Operating Instructions
Version 1.5
H) Kp
Proportional component for the PID controller.
I) Tn
Integral component for the PID controller.
J) Tv
Differential component for the PID controller.
K) Type
Reserved for special applications.
L) Application
Reserved for special applications.
M) Offset
Deviation at the residual oxygen display can be compensated for with the
offset function.
N) Hysteresis
Tolerance evaluation performance can be adapted with the hysteresis
function.
O) Base Level Factor
• If the basic level factor is 0, the basic valve is actuated just like the
control valve.
• If the basic level factor lies within a range of 1 to 223, the basic valve
is coupled to the control valve via a filter function. Time „ta“ plays a
role in this respect. The duration of time during which filtering takes
place is calculated with the following formula
tf = ta x 100 ms x basic level factor
Example: ta = 20, basic level factor = 6 (time for mean value
generation)
tf = 20 x 100 ms x 6 = 12s
• If the basic level factor is 224 with a 6 bar valve or
if the basic level factor is 327 with a 2 bar valve,
the basic valve is actuated directly by means of the basic level.
• The entry under Base Level in the menu Masks is scaled with this
factor (submenu for N2 operating mode, see chapter 5.5.10 in the
operating instructions).
