9. Key Lock
The key lock function disables the operation of all keys.
Indicates that the
keys are locked.
Press the manual button for
three seconds while pressing
the mode button.
• Take the same step to unlock the keys.
10. Mode Settings before Shipping (Initialization)
The following factory settings are made before shipping.
EASY
FINE
OFF
Light-ON
Access mode
Power mode
Timer function

* Returning to factory settings: Press the button for a minimum of
five seconds while pressing the button.
11. Hints On Correct Use
• To extend the cable length, use a cable with at least a 0.3 mm 2 cross-
section area. Limit the length of cable extension to no more than 100 m.
(To connect several units, contact Keyence for further information.)
• Do not wire the amplifier line along with power lines or high-tension lines,
or 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.
• If 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 auto-
matically set to ACC mode where the current consumption of the sen-
sor 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.
