thereby signifying that the second part was not detected.
"First part did not pass completely during Timing Window"
This input is programmed as a "2 Part Detector-Pass" which is identical to the "2 Part Detector-
Edge" type except that the second part seen must completely pass the detector (i.e., the input must
finish open or ungrounded when the timing window ends). This error message indicates that the first
open/close/open sequence was not seen thereby signifying that the first part did not pass completely
through the detector.
"Second part did not pass completely during Timing Window"
This input is programmed as a "2 Part Detector-Pass" which is identical to the "2 Part Detector-
Edge" type except that the second part seen must completely pass the detector (i.e., the input must
finish open or ungrounded when the timing window ends). This error message indicates that the first
open/closed/open sequence was seen (signifying that one part was detected) but that the second
closed/open sequence was not seen, thereby signifying that the second part did not pass completely
through the detector.
"Input closed outside of Timing Window"
This input is programmed as a "2 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 5.1.2.7 Track PLS Messages
"Input opened before PLS Output turned Off"
This input is programmed as a Track PLS type so that the input must follow the PLS channel
programmed under "Track PLS Channel". This message indicates that the input opened (released
from ground) without the PLS output turning off to initiate this input action. This could be caused
by a failure of the mechanism being monitored, a failure of the sensor, or a loose wire.
"Input closed before PLS Output turned On"
This input is programmed as a Track PLS type so that the input must follow the PLS channel
programmed under "Track PLS Channel". This message indicates that the input closed (to ground)
without the PLS output turning on to initiate this input action. This could be caused by a failure of
the mechanism being monitored or a failure of the sensor.
"Input did not open in time after PLS turn Off"
This input is programmed as a Track PLS type so that the input must follow the PLS channel
programmed under "Track PLS Channel". This message indicates that the PLS output turned off and
the tracking time expired before the input opened (e.g., released from ground) in response. This
could be caused by a failure of the mechanism being monitored, a failure of the sensor, or by the
