KH actual value
Calculated volume change for pump 6 per single dosing
7,5° dKH
+10 % = 220 ml
8,0° dKH
+5 % = 210 ml
8,5° dKH
0 % = 200 ml
–
no change, KH value fits
9,0° dKH
-5 % = 190 ml
9,5° dKH
-10 % = 180 ml
(the maximum
Volume change
can be limited with the limit settings)
The
Calculated adjustment
affects the dosages of this dosing pump until the next KH
measurement.
Please note the following when setting these and all other limits:
6.2
Control via reactor: Calcium reactor mode
This mode is only available if there is pH control (via ProfiLux 3 or 4) in the system.
Depending on the difference KH setpoint to KH actual value (= control difference), the pH
setpoint of a reactor can be influenced (for example, by switching a CO2 solenoid valve).
First, the pH sensor is selected for its regulation, then the following parameters must be set:
•
Nominal value change
(in pH)
If the KH actual value is too low by 1° dKH, then the pH setpoint is reduced by this
value
.
DANGER
•
In any case, safe limits must be set.
•
The limits must be chosen so, that the amounts varied by the KH
regulation have any chance of correcting the KH value.
•
On the other hand, in the case of a malfunction (for example,
incorrect measurement because reagent is empty), the amounts
should not become so high that they could endanger the aquarium.
•
There is no plausibility check of the settings you have made.
•
The manufacturer disclaims any responsibility or liability for
damages!
