U-GAGE T30 Series Overview
The U-GAGE is an easy-to-use ultrasonic sensor, ideal for demanding environments.
Simple push-button programming provides flexibility for a variety of applications.
Excellent for measurement applications such as sensing of liquid levels in a tank or, for
example, determining box heights for sorting purposes.
Each sensor includes both an analog and a discrete output, which may be programmed
independently with different window limits or together with identical limits. Each output
has the option of being set with a sensing distance set point centered within a 10-mm
window.
U-GAGE T30 Series Programming
Window Limits
Window limits may be taught to the sensor in several ways. The following methods
describe the programming procedures using the push buttons on the back of the
sensor; remote programming (remote TEACH) procedures are described on page 4.
NOTE: When the sensor changes state between PROGRAM and RUN modes, all of the
LED indicators turn OFF momentarily, before the appropriate LEDs come ON as
described below. The sensing window limits expand temporarily to full scale
(max range) during PROGRAM mode.
Teaching Limits for Either Analog or Discrete Output
1. Choose the output for the first set of window limits (analog or discrete) and push
and hold the corresponding button until the green Power LED goes OFF and the
appropriate yellow Output LED turns ON (solid). This indicates the sensor is waiting
for the first limit.
2. Position the target for the first limit and briefly “click” the same button. This will
teach the sensor the first limit. The yellow Output LED will flash to acknowledge
receiving the first window limit; it is now waiting for the second limit.
3. Position the target for the second limit and “click” the button again. This will teach
the sensor the second limit. The yellow Output LED turns OFF and the green Power
LED comes ON; the sensor is now in normal RUN mode.
4. Repeat for the other output (analog or discrete) if a second output is desired.
NOTE: Press and hold the same button > 2 seconds (before teaching the second limit)
to exit PROGRAM mode without saving any changes. The sensor will revert to
the last saved program.
Teaching Analog or Discrete Limits Using the Auto-Zero Feature
For some applications, a sensing distance set point centered within a minimum sensing
window may be required. The TEACH procedure for this application is simple: teaching
the same limit twice causes the sensor to program a 10-mm window centered on the
position taught (position ±5 mm).
NOTE: The sensor allows for some forgiveness in this procedure. If the two limits are
not exactly the same (but closer than the minimum 10-mm window required),
the sensor will put the set point at the “average” of the two limits.
