8.2 Current Output
P08: Fixed current output
FACTORY DEFAULT: 0
By this step the output current can be set for a fix value selected from between 3.8
mA and 20.5 mA. This function is not operational as per the factory default: 0.
Attention: fixing output current will make settings in P10, P11, P12 and P19
irrelevant.
P10: Value (of distance, level, volume or flow) assigned to 4 mA current
output
FACTORY DEFAULT: 0
P11: Value (of distance, level, volume or flow) assigned to 20 mA current
output
FACTORY DEFAULT: X
M
– X
m
Values are interpreted according to
P01(a)
. 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. level 1 m assigned to
4mA and level 10 m assigned to 20 mA represents direct proportion and level 1 m
assigned to 20 mA and level 10 m assigned to 4 mA represents the inverse
proportion. 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
