FORCING MENU

62

Pressing the ESC key will exit the
Forcing mode without altering
anything that has not been changed
up to this point. The PCDU will
return to the screen showing
the initial value for the selected PAC
block:

(NUMI PAC BLOCK)

(LOGO PAC BLOCK)

OR

Note: When the ESC key is pressed

repeatedly in any menu, the PCDU
will back up all the way to the top
greeting message. The FRC menu
is an exception to this rule. This is
done to minimize the possibility
of the operator leaving the I/O in
the forcing mode without knowing
it. If the ESC key is pressed
repeatedly and there is at least one
I/O currently being force, the PCDU
will display the following screen:

This is how the PCDU informs the
operator that there is at least one
PAC block in the forcing state. It is
assumed that the operator has read
the “Forcing active....” message and
therefore is aware of this fact after
the F3 key is pressed.
