F3SG-R

User’s Manual

Introduction

For machines

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 full-rotation clutch. Otherwise, the machine may not stop before a person reaches the hazardous part, resulting in serious injury.

To use F3SG-R in PSDI mode (initiation of cycle operations by a presence sensing device), you must configure an appropriate circuit between F3SG-R and the machine.For details about PSDI, refer to OSHA1910.217, IEC61496-1, and other relevant standards and regulations.

For installation

Make sure Responsible Person tests the operation of the F3SG-R after installation to verify that the F3SG-R operates as intended. Make sure to stop the machine until the test is complete. Unintended installation, wiring or function settings may cause a person to go undetected, resulting in serious injury.

Make sure to install the F3SG-R at the safety distance from the hazardous part of the machine. 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 passing through the sensor's detection zone. If access to the hazardous part by reaching over the detection zone of a vertically mounted F3SG-R cannot be excluded, the height of the detection zone and the safety distance shall be determined in consideration of such a risk. 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 to step into the hazardous zone of a machine and remain behind the F3SG-R's detection zone, configure the system with Restart Interlock function due to unexpected startup. Failure to do so may result in serious injury.

Install the 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.

Install the pre-reset switch always in the hazardous zone and where it cannot be activated from outside the hazardous zone.

The F3SG-R cannot protect a person from a projectile exiting the hazardous zone. Install protective cover(s) or fence(s).

When the fixed blanking or floating blanking function is used, observe the following. Failure to do so may cause a person to go undetected, resulting in serious injury.

• Responsible Person must verify that a test rod is detected for all detection zones except the blanked area.

• When the fixed blanking function is used, install a protective structure to cover the whole blanked area in order to prevent personnel approach to hazardous part of the machine through the blanked area.

F3SG-R

User’s Manual

Detection capability gets larger when fixed/floating blanking or reduced resolution function is used. When these functions are used, the safety distance calculation must be based on the increased detection capability for these functions. Otherwise the machine may not stop before a person reaches to the hazardous part, resulting in serious injury.

A warning zone must not be used for safety applications. Always install your system so that a detection zone should be passed before reaching a hazardous part of the machine. If access to the hazardous part by reaching over the detection zone of a vertically mounted F3SG-R cannot be excluded, the height of the detection zone and the safety distance shall be determined in consideration of such a risk.

When a warning zone is configured, you must attach labels that indicate a border between normal detection zone and warning zone. Otherwise the machine may not stop before a person reaches to the hazardous part, resulting in serious injury.

A warning zone must be configured based on a safety distance.

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

Introduction

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, the machine may not stop operating, resulting in serious injury.

Muting lamps 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 2 independent input devices for muting inputs. Failure to do so may result in a muting status due to a single muting sensor's failure.

You must install F3SG-R, muting sensor, and physical barrier, and configure time settings for muting so that an operator should not enter hazardous zone.

The Dynamic Muting function can configure a new muting zone after muting is enabled based on a result measuring a workpiece height for a certain period of time. The function must be completely verified by a trained and qualified person before being used. Take additional safety measures if necessary.

Install the switch to activate the 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.

Override time must be properly configured for its application by a sufficiently trained and qualified person.

Make sure to connect an override cancel switch to the Reset line when using the override function. Otherwise the override state may not be released by the override cancel switch, resulting in serious injury.

Introduction

Reflector

Position with retro-reflection

Position with detection zone bent at 90

When muting error occurs with workpiece blocking the F3SG-R, there are two methods to forcibly remove the workpiece.

1) Manual operation (with additional safety measure); or

2) Override function (Override at Normal Operation / Override upon Startup)

Only one of the methods, either 1) or 2) must be used. If they are used at the same time, the override may be activated at an unexpected timing.

Install F3SG-R so that it is not affected by reflective surfaces. Failure to do so may hinder detection, resulting in serious injury. For an installation distance from reflective surfaces, see 4-1-

3. Distance from Reflective Surfaces.

When using more than 1 set of F3SG-R in adjacent areas, the emitter of one F3SG-R may interfere with the receiver of the other, causing the safety functions to stop working properly. Install and configure them so that mutual interference does not occur.

