By confirming with ENTER, another relay
function already switched on is switched
off and its settings are reset to the factory
settings.

On = PID controller
Basic = basic load dosing
PID+B = PID cont basic load dosing
R232 Enter set point

0.000 mg/l
0.000 g/l
0.000 kg/l

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

0.01 to 20.00
See "P(ID) controller" section.
R234
Enter integral action

(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

v
(0.0 = no D-
component)

0.0 to 999.9 min
See "P(ID) controller" section.
R236
Select controller
characteristic inv = inverse
dir = direct
dir = Max. function
inv = Min. function
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.
