4.2 Configuration parameters
Configuration level
Configuration parameters 30 KS 90-1 / KS 92-1
Cntr
Name Value range Description Default
SP.Fn
Basic configuration of setpoint processing 0
0 set-point controller can be switched over to external set-point
(-> LOGI/ SP.E)
8 standard controller with external offset ( SP.E)
C.tYP
Calculation of the process value 0
0 standard controller (process value = x1)
1 ratio controller (x1/x2)
2 difference (x1 - x2)
3 Maximum value of x1and x2. It is controlled with the bigger
value. At sensor failure it is controlled with the remaining
actual value.
4 Minimum value of x1and x2. It is controlled with the smaller
value. At sensor failure it is controlled with the remaining
actual value.
5 Mean value (x1, x2). With sensor error, controlling is
continued with the remaining process value.
6 Switchover between x1 and x2 (-> LOGI/ I.ChG)
7 O
2
function with constant sensor temperature
8 O
2
function with measured sensor temperature
C.Fnc
Control behaviour (algorithm) 1
0 on/off controller or signaller with one output
1 PID controller (2-point and continuous)
2
D / Y / Off, or 2-point controller with partial/full load
switch-over
3 2 x PID (3-point and continuous)
4 3-point stepping controller
5 3-point stepping controller with position feedback Yp
6 continuous controller with integrated positioner
C.dif
Output action of the PID controller derivative action 0
0 Derivative action acts only on the measured value.
1 Derivative action only acts on the control deviation
(set-point is also differentiated)
mAn
Manual operation permitted 0
0 no
1 yes (r LOGI / mAn)
C.Act
Method of controller operation 0
0 inverse, e.g. heating
The correcting variable increases with decreasing process
value and decreases with increasing process value.
1 direct, e.g. cooling
The correcting variable increases with increasing process
value and decreases with decreasing process value.
