Position with detection zone bent at 90°

Reflector

Make sure to test the operation of the F3SJ-E/B after installation to verify that the F3SJ-E/B operates as intended. Make sure to stop the machine until the test is complete. Unintended function settings may cause a person to go undetected, resulting in serious injury.

Make sure to install the F3SJ-E/B at the safe distance from the hazardous part of the equipment. Otherwise, the machine may not stop before a person reaches the hazardous part, resulting in serious injury.

Install a protective structure so that the hazardous part of a machine can only be reached by a person that passes through the sensor's detection zone. Install the sensors so that part of the person is always present in the detection zone when working in a machine's hazardous zones, eliminating areas where the sensors do not reach. If a person is able step into the hazardous zone of a machine and remain behind the F3SJ-E/B's detection zone, configure the system with an interlock function that prevents the machine from being restarted. Failure to do so may result in serious injury.

Install the interlock reset switch in a location that provides a clear view of the entire hazardous zone and where it cannot be activated from within the hazardous zone.

Introduction

The F3SJ-E/B cannot protect a person from a projectile exiting the hazardous zone. Install protective cover(s) or fence(s).

Install the F3SJ-E/B so that it is not affected by a reflective surface. Failure to do so may hinder detection, resulting in serious injury. Details on installation distance from the reflective surface, see "Distance from Reflective Surfaces" on page 41.

When using more than one set of F3SJ-E/Bs, install them so that mutual interference does not occur, such as by configuring series connections or using physical barriers between adjacent sets.

Make sure that the F3SJ-E/B is securely mounted and its cables and connectors are properly secured.

Do not use the sensor system with mirrors in a retro-reflective configuration as shown below. Doing so may hinder detection. It is possible to use mirrors to "bend" the detection zone to a 90degree angle.

F3SJ-E/B

User’s Manual

Page 8

Introduction

Perform an inspection for all F3SJ-E/B as described in "Chapter 5 Checklists".

Install muting sensors so that they can distinguish between the object that is being allowed to be passed through the detection zone and a person. If the muting function is activated by the detection of a person, it may result in serious injury.

Use independent two input devices for muting inputs.

The muting and override functions disable the safety functions of the device. You must ensure safety using other method when these functions are operating.

Install the switch that uses hold-to-run device such as a spring-return key switch and is installed in a location that provides a clear view of the entire hazardous zone and where it cannot be activated from within the hazardous zone. Make sure that nobody is in the hazardous zone before activating the override function.

For wiring

Connect the load between the output and 0 V line (PNP output). Connecting the load between the output and +24 V line will result in a dangerous condition because operation is reversed to "ON when blocked".

Do not short-circuit the output line to the +24 V line. Otherwise, the output is always ON. Also, the 0 V of the power supply must be grounded so that output does not turn ON due to grounding of the output line.

Configure the system by using the optimal number of safety outputs that satisfy the requirements of the necessary safety category.

Do not connect each line of F3SJ-E/B to a DC power supply of more than 24 VDC+20%. Also, do not connect to an AC power supply. Failure to do so may result in electric shock or breakdown of the device.

Make sure to perform wiring while the power supply is OFF.

Do not use the auxiliary output for safety applications. Human body may not be detected when F3SJ-B fails, resulting in serious injury.

The F3SJ-E/B performs the self-test when power is turned ON (within 2 seconds) to check for errors. Also, it regularly performs the self-test (within a response time) while operating. This function cannot be cancelled.

If an error is found in the self-test, the F3SJ-E/B enters lockout state, keeps the safety output in the OFF state, and indicates the error at the same time.

 Self-test details

The self-test detects the types of errors described below. Emitter

• Failure of emitter element or circuit

• CPU failure

• Disconnected or short-circuited cable

Receiver

• Abnormal external power supply voltage

• Failure of internal power supply circuit

• Failure of receiver element or detection circuit

• Incidence of disturbance light

• Failure of safety output circuit

• Disconnected or short-circuited cable

Chapter2 Description of Functions

 Waveform of safety outputs

When the F3SJ-E/B is receiving light, the safety outputs cyclically turn OFF as shown below to test the output circuit. When this OFF signal is fed back, the output circuit is diagnosed as normal. If the output signal does not include an OFF pulse signal due to short-circuit, etc, the receiver diagnoses a failure in the output circuit or wiring, and it enters lockout state.

