-- EC300A/EC400 Inputs Screen #1 --
This screen shows the unit number of the control which is being addressed (see page 30 for more
discussion on multiple motor carriages) as well as the unit type, the revision number of the
software, the carriage number the control is on and the operational state of the unit. It also
indicates the cause of the last carriage stop (see table below). While any of these five screens is
being displayed, pressing NEXT will display information on the next controller in the
communication line (in this case unit 3). Pressing LAST will display information on the
previous unit in the communication line (in this case unit 1). Using this screen to sequence
through all the units is helpful, for example, in locating the controller with the mismatched
software revision. Pressing the DOWN key will display the next screen of information, which is
shown at the bottom of this page.

This screen displays the status of the move and reset buttons on each control head of the carriage
control. When these switches on the face panel control are activated, the "Open" status displayed
on the screen should change to a "Closed" status. The NEXT and LAST keys change to the next
and previous controls in the communication chain, while the DOWN key will display the
following screen. And the up key will return to the previous screen.
