Part description

Wiring

• Make sure that the power supply is off while wiring.
• Verify that the supply voltage variation is within the rating.
• Take care that if a voltage exceeding the rated range is applied, or if an AC power supply is directly connected, the product may get burnt or damaged.
• In case noise generating equipment (switching regulator, inverter motor, etc.) is used in the vicinity of this product, connect the frame ground (F.G.) terminal of the equipment to an actual ground.
• If power is supplied from a commercial switching regulator, ensure that the frame ground (F.G.) terminal of the power supply is connected to an actual ground.
• Take care that short circuit of the load wrong wiring may burn or damage the product.
• Do not run the wires together with high-voltage lines or power lines or put them in the same raceway. This can cause malfunction due to induction.
• Extension up to total 100 m 328.084 ft (if 5 to 8 units are connected in cascade: 50 m 164.042 ft, if 9 to 16 units are connected in cascade: 20 m 65.617 ft) is possible with 0.3 mm², or more, cable. However, in order to reduce noise, make the wiring as short as possible.
• Take care that cable extension increases the residual voltage.

Mounting

・

Make sure that the power supply is off while connecting / disconnecting the amplifiers and the quick-connection cables.

How to mount the amplifier

①Fit the rear part of the mounting section of the amplifier on a width DIN rail.

②Press down the rear part of the mounting section of the unit on the width DIN rail and fit the front part of the mounting section to the DIN rail.

How to remove the amplifier

①Push the amplifier forward.

②Lift up the front part of the amplifier to remove it.

Note:Take care that if the front part is lifted without pushing the amplifier forward, the hook on the rear portion of the mounting section is likely to break.

Fiber installation

・Insert the fiber into the amplifier after attaching the attachment. Refer to the "Instruction Manual" included with the fiber for details.

①Push the fiber lock lever down.

②Slowly insert the fiber into the insertion slot until it stops. (Note 1)

③Push the fiber lock lever back up until it stops.

Notes:

1)Note that if the fiber is not fully inserted, the sensing distance will decrease. Also note that the bending-resistant fiber may bend during insertion.

2)In case of coaxial reflective type fibers, mount the central fiber (single-core) to the emitter part and the peripheral fiber (multi-core) to the receiver. Note that sensing precision will deteriorate when done in reverse.

・Make sure that the power supply is off while adding or removing the amplifiers.

・Make sure to check the allowable ambient temperature, as it depends on the number of amplifiers connected in cascade.

・In case two, or more, amplifiers are connected in cascade, make sure to mount them on a DIN rail.

・When the amplifiers move on the DIN rail depending on the attaching condition or the amplifiers are mounted close to each other in cascade, fit them between the optional end plates (MS-DIN-E) mounted at the two ends.

・Up to maximum 15 amplifiers can be added (total 16 amplifiers connected in cascade.)

・When connecting more than two amplifiers in cascade, use the sub cable (CN-71-C□) as the quickconnection cable for the second amplifier onwards.

・When connecting amplifiers not close to each other in parallel, be sure to mount the optional end plate (MS-DIN-E) at both sides of each amplifier or affix the communication window seal of the optional fiber amplifier protection seal (FX-MB1) to the communication windows. For details, refer to the instruction manual enclosed with the FX-MB1.

・When the different LED (red / blue / green) types are connected in cascade, mount the identical models together.

・When this product is used with the other digital fiber amplifiers, be sure to place this product to the left most position (When you look from the connector side). If this product is not placed to the leftmost position, this product may not operate properly.

Cascading method

①Mount the amplifiers, one by one, on the DIN rail.

②Slide the amplifiers next to each other, and connect the quick-connection cables.

③Mount the optional end plates (MS-DIN-E) at both the ends to hold the amplifiers between their flat sides.

④ighten the screws to fix the end plates.

Dismantling

①Loosen the screws of the end plates.

②Remove the end plates.

③Slide the amplifiers and remove them one by one.

Switching output operation

When set to Dark-ON (D-ON)

• The operation selection switch can be used to display different output operations (L-ON / D-ON) on the digital display.

When set to Light-ON (L-ON)

Threshold value (sensitivity) adjustment

①Check the incident light intensity [in the digital display (red)] when a sensing object is placed in the sensing position.

②Check the incident light intensity [in the digital display (red)] when the sensing object is removed from the sensing position.

③Turn the threshold value adjuster to the threshold value [in the digital display (green)] that is the value in between ① and ②. (The threshold value is automatically written to the EEPROM.)

Threshold value setting method

• When the threshold value adjuster is turned clockwise, the threshold value increases. When the threshold value adjuster is turned counterclockwise, the threshold value decreases.

・If there is a sufficient level of margin in the incident light intensity, the stability indicator (green) will light up.

Mode selection

• When the setting switch is pressed and held for 2 sec. or more, “SET” mode (mode setting screen) is activated.
• If the setting switch is pressed while in “SET” mode, the mode will change.
• If the threshold value adjuster is turned while a mode is active, the setting item will change and blink.
• When the setting switch is pressed at the item you would like to set, it blinks 3 times and then the setting is confirmed and the mode switches to the next mode.
• If the setting switch is pressed and held for 2 sec. or more or do not press any key for 15 sec. while “SET” mode is active, the mode will switch automatically to “RUN” mode.

Mode table

Mode	Factory setting	Description
Response time change mode		The response time can be set.
Light-emitting amount selection mode (Note 1)		The light-emitting amount can be switched among four levels.
Timer setting mode		Timer settings can be selected; Without timer / OFF-delay timer / ON-delay timer / ONE SHOT timer. Also the timer period can be set.
Digital display inversion mode		The display on the digital display can be inverted.
Eco mode (Note 2)		If no key is pressed for 20 sec. approx. while in “RUN” mode, the digital display turns off automatically. Press the setting switch or move the operation mode switch to make the display light up again. The digital display will light up when the threshold value adjuster is turned, but note that this will also cause the threshold value to change.
Peak / Bottom hold mode		If the setting switch is pressed while “RUN” mode is active, the display will alternate between the peak hold value and the bottom hold value. (The display will refresh every 2 sec.) The display will return to normal if any operation other than threshold value setting is carried out.

Notes:

1)This mode is not incorporated in the blue LED type and green LED type.

2)While the peak / bottom hold mode is ON, the digital display is not turned off even if the Eco mode is set to ON.

Key lock function

Note:Although the display changes to the indication of ‘SET’ condition 2 sec. after pressing the setting switch, keep pressing the switch. Furthermore, the sensor does not go into the key lock setting from ‘SET’ condition.

	The load has short-circuited and excess current is flowing.	Turn off the power, then check the load.
	Communication error has occurred at time of connection.	Check if the mounted amplifiers are in close contact with each other.

Others

• This product has been developed / produced for industrial use only.
• Do not use during the initial transient time (0.5 sec.) after the power supply is switched on.
• This sensor is suitable for indoor use only.
• Do not use this sensor in places having excessive vapor, dust, etc., or where it may come in contact with corrosive gas.
• Take care that the sensor does not come in direct contact with oil, grease, organic solvents, such as, thinner etc., or strong acid, and alkaline.
• This sensor cannot be used in an environment containing inflammable or explosive gases.
• Never disassemble or modify the sensor.
• The changes to the settings are written to the EEPROM, but because the EEPROM has a limited service life, you should avoid changing the settings any more than 1 million times.
