The In Position type requires that the input be closed (grounded) at the end of the timing window
(the OFF setpoint) and then be open at some other point in the stroke. This message indicates that
the input never opened at any point in the stroke, thus indicating a possible failed or stuck sensor.
Section 5.1.2.5 1 Part Detector Messages
"Part was not seen during the Timing Window"
This input is programmed as a "1 Part Detector-Edge" which requires that the input be open
(ungrounded, no part in the detector) at the start of the timing window, then close at some point
before the end of the window (i.e., the part contacting the detector). This error message indicates
that one of these conditions was not met, signifying that the part was not seen and generating a stop.
"Part failed to completely pass during Timing Window"
This input is programmed as a "1 Part Detector-Pass" which requires that the input be open
(ungrounded, no part in the detector) at the start of the timing window, then close at some point
during the window (i.e., the part contacting the detector), then open again before the end of the
window. The system interprets this sequence of conditions from the sensor to indicate that a part
has completely passed through the detector during the timing window. This error message indicates
that one of these conditions was not met, signifying that the part was not seen and generating a stop.
"Input closed outside of Timing Window"
This input is programmed as a "1 Part Detector-Pass" which requires that the sensor cannot become
active outside the timing window. This requirement is made so that parts which are trapped and
vibrating on a probe-type detector will cause a fault rather than repeatedly satisfying the die
protection input every stroke. This error message indicates that the sensor became active (closed the
connection from input to ground) outside the timing window, violating the above requirement.
Section 5.1.2.6 2 Part Detector Messages
"First part not seen during Timing Window"
This input is programmed as a "2 Part Detector-Edge" which requires that the input be open
(ungrounded, no part in the detector) at the start of the timing window, close at some point during
the window (i.e., the first part contacting the detector), open again for the interval between parts,
then close again before the end of the window as the second part contacts the detector. This error
message indicates that the first open/close sequence was not seen thereby signifying that the first part
was not detected.
"Second part not seen during Timing Window"
This input is programmed as a "2 Part Detector-Edge" which requires that the input be open
(ungrounded, no part in the detector) at the start of the timing window, close at some point during
the window (i.e., the first part contacting the detector), open again for the interval between parts,
then close again before the end of the window as the second part contacts the detector. This error
message indicates that the first open/close/open sequence was seen but the final closure was not seen