System Configuration and Functions

The F3SJ-B turns the safety outputs OFF when its power is turned on or its beam is interrupted and holds this state until reset input is applied. This state is called "interlock". Two methods can be used to reset the interlock state: "auto reset" and "manual reset." "Auto reset" automatically turns safety outputs ON when the interrupting object is removed. "Manual reset" keeps safety outputs OFF until a reset signal is provided, if the interrupting object is removed.

 Auto reset

When the interrupting object is removed from the detection zone, the safety outputs automatically turn ON. Auto reset is used on machines where a worker is not able to enter the area between the detection zone and the hazardous part of the machine.

- Wiring for auto reset mode and external device monitoring function p.13

- Wiring for auto reset mode and deactivated external device monitoring function p.14

 Manual reset

When a reset input is given while no interrupting object exists in a detection zone, the safety outputs turn ON. This allows the machine to be manually reset using a reset switch after ensuring safety, preventing unexpected startup (EN 1037).

Chapter2 Description of Functions

There are two types of interlock as follows:

•The power is turned ON (start interlock).This is useful if you want to keep the machine stopped until start inspection is completed after the power is turned ON.

•The F3SJ-B is blocked (restart interlock). After the F3SJ-B is blocked and the machine stops, manual reset is effective when you want to restart the machine after an operator confirms a safe condition.

- Wiring when using manual reset mode and external device monitoring p.12

- Wiring for manual reset mode and deactivated external device monitoring function p.13

To re se t:

1. After applying a voltage of Vs-3 V to Vs for 300 ms or longer to the reset input line, set it to open or to

0 to 1/2 VsV.

Install the interlock reset switch in a location that provides a clear view of the entire hazardous zone and where it cannot be activated from within the hazardous zone.

Basic Type (muting system)

The external device monitoring function cannot be used when the muting system is used. This function detects malfunctions, such as welding, in external relays (or contactors) that control the hazardous part of a machine. This function constantly monitors that a specified voltage is applied to the receiver's external device monitoring input line, and the system enters lockout state when an error occurs. The relay's operational delay can be up to 0.3 s without being evaluated as an error. For example, if the normally closed N.C. contact does not close within 0.3 s after the safety outputs turn from ON to OFF, and a specified voltage is not applied to the external device monitoring line , it is evaluated as an error and the system enters a lockout state. To utilize this function properly, use safety relays and contactors that have force guided or mechanically linked contact structure.

 Wiring

Perform wiring so that a voltage of Vs-3 V to Vs is applied to the external device monitoring line via the external relay's normally closed N.C. contact. When external device monitoring is not being used, apply the auxiliary output to the external device monitoring input.

Wiring for external device monitoring function p.12

 Timing chart

The sensor reads out a device monitoring input value a minimum of 0.5 s after the power of the F3SJB is turned ON. If the status of the safety outputs is changed back to the original status within the allowable delay time, the F3SJ-B will not enter the lockout state.

Chapter2 Description of Functions

Muting function temporarily disables safety function of the F3SJ-B, keeping safety output ON even if beams are interrupted. This makes it possible to install safety light curtains for AGV passage, enabling both safety and productivity. When muting, the top-beam-state indicator (TOP), bottom-beam-state indicator (BTM) and external indicator (if wired) connected to the auxiliary output blink to notify people in the surrounding zone that the safety functions are disabled.

The muting and override functions disable the safety functions of the device. You must ensure safety using other method when these functions are operating.

 Upgrading F3SJ-B for muting system

Loosen two cap screws (M3 cross-shaped) of either an emitter or a receiver to remove the cap. Replace the Cap with a Muting Key Cap and then tighten it with two screws (M3 cross-shaped).

Chapter2 Description of Functions

- When mounting a Cap or Muting Key Cap, securely tighten the screw (M3 cross-shaped) with the recommended torque of 0.54 N•m. Failure to do so may cause the cap to come loose, leading to deterioration of the protective functions.

- Attaching/detaching of a Cap or Muting Key Cap may cause misalignment of rubber grommet in a connector assembly. Press the grommet to the bottom of the connector and attach the connector to the F3SJ-B again.

