General User Information
These operating instructions describe the technical data and function of the series DULCOMETER®D2C
controller, provide detailed safety information and are divided into clear steps. The activities to be carried
out are identified by arrows ( ).
IMPORTANT
• Please observe the parts of these operating instructions applicable to your particular
version! This is indicated in the Section “Device Identification/Identity Code”.
• Correct measuring and dosing is only possible in the case of impeccable operation of the
probe. The probe has to be calibrated/checked regularly!
• In the event of a probe failure, uncontrolled chemicals addition may result. We therfore
recommend urgently to activate “check out time limits” with automatic control shut-off!

4 Functional Description
NOTE
Please refer to the description of the operating menu for a detailed description of the
individual characteristics of the DULCOMETER®D2C controller!
4.1 Operating Menu
The DULCOMETER®D2C controller permits settings to be made in two different menus. All values are
preset and can be changed in the complete operating menu.
The controller is delivered with a restricted operating menu so that the D2C controller can be used
effectively in many applications from the very onset. If adaptations prove to be necessary, all relevant
parameters can then be accessed by switching over to the complete operating menu.
4.2 Access Code
Access to the setting menu can be prevented by setting up an access code. The D2C controller is supplied
with the access code 5000 which permits free access to the setting menu. The calibration menu remains
freely accessible even when access to the setting menu is blocked by the code.
4.3 Control
The D2C can operate as a proportional controller or as a PID controller - dependent on the device version
(see identity code) and the setting.
The controlled variable is recalculated every second. Control procedures which require rapid correction of
setpoint deviations (less than approx. 30 seconds) cannot be processed with this controller. The solenoid
valve control (pulse on-time) must take account of the cycle times.
The control function (reference variable output) can be switched off through the pause function and the
water control input. The calculation of the regulated variable starts again with the cessation of the "pause"
after expiry of the adjustable delay time "td". No fault treatment is performed with active "pause" function.
4.4 Fault messages
Faults to be acknowledged are shown in the permanent displays 1, 3 and 4 by the symbol " ". The
corresponding fault messages and notes are shown in the permanent display 2. Faults/notes continuing
after acknowledgement are shown alternatively. Faults automatically remedied throught changing operating
conditions are removed from the permanent display without necessitating acknowledgement. Chapter 11
includes an overview of fault messages and causes.

NOTE
Access to the setting menus can be barred with the access code!
The number and scope of setting menus is dependent on the device version!
If the access code is selected correctly in a setting menu, then the following setting menus are also
accessible!
If within a period of 10 minutes no button is pushed, the unit automatically branches back from the
calibrating menu or a setting menu to the permanent display 1.