Make sure that foreign material such as water, oil, or dust does not enter the F3SG-R or the connector while the cap or the cover of the DIP Switch is removed.

To change the response time, calculate the safety distance based on the setting. Otherwise, the machine may not stop before a person reaches the hazardous part, resulting in serious injury.

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 alter the detection zone to a 90-degree angle.

Perform an inspection for all F3SG-R as described in Chapter 6 Checklists. When using cascade connections, perform inspections for every connected F3SG-R.

For wiring

When using the PNP output, connect the load between the output and 0 V line. When using the NPN output, connect the load between the output and +24 VDC line. Connecting the load between the output and a different power supply line from the above will result in a dangerous condition because the operation mode of safety output is reversed to "Dark-ON".

F3SG-R

User’s Manual

When using the PNP output, do not ground +24 VDC line. When using the NPN output, do not ground 0 V line. Otherwise, a ground fault may turn the safety output ON, resulting in a failure of stopping the machine.

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 F3SG-R to a DC power supply of higher than 24 VDC+20%. Also, do not connect it to an AC power supply. Failure to do so may result in electric shock.

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

Do not use the auxiliary output for safety applications. Failure to do so may result in serious injury when the F3SG-R fails.

For the F3SG-R 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%)

1-6-2. Calculation of Response Time of Cascaded Segments

The F3SG-RA can be used in cascade connection. In case of a cascade connection, a response time is determined by the total number of beams. If the total number of beams of all F3SG-RA in a cascade connection is 140 or less, its response time is 12 ms (Code A)/13 ms (Code B). The number of beams of respective F3SG-RA, however, must be 112 or less. If an F3SG-RA with 113 or more beams is included in the cascade connection, its response time is 17 ms (Code A)/18 ms (Code B).

The F3SG-RE cannot be used in cascade connection.

The diagram below summarizes the relation described above.

2-3. Optical Synchronization

F3SG-RA Series X

F3SG-RE Series X

System Operation and Functions

2-3-1. Overview

Synchronization is required between an emitter and a receiver for normal operation of F3SG-R. F3SG-R uses a specific beam for Synchronization. The beam is hereinafter called synchronization beam.

Depending on sensor configuration, the synchronization beam is either of the followings:

• One segment system: End beams (Top or Bottom beam)

• Cascaded system* : End beams (Top or Bottom beam) of the primary sensor * The F3SG-RE cannot be used in cascade connection.

For an emitter and a receiver to synchronize, at least one synchronization beam must be unblocked.

The synchronization process is performed when: (1) The power is turned on for an emitter and a receiver (2) All beams of the primary sensor are blocked and then unblocked (3) Synchronization is lost due to an error such as noise and ambient light

The sensor can maintain the synchronization in other cases than those described above and it is not necessary to keep the synchronization beam unblocked all the time.



Response time of “OFF (Synchronized) → ON” and “OFF (Not synchronized) → ON”

Lower Lower

Response time of “OFF (Synchronized) → ON” is the response time from when the F3SG-R is in the OFF state and the emitter and receiver are synchronized to when the F3SG-R is turned to the ON state. Response time of “OFF (Not synchronized) → ON” is the response time from when the F3SG-R is in the OFF state and the emitter and receiver are not synchronized to when the F3SG-R is turned to the ON state. This response time is longer since the F3SG-R evaluates if it is blocked or unblocked, after the synchronization is established.

The F3SG-RA turns the safety outputs OFF when its power is turned on or the F3SG-RA is blocked and holds this state until a reset signal is received. This state is called "interlock state". The function to keep the Interlock state is called "Interlock function". The F3SG-RA has two Interlock functions, Start Interlock and Restart Interlock.

Chapter2 Interlock

The F3SG-RE does not have the Interlock state and is only available with Auto Reset mode.

