General Notes on Programming

• The sensor will return to Run mode if the first Teach condition is not registered

within 120 seconds.

• After the first limit is taught, the sensor will remain in Program mode until the Teach

sequence is finished.

• To exit Program mode without saving any changes, press and hold the programming

push button > 2 seconds (before teaching the second limit). The sensor will revert to

the last saved limits.

Analog Output Slope:

The U-GAGE S18U sensor may be programmed for either a positive or a negative

output slope, based on which limit is taught first (see Figure 3). If the Near limit is

taught first, the slope will be positive. If the Far limit is taught first, the slope will be

negative. Banner’s scalable output automatically distributes the output signal over the

width of the programmed sensing window.

In the event of signal loss, the analog output goes to 3.6 mA or 0V dc, which may be

used to trigger an alarm.
