3.0 PROGRAMMING
3.1 MAIN FEATURES
FIG.9-USER INTERFACE
The Increase/Decrease keys allow to change the numerical values and scroll through the lists of options for
all the available menu entries.
The Enter key allows to access and exit from the various entries of the submenus. Pressing the key for 3
seconds allows, from the Initial Menu, to access the Programming Menu and to go back to the Menu one
level up from the main entries on a Menu;
The Function key allows to browse through the Menu's entries.
By pressing the key for 3 seconds from the initial page, you can access the User Menu;
TWO-COLOURED LED
The two-coloured LED displays the following conditions:
Steady green: the pump is active;
Flashing green: the pump is dosing;
Steady red: the pump is off;
Flashing red: there is an alarm;
Steady orange: if you are browsing the Programming Menu;
Flashing orange: Pump priming in progress;
The switch has three positions:
: the pump is active (ON)
O: the pump is off (OFF)
: the pump is priming (MOM)
The MOM position is monostable, therefore after setting the switch to MOM, when it is released the
switch automatically goes back to OFF.
The pump doses for 60 seconds at the maximum speed; if the MOM key is pressed again before the
60 seconds elapse, the priming is interrupted.
OPERATION
The CD model pump doses detergent according to the value of conductivity measured and the set-point value set.
Conductivity reading is carried out through the supplied electrode probe.
The flow rate of the pump depends on the difference between the programmed set-point and conductivity read.
The read conductivity value and set-point are expressed in conductivity units 0-100 (0 unit corresponds to the air
probe).
The set-point is the conductivity value that is obtained by pouring the g/l of detergent into the dishwasher tank that
is necessary for optimal washing (See 3.3.2 Set-point Set-up).
DOSING LIQUID DETERGENT (PERISTALTIC)
The speed with which the pump doses is the function of the difference between the measured conductivity and the
set-point value set, therefore, they will have the following flow rate values:

ADSP7000634 rev. 1.3 23/09/2020 12/36
Read conductivity :1% - 65% Set-point value Flow Rate Percentage = 100 * (Nominal Flow Rate/
Effective Flow Rate);
Read conductivity :65% - 90% Set-point value Flow Rate Percentage = 80 * (Nominal Flow Rate/
Effective Flow Rate);
Read conductivity :90% - 110% (hysteresis) Set-point value Flow Rate Percentage = 80 * (Nominal
Flow Rate/ Effective Flow Rate) if the conductivity value is nearing the set-point in the indicated range;
Flow Rate Percentage = 0% (non-active dose), if the conductivity value is decreasing in the indicated
range;
The Nominal Flow Rate is the flow rate indicated on the pump label, while the Effective Flow Rate value is obtained
by means of pump calibration, which enables the correction of variations on the nominal flow rate due to multiple
factors (wear of the peristaltic tube, etc).
If, from calculations on the Flow Rate Percentage value, a value greater than 100% of the pump Flow
Rate is obtained, you must consider that maximum value as equivalent to 100% of the effective flow
rate (or nominal, if pump calibration has never been executed).
DOSING SOLID DETERGENT (SOLENOID VALVE)
If the peristaltic pump is not used and the 24V solenoid valve is piloted to pass water into the solid detergent
dispenser, dosing regulation will occur at the time of opening and closing of the solenoid valve: timing is calculated
according to the conductivity distance measure by the set-point value set and the values set for the ON time (Ton)
and the OFF time (Toff).
Timing is calculated as follows:
Read conductivity: 1%-65% of Set-point E.v. ON = Ton; E.v. OFF = Toff;
Read conductivity: 65%-90% of Set-point E.v. ON = 80% Ton; E.v. OFF = Ton + Toff - 80% Ton;
Read conductivity: 90%-110% (hysteresis) of Set-point E.v. ON = 80% t.on, E.v. OFF = Ton + Toff -
80% Ton, if the conductivity value is nearing the Set-point range indicated; E.v. ON = 0 seconds (non-
active dosing) if the conductivity value is decreasing in the indicated range;
.
Fig. 10 - Operating diagram
Example:
Dosing liquid detergent
Conductivity Set-point = 10 units;
Conductivity read value = 7.2 units; (72% Set-point)
Effective Flow Rate = 4.2 l/h
Nominal Flow Rate = 4 l/h
The pump will dose 76% of the effective flow rate up to a value of 11 units, and will only start dosing again if the
measured conductivity value goes below 9 units (hysteresis around the Set-point value).
Dosing solid detergent
Conductivity Set-point = 9 units;
Conductivity read value = 6.9 units; (76% Set-point)
ON time = 20 sec;
OFF time = 10 sec;

