Connecting Fiber Unit

1 Open the dust cover in the

direction shown by arrow 1.

Move down the fiber lock lever in the direction shown by arrow 2.

Insert a fiber unit into the fiber insertion holes to a length of the fiber insertion sign (i.e., approximately 14 mm).

Move down the fiber lock lever in the direction shown by arrow 4.

Note

If a thin fiber unit is used, an adapter provided with the thin fiber unit will be required. Unless the right adapter is connected, the th in fiber unit will not detect targets correctly. (The adapter is supplied with the fiber unit.)

• To connect the coaxial reflective type fiber unit to the amplifier, connect the single-core fiber to the transmitter side, and connect the multiple-core fiber to the receiver side.

External Input

Signals can be input externally by selecting an external input function (page 5, No. 5).

The signal can be accepted by short-circuiting the pink wire for 2 ms or more as shown below for each model (20 ms for OFF).

* FS-V33/V33P only. * Setting using an external input is up to 1 million times. * No inputs are accepted while setting each mode.

When external calibration is selected, the operation is the same as with the SET button.

 Special Function

By performing the following operation, both sensitivity setting and scaling can be performed using external input.Select external calibration (page 5, No. 5) and display scaling (page 6, No. 7).The following is the example when using the % calibration.

Making Sensitivity Settings

 Two-point Calibration

In this mode, the setting value used will be the mean value of two sensing values obtained with and without a workpiece.

Press the SET button without any workpiece placed in front of the fiber unit.

Place a workpiece placed in front of the fiber unit, and press the SET button.

If the sensitivity difference does not have enough room, “



” flashes for about two seconds

after the calibration is complete. The set value is stored in memory even in that case.

 Maximum Sensitivity Setting

Set the sensitivity without a workpiece in the case of the reflective model, and with a workpiece in the case of the through-beam or retro-reflective model.

Press the SET button for three seconds in the state as shown in the above figure. (Release the button when SET flashes.) The setting value is set slightly higher than the received light intensity at the time of setting the sensitivity.

 Full Auto Calibration

In this mode, the setting value will be set to the mean value of the maximum and minimum incident values obtained within a certain period. Use this mode to detect moving workpieces.

1 Press the set button for a minimum of three seconds while the target

workpiece is passing the sensing area of the fiber unit.

• While the set button is pressed, the sensitivity of the sensor will be set according to the incident values.

• After the setting is completed, the setting value is displayed on the digital monitor.

 Positioning Calibration

Press the SET button without any workpiece placed in front of the fiber unit.

2 Place a workpiece on the position where you want to perform positioning.

Press the SET button for 3 seconds or longer until the display flashes.

Fine-adjusting Sensitivity

The setting value can be directly changed by pressing the manual button.

Percentage Calibration

This is a calibration method that can set the setting value by percentage with reference to the received light intensity at the time of sensitivity setting. For example, if the target value is set to -10P, the setting value is determined 10% lower than the received light intensity when the SET button is pressed.

1 When selecting the sensitivity setting method (page 5, No. 2), select the %

calibration, and set the target value of calibration.

2 Taking the desired light intensity as a reference (normally without a

workpiece), press the SET button.

While the % calibration is in use, other calibrations (sensitivity setting) cannot be used.

Output Selection

Either light-ON mode or dark-ON mode is selectable.

Dynamic Sensitivity Correction (DSC) Function

DSC automatically corrects the setting value according to the changes in the received light intensity when there is no workpiece (output OFF). This function is effective when the light intensity difference is small when judging whether or not there is a workpiece. At Detection mode selection (page 5, No.4), select “Dynamic sensitivity correction mode” beforehand.* How to set the sensitivity is the same as in the normal mode.

The DSC indicator illuminates when the DSC function is set.

* When Light ON is selected, the upper limit of the correctable range is twice as

much as the initial setting value. * The value is stored in memory even after the power is turned off. * The DSC indicator flashes when the light intensity during output OFF greatly

fluctuates or the L/D ON selection is inappropriate. In such a case, check the

setting again.

