Experts in Chem-Feed and Water Treatment An Overview of Possibilities Dulcometer Disinfection Controller ( DDC )

Basic Version – Single System

Experts in Chem-Feed and Water Treatment Dulcometer Disinfection Controller  Basic version will be able to measure  pH  Free Chlorine  Total Chlorine – Display of combined chlorine  ORP  Temperature * either measure directly or from the Cl Sensor  Temp Compensation of pH signal – yes  pH compensated Free Chlorine – yes  Each of these parameters can be enabled / disabled through the programming menu. 3

Experts in Chem-Feed and Water Treatment Dulcometer Disinfection Controller  Basic version will be able to control  pH ( selectable acid or alkaline dosage )  Chlorine  Generate up to 4 x 4 – 20 mA output signals for measured variables  Powered output for duty cycle control of pH, Chlorine  ( for solenoid valve control or pump power control ) 4

Experts in Chem-Feed and Water Treatment Dulcometer Disinfection Controller  Sensors use CANBUS Interface (CAN = Controller Area Network )  CANBUS Interface is a proven technology used in the automobile industry. 5 ProMinent Express

Experts in Chem-Feed and Water Treatment New Sensors for Free and Total Chlorine  Sensors use CANBUS Interface (CAN = Controller Area Network )  Measuring Range 0.01 to 10 ppm  Auto Ranging provides excellent measurement resolution  Measurement of Free and Total chlorine  Calculation of combined chlorine 6

Experts in Chem-Feed and Water Treatment 3 Basic Modules  Basic unit consists of 3 electronic modules  Measurement Module ( M Module )  Actuating Module ( A Module )  Power Module ( P Module ) 8

Experts in Chem-Feed and Water Treatment Dulcometer Disinfection Controller Modules  Measurement Module 9 Power Module Actuating Module

Experts in Chem-Feed and Water Treatment Measurement Input Module (M module)  pH input ( via coaxial cable )  ORP input ( via coaxial cable )  Temp (PT 100) ( via 2 wire cable )  Temperature can come from PT 100 directly or from Cl Sensor ( from Cl sensor = no temp probe needed )  3 other contact inputs such as  Sample water flow  Pause (backwash)  UV limit 10

Experts in Chem-Feed and Water Treatment Output Actuating Module (A module)  3 Pulse outputs for metering pumps (such as acid, alkaline, hypo)  3 Inputs for fault relays from the metering pumps  4 x 4-20 analog outputs for measured variables 11

Experts in Chem-Feed and Water Treatment Power Module –P Module  Alarm Relay for horn, light, etc.  Power Relay 1- for Acid ( e.g. Solenoid valve)  Power Relay 2- for Alkaline ( e.g. Power to pump)  Power Relay 3- for Chlorine ( e.g. Solenoid valve ) 12
