2 Functional Description
Brief functional description
The DULCOMETER ® D1Cb 4-wire measuring transducer/control is a device designed to measure/
control a measured variable.
In the mA measuring version, the measured variable can be changed without restrictions in the menu
of the device. In the mV measuring version, it is only possible to select between pH and redox in the
menu of the DULCOMETER ® D1Cb .
Depending on the measured variable, sensors for pH or redox potential or amperometric sensors can
only be connected to the measured variables in line with the Ä Table “Table of measured variables:
Assignment of the measured variable to the measuring input of the DULCOMETER ® D1Cb ”
on page 14 . The temperature measurement serves as a correction variable and can be measured
using a Pt 100/1000. This means that automatic temperature compensation is possible with pH-
value, conductivity and fluoride measured variables. Temperature compensation is performed in the
sensor (with the exception of the chlorine dioxide sensor type CDP) with amperometric measured
variables (chlorine etc.). The DULCOMETER ® D1Cb is operated using menu keys and the data is
displayed by means of an illuminated LCD display. The LCD display ensures that the reading, correc‐
tion variable, actuating variable and error messages can be clearly read.

2.1 Wall Mounted/Control Panel
Mounted
The DULCOMETER ® D1Cb W is suitable both
for wall-mounting, as well as for mounting on a
control panel (with additional control panel fixing
set).
The plastic housing comprises a housing upper
section and lower section. The LCD display and
membrane keypad are accommodated in the
upper section of the housing.
The lower section of the housing accommodates
the processor and power units and any optional
assemblies. A ribbon cable connects to the LCD
display and the membrane keypad.
The electrical connection is made through origi‐
nally sealed, push-out cable cut-outs on the
underside of the lower section of the housing.
A wall bracket for wall mounting is located on the
rear of the lower section of the housing.
Functional Description
15

2.2 Electrical Design
The device does not have a mains power
switch. It is therefore immediately ready for
operation once connected to the power supply.
The device processes an input signal whilst
taking into consideration operator inputs. The
result is displayed and made available to other
devices via a standard signal. When equipped
with actuators, the device can also provide
control functions. It is designed to activate
metering pumps, solenoid valves, as well as an
mA standard signal output. The activation vari‐
able is recalculated every second.