Edge Detection Mode

This mode detects the change in the received light intensity during a given period of time. (Set at page 5, No. 4)

 Filter Setting

Basically, leave this setting as its initial value. If the passage interval of workpieces is too short for the unit to respond, strengthen the level and try again. The selectable filter level differs depending on the power modes.

*HSP: HIGH SPEED As the number becomes smaller, the filter becomes stronger, which makes the unit difficult to respond to gradual changes in light intensity.

 Making Sensitivity Settings

The sensitivity is set to maximum when the SET button is pressed quickly once. When the setting value is too low and the unit detects objects other than the workpiece, fine-adjust the setting value to a higher number.

 Operation When Switching Outputs

Area Detection Mode

This mode is suited to detecting the received light intensity only of a certain range. To set this mode, select the area detection mode at Detection mode selection (page 5, No.4).

Set the value so that the upper limit setting value is larger than the lower limit setting value. The unit does not respond when the upper limit setting value is less than or equal to the lower limit setting value.

 How to Switch the Upper Limit Setting Value (HI) and the Lower

Limit Setting Value (LO)

When the button is pressed, HI or LO and the setting value alternately flash. When the MODE button is pressed while the display alternately flashes, the HI or LO display changes. How to configure the sensitivity setting is the same as when in the normal detection mode.

Setting the Display Scaling

This is the function to adjust the current received light intensity to the ìscaling target value.

1 When selecting a display value correction function (page 6, No. 7), select the

display scaling function, and set the target value. (The explanation here deals with the case where the target value is set to 2000.)

During the normal display, press the SET button while pressing the MODE button.

(Scaling is performed for the current light intensity at this time.)

The display changes as follows, and the target value (which is 2000) to be set as a scale is displayed.

The scaled value is displayed.

The reference light intensity can be set in the following range in reference with the currently received light intensity:

• No value can be set when the Edge detection mode is selected.

• The value is stored in memory even after the power is turned off.

• External input can be used when using FS-V33(P)/34(P) (page 5, No.5).

Zero-shift Function

The Zero-shift function is used to forcibly set the current light intensity to zero.

At Display value correction function selection (page 6, No.7), select “Zero-shift function”.

2 When the SET button is pressed while the MODE button is pressed, the current

light intensity is forcibly set to zero.

• This function cannot be used when the Dynamic sensitivity correction (DSC) or Edge detection mode is selected.

• The value is stored in memory even after the power is turned off.

• External input can be used when using FS-V33(P)/34(P) (page 5, No.5).

Specifications

*1 When several units are connected, the operating ambient temperature varies depending

on the number of units to be connected. When connecting several units, be sure to mount the units on the DIN rail (mounted on a metal plate), and keep the output current within 20 mA. When 1 to 2 units are connected: -10 to +55 °C, When 3 to 10 units are connected: -10 to + 50 °C, When 11 to 16 units are connected: -10 t o +45 °C When using the 2-output type, count one unit as two units.

*2 When double is set, the respo nse time is twice longer. When using the 2-output t ype, be

careful with the number of units to be connected.

When using the HIGH SPEED mode, the power consumption increases by 160 mW (7 mA).

Error Displays and Corrective Actions

Hints On Correct Use

• Do not wire the amplifier line along with power lines or high-tension lines, otherwise the sensor may malfunction or receive damage due to noise.

• When using a commercially available switching regulator, ground the frame ground terminal and ground terminal.

• Do not use the FS series outdoors, or in a place where extraneous light can enter the light-receiving surface directly.

• Due to the individual dispersion of characteristics and the difference in fiber unit model, the maximum sensing distance or displayed value of all the units are not the same.

•I

f the sensor is used in S-APC mode for a long time, the LED indicators will be imposed with a heavy load. In that case, the sensor will be automatically set to ACC mode where the current consumption of the sensor for light emission will be constant, and “END APC” will be displayed. The sensor can be continuously used in this case. Replace the sensor, however, if highly precise detection is required.
