Section 5.1.2 View Channel Status Messages
The Status block of the View Channel screen for any input (see Figure 2) will display information
regarding the present condition of that input and of the module in general. If the sensor wired to the
input is operating properly and the module has no error conditions present, the status block will read
"OK". If an error has been detected in the operation of the sensor wired to this input, an error
message will appear describing the failure that was detected. The specific message displayed will
depend on the die protection type for which this input is programmed. These messages are grouped
according to input type in the listings below. The operator must find the type for the input and then
look under that type heading below to locate the error message and its accompanying description.
If a failure occurs in the module itself (unrelated to the inputs or their sensors), a general status
message describing the failure will appear on the View Channel screens for every input. These
messages are listed under “General Status Messages” later in this section.
Section 5.1.2.1 Static Messages
"Input has closed - should stay open through stroke"
This die protection input is programmed as Static Normally Open which requires the input to remain
open (not grounded). If the input closes to ground for a time longer than the Delay Time
programmed, then this message is displayed indicating that the monitored condition has occurred
(i.e., stock buckle, etc.) and a stop is required. Check the monitored condition and correct if
necessary.
"Input has opened - should stay closed through stroke"
This die protection input is programmed as Static Normally Closed which requires the input to
remain grounded at all times. If the input opens (becomes ungrounded) for a time longer than the
Delay Time programmed, then this message is displayed indicating that the monitored condition has
occurred (i.e., end of stock, etc.) and a stop is required. Check the monitored condition and correct
if necessary.
Section 5.1.2.2 Cyclic Messages
"Input failed to close during Timing Window"
This error message occurs only when the stroke delay counter is set to zero; the Cyclic type then
requires the input to close (to ground) at some point during the timing window on every stroke. This
message indicates that the input was never grounded during the timing window, indicating that the
monitored event did not occur. Check the monitored condition and correct if necessary.
"Input failed to open outside Timing Window"
The Cyclic type requires the input to open (e.g., be released from ground) at some point outside the
timing window. On this stroke the input was grounded through the entire stroke, possibly indicating