The muting sensor is the sensor that is the trigger for temporarily disabling the safety functions of the F3SJ-B. You can use a photoelectric switch of transmission type or reflective type proximity switch, or limit switch. (Recommendation: OMRON E3Z series, E2E series (3-wire type), D4N series) Use a 3wire type PNP output or N.O. type contact. Two-wire type sensor cannot be used.

You may need a muting lamp depending on your application or as a result of a risk assessment. Before determining the use of the muting lamp, check laws and regulations of the country or region where the F3SJ-B is used and make sure of full compliance with them. The muting lamp can be connected to the auxiliary output.

 Using muting function

Turning muting inputs 1 and 2 ON sequentially enables muting function. When a muting lamp is required as a result of a risk assessment, connect a muting lamp to the auxiliary output line.

Chapter2 Description of Functions

If both of the following conditions are present for the F3SJ-B, muting is activated.

1. No interrupting object is found in the F3SJ-B's detection zone, and safety output is ON.

2. After muting input 1 is turned ON (connected to Vs-3 V to Vs), muting input 2 is turned ON (connected to Vs-3 V to Vs) within the muting input time limit of T1min to T1max (0.1 to 3 s).

Muting function can be enabled in up to 0.15 s after condition 2 is satisfied. When condition 1 is satisfied but time condition of 2 is not, a muting sequence error occurs and emitter's muting error indicator blinks. However, when there is a muting error, the F3SJ-B safety function operates and normal operation continues.

For muting error indication, see page 121 .

Muting error can be released by any of following conditions:

1. Correct muting initial condition continues for 0.1 s or longer. *1

2. Power cycle under muting input 1 and 2 OFF state.

*1. The correct initial muting condition is shown as follows.

• Safety output of the light curtain is ON.

• Muting input 1 and 2 are OFF.

If either of the following conditions is satisfied, the muting state is released.

1. Muting input 1 or 2 turns OFF for T3 (0.1 s) or longer.

2. The muting continuation time exceeds the muting time limit of T2 (60 s).

•Set the muting sensors so that they can detect all of the passing detection objects (palettes, automobiles, etc.). Do not install in a position so that only the front or rear end of the detection object is detected.

•Set the muting sensors so that they detect the objects even when they are loaded on palettes or other transport devices.

•Also, install the F3SJ-B and muting sensors so that each object passes through all muting sensors before the next object arrives at the first muting sensor. Also, install all F3SJ-Bs and muting sensors so that no person is able to accidentally enter the hazardous zone while the muting function is enabled.

•If objects' speeds can vary, the allocation of muting sensors must be taken into consideration.

•Install muting sensors so that they can distinguish between the object that is being allowed to be passed through the detection zone and a person.

Detection Zone and Approach



Install a protective structure so that the hazardous part of a machine can only be reached by passing through the sensor's detection zone. Install the sensors so that part of the person is always present in the detection zone and no blind spot is generated when working in a machine's hazardous zones.

Chapter3 Installation Conditions

If a person is able to step into the hazardous zone of a machine and remain behind the F3SJ-E/B's detection zone, configure the system with an interlock function that prevents the machine from being restarted. Failure to do so may result in serious injury.

Do not use this sensor for machines that cannot be stopped by electrical control. For example, do not use it for a pressing machine that uses a full-rotation clutch. Otherwise, the machine may not stop before a person reaches the hazardous part, resulting in serious injury.

To use the F3SJ-E/B in PSDI mode (Reinitiation of cyclic operation by the protective equipment), you must configure an appropriate circuit between the F3SJ-E/B and the machine. For details about PSDI, refer to OSHA 1910.217, IEC 61496-1, and other relevant standards and regulations.

Install the interlock reset switch in a location that provides a clear view of the entire hazardous zone and where it cannot be activated from within the hazardous zone.

Do not use the F3SJ-E/B in environments where flammable or explosive gases are present. Doing so may cause an explosion.

The F3SJ-E/B cannot protect a person from a projectile exiting the hazardous zone. Install protective cover(s) or fence(s).

Make sure that the F3SJ-E/B is securely mounted and its cables and connectors are properly secured.

Safety distance (S)

 Safety Distance

The safety distance is the distance that must be set between the F3SJ-E/B and a machine's hazardous part to stop the hazardous part before a person or object reaches it. The safety distance varies according to the standards of each country and the individual specifications of each machine. Always refer to relevant standards.

