tracking time being set for too small a value for this operation.
"Input did not close in time after PLS turn 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 PLS output turned on and
the tracking time expired before the input closed (to ground) in response. This could be caused by
a failure of the mechanism being monitored, a failure of the sensor, a loose wire from the sensor, or
by the tracking time being set for too small a value for this operation.
Section 5.1.2.8 Track PLS Invert Messages
"Input opened before PLS Output turned On - Invert"
This input is programmed as a Track PLS Invert type so that the input must inversely follow the PLS
channel programmed under "Track PLS Channel" (i.e., the input should open when the PLS output
turns on). This message indicates that the input opened (became ungrounded) without the PLS
output turning on to initiate this 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 Off - Invert"
This input is programmed as a Track PLS Invert type so that the input must inversely follow the PLS
channel programmed under "Track PLS Channel" (i.e., the input should close when the PLS output
turns off). This message indicates that the input closed (became grounded) without the PLS output
turning off to initiate this 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 On"
This input is programmed as a Track PLS Invert type so that the input must inversely follow the PLS
channel programmed under "Track PLS Channel" (i.e., the input should open when the PLS output
turns on). This message indicates that the PLS output turned on 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 tracking time being set for too small
a value for this operation.
"Input did not close in time after PLS turn Off"
This input is programmed as a Track PLS Invert type so that the input must inversely follow the PLS
channel programmed under "Track PLS Channel" (i.e., the input should open when the PLS output
turns off). This message indicates that the PLS output turned off and the tracking time expired
before the input closed (to ground) in response. This could be caused by a failure of the mechanism
being monitored, a failure of the sensor, a loose wire from the sensor, or by the tracking time being
set for too small a value for this operation.
