CHAPTER 3 FUNCTIONS

3-1 Functional Descriptions <When Using with Light Curtain SF4B Series Only>

This section describes each function.

When using with SF-C14EX, refer to ‘3-2 Functional Descriptions <When Using in Combination
with Application Expansion Unit SF-C14EX>’.

If configuration of the system is changed (change of the SF-C14EX to be used / not to be used,
replace the sensor etc.), set the function setting again.



3-1-1 Fixed Blanking Function

This is a function that the control output (OSSD 1, OSSD 2) of SF4B series is not turned off, even if the
specified beam channel(s) is blocked off.
This is useful when an obstacle always blocks off the specific beam channel(s).

There are ‘CLR’, ‘AUTO’ and ‘MANUAL’ for the setting method.

࡮ CLR setting : The fixed blanking function is to be invalid (Factory setting).
࡮AUTO setting : The currently blocked off beam channels are set as ‘effective beam channels’ in the

fixed blanking function. Be sure to set this function in the state where the emitter emits
light. Furthermore, this function cannot be set in the state where all beam channels
receive lights / are blocked.

࡮ Manual setting : Each beam channel can be set to ‘effective / ineffective’ in the fixed blanking function

respectively.

When the fixed blanking function is used, the control output (OSSD 1, OSSD 2) of SF4B series
is not turned off even if the particular beam channels are blocked. By using a protection
structure etc., make the hazardous area of the press machine inaccessible to personnel
through the sensing area of the particular beam channels.

When the effective beam channel(s) in the fixed blanking function receive(s) the beam(s) from
the emitter, the control output (OSSD 1, OSSD 2) of the SF4B series is fixed to ‘OFF’. In this
case, check the mounting condition and turn the power on again.
(Even if the power is turned on again, the fixed blanking function still stays effective.)
When the fixed blanking function is used, the received light intensity indicator of SF4B series
is turned off regardless of the received light intensity.

3-1-2 Floating Blanking Function

s

This function is set in each sensor.
If the number of the blocked beam channels is less than the set number of the beam channels, the control
output (OSSD 1, OSSD 2) of SF4B series is not turned ‘OFF’.
This function is useful when an obstacle moves within the detecting area.
The factory setting of this function is ‘ineffective’.

The following items can be set.

Set number of beam channels

࡮Selectable among 0 (the floating blanking function is ineffective), 1, 2 or 3.

Ineffective setting of both end beam channel

࡮‘Effective’ / ‘Ineffective’ of the floating blanking function for the both ends the beam channels can be selected.

࡮SET (Effective) : The floating blanking function becomes ineffective for the both end beam channels.

In case either end of the beam channel is blocked, the control output (OSSD 1, OSSD 2)
of SF4B series is turned ‘OFF’ regardless of the set number of the beam channels.

࡮CLR (Ineffective) : The floating blanking function becomes effective for all beam channels including

both ends beam channels.

Non-serial beam channel setting

࡮SET (Effective) : Even if the beam channels are blocked discontinuously in the set beam channels,

the control output (OSSD 1, OSSD 2) of SF4B series is turned ‘ON’.
(Discontinuous mode)

࡮CLR (Ineffective) : When the beam channels are blocked discontinuously even in the set beam channels,

the control output (OSSD 1, OSSD 2) of SF4B series is turned ‘OFF’.
(Continuous mode)

࡮When using the floating blanking function, the size of the minimum sensing object become

larger, and the safety distance is longer as well. For the calculation of the safety distance,
refer to the instruction manual enclosed with SF4B series.

࡮Before designing the system, refer to the relevant laws and standards of the region where

SF4B series is to be used and then install SF4B series and this device.

3-2 Functional Descriptions <When Using in Combination with Application Expansion Unit

k

SF-C14EX>

This section describes each function.

If configuration of the system is changed (replacement of the SF-C14EX, series connection,
change the number of the beam channels etc.), set the function setting again. When using in
combination with the SF-C14EX, a part of the SF4B functions is changed as well.

