display.
Action Result

"RMT TCH" and the target's measurement value
display.
Action Result
Single-pulse the remote input.
"Tch4mA (Tch0V) Teaching" displays while the
sensor is being taught.
TEACH Accepted
The new value displays on the second line of the
display, flashes, and then "Tch20mA (Tch10V)" and
the current measurement value display.
TEACH Not Accepted
"FAIL" flashes, the sensor returns to step 2, and
"RMT TCH" displays.
Action Result
Present the 20 mA (10 V) target.
"Tch20mA (Tch10V)" and the target's measurement
value display.
Action Result

Figure 6: Window and Midpoint Example
The Midpoint TEACH uses both the window size and the 12 mA (5 V) setpoint to
determine the actual measurement window. For example, a window of 200 mm with a
12 mA (5 V) setpoint of 600 mm places the measurement window from 500 mm to 700
mm.
To use the Midpoint TEACH:
1) Set the window size.
2) Set the measurement window using TEACH 12 mA (5 V) on page
12.
The Analog Output Midpoint TEACH and the Discrete Output Midpoint TEACH are
independent settings (see Midpoint TEACH on page 18).