Make sure to secure the safety distance (S) between the F3SJ-E/B and the hazardous part. Otherwise, the machine may not stop before a person reaches the hazardous part, resulting in serious injury.

The response time of a machine is the time period from when the machine receives a stop signal to when the machine's hazardous part stops. Measure the response time on the actual system. Also, periodically check to make sure that the response time of the machine has not changed.

 How to calculate the safety distance specified by International Standard ISO 13855

(European Standard EN ISO 13855) (Reference)

If a person approaches the detection zone of the F3SJ-E/B perpendicularly S = K x T + C . . . Formula (1)

•S: Safety distance

•K: Approach speed to the detection zone

•T: Total response time of the machine and F3SJ-E/B

•C: Additional distance calculated by the detection capability of the F3SJ-E/B

Chapter3 Installation Conditions

Use K = 2,000 mm/s and C = 8 x (d - 14 mm) in formula (1) for the calculation. S = 2,000 mm/s x (Tm + Ts) + 8 x (d - 14 mm)

•S = Safety distance (mm)

•Tm = Machine's response time (s)

•Ts = Response time of the F3SJ-E/B from ON to OFF (s)

•d = Detection capability of the F3SJ-E/B (mm)

[Calculation example] When Tm = 0.05 s, Ts = 0.015 s, and d = 25 mm: S = 2,000 mm/s x (0.05 s + 0.015 s) + 8 x (25 mm - 14 mm) = 218 mm If the result is less than 100 mm, use S = 100 mm. If the result exceeds 500 mm, use the following formula where K = 1,600 mm/s. S = 1,600 mm/s x (Tm + Ts) + 8 x (d - 14 mm) . . . Formula (2)

If the result of this formula (2) is less than 500 mm, use S = 500 mm.

•H = Installation height of the F3SJ-E/B (mm)

Note that H must satisfy: 1000 >= H >= 15 (d - 50 mm)

Also, you must include a hazardous condition under which a person may go carelessly through under a detection zone if it exceeds 300 mm (200 mm for other purpose than industrial use) into risk assessment.

[Calculation example] When Tm = 0.05 s, Ts = 0.015 s, d = 25 mm, and H = 500 mm: S = 1,600 mm/s x (0.05 s + 0.015 s) + 1200 - 0.4 x 500 mm = 1,104 mm

 How to calculate the safety distance specified by American Standard ANSI B11.19

(reference)

If a person approaches the detection zone of the F3SJ-E/B perpendicularly, calculate the safety distance as shown below. S = K x (Ts + Tc + Tr + Tbm) + Dpf

•S: Safety distance

•K: Approach speed to the detection zone (the value recommended by OSHA standard is 1,600 mm/s)

Approach speed K is not specified in the ANSI B.11.19 standard. To determine the value of K to apply, consider all factors, including the operator's physical ability.

•Ts = Machine's stopping time (s)

•Ts = Response time of the F3SJ-E/B from ON to OFF (s)

•Tc = Machine control circuit's maximum response time required to activate its brake (s)

•Tbm = Additional time (s)

If a machine has a brake monitor, "Tbm = Brake monitor setting time - (Ts + Tc)". If it has no brake monitor, we recommend using 20% or more of (Ts + Tc) as additional time.

•Dpf = Additional distance

According to ANSI's formula, Dpf is calculated as shown below: Dpf = 3.4 x (d - 7.0): Where d is the detection capability of the F3SJ-E/B (unit: mm)

[Calculation example] When K = 1,600 mm/s, Ts + Tc = 0.06 s, brake monitor setting time = 0.1 s, Tr = 0.015 s, and d = 25 mm: Tbm = 0.1 - 0.06 = 0.04 s Dpf = 3.4 x (25 - 7) = 61.2 mm S = 1,600 mm/s x (0.06 s + 0.015 s + 0.04 s) + 61.2 mm = 245.2 mm

 Mutual Interference Prevention

Mutual interference is prevented in up to three sets, using interference light detection and cycle shift algorithm. If four or more sets of F3SJ-E/Bs are installed, arrange them so that mutual interference does not occur. If two sets are installed near each other, reflection from the surface of the F3SJ-E/B may cause mutual interference. When mutual interference occurs, the safety outputs are turned OFF in a moment or the F3SJ-E/B enters lockout state. Combining countermeasures 1 to 3 shown below is effective.

1. Install a physical barrier between two sets
