Operating Voltage

Double Discrete Outputs

These sensors feature two programmable independent set points
with sourcing (PNP) outputs that can be configured for normally
open (N.O.) or normally closed (N.C.) operation.

Window Function

In this sensing mode, you teach the sensor a near set point and a
far set point within the defined sensing range of the sensor. P1
and P2 define the analog output slope. P1 determines the 4 mA
position and P2 determines the 20 mA position.

With normally open logic, if an object passes through the defined
window, the discrete output turns ON or the opposite if the logic
is normally closed. The analog output is scaled between the two
taught set points.

Set Point 1 (P1):

1. Place the target at the desired near/far set point.

a. The near set point first yields a normally open/rising ramp.

b. The far set point first yields a normally closed/falling ramp.

2. With the target still in place, press the teach button, then

release.

The yellow and green LEDs flash simultaneously, indicating that
the first set point P1 is now set. The sensor is waiting for the last
set point.

Set Point 2 (P2):

1. Place the target at the desired near/far set point.
2. Press the teach button and release while the green and yellow

LEDs blink five times. The sensor is ready to operate.
