ProMinent DULCOMETER diaLog DACb User Manual

4 Functional Description
The DULCOMETER
®
Multi-parameter Controller diaLog DACb is a
controller platform manufactured by ProMinent.
In the remainder of this document, the term
‘controller’ is consistently used for the
DULCOMETER
®
. The controller has been
developed for continuous measurement and
control of liquid analysis parameters. For water
treatment processes in environmental tech‐
nology and industry. The controller is available
in a version with 2 or 3 measuring channels.
The controller can operate together with con‐
ventional analogue sensors and actuators. The
controller is equipped to communicate with dig‐
ital sensors and actuators via the CANopen
sensor/actuator bus.
Typical applications:
n Potable water treatment,
n Waste water treatment,
n Industrial and process water treatment,
n Swimming pool water treatment.
Standard equipment:
n 1 measuring channel with 14 freely select‐
able measured variables (via mV or mA
input) – depending on the identity code.
n PID controller with frequency-based
metering pump control for 2 metering
pumps.
n 2 analogue outputs for measured value,
correction value or control variable
(dependent on the optional equipment).
n 4 digital inputs for sample water fault
detection, pause and parameter switch-
over.
n 2 relays with limit value functions, timer
and non-continuous control, 3-point step
control (dependent on the optional equip‐
ment).
n Power supply 20 V DC.
n Measured variables and language selec‐
tion during commissioning.
n Temperature compensation for the pH and
fluoride measured variables.
n 22 operating languages.
n Saving and transfer of device parametrisa‐
tion to an SD card.
n Subsequent upgrade of the software func‐
tion by means of an activation key or firm‐
ware update.
n Disturbance variable processing (flow) via
frequency.
n Measured value trend display via the con‐
troller display.
Optional accessories:
n Third complete measuring and control
channel with 14 freely selectable meas‐
ured variables (via mV or mA input).
n PC configuration software.
n Data and event logger with an SD card.
n Disturbance variable processing (flow)
also via mA.
n Compensation of the influence of pH on
chlorine measurement.
n 3 additional digital inputs, e.g. for level
monitoring.
n PROFIBUS
®
-DP *.
n Modbus-RTU.
n PROFINET
®
.
n Visualisation via LAN/WLAN web access.
