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.
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 metering is only possible in the case of impeccable operation of the sensor. The sensor has to be calibrated / checked regularly!
NOTE A form “Documentation of controller settings type D1C” is available under www.prominent.com/documentation_D1C for the purpose of documenting the controller settings.

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 DULCOMETER® D1C controller permits settings to be made in two different menus – a “complete” and a “restricted” menu. 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 (see “General settings”). 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 if 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 - depending on the device version (see identity code) and the setting. The controlled variable is recalculated once a 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. This signal can be used, for example, for flow-proportional metering (multiplicative effect) or feedforwarddependent 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 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). 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. Faults which are rectified of their own accord due to changed operating situations are removed from the permanent display without the need for acknowledgement.

Calibration of the standard signal (zero-point calibration) The D1C sets the control output to “0” during the calibration procedure. Exception: When a basic load or a manual control variable is set the corresponding parameter is retained during calibration. The standard signals outputs mA (measured value) are frozen. The measured value frozen at the start of calibration is the proposed value. This value is adjustable (arrow buttons!). Calibration is possible only when the value is ≥2 % of the measuring range. Following successful calibration, all troubleshooting procedures relating to the measured value are restarted. IMPORTANT The measuring range of the sensor must agree with the set measuring range. The unit of measure must be set prior to calibration (see Page 14)!

This function tests whether the measured value changes from that of the sensor (at the measured value input) within the “Measured value checkout time”. It is assumed that it will do so for an intact sensor. If the measuring value does not change during this checkout time, the DULCOMETER® D1C sets the control variable to “0” and the alarm relay drops out.

Complete Operating Menu / Description IMPORTANT The timer will reset in the event of a power failure. At the end of the (timer) cycle time the DULCOMETER® D1C closes the assigned relay for the duration of “t on” (timer). “Pause” interrupts the timer. When the clock is shown in the LC display the timer can be reset to the start of the cycle at precisely this point using the enter button. The % figure in the LC display indicates the progress of the current cycle. Timer relays may be used, e.g. for shock metering or sensor cleaning. Cycle ton

The switching time of the DULCOMETER® D1C (solenoid valve) depends on the actuating variable and the “min. time” (smallest permitted operating factor of the connected device).The actuating variable determines the ratio ton/cycle and thus the switching times (see fig. above). The “min. time” influences the switching times in two situations: a) theoretical switching time < min. time: Cycle

Complete Operating Menu / Description Servomotor 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. IMPORTANT • Activation of the servomotor must be carried out with the same meticulous care as taken when calibrating a measuring sensor. • 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 %!

Remarks
Normal pause If the pause switch is off, the DULCOMETER® D1C sets the operating outputs to “0” for as long as the pause switch is off or for a set time delay td (if td is set to > 0 min). While the pause switch is off, the D1C establishes the P-proportion in the background. With PID-control (identity code characteristics “control characteristic” = 2): the I-proportion is stored when the pause is switched off (I-proportion then usually only present if Ti > 0 has been selected in the “Control setting?” setting menu). Exception: the standard signal outputs mA for the measured value or correction value are not affected by the pause. After pause is activated, the operating outputs remain at “0” for the length of the time delay td. The time delay td must be set up in such a way that in this time e.g. sample water (process-specific current concentration) flows to the sensor. With PID-control (identity code characteristics “control characteristic” = 2): The control variable output resulting from the pause and the expiry of the time delay td is reconciled jointly with the current P-component and (if Ti is set > 0) with the stored I-component. Pause hold If the pause switch is off, the DULCOMETER® D1C freezes the operating output at the most recent value for as long as the pause switch is off or for a set time delay td (if td is set to > 0 min). Whilst the pause switch is off, the D1C establishes the P-proportion in the background. With PID-control (identity code characteristics “control characteristic” = 2): Even the mA standard signal outputs for measured value or correction value are frozen. After pause is activated, the operating outputs remain frozen for the length of the time delay td. The time delay td must be set up in such a way that in this time e.g. sample water (process-specific current concentration) flows to the sensor. With PID-control (identity code characteristics “control characteristic” = 2): The control variable output resulting from the pause and the expiry of the time delay td is reconciled jointly with the current P-proportion and (if Ti is set > 0) with the newly established I-proportion. Access Code Access to the setting menu can be prevented by setting up an access code. The DULCOMETER® 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. 23 BA_DM_147_04_07_GB.p65