3-2-1 Fixed Blanking Function

This is a function that the safety output 1 and 2 of SF-C14EX are not turned off, even if the specified beam
channel(s) is blocked off.
This is useful when an obstacle always blocks off the specific beam channel(s).

There are ‘CLR’, ‘AUTO’ and ‘MANUAL’ for the setting method.

࡮ CLR setting : The fixed blanking function is to be invalid (Factory setting).
࡮AUTO setting : The currently blocked off beam channels are set as ‘effective beam channels’ in the

fixed blanking function. Be sure to set this function in the state where the emitter emits
light. Furthermore, this function cannot be set in the state where all beam channels
receive lights / are blocked.

࡮ Manual setting : Each beam channel can be set to ‘effective / ineffective’ in the fixed blanking function

respectively.

When the fixed blanking function is used, the safety output 1 and 2 of SF-C14EX are not turned
off even if the particular beam channels of SF4B series are blocked. By using a protection
structure etc., make the hazardous area of the press machine inaccessible to personnel
through the sensing area of the particular beam channels of SF4B series.

When the effective beam channel(s) in the fixed blanking function receive(s) the beam(s) from
the emitter, the safety output 1 and 2 of the SF-C14EX are fixed to ‘OFF’. In this case, chec
the mounting condition and turn the power on again.
(Even if the power is turned on again, the fixed blanking function still stays effective.)
When the fixed blanking function is used, the received light intensity indicator of SF4B series
is turned off regardless of the received light intensity.

3-2-2 Floating Blanking Function

s

g

This function is set in each sensor.
If the number of the blocked beam channels is less than the set number of the beam channels, the safety
output 1 and 2 of SF-C14EX are not turned ‘OFF’.
This function is useful when an obstacle moves within the detecting area of SF4B series.
The factory setting of this function is ‘ineffective’.
The following items can be set.

Set number of beam channels

࡮Selectable among 0 (the floating blanking function is ineffective), 1, 2 or 3.

Ineffective setting of both end beam channel

࡮‘Effective’ / ‘Ineffective’ of the floating blanking function for the both ends the beam channels can be

selected.

࡮SET (Effective) : The floating blanking function becomes ineffective for the both end beam channels.

If either end of the beam channel is blocked, the safety output 1 and 2 of

SF-C14EX are turned ‘OFF’ regardless of the set number of the beam channels.

࡮CLR (Ineffective) : The floating blanking function becomes effective for all beam channels including

both ends beam channels.

Non-serial beam channel setting

࡮SET (Effective) : Even if the beam channels are blocked discontinuously in the set beam channels,

the safety output 1 and 2 of SF-C14EX are turned ‘ON’. (Discontinuous mode)

࡮CLR (Ineffective) : When the beam channels are blocked discontinuously even in the set beam channels,

the safety output 1 and 2 of SF-C14EX are turned ‘OFF’. (Continuous mode)

࡮When using the floating blanking function, the size of the minimum sensing object become

larger, and the safety distance is longer as well. For the calculation of the safety distance,
refer to the instruction manual enclosed with SF4B series.

࡮Before designing the system, refer to the relevant laws and standards of the region where

SF4B series is to be used and then install SF4B series and this device.

࡮The minimum sensing object differs depending on the set number of the beam channels.

3-2-3 Auxiliary Output Switching Function

This function changes the operation state of the auxiliary output (AUX4) of SF-C14EX. It is useful when
desired to make an indicator to operate or inform the operation state of the sensor to PLC.

Since the auxiliary output is non-safety output, do not use the auxiliary output for halting the
device.

When the fixed blanking function is used, if an obstacle exists in the set area and other area is in light receiving condition,
the safety output 1, 2 are in ON sate, however, the auxiliary output becomes OFF since the sensor has been detecting
the obstacle.

3) The state of the auxiliary output remains the same even if the SF4B series state changes.

4) When using in combination with SF-C14EX, the muting function cannot be set on SF4B side. Thus, the state of the

auxiliary output remains the same regardless of the SF4B series state.
