977) based on the Industrial Safety and Health Law Provision 44. The following example should be considered a reference value. When actually installing the light type press machine safety equipment at the press machine, follow the ‘Standards for power press machine structure’.

Formula (from Standards for power press machine structure, Provision 50) D = 1.6 x (T

In the above formula, D, T

+ TS)

and TS respectively indicate the following values.

D : Distance between light type press machine safety equipment's beam-axis and danger limit

(danger source) (mm)

: Time from shielding of light to operation of press machine's sudden halting mechanism

[The device delay time (14ms)]

: Time from start of press machine's sudden stop mechanism to stop of slide (ms)

The safety distance (D) is calculated from the formula to determine the installation distance (A). If the distance between the beam-axis and bolster front line exceeds a horizontal distance of 400mm, or if the distance is shorter than 400mm but the operator could enter between the beam channels and bolster front line, install the auxiliary beam channels or an additional guard.

Setting the press machine's maximum stop time to 200ms. D = 1.6 x (200 + 14)

= 342.4 (mm)

The safety distance in this case is D = 342.4 (mm).

Connecting the devices used for the main beam channels and auxiliary beam channels serially is recommended. A series connection can prevent mutual interference. (1) If installing the auxiliary beam channels when there is space between the main beam

channels radiated on the light type press machine safety equipment, installed with the safety distance, and the bolster front line in which the operator could enter, install so that the horizontal distance between the main beam channels and auxiliary beam channels is 200mm or less, and so that the horizontal distance between the bolster and the auxiliary beam channels closest to the bolster is 200mm or less.

(2) Install the auxiliary beam channels so that it is horizontal to the bolster's front line, and so that

it is at a point approximately the same as the operator's waist.

[When this device is used as a safety equipment for press machines in Japan]



The emitter and receiver set installed to directly protect the total length of the press machine's stroke length and slide adjustment range is called the ‘main beam channels’. Other emitters and receivers installed for other purposes are called the ‘auxiliary beam channels’. When installing this device as the main beam channels, the beam channels with a protective height larger than the total length of the press machine's stroke length and slide adjustment range must be selected. If the distance between the center of the main beam channels and the bolster front line is 400mm or more, the auxiliary beam channels must be installed at 200mm intervals between the main beam channels and bolster to prevent operators from entering the area. Refer to ‘Policy on Press Machine Safety Equipment Control’ (Ministry of Health, Labor and Welfare, Basic Publication No.446-2, issued on July 9, 1993) for details.

When using the auxiliary beam channels, set the auxiliary beam channels so that the machine operator cannot stand between the machine and this device, and so that the operator cannot go past this device's protective range and enter the machine's dangerous areas. Failure to use an auxiliary beam channels could result in death or serious injury.

Since the receiver performs the self-diagnosis of the output circuit when the sensor is in light receiving status (ON status), the output transistor becomes OFF status periodically. (Refer to the figure below.) When the OFF signal is fed back, the receiver judges the output circuit as normal. When the OFF signal is not fed back, the receiver judges either the output circuit or wiring as error, and the control output (OSSD 1, OSSD 2) maintains OFF status.

Since the OFF signal of this device might cause malfunction, perform the connecting paying attention to the input response time of the machine to be connected to this device.

2-5-3 Wiring㨯Connecting Procedure and Connector Pin Arrangement

Connect the mating cable (with connector on one end, or connector on both ends) to the connector of the sensor main body (emitter and receiver). Wire the other side of the mating cable according to the customer’s application referring to the connector pin arrangement given below.

 

When extending the cable, use the exclusive cable up to the total length of 50m (for emitte / receiver). Extending the cable longer than 50m may cause malfunction, which can resul in serious injury or death. Besides, if the 2 sets of the sensors are connected in series, up to total length of 30m (for emitter / receiver) is allowed for use, and if the 3 sets of the sensors are connected, up to total length of 20m (for emitter / receiver) is allowed for use. Extending the cable longer than the length specified may cause malfunction, which can result in serious injury or death.

 

In case the muting lamp is used, a total length should be 40m or less. (for emitter / receiver)

 

When the synchronization cable is extended with a cable other than exclusive cable, use a

0.2mm2 or more shielded twist pare cable.

When this device is used as safety equipment for press machines, be sure to use th cable with protective tube (

The beam-axis alignment indicator indicates the reception status for each section of a sensor which is divided into 4 sections. Also, the A (D) of the beam-axis alignment indicates the light-receiving status of the sensor top end (bottom end). For example, when using a 24-beam channel sensor, there are 6 beam channels per section (i.e., 24/4=6). When the top end (bottom end) beam channel is received, the A (D) of the beam-axis alignment indicator blinks in red. (Example) 24 beam channels

When using this device as safety equipment for press machines in Japan, always observe the following items and correctly use the device.

Secure a safety distance according to the maximum stopping time of the press machine. Start the press machine, and confirm that the slide stops when the light is blocked. Make sure that the receiver is not subject to direct sunlight. When using an ‘rise disabled circuit’ having a function that does not suddenly stop the slide

even if the light is blocked while the slide is rising (the muting function), make sure that the safety equipment is enabled when the slide is going down and is disabled only when rising.

Adjust the emitter, receiver and reflective plates so that none of the operator body parts,

depending on the work or work posture, etc., could enter the danger areas from either above the uppermost beam channel or below the lowermost beam channel.

Refer to ‘Policy on Press Machine Safety Equipment Control’ (Ministry of Health, Labor and Welfare, Basic Publication No.446-2, issued on July 9, 1993) for details.

The abbreviation for Output Signal Switching Device. A component of the light curtain that turns off when light of the light curtain is blocked.

The component of the machine’s safety related control system that open-circuits the MPCE circuit when the OSSD operates due to the light from the light curtain being blocked.

Test rod This is a rod for checking the detection capability of this device. It has di-

mensions corresponding to the minimum sensing object for this device.

Main side / Sub side For series connection, the side where the power supply or the output is

connected is called the main side, and the others are called the sub side.

Lockout It is one of the safe status of this device. Operation is stopped if the

self-diagnosis function determines that an irrecoverable failure (OSSDs do not operate normally, etc.) has occurred. If an emitter is in lockout condition, it will stop emitting light. If a receiver is in lockout condition, OSSDs are turned OFF.

Safety distance It is the minimum distance that must be maintained between the light cur-

tain and the dangerous parts of a machine so that the machine can be stopped before a human body or an object can reach the dangerous parts.

Protective height (Sensing height)

The length of the beam axis direction that the min. sensing object can be detected. The length from the center of the first beam channel to the center of the last beam channel in addition to +10mm (+5mm upward, +5mm downward). [However, if this device is used as safety equipment for press machines in Japan, the protective height should be the from the center of the first beam channel to the centre of the last beam channel.]

Sensing range It is the range between the facing emitter and receiver.

Sensing area It is the area over which intrusion by people or objects can be detected by

one set of sensor. It is given by the product of the protective height and the operating range.

Emission halt function

This function enables checking of the receiver operation by turning off light emission. It is possible to halt emission by keeping the terminal open, and to have normal emission by connecting it to -V (+V for NPN output).

PSDI The abbreviation for the Presence Sensing Device Initiation.

The safety device that restarts automatically without any operation by the operator after the device detects danger status and halts for a while.
