Press MODE key to light up
MODE indicator / ADJ (yellow).
1
In case the threshold value is to be increased
(sensitivity to be reduced), turn the jog
switch to the ‘ ’ side to increase the
threshold value slowly.
If the jog switch is turned continuously
to the ‘ ’ side, the threshold value
2 increases rapidly.		or
In case the threshold value is to be
decreased	(sensitivity to	be
increased), turn the jog switch to the
‘ ’ side to decrease the threshold
value slowly. If the jog switch is turned continuously to
the ‘’ side, the threshold value decreases rapidly.

When jog switch is pressed, the threshold value is confirmed.

Timer operation setting

•The setting for whether the timer is used or not can be done when MODE indicator / TIMER (yellow) lights up.

•10 ms OFF-delay (initial value) timer is automatically set when the timer is set to be used.

•Further, an OFF-delay (initial value) which is useful when the response of the connected device is slow, etc., an ON- delay which is useful to detect only objects taking a long time to travel, and ONE SHOT, which is useful when the input specifications of the connected device require a signal of a fixed width, are possible with the FX-301series. Refer to the ‘Fiber Sensor Guide Book’ or ‘SUNX fiber sensor home page’ (http://www fiber-sensor.com) for the setting method of the OFF-delay, ON-delay and ONE SHOT timer intervals.

Key-lock function

•With the FX-301B(P)/G(P)/H(P), if jog switch and MODE key are pressed for more than 3 sec. at the same time in ‘RUN’ mode condition, the key operations are locked, and only the threshold value confirmation function or the adjust function (valid only when the adjust lock function is canceled) is valid.

To cancel the lock function, press both the keys for more than 3 sec. once again.

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 sensor may get burnt or damaged.

•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.

•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.

•Take care that short-circuit or wrong wiring of the load may burn or damage the sensor.

•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.

•Ensure that an isolation transformer is utilized for the DC power supply. If an auto transformer is utilized, the main amplifier or power supply may be damaged.

•Make sure to use the optional quick-connection cable for the connection of the amplifier. Extension up to total 100 m 328.084 ft is possible with 0.3 mm2, or more, cable. However, in order to reduce noise, make the wiring as short as possible.

Others

•Do not use during the initial transient time (0.5 sec. approx.) after the power supply is switched on.

•Take care that the sensor is not directly exposed to fluorescent light from a rapid-starter lamp or a high frequency lighting device, as it may affect the sensing performance.

•This sensor is suitable for indoor use only.

•Avoid dust, dirt, and steam.

•Take care that the product does not come in direct contact with water, oil, grease, or organic solvents, such as, thinner, etc.

•This sensor cannot be used in an environment containing inflammable or explosive gasses.

•Never disassemble or modify the sensor.

(Note)

Note: The OFF-delay timer interval set in the PRO mode is displayed.