• Start Interlock

The F3SG-RA turns the safety output OFF at power-on or recovery from power failure and keep this state until a reset signal is received. This is useful if you want to keep the machine stopped until a pre-operation check is completed after the power is turned ON.

• Restart Interlock

The F3SG-RA turns the safety output OFF when the F3SG-R is blocked and keep this state until a reset signal is received. Restart interlock is useful if you want to restart the machine being stopped upon interruption of the F3SG-R, only after the operator confirms a safe condition.

The F3SG-RA offers three ways to reset the Interlock state: Auto Reset, Manual Reset, and Pre-Reset applicable to specific applications.

• Auto Reset mode

Auto Reset mode disables the Start Interlock and Restart Interlock. When the interrupting object is removed from the detection zone, the Interlock state is automatically released and the safety outputs are automatically turned ON. Auto Reset is desirable for application where a worker is not able to enter the area between the detection zone and the hazardous part of the machine or you use a relay unit to activate Start Interlock and Restart Interlock.

• Manual Reset mode

Manual Reset mode enables the Start Interlock and Restart Interlock. When a reset signal is given while no interrupting object exists in a detection zone, the safety outputs are turned ON.

• Pre-Reset mode

An operator may enter and work in the hazardous zone for maintenance. Under such a circumstance, another operator may press the resest switch to restart the machine without recognizing the operator working in the hazardous zone, posing a danger. The Pre-Reset

System Operation and Functions

2-12. Muting

F3SG-RA Series X

F3SG-RE Series

Muting function temporarily disables safety function of the F3SG-RA, keeping safety output 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 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 following three operation modes are available for the muting function.

1.Standard Muting Mode (factory default setting)

2.Exit-Only Muting Mode

3.Position Detection Muting Mode

Refer to 2-1. Combination of Functions for more information on the use in conjunction with other functions.

Chapter2 Muting

The following settings are available for a beam range to be the muting state.

• All Range Disabled Setting

• Partially Disabled Setting

• Dynamic Muting Setting

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 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.

User’s Manual

Chapter2 Muting

System Operation and Functions

All muting lamps that indicate state of muting function must be installed where workers can see them from all the operating positions.

Use 2 independent input devices for muting input. A muting state may occur due to a single failure of the muting sensor.

You must install F3SG-RA, muting sensor, and physical barrier, and configure time settings for muting so that an operator should not enter hazardous zone.

The Dynamic Muting function can configure a new muting zone after muting is enabled based on a result of workpiece height measurement for a certain period of time. The function must be used after careful verification by a qualified person with sufficient training. Apply additional safety measures if required.

 Using muting function

<Muting sensor> The muting sensor is the sensor to trigger a signal to temporarily disable the safety functions of the F3SG-R. You can use a photoelectric switch of through-beam type or reflective type proximity switch, or limit switch. (Recommended: OMRON E3Z series, E2E series (3-wire type), D4N series) Use a 3-wire type transistor output, which is the same as the output type of the F3SG-RA, or N.O. type contact. Two-wire type sensor must not be used.

When the F3SG-RA is in PNP settings, use the muting sensor of the PNP transistor type. When the F3SG-RA is in NPN settings, use the muting sensor of the NPN transistor type.

<Muting lamp> You may need a muting lamp depending on your application or as a result of a risk assessment analysis. Before determining the use of the muting lamp, check laws and regulations of the country or region where the F3SG-RA is used and make sure of full compliance with them. For the muting lamp, use a Lamp (F39-LP and F39-BTLP, sold separately) or a commercially available external indicator. The external indicator can be connected to the auxiliary output.

For settings of the auxiliary output, see 2-11. Auxiliary Output.

For settings of the optional Lamp (F39-LP and F39-BTLP, sold separately), see 2-21. Lamp

Top-beam-state indicator Blinks during muting/override. Bottom-beam-state indicator Sequence error indicator Blinks during a muting sequence error. Configuration indicator If the Dynamic Muting function is enabled, the indicator flashes while measuring

the workpiece height. If the Dynamic Muting function is enabled, the indicator turns on after the new

muting zone is reflected.

