For installation

Make sure to test the operation of the F3SJ after installation to verify that the F3SJ 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 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. If a person is able step into the hazardous zone of a machine and remain behind the F3SJ'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.

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

Introduction

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 muting sensors so that they can distinguish between the object that is being allowed to pass 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.

Muting lamps (external indicators) that indicate the state of the muting and override functions must be installed where they are clearly visible to workers from all the operating positions.

Use independent 2 input devices for muting inputs.

You must install F3SJ, muting sensor, and physical barrier so that an operator should not enter hazardous zone.

Install the switch that activates the muting override function 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.

Install the sensor system so that it is not affected by the reflective surface of the F3SJ.

When using more than 1 set of F3SJ, 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 is securely mounted and its cables and connectors are properly secured.

Make sure that foreign material such as water, oil, or dust does not enter the F3SJ or the connector while the cap is removed.

Introduction

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 90-degree angle.

Reflector

Position with retro-reflection

Position with detection zone bent at 90

Perform an inspection for all F3SJ as described in "Chapter 5 Checklists". When using series connections, perform inspections for every connected F3SJ.

For wiring

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

Do not short-circuit the output line to the +24V line. Otherwise, the output is always ON. Also, the 0V 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 to a DC power supply of more than 24VDC+20%. Also, do not connect to an AC power supply. Failure to do so may result in electric shock.

For the F3SJ 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 (24V DC

± 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 (reversed L sagging)

• Output holding time must be 20ms or longer

• Must satisfy output characteristic requirements for class 2 circuit or limited voltage current circuit defined by UL508

• Must comply with laws and regulations, regarding EMC and electrical equipment safety, of the country or region where the F3SJ is used (Ex: In EU, the power supply must comply with the EMC Directive and the Low Voltage Directive.)

 Using Multiple Sets in Combination

By installing sensors on both sides of a machine as well as in front, you can move workpieces in and out more efficiently than when a physical barrier is installed. If the sensors are aligned in a U-shape, series-connection cables can be used between sets (up to 3 sets), so that only one control device is used, drastically reducing the amount of wiring in the panel.

Chapter1 Application Examples

 For a System in which a Workpiece Crosses Detection Zone

(Muting Function)

Enter of a workpiece can be detected by a sensor and the detection zone can be temporarily disabled only while the workpiece is crossing the whole zone. This function is called muting. Muting is when a work piece is allowed to enter into a dangerous zone without tripping the F3SJ and stopping the process. Muting sensors are installed and arranged as to detect the work piece and not a human entering the zone.

 Enhanced Mutual Interference Prevention

When the series connection function is used, mutual interference is prevented in up to 240 beams in 3 sets. When F3SJ are used individually, the newly designed interference light detection and cycle shift algorithm prevents mutual interference in up to 3 sets.

 Muting/Override Function are Provided

An F3SJ by itself can operate with muting or override function without using a controller.

 Waveform of Safety Outputs

When the F3SJ 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, the receiver diagnoses a failure in the output circuit or wiring, and it enters lockout state. (See the table below.)

System Configuration and Functions

 External Device Monitoring Function

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

 Wiring

Perform wiring so that 9 to 24V is applied to the external device monitoring line via the external relay's normally closed (N.C.) contact. When external device monitoring function is not being used, apply auxiliary output 1 to the external device monitoring input.

- Wiring when external device monitoring function is used p.19

- Wiring when external device monitoring function is not used p.20

 Timing Chart

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

Muting System

The muting function temporarily disables the safety function of the F3SJ, keeping the safety outputs ON even if beams are blocked. This makes it possible to install safety light curtains for AGV passage, enabling both safety and productivity. When muting, the muting indicator blinks to notify people in the surrounding zone that the safety functions are disabled.

Chapter2 Muting System

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

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

Muting lamps (external indicators) that indicate the state of the muting and override functions must be installed where they are clearly visible to workers from all the operating positions.

 Upgrading F3SJ for Muting System

1. Remove the caps of the emitter and receiver.(driver comes with key cap for muting)

2. Install a muting lamp (external indicator) on either the emitter or the receiver.

3. Attach the key cap for muting to the emitter/receiver on which the muting lamp (external indicator) was

not installed.

 Muting Sensor

The muting sensor is the sensor that is the trigger for temporarily disabling the F3SJ's safety functions. Through-beam or retro-reflective photoelectric sensors, proximity sensors, or limit switches can be used as muting sensors. (recommendation: OMRON E3Z series, E2E series, D4N series)Use those with PNP outputs or N.O. type contacts.

 Muting Lamp (External Indicator)

Because it notifies workers that the muting function is operational, the muting lamp (external indicator) must be installed. Use the F39-A01P-PAC or an F39-JJ3N universal indicator cable and a commercially available external indicator.

Recommended External Indicators p.56

 Installation Standard for Muting Sensors

•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 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 and muting sensors so that no person is able to accidentally enter the hazardous zone while the muting function is enabled.

 Installation Example 1 of Standard Muting Mode (using 2

muting sensors)

This is an example of 2 retro-reflective type photoelectric sensors used as muting sensors installed in a cross pattern. Use 2 sensors when the length L of the workpieces are not constant or are insufficient.

