Chapter 1
The Muting Help dialog box shows
the proper timing sequence for 4
sensor, T-type muting. An object
must not only pass the sensors and
the light curtain in the proper
sequence. To initiate muting, an
object moving right to left in the
diagram must be in front of both
S1 and S2 for an instant. When
moving left to right, an object must
be in front of both S3 and S4, for
an instant. Take this timing and the
size of the load into consideration
when mounting the sensors. The
minimum load must be long
enough to be in front of both S1
and S2 or S3 and S4 sensors
simultaneously.
The Muting Help dialog box also provides definitions for the t(sens), t(espe), t(mute),
t(mdo), and t(msdel) times, which you can configure on the 4 sensor T-type dialog box. A
load that exceeds any of these configured times as it moves across the conveyor causes a
muting error, which results in the light curtain not being muted. A load entering the light
curtain sensing field during a muting error triggers a safe stop.
