Make sure to test the operation of the F3SJ-B after installation to verify that the F3SJ-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-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-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-B cannot protect a person from a projectile exiting the hazardous zone. Install protective cover(s) or fence(s).

Install the F3SJ-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 23.

When using more than one set of F3SJ-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-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.

Page 8

Introduction

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

For wiring

Connect the load between the output and +24 V line (NPN output). Connecting the load between the output and 0 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 0 V line. Otherwise, the output is always ON. Also, the +24 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-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.

For the F3SJ-B to comply with IEC 61496-1 and UL 508, the DC power supply unit must satisfy all of the following conditions:

• Must be within the rated power voltage (24 VDC

± 20%)

• Must have tolerance against the total rated current of devices if it is connected to multiple

devices

• Must comply with EMC directives (industrial environment)

• Double or reinforced insulation must be applied between the primary and secondary circuits

• Automatic recovery of overcurrent protection characteristics

• Output holding time must be 20 ms or longer

• Must satisfy output characteristic requirements for class 2 circuit or limited voltage current circuit

defined by UL 508. Refer to p.65 for details.

• Must comply with laws and regulations, regarding EMC and electrical equipment safety, of the

country or region where the F3SJ-B is used (Ex: In EU, the power supply must comply with the EMC Directive and the Low Voltage Directive.)

Double or reinforced insulation from hazardous voltage must be applied to all input and output lines. Failure to do so may result in electric shock.

Extension of the cable must be within a specified length. If it isn't, safety function may not work properly, resulting in danger.

Wiring/Installation

The hazardous zone of a machine can be reached only by passing through the sensor's detection zone.

While working, a person is inside the sensor's detection zone.

It is possible to reach the hazardous zone of a machine without passing through the sensor's detection zone.

A person is between the sensor's detection zone and the hazardous zone of a machine.

Installation Conditions

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-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-B in PSDI mode (Reinitiation of cyclic operation by the protective equipment), you must configure an appropriate circuit between the F3SJ-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-B in environments where flammable or explosive gases are present. Doing so may cause an explosion.

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

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

Hazard

Safety distance (S)

 Safety Distance

The safety distance is the distance that must be set between the F3SJ-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-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-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-B

•C: Additional distance calculated by the detection capability of the F3SJ-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-B from ON to OFF (s)

•d = Detection capability of the F3SJ-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.

or Cro are between two values of this table, the greater safety distance shall be used.

Chapter3 Installation Conditions

[Calculation example]

•T: Tm + Ts (s)

•Tm: Machine's response time (s)

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

• a: Height of machine hazardous zone (mm)

• b: Height of upper edge of detection zone (mm)

When Tm = 0.05 s, Ts = 0.01 s, a = 1,400 mm, b = 1,500 m: From the table above, Cro = 850 mm. Since b is between 1,400 mm and 1,600 mm, b = 1,400 mm which has the greater Cro value, shall be used. S = 2,000 mm/s × (0.05 s + 0.01 s) + 850 mm = 970 mm Since 970 mm is greater than 500 mm, use K = 1,600 mm/s and recalculate it. S = 1,600 m/s × (0.05 s + 0.01 s) + 850 mm = 946 mm

Compare S = 946 mm with the calculation in "If a person approaches the detection zone of the F3SJ perpendicularly", and choose the larger value as the safety distance. For the system with a detection capability of 40 mm max., the safety distance S is 946 mm since this is larger than S = 120 mm calculated in the calculation example of "If a person approaches the detection zone of the F3SJ perpendicularly". For the system with a detection capability larger than 40 mm, the safety distance S is 946 mm since this is the same value as S = 946 mm calculated in the calculation example of "If a person approaches the detection zone of the F3SJ perpendicularly".

Safety distance (S)

If a person approaches the detection zone of the F3SJ-B horizontally

Use K = 1,600 mm/s and C = (1200 - 0.4 x H) in formula (1) for calculation. Note that C must not be less than 850 mm. S = 1,600 mm/s x (Tm + Ts) + 1200 - 0.4 x H

•S = Safety distance (mm)

•Tm = Machine's response time (s)

•Ts = Response time of the F3SJ-B from ON to

Chapter3 Installation Conditions

OFF (s)

•H = Installation height of the F3SJ-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-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-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-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

After installation, the highest level administrator must use the following checklist to verify the operation, placing a check mark in each of the boxes.

 Checklists

 Installation condition check

 The machine itself does not prevent the operation of safety functions such as stopping.  The hazardous part of a machine cannot be reached without passing through the detection zone of

the F3SJ-B.

 The system is configured so that the F3SJ-B can always detect a worker who is working in the

hazardous zone.

 The interlock reset switch is installed in a location that provides a clear view of the entire hazardous

zone and it cannot be activated from within the hazardous zone.

 Safety distance has been calculated. Calculated distance: S = ( ) mm  The actual distance is equal to or greater than the calculated distance. Actual distance = ( ) mm  Reflective surfaces are not installed in prohibited zones.  Not installed in a reflective configuration.  Not used in flammable or explosive atmosphere.

 Wiring check before power is turned ON

Sharing the power supply with other devices may cause the

voltage drop. It is recommended that this safety component use a dedicated power supply but do not share with other devices.

The power supply unit provides 24 VDC while complying with the EMC Directive, Low Voltage

Directive, output holding specification.

The power supply polarity is not connected in reverse. Emitter/receiver cables are properly connected to the respective emitters/receivers. Double insulation is provided between input/output and hazardous voltage (commercial power

source, etc.).

Outputs are not short-circuited to 0 V line. Loads are not connected to the 0 V line. All lines are not connected to commercial power source. Model of emitter and receiver must be the same. When two or more sets of F3SJ-Bs are used, they are series-connected or mutual interference

prevention measures are taken.

When 2 or more sets of F3SJ-B are used in series connection, they must not be connected to a sensor

other than F3SJ-B-T.

A cap is attached to the secondary sensor that is located farthest from the power supply. Neither connector nor bracket must be loose. Auxiliary output must not be used as safety output. Power supply's +24 V must be grounded. Wiring must not be bent, cracked, nor damaged.

In addition to inspection item at operation start, following items must also be verified.

The outputs of the F3SJ-B and the machine are properly wired. The total number of times that the control relays/contactors have switched is significantly lower than

their design lives.

There is no disturbance light. When an F3SJ-B is connected again, the cap is attached to the secondary sensor that is located

farthest from the power supply.

Power supply's +24 V must be grounded. Wiring must not be bent, cracked, nor damaged.

Troubleshooting

Lockout State



If any error is detected that prevents F3SJ-E/B to continue normal operation, it keeps safety output OFF and transitions to lockout state. Under lockout state, the lockout indicators blink or are ON and other indicators blink based on the failure. Perform actions based on the Troubleshooting described later. Eliminate the cause of the problem. Then turn the power ON again or reset the lockout state by providing a reset input to restart the F3SJ-B.

 Warning View

If an abnormality is detected that prevents F3SJ-E/B to continue normal operation, STB or MUTING ERROR indicator is blinked to notify warning information based on the details of the abnormality. F3SJE/B continues normal operation. Perform actions based on the Troubleshooting described later.

Under the manual reset mode, F3SJ-E/B keeps control output OFF. Input the reset signal to release the Interlock state.
