R2 (3)
Configure P(ID)
controller
LC PV = limit contactor cond
(1)
LC °C = limit contactor T (2)
PID controller (3)
Timer (4)
Clean = Chemoclean (5)
USP (6)
EP PW (7)
By confirming with ENTER, another relay
function already switched on is switched
off and its settings are reset to the factory
settings.
R231
Switch function of
R2 (3) off or on
Off
On
Basic
PID+B
On = PID controller
Basic = basic load dosing
PID+B = PID controller + basic load dosing
R232 Enter set point
cond/ind: 0.00 mS/cm
MOhm: 0.00 kcm
conc: 0.00 %
The set point is the value to be maintained
by the control system. Using this control
process, this value is restored upwards or
downwards when a deviation occurs.
R233 Enter control gain K
p
1.00
0.01 to 20.00
See "P(ID) controller" section.
R234
Enter integral action
time T
n
(0.0 = no I-
component)
0.0 min
0.0 to 999.9 min
See "P(ID) controller" section.
With every Hold, the I-component is set to
zero. Although Hold can be deactivated in
field S2, this does not apply for
Chemoclean and timer!
R235
Enter derivative
action time T
v
(0.0 = no D-
component)
0.0 min
0.0 to 999.9 min
See "P(ID) controller" section.
R236
Select controller
characteristic
dir = direct
inv = inverse
The setting is required depending on the
control deviation (upward or downward
deviation, see "P(ID) controller" section).
R237
Select pulse length
or pulse frequency
len = pulse length
freq = pulse frequency
curr = current output 2
Pulse length e.g. for solenoid valve, pulse
frequency e.g. for solenoid dosing pump,
see "Actuating signal outputs" section.
Curr = current output 2 can only be
selected if O2 = Contr.
R238 Enter pulse interval
10.0 s
0.5 to 999.9 s
This field only appears if pulse length is
selected in R237.
If pulse frequency is selected, R238 is
skipped and entries continue with R239.
