Procedure
Press pushbutton (6) for about 6 seconds until
"PS" starts to flash. Release pushbutton -- "onPA"
displayed (Selection Level). Blocked if digital si-
gnal bLPS=1.
Press pushbutton (15) several times
until "oFPA" is displayed (Selection Level).
Blocked if digital signal bLS=1.
Press pushbutton (11) for about 3 seconds
(Configuring Level). Controller is now blocked and,
the most recent value of y will be retained.
Using pushbutton (7) or
ter names from y digital indicator (9).
Using pushbutton (15) or
ters values in the w/x digital indicator (3).
Repeat steps 4 and 5 until all desired parameters
are set.
Press pushbutton (16) once (Selection Level).
Press pushbutton (16) once (Process Control
Level). Controller is now in manual mode.
