The following settings apply to the 3-point PID controller:
pH controller
parameters page 1
(3-point PID)
The set point (W) function is used to specify the nominal value within the measuring
range.
Value range (in dependence on set measuring range):
Measuring range
0..14 pH
2..12 pH
3..8 pH
The proportionality factors for the P-proportion of the respective controller can be
specified with the proportional area (XP1) and proportional area (XP2) functions.
Value range: 0 % to 999 %
The ID-proportion of the controller can be adjusted with the rate time (Tv) and reset
time (Tn) functions.
Value range: 0 sec to 1200 sec (prelim time)
Switching point 2 can be adjusted with the setpoint-difference(XSH) function.
Value range: 0 % to 20 %
Through selecting the module selection function one returns to controller parameter
module selection.
Page 2 displays additional parameters on a second page of settings.
The following settings apply to the 2-point-FUZZY controller:
pH controller
parameters page 1
(2-point FUZZY)
The set point (W) function is used to specify the nominal value within the measuring
range.
Value range (depending on the set measuring range):
Measuring range
0..14 pH
2..12 pH
3..8 pH
The FUZZY controller is informed of the system characteristic through the specified
delay time.
Value range: 0 sec to 60 sec
The set point difference (LW) function is used to specify the absolute interval between
switching point 2 and the set point.
Value range 0 pH to ±14 pH
