For analog models in high-contrast applications, alignment may be the only configuration needed. For more challenging applications us-
ing analog models, use the TEACH procedure to maximize contrast. This procedure is accomplished by pulsing the receiver’s white wire
(see
on page 7 and teach procedure on page 4). Analog output slope also can be inverted from positive to negative or back.
Sensor Alignment — When Empty Container Can Be Presented
1. Position both the emitter and the receiver loosely in their mount-
ing position. See Figure 2.
2. Present the “clear” condition for the application (an empty con-
tainer).
3. Verify that both emitter and receiver are wired for the same
modulation frequency (see below).
4. Adjust the emitter first, then the receiver. Adjust the emitter’s po-
sition until the receiver AID indicator is ON steady, or is flashing
at its fastest rate.
5. Tighten the emitter mounting hardware, then repeat step 4 for
the receiver.
6. Block the sensor beam with the target and verify that the output
changes state.
Figure 2. Sensor Alignment Procedure
Sensor Alignment — When Empty Container Cannot Be Presented
For this procedure, the clear condition is no container at all.
1. Mount loosely and mechanically align the emitter and the receiver such that their faces are parallel to one another. (The AID indica-
tor should be ON steady.)
2. Rotate the emitter in one direction until the receiver AID indicator begins to flash. Repeat in the other direction. Position the emitter
midway between those two positions and tighten the emitter mounting hardware.
3. Repeat step 2 for the receiver.
4. Block the sensor beam with the target and verify that the output changes state.
Frequency Selection
The modulation frequency (A or B) is selected by the state of the gray wire (on cabled models; pin 5 on QD models — see
page 7). A “+” voltage or no connection selects frequency A; connecting it to “–” selects frequency B. Each emitter must be set to the
same frequency as its receiver.
Emitter Inhibit
To disable (or inhibit) the emitter LED (useful for testing the receiver operation), connect the white wire to “–” voltage.
Analog Static TEACH
Analog TEACH is performed remotely, by pulsing the white Teach wire (see
Hookups).
Restore Factory TEACH: Reverts the sensing limits to the factory default limits
(max contrast); output slope is not affected.
Analog Output Slope: Toggles the analog output to send a high signal when
object is absent (positive slope) or present (negative slope). Analog slope can
be selected based on the TEACH order (first taught condition is always 0V; sec-
ond taught condition is 10V) or by using the slope select procedure below. If the
slope select procedure is used, it must be used after teaching the limits. To de-
termine the current slope setting, measure the output signal during object
present and absent conditions.
