Registration Mark Sensors
Static TEACH
In Static TEACH mode, the sensor learns two sensing conditions after each is presented one
time. The sensor automatically positions the switchpoint midway between the two conditions.
See Figure 3.
NOTE: The sensor will return to RUN mode if either TEACH condition is not registered within
60 seconds. TEACH mode may be cancelled by pressing and holding the Static push
button for ≥ 2 seconds. In either case, the sensor will revert to the previous conditions
taught (i.e., exit without save).
Static TEACH and Manual Adjust
Sensitivity may be adjusted at any time when the sensor is in RUN mode by clicking the “+”
and “-” buttons. Each click translates to 1/2 segment on the signal strength bargraph display.
For best sensing reliability, both sensing conditions should register equally distant from the
switchpoint on the signal strength bargraph display.

Access
TEACH
Mode
• Push and hold the Static
push button for
> 2 seconds.
• No action required; sensor
is ready for the 1st sensing
condition.
(push button only)
LO and DO: Alternately flash Green
Output: ON Yellow (indicating ready to teach 1st sensing condition)
Bargraph display: Goes OFF
Teach
1st
Sensing
Condition
• Present the 1st sensing
condition.
• “Click” the Static push
button.
• Present the 1st sensing
condition.
• Single-pulse the remote line.
• Wait at least 0.8 seconds.
LO and DO: Alternately flash Green
Output: OFF (indicating ready to teach 2nd sensing condition)
Bargraph display: Remains OFF
Teach
2nd
Sensing
Condition
• Present the 2nd sensing
condition.
• “Click” the Static push
button.
• Present the 2nd sensing
condition.
• Single-pulse the remote line.
Teach Accepted
• Bargraph display flashes one segment for three seconds to indicate
relative contrast (see contrast table on page 5).
• Sensor enters RUN mode.
Teach Unacceptable
• Pairs of bargraph display segments flash for three seconds to indicate low
contrast.
• Sensor returns to TEACH 1st sensing condition.
