a failed or stuck sensor.
“Input failed to close throughout stroke delay”
This error message occurs only when the stroke delay counter is set to some number other than zero.
When this is true, the input is not required to close (to ground) within the timing window on every
stroke, but it must close within the window on at least one stroke before the number of strokes
entered in the counter has passed. This error message indicates that the input was never grounded
within the timing window during the consecutive number of strokes entered into the counter. Check
the monitored condition and correct if necessary.
Section 5.1.2.3 Transfer Messages
"Input was not closed at start of Timing Window"
The Transfer type requires that the input be closed (grounded) at the beginning of the timing
window, all during the window, and at the end of the window; and then open at some point outside
the window. However, the input was not closed at the beginning of the timing window (the ON
setpoint) indicating that the part was not gripped properly and therefore requiring a stop.
"Input did not stay closed during Timing Window"
The Transfer type requires that the input be closed (grounded) at the beginning of the timing
window, all during the window, and at the end of the window; and then open at some point outside
the window. However, the input did not remain closed during the entire timing window indicating
that the part was dropped and therefore requiring a stop.
"Input was not closed at end of Timing Window"
The Transfer type requires the input to be closed (grounded) at the end of the timing window (the
OFF setpoint). However, the input was not closed at the end of the window indicating that the part
was not gripped properly and therefore requiring a stop.
"Input failed to open outside Timing Window"
The Transfer type requires the input to open (be released from ground) at some point outside the
timing window. On this stroke the input did not open outside the timing window, possibly indicating
a failed or stuck sensor.
Section 5.1.2.4 In Position Messages
"Input was not closed at end of Timing Window"
The In Position type requires that the input be closed (grounded) at the end of the timing window
(the OFF setpoint). However, the input was not closed at the end of the window indicating that
material was not in position and therefore requiring a stop.
"Input failed to open at any point in the stroke"