The override function forcibly turns the safety outputs ON when the muting start condition is not satisfied. If a workpiece stops while passing through the detection zone of the F3SJ, as shown below, causing a muting error, the normal state cannot be recovered unless the workpiece is removed from the muting sensors and the detection zone of the F3SJ. However, the override function will mute the safety outputs of the F3SJ so that the conveyor can be restarted to move the workpiece out of the muting sensors and F3SJ detection zone.

The override function can be enabled for up to 60s. The muting lamp (external indicator) blinks while overriding.

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

Muting lamps (external indicators) that indicate the state of the muting and override functions must be installed where they are clearly visible to workers from all the operating positions.

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 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'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.

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 in environments where flammable or explosive gases are present. Doing so may cause an explosion.

The

F3SJ

cannot protect a person from an object flying from a hazardous zone. Install protective cover(s) or

fence(s).

Make sure that the F3SJ is securely mounted and its cables and connectors are properly connected.

Correct installation

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

Incorrect installation

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

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

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

Safety distance (S)

Courtesy of CMA/Flodyne/Hydradyne ▪ Motion Control ▪ Hydraulic ▪ Pneumatic ▪ Electrical ▪ Mechanical ▪ (800) 426-5480 ▪ www.cmafh.com

 Safety Distance

The safety distance is the distance that must be set between the F3SJ 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 the relevant standards.

Make sure to secure the safety distance (S) between the F3SJ 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 that the response time of the machine has not changed.

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

2002 (European standard EN999) (Reference)

If a person approaches the detection zone of the F3SJ 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

• C: Additional distance calculated by the detection capability

of the F3SJ

Chapter3 Installation Conditions

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

•S = Safety distance (mm)

•Tm = Machine's response time (s)

•Ts = Response time of the F3SJ from ON to OFF (s)

•d = Detection capability of the F3SJ (mm)

If the result If the result exceeds 500mm, use the following expression where K = 1,600mm/s. S=1,600mm/s x (Tm + Ts) + 8 x (d - 14mm) . . . Formula (3)

If the result of this formula (3)

[Calculation example] When Tm = 0.05s, Ts = 0.01s, and d = 20mm: S=2,000mm/s x (0.05s + 0.01s) + 8 x (20mm - 14mm) = 168mm . . . Formula (2)

< 100mm, use S = 100mm.

< 500mm, use S = 500mm.

In case of horizontal approach of a human body to F3SJ's detection zone

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

Hazard

Safety distance (S)

•S = Safety distance (mm)

•Tm = Machine's response time (s)

•Ts = Response time of F3SJ from ON to OFF (s)

Chapter3 Installation Conditions

•H = Installation height (mm)

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

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

[Calculation example] When Tm = 0.05s, Ts = 0.01s, and d = 20mm: S = 1,600mm/s x (0.05s + 0.01s) + 1200 - 0.4 x 500mm = 1096mm

 How to calculate the safety distance specified by American standard ANSI B11.19

(reference)

If a person approaches the detection zone of the F3SJ 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 1,600mm/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)

•Tr = Response time of the F3SJ 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 (unit: mm)

[Calculation example] When K = 1,600mm/s, Ts + Tc = 0.06s, brake monitor setting time = 0.1s, Tr = 0.01s, and d = 20mm: Tbm = 0.1 - 0.06 = 0.04s Dpf = 3.4 x (20 - 7.0) = 44.2mm S = 1,600 x (0.06 + 0.01 + 0.04) + 44.2 = 220.2mm

 Mutual Interference Prevention

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

When using more than 1 set of F3SJ, install them so that mutual interference does not occur, such as by configuring series connections or using physical barriers between adjacent sets.

Chapter3 Installation Conditions

 Series Connection

Series connection can prevent mutual interference when multiple sensors are used. Up to 3 sets, 240 beams, can be connected. The emission of series-connected F3SJ is time-divided, so mutual interference does not occur and safety is ensured.

How to perform series connection p.52

 No Connection

Mutual interference is prevented in up to 3 sets, using interference light avoidance algorithm. If 4 or more sets of F3SJ are installed and are not connected to each other, arrange them so that mutual interference does not occur. If 2 sets are installed near each other, reflection from the surface of the F3SJ may cause mutual interference. When mutual interference occurs, the F3SJ enters lockout. Combining countermeasures 1 to 4 shown below is effective.

1. Install a physical barrier between 2 sets

Replacement method

using F39-LJ5

mounting

For lengths greater than the F3SN-0277P25: Subtract a number, ranging from 7 to 22, from the F3SN's 4-digit number and apply it as the F3SJ's 4digit number, and then replace with the standard brackets included with the product. [Selection example] F3SN-A0322P25 becomes F3SJ-A0300P25-TS (replace with standard brackets)

The formula shown above is recommended for mounting in the center of a mounting hole. If a mounting position is unmatched, another mounting hole must be drilled.

Chapter3 Dimensions

- The protective height becomes shorter by 7 to 22mm.

- Replace with outward-facing mounting of F39-LJ5 when you want to set the detection surface height to be same as the F3SN. However, the F39-LJ5 and intermediate mounting brackets cannot be mounted simultaneously, so set the protective height to 600mm or less.
