General User Information
These operating instruction describe the technical data and function of the series DULCOMETER®D1C
controller, provide detailed safety information and are divided into clear steps. The activities to be carried
out are identified by bold bullets (•).
IMPORTANT:
Please observe the parts of these operating instructions applicable to your particular
version! This is indicated in the Section “Device Identification / Identity Code”!
IMPORTANT:
Correct measuring and dosing is only possible in the case of impeccable operation of the
probe. The probe has to be calibrated / checked regularly!

4 Functional Description
NOTE
Please refer to the description of the complete operating menu in Section 8 for a detailed
description of the individual characteristics of the D1C controller!
4.1 Operating Menu
The D1C 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 D1C 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 D1C 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 D1C 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 cycle
times must be taken into consideration when activating solenoid valves (pulse length) in the same way as
their running times when activating servomotors (3-point).
Via the control input pause, the control function (selection of controlled variable) can be switched off. The
calculation of the controlled variable starts again after cessation of "pause".
4.4 Feed Forward Control
The D1C controller can process a signal of a feed forward control. Depending on the device version (see
identity code) and the setting, this signal can be obtained in any form of a 0–20 mA or 4–20 mA signal or as
a digital contact signal with the maximum frequencies 10 Hz or 500 Hz.
During start-up, the zero point has to be checked. The multiplicative feed forward control is not designed
for switching off permanently the actuating variable (signal ≈0).
This signal can be used, for example, for flow-proportional metering (multiplicative effect) or feedforward-
dependent basic load metering (additive effect). The result of control variable calculation from the
proportional or PID control is multiplied by or added to the feedforward signal. A multiplicative feedforward
variable at the level of the set rated value carries over the calculated control variable unchanged into the
controlled variable:
Controlled variable = Feedforward variable/rated value x calculated control variable
An additive feedforward variable at the level of the rated value results in maximum controlled variable:
Controlled variable (max. 100 %) = Feedforward variable/rated value x max. controlled variable +
calculated control variable
4.5 Error Messages
Error messages and information are indicated on the bottom line in the permanent display 1. Errors to be
acknowledged (acknowledgement switches off the alarm relay) are indicated by the " ". Errors/notes
which still apply after acknowledgement are indicated alternately. During correction variable processing
(temperature for correction of pH-value), the value is indicated in the same line as the error/note. Faults
which are rectified of their own accord due to changed operating situations are removed from the
permanent display without the need for acknowledgement.

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

Calibration the Standard Signal (zero-point calibration):
During calibration, the control function persists. The standard signal of the output (measured value)
remains unchanged. The measured value registered during the start of the calibration is proposed as value;
this value is adjustable.
CAUTION:
A change of the measuring unit (see page 15) must be done before calibration!

Calibration the Standard Signal (two-point calibration)
During calibration, metering is reduced to the set basic load. The standard signal of the output (measured
value) is reduced to 0 mA or 4 mA. As value the measured value is proposed; this value is adjustable. (The
slope is indicated as deviation measured slope to norm slope).

Servomotor
Activation of the servomotor must be carried out with the same meticulous care as taken when calibrating
a measuring probe. The operating range is defined by the total resistance range of the feedback
potentiometer. The maximum limit of the range actually used is set by defining the control range.
CAUTION:
To ensure correct operation, the activation time of the actuator used should not be less
than 25 seconds for the control range from 0…100 %!

Initial value Increment Lower value Upper value Remarks
Feed forward control as per identity None Signal processing:
(Flow) code 10 Hz Signal <0.02 Hz = No flow
500 Hz Signal <0.2 Hz = No flow
Standard signal 0…20 mA Signal <0.2 mA = No flow
4–20 mA 4…20 mA Signal <4.2 mA = No flow
Feed forward control 10 Hz 0.01 Hz 0.1 Hz 10 Hz Depended on signal type.
