Schneider Electric SM556A-100FSN Hyde Park Superprox Ultrasonic Proximity Sensor

Description

Schneider Electric SM556A-100FSN Hyde Park Superprox Ultrasonic Proximity Sensor.
Ultra-sonic sensor; field adjustable limits; 39″ max range; 15-24 vdc; analog output; Mini quick-disconnect
Four slide switches, one pushbutton, and a potentiometer (Fig. 2) are located inside a watertight compartment. To access the switches, pushbutton, and potentiometer, loosen the two flathead screws and insert a small-blade screwdriver in either the top or bottom slot to remove the cover.
Configuration Switches
Switch 1 selects either directly or inversely proportional analog output.
​DIR for proportional output
​(Maximum analog output occurs close to sensor)
​INV for inverse proportional output
​(Minimum analog output occurs close to sensor)
Switch 2 selects the desired analog output on loss of echo.
​MIN for minimum analog output on loss of echo
​MAX for maximum analog output on loss of echo
Switch 3 is not used.
Switch 4 is not used.
LIMITS Pushbutton
The LIMITS pushbutton is used to set the analog span limits and is explained in the Setup Procedure on Page 5.
RESPONSE Potentiometer
The RESPONSE potentiometer sets the response time of the analog output to changes in the distance to the object (Figure 4, Page 3).

Operation
With Switch 1 set to DIR, the analog value is proportional to the distance to the object and is at a maximum when the object is at or closer than the near limit. With Switch 1 set to INV, the analog value is inversely proportional to the distance to the object and is at a maximum when the object is at or farther than the far limit.
Loss of Echo
Loss of echo occurs when the sensor does not receive any echoes within its sensing range for more than one second. On loss of echo the analog output goes to the value selected by Switch 2.
Analog Response Time Potentiometer
A one-turn RESPONSE potentiometer, located in the control compartment, determines how fast the analog output changes for a change in distance to the object. This response setting dampens the analog output from rapid changes in the object distance due to erratic object movement or irregular object patterns.
Figure 3 below shows the analog response based on the setting of the RESPONSE potentiometer.
The analog response is the time required for the analog output to reach 95% of the steady state analog value. Figure 4 below shows the analog output curves for two RESPONSE potentiometer settings. The response time is variable from 0.07 to 2.5 seconds.

Mounting
Mount the sensor firmly so that the material to be detected is never within 50.8 mm (2.00 inches) of the face of the sensor. For best results the sensor face should be parallel to the liquid or material surface. Also the sensor should be away from air currents.

Setup Procedure
Set the first two configuration switches to the position required for the desired operation, and then apply power to the SUPERPROXÒ sensor. The last two configuration switches are not used.
Setting the Analog Span Limits
Align a flat object parallel to the sensor face at the desired distance position for either limit and press the LIMITS pushbutton once. Upon release of the pushbutton, the multicolor LED flashes amber, indicating the first limit is set and the sensor is waiting for the second limit to be set. Align a flat object parallel to the sensor face at the desired position for the second limit and press the LIMITS pushbutton once. Upon release of the pushbutton, the multicolor LED turns to the color that indicates where the object is located within the sensing range. If the second limit is not set within 30 seconds after setting the first limit, both limits revert back to the previous limit settings.
While the LIMITS pushbutton is depressed, the multicolor LED turns amber to indicate the sensor detects the object. If the sensor does not detect the object, the multicolor LED is red while the LIMITS pushbutton is depressed. When the LIMITS pushbutton is released after not detecting an object, the multicolor LED flashes red until either the LIMITS pushbutton is pressed again for the first limit or 10 seconds have elapsed. After 10 seconds have elapsed, the analog limits revert back to the previous settings. If the limits are not accepted, repeat the setup procedure until the limits are accepted.
The limits are stored in nonvolatile memory and thus are retained when power is removed from the sensor.
Setting the RESPONSE Potentiometer
Adjust the RESPONSE potentiometer based upon how fast the analog output should change for changes in the distance to the object. Figure 3 on Page 3 shows the response time based on the RESPONSE potentiometer setting.
