EXPLANATION OF FUNCTIONS

Sleep function (Incorporated in all models)
When the sleep input is made Low, the sensor goes into the sleep state
and the operation can be stopped.
Power consumption during the sleep state is 0.3W max. (Without auxili-
ary sensors).
Notes: 1)
2)
3)
Response time of the sleep input is 50ms.
Reactivation from the sleep state to the operation state takes 0.7 sec. approx. Operation
during this transient state should be avoided.
When the sleep function is not used, keep the sleep input wire open or insulated and pre-
vent contact with other wires.
٨
Auxiliary area switching function
(Incorporated in PX-24, PX-24ES, PX-23ES and PX-26 only)
When the auxiliary sensors (
PX-SB1
) are connected to the main sensor,
the auxiliary area can be made effective or ineffective with an external
input. For details refer to the instruction manual enclosed with auxiliary
sensor (
PX-SB1
).
Note: When the auxiliary area switching function is not used, keep the auxiliary area switching input
wire open or insulated and prevent contact with other wires.
Notes: 1)
2)
3)
The sensitivity of the auxiliary sensor is not changed by this function.
The sensitivity cannot be adjusted beyond the range set by the manual adjuster.
When the external sensitivity adjustment function is not used, keep the external sensitivity
adjustment input wire open or insulated and prevent contact with other wires.
٨
External sensitivity adjustment function
(Incorporated in PX-24, PX-24ES, PX-23ES and PX-26 only)
The sensitivity can be adjusted, within the range set by the manual sen-
sitivity adjuster, by an analog voltage (0 to +5V) applied to the external
sensitivity adjustment input. The sensitivity varies with the magnitude of
the applied voltage.

Note: The extraneous light monitor output is not incorporated with a short-circuit protection circuit. Do
not connect it directly to a power supply or a capacitive load.

Extraneous light monitor function
(Incorporated in PX-24, PX-24ES, PX-23ES and PX-26 only)
If the sensor receives modulated light other than its own (including auxili-
ary sensor's) light, the extraneous light monitor output turns ON. The op-
eration of the extraneous light monitor output has absolutely no affect on
sensing. It is useful in recognizing presence of other sensors near this
sensor in case of intersecting AGV paths, etc.

External control function
(Incorporated in PX-24ES and PX-23ES only)
PX-24ES
and
PX-23ES
incorporate an external control function. Set the
external control function selection switch on the adjustment panel to
'EXT.' side. Then, the sensing area of the main sensor can be selected
by external signals.

Automatic interference prevention function
In case several sensors are used at the same place, take care that the
number of sensors from which beams may be simultaneously incident is
25 sensors or less.
Simultaneously incident beam
from up to 25 sensors.
Total of 26 sensors can be used at
the same place.
