Bar graph
In manual and automatic
bars indicate the set point deviation that de-
pends on the sign (+/–) and the value. One
bar element appears per 1 % set point devi-
ation.
If the positioner has not been initialized, (
blinks on the display), the bar graph indi-
cates the lever position in degrees in relation
to the mid-axis. One bar element corre-
sponds to approximately a 5° angle of rota-
tion. The fifth bar element blinks (reading >
30°) if the permissible angle of rotation has
been exceeded. Lever and pin position must
be checked.
