5.4 Dosing
NMC-Pro includes 10 predefined dosing programs. Each program consists of injection methods, quantities and EC/pH
target values. Each channel is completely independent and can be set to give a different amount. Overlapping
between the various channels is possible.

5.4.1 Dosing Program
• Program: Select a program by entering the program number, and confirm by pressing ENTER.
• EC Pre-Control:

On: EC Pre-Control is active for this Dosing program.

Off: EC Pre-Control is not active for this Dosing program; the EC Pre-Control valve will be shifted
towards the fresh water source.
INJECTION PER DOSING CHANNEL
• Dosing channel number: 1 to 8.
• Reaction: A read only line indicating the purpose of the channel;

EC: the channel is used to increase measured EC, meaning it will be opened more when the measured
EC is lower than the set EC.

pH: the channel is used to decrease measured pH, meaning it will be opened more when the measured
pH is higher than the set pH.

Passive: the channel does not respond to changes in measured EC/pH, meaning it will be opened as
set in the Dosing program regardless of the EC/pH values.

Alkali: the channel is used to increase measured pH, meaning it will be opened more when the
measured pH is lower than the set pH.
• Quantity / Time: Set the Quantity / Time to be injected for each dosing channel. The injection method
(proportional, quantity, time, etc.) can be set separately for each use of the channel (EC, pH, Passive).
• Target EC: Set the required EC target value, only visible if EC control or EC alarms are active, see table 1.3.
• Target pH: Set the required pH target value, only visible if pH control or pH alarms are active, see table 1.3.
• Target EC Pre-Control: Set the required EC Pre-Control target value (only visible if EC-Pre Control is set to
On, see EC-Pre Control above).
• Passive Dosing Method: Set the required injection method of the Passive dosing channels (see
Dosing
injection method).
• EC Dosing Method: Set the required injection method of the EC dosing channels (see Dosing injection
method).
• pH Dosing Method: Set the required injection method of the Acid and Alkali dosing channels (see Dosing
injection method).
