IMPORTANT: Save these instructions for futu re use.

IMPORTANT: Solid state devices can be

susceptible to radio frequency (RF)

interference depending on the

power and the frequency of the

transmitting source. If RF

transmitting equipment is to be used

in the vicinity of the solid state

devices, thorough testing s hould be

performed to assure that transmitter

operating distance from the sensor

equipment and its wiring.

ATTENTION: If a hazardous condition ca

result from unintended operation of this

device, access to the sensing area should

be guarded.

Description

Bulletin 873P Programmable Ultrasonic Sensors are

self-contained solid-state devices designed for noncontact

sensing of solid and liquid objects.

These sensors have two programmable setpoints with

sourcing (PNP) outputs that can be configured for either

normally open or normally closed operation. The setpoints

can be programmed to switch the discrete output at any

target position within the sensor’s range. In addition, they

also feature either a 4--20mA or 0--10V DC analog output

depending on the model. The slope of the analog output is

scaled between the limits of the setpoint values.

Programming of the setpoints and the output configuration

is done using the setup pushbutton on the rear of the

housing. These devices can be useful for many applications

including: level control, diameter measurement, distance

measurement, and presence detection.

Programming G Place the target at the P2 position and depress the pushbutton to set the P2 switchpoint. For a normally open output depress with the P2 LED “ON”; for a normally closed output depress with the P2 LED “OFF.” These sensors will require programming using the pushbutton at the rear of the sensor.

Target Considerations result, consideration should be given to the sensor spacing. See the beam pattern chart for the minimum acceptable distance between sensors that are mounted side by side. When the sensors must be mounted facing each other they should be separated by a distance at least four times the maximum sensing range for the model.