Muting Range Description

Full Zone Muted State (factory default setting)

Partial Zone Muted State

Dynamic Muting This can be used by enabling the Dynamic Muting function.

Full area of the detection zone is muted. This disables the full detection zone and is used typically.

A specified area in the detection zone configured by the Configuration Tool is muted. This can be used if you want to disable only a specific area of the detection zone. Specifying the full zone results in the Full Zone Setting State.

The full detection zone is disabled for a certain time period from the start of the muting, then a partial zone is muted depending on the detected workpiece size.

2-12-4. Dynamic Muting

2-12-1. Standard Muting Mode

The factory default setting is set to this mode. Turning muting inputs A and B ON with time difference enables muting state.

Chapter2 Muting

 Start Conditions

If both of the following two conditions are satisfied, the muting state is enalbed.

1. No interrupting object is found in the F3SG-RA's detection zone, and safety outputs are ON.

2. After muting input A is turned ON*, muting input B is turned ON* within the range between the

muting input time limit values T1min (0.1 s) and T1max (4 s).

*PNP setting: Vs-3V to Vs, NPN setting: 0 to 3V

Muting state can be enabled in up to 80ms after the condition No.2 is satisfied. When the condition No.1 is satisfied but the time requirement of the condition No.2 is not, a muting sequence error occurs and the Sequence error indicator on the receiver blinks. However, when there is a muting sequence error, the F3SG-RA does not enter the Muting state but it continues the normal operation with the safety function enabled.

For muting error indication, see 7-1-2-3. Muting Sequence Error Indication.

Muting error can be released by any of following conditions:

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

2. Power cycle when muting inputs A and B are in the OFF state.

* The correct initial muting condition is the state where the following two conditions are satisfied.

• Safety outputs of the F3SG-RA are turned ON.

• Muting input A and B are turned OFF.

 End conditions

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

• Muting input A or B turns OFF for the maximum allowable muting signal interruption of T3 (at least

0.1 s: configurable) or longer.

• The duration of the muting state exceeds the muting time limit of T2 (at least 60 s: configurable).

Muting state is also released when the F3SG-RA enters the Lockout state.

<Reference: Preventing light interference of muting sensor> When a photoelectric sensor is used as a muting sensor, light interference may cause a muting error of F3SG-RA. The cause and measures for light interference are shown as follows:

(1) Interference between muting sensors

• Use sensors with mutual interference prevention (such as retro-reflective E3Z-R series)

• Use laser-type sensors (such as laser-type E3Z-LR series)

• Take distance from a sensor causing the interference

• Displace beams for each other to prevent interference (change installation height or place them

crosswise)

• Install a physical barrier

• Attach interference prevention filter (provided for E3Z series as accessories)

• Attach a slit to reduce light intensity (provided for E3Z series as accessories)

• Lower the sensitivity

• Reduce a distance between a workpiece and a muting sensor to prevent reflected light from a workpiece

F3SG-R

5. The workpiece passed F3SG-RA’s detection zone

A workpiece has passed F3SG-RA’s detection zone. When the muting end wait time: T4 (1 s: configurable) passes after the F3SG-RA is unblocked, the muting state is released.

 Installation Distance

Distances between muting sensors A1, B1, and F3SG-RA must be configured based on speed of a workpiece. Distance d1 between muting sensors A1 and B1 must satisfy Equations (1) and (2). Distance d2 between muting sensor A1 and F3SG-RA must satisfy Equations (3) and (4). Time t1 [ s ] to turn muting sensors A1 and B1 in this order is:

t1 = d1 / V . . . . . . . . . . . Equation (1) d1 [ m ] : Distance between muting sensors A1 and B1

V [ m/s ] : Approach speed of a workpiece

Chapter2 Muting

Time t1 in Equation (1) for F3SG-RA to enter muting state is within a range shown below:

T1min < t1 < T1max. . . . Equation (2) T1min [ s ] : Muting input time limit value (minimum)

T1max [ s ] : Muting input time limit value (maximum)

The values of T1min and T1max can be changed by the Configuration Tool.

