Analog Sensor Instructions:
Teaching Set Point Limits
• The analog output mode returns a 4…20 mA or 0…10V DC
signal proportional to the measured value.
• The upper and lower adjustment range can be scaled to
distance-fixed window.
• The sensor is taught using an easy four-step remote teach
process or an optional programming cable.
• Two output functions: rising and falling ramp.
Rising Ramp: current or voltage values rise as the distance
increases between the target and the sensor.
Follow the steps below in the order they appear.
1. Place the target at the lower (near) set point limit.
2. Connect to 0V DC [–] using the white wire, or press A1 on the
optional programming cable.
3. Place the target at the upper (far) set point limit.
4. Connect to 10…30V DC [+] using the white wire, or press A2 on
the optional programming cable.
Falling Ramp: current or voltage values fall as the distance
increases between the target and the sensor.
Follow the steps below in the order they appear.
1. Place the target at the lower (far) set point limit.
2. Connect to 10…30V DC [+] using the white wire, or press A2 on
the optional programming cable.
3. Place the target at the upper (near) set point limit.
4. Connect to 0V DC [–] using the white wire, or press A1 on the
optional programming cable.
