Panel I/O’s
Panel inputs and outputs are the I/O’s pertaining to the machine operation panel and any option
panels the machine might have. These I/O signals communicate with the control via the CRP
board. A button being pressed on the machine operation panel is an example of a panel input.
An LED being turned on is an example of a panel output signal.
When an I/O signal is active (“high” or “1” or “true”), the signal name is shown in reverse
display. Signal names with a forward slash (/) indicate these signals are normally active signals.
This allows for quick diagnosis of a problem.
Spec Code
This menu shows which specification codes have been “turned on”. These codes activate soft-
ware files that are needed when certain options are purchased with the machine.
Machine Code
Only one of these machine codes will be on. This code tells the control what type of machine it
is controlling. If the maintenance person is not sure of the machine type he or she can look at
this menu to verify the type.
Machine Spec Code
These codes indicate the type of hardware applications or upgrades that have been added to the
machine. These modifications are usually done during assembly.
Alarm Message List
This page shows what type of alarms have occurred. CPU and “P” type alarms are not displayed
on this menu. The latest alarm is added to the top (No. 1) and the last one (No. 12) is dropped.
The list can be cleared by typing in ALMC and pressing the WRITE button. If an accurate time
is needed of when an alarm occurred, reset the time. The time and date can be reset by going
into the Edit Aux. mode and pressing the F1 function key for the date and the Extend function
key (F8) for the time.
