Current Output
P10:
Value (of distance, level, volume or flow) assigned to 4 mA current output
P11:
Value (of distance, level, volume or flow) assigned to 20 mA current output
Values are interpreted according to
P01(a)
. Please note that in case of programming for (LEV or VOL) % measurement the min and max value
has to be entered in the relevant engineering units of LEV (m, ft) or VOL (m
3
, ft
3
).
Assignment can be made so that the proportion between the change of the (measured or calculated) process value and the change of the current
output be either direct or inverse. E.g. lev 1 m assigned to 4mA and lev 10 m assigned to 20 mA represents direct proportion and lev 1 m
assigned to 20 mA and lev 10 m assigned to 4 mA represents the inverse proportion.
FACTORY DEFAULT:
P10 0 level (max distance)
P11 max level (min distance) H
P12: - - - a