Time t2 [ s ] for a workpiece to pass F3SG-RA’s detection zone after passing the muting sensor A1 is:

t2 = d2 / V . . . . . . . . . . . . Equation (3) d2 [ m ] : Distance between muting sensor A1 and F3SG-RA

V [ m/s ] : Approach speed of a workpiece

Time t2 in Equation (3) must satisfy following condition:

t2 < T5 . . . . . . . . . . . . . . Equation (4) T5: Exit-only muting delay time

The value of T5 can be changed by the Configuration Tool.

Sensors must be installed so that person’s passing should not cause muting state.

2-12-3. Position Detection Muting Mode

Muting state is enabled when muting input A turns ON from the OFF state and muting input B turns OFF from the ON state within the muting input time limit value T1max, measured by a limit switch, etc. Muting inputs must be heterogeneous redundant inputs such as the combination of N.O. contact and N.C. contact types. (When using photoelectric sensors of PNP output, use one for Light-ON operation while the other for Dark-ON.) This mode can be used for such a case that the F3SG-RA should be temporarily disabled while a worker puts objects at a loading station.

 Start conditions

If both of the following 2 conditions are satisfied, the muting state is enalbed.

1. No interrupting object is found in the F3SG-RA's detection zone, and the safety outputs are ON.

2. The duration between when the muting input A is turned ON* from the OFF state and when the muting input B is turned OFF from the ON state* is within the range between the muting input time limit values T1min (0.1 s) and T1max (4 s). Order of muting inputs A and B is irrelevant.

*PNP setting: Vs-3V to Vs, NPN setting: 0 to 3V

Chapter2 Muting

Muting state can be enabled in up to 80 ms after the condition No. 2 is satisfied. If the condition No. 1 is satisfied but the time requirement of the condition No.2 is not, a muting error occurs, and the Sequence error indicator on the receiver turns ON. However, when there is a muting error, the F3SG-RA continues the normal operation with the safety function enabled.

For muting error indication, see 7-1-2-3. Muting Sequence Error Indication.

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 when the muting inputs A and B are in the OFF state.

*1 The correct initial muting condition is the state where the following two conditions are satisfied.

• Safety outputs of the F3SG-RA are turned ON.

• Muting input A is turned OFF and Muting input B is turned ON.

 End conditions

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

• Muting input A is in the OFF state for T3 or longer (0.1 s or longer).

• Muting input B is in the ON state for T3 or longer (0.1 s or longer).

• The duration of the muting state exceeds the muting time limit of T2 (60 s).

Muting state is also released when the F3SG-RA enters the Lockout state.

 Zone Measurement Start Condition

After the muting start condition is satisfied and the full detection zone is muted, interruption of a part of the F3SG-RA causes the Zone Measurement to start.

 Zone Measurement

The Zone Measurement monitors the highest and lowest parts of a passing workpiece during the dynamic muting measurement time Tdyn (3 s). (Void spaces in workpiece(s) are ignored.)

 Zone Determination

A zone enclosed by the highest and the lowest parts of the workpiece is set as a new muting zone. Configuring a dynamic muting allowable beam allows the muting zone to be expanded by the number of allowable beams. Configuring a dynamic muting allowable beam prevents unintended line stop due to swing of a workpiece, etc. (The factory default setting of the dynamic muting allowable beam is 1.)

F3SG-RA Series X

F3SG-RE Series

Chapter2 Override

The override function turns the safety outputs ON when the muting start condition is not satisfied. If a workpiece stops while passing through the F3SG-RA, 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 field of the F3SG-RA. However, the override function will mute the safety outputs of the F3SG-RA so that the conveyor only can be restarted to move the workpiece out of the muting sensors and detection zone.