ADSP7000634 rev. 1.3 23/09/2020 13/36
As in the previous example, the solenoid valve will remain open, thus enabling the passage of water flow until
reaching a value of 10 units (~ 110%), and will start dosing again only when the value of measured conductivity
goes below 8 units (hysteresis around the Set-point value).
The measured conductivity value of a solution is influenced by the temperature as well, and to compensate for this
influence you need to know its value. You can choose to compensate the value of conductivity automatically with
the temperature obtained from the probe PT100*integrated into the conductivity probe, or by setting the value
manually by calculating the temperature in the tank.
Conductivity variation is linked to the temperature by means of a proportional coefficient called Temperature
Coefficient; the said coefficient, which is programmed between 0.0% and 5.0%, indicates the percentage variation
of conductivity /°C. The temperature coefficient depends on the product used: should you not know the value, it is
advised to leave the default value, equivalent to 2.0%.
The dGdoser CD model pump measures conductivity to calculate the g/l of detergent dissolved in water. Since
conductivity depends on temperature, it is necessary to compensate the calculated value. The units of conductivity
shown are therefore compensated for in temperature.
MENU
When the pump is turned on, regardless of the status of the switch, the display shows the firmware version for a
second in the following way “r1.0”. It then displays the first entry of the Initial Menu.
You can browse the whole Menu both when the switch is ON and when it is OFF.
The Menu consists of the following submenus:
Initial Menu, which allows to display the status of the pump;
User Menu, which allows to change the main operating parameters;
Programming Menu,which allows to set all the operating parameters and to display statistics: this menu
can only be accessed by entering a password;
To browse through the Menus refer to Annex G - Menu Layouts.
Initial Menu
The first entry of the Initial menu displays one of the following pages, depending on the status of the switch:
H2O (no water): displayed in the event the absence of water is detected in the dishwasher tank, or a nil
conductivity value is read;
HI.C (high Conductivity Value): displayed in the event the measured conductivity value is above or within the set-
point value set (a decreasing value but which still remains in the set-point hysteresis window), therefore no dosing
of detergent in the tank is required;
Lo.C (low Conductivity Value): displayed in the event the measured conductivity value is below or within the set-
point value set (an increasing value but is still in the set-point hysteresis window), therefore dosing of detergent in
the tank is required;
(*) CD Model that has temperature reading through PT100
From the home page, with the Fkey, it is possible to scroll through the other entries of the Menu and display:
the SEt set-point value selected for conductivity;
the temperature value (°C) set manually or read by the PT100 temperature probe from 0.0 to 99.9°C: if the
automatic temperature has been set and the temperature probe is not connected, the display will show “t -
- “.
From the temperature value, always using the Fkey, you go back to the first entry, which will be preceded by the
label "St.d" (dosing status) if the switch is ON.

The t.on and t.oF entries are visible on the Settings Menu only in the case in which the pump is
programmed to pilot the solenoid valve, otherwise by C.d.t, by pressing the F key, it goes back to
the first entry of the Settings Menu.
To go back to the Programming Menu, to the InP entry, just press Enter for 3 seconds from any entry of the Menu.

4.0 ALARMS
4.1 MOTOR ALARM
The motor alarm is present in all CD pump models with motors in direct current.
In the event of excessive absorption of the motor due to malfunction, or if the power supply voltage of the pump (30
Volts) drops below 24 Volts, the pump performs three attempts to restart the motor. The three attempts carried out
before the alarm signal are respectively after 5 seconds, then 10 seconds and finally after 15 seconds from the
previous stop. The alarm is signalled as follows:
Acoustic signal through the buzzer (if installed on the pump), with a frequency of 1 second on and 1 second
off;
flashing red LED;
“not” flashing on the display;
In this alarm status the motor is stationary. Restoring normal status to the equipment is carried out by turning
off/turning on the switch or through the power supply.
4.2 MAINTENANCE ALARM
The maintenance alarm is activated when the pump has been running for longer than the time set in the relative
O.F.d sub-menu (see Settings Menu).
If you set 0.00 (h.mm) as a time value for the maintenance alarm, it will be disabled.
This is reported by the pump as follows:
Audio signal via the buzzer (if there is one on the pump) if enabled (see A.bu on the “Settings Menu”) with a
frequency of 1 second on and 1 second off;
flashing red LED;
“OFd” flashing on the display;
In this alarm status the motor is stationary. To disable the alarm, you need to go to the t.F.P entry (pump operating
time) in the Statistics Menu and reset the value.

ADSP7000634 rev. 1.3 23/09/2020 20/36
4.3 LEVEL ALARM (only for the model with the level probe)
A level probe can be connected to the pump to report the end of the product, which is indicated by the pump in the
following way:
Audio signal via the buzzer (if there is one on the pump) and if enabled (see A.bu on the “Settings Menu”)
with a frequency of 1 second on and 1 second off;
flashing red LED;
“uLo” flashing on the display;
The inlet has a 3-second recognition filter to identify false contacts and unwanted level alarm signals.
This alarm may or may not imply the pump will stop, depending on the option chosen in the “St.P” submenu
(Settings Menu: St.P=SIthe pump is stopped; St.P=nothe pump keeps on dosing).
The alarm is automatically reset when the level of the chemical product to be dosed is restored.
In priming mode, the level alarm is not indicated.
4.4 OFF STATUS ALARM
If the switch is left on the OFF position, after 20 minutes the switch alarm is activated and signalled by the pump in
the following way:
Audio signal via the buzzer (if there is one on the pump) and if enabled (see A.bu on the “Settings Menu”)
with a frequency of 1 second on and 1 second off;
flashing red LED;
“OFF” flashing on the display;
Just set the switch to ON to disable it.
4.5 OFA ALARM
The OFA alarm is a dosing alarm and is distinguished in two distinct signalling phases: OFA 1 Alarm and OFA 2
Alarm.
The OFA 1 alarm is activated when the set conductivity set-point is reached within an established time-frame
(TOFA).
The observation time may be set from 1 to 999 seconds or may be disabled (OFF) from the entry OFA of the Menu
Settings: counting of TOFA is activated at the beginning of the pump dosing.
The OFA 2 alarm is the second level of signalling of the said alarm, which is activated after a set-point situation is
not reached and remains for double the set time, therefore, after [2 x (TOFA)] seconds from the beginning of dosing.
The OFA alarm is reported by the pump in the following way:
Audio signal via the buzzer (if there is one on the pump) and if enabled (see A.bu on the “Settings Menu”)
with a frequency of 1 second on and 1 second off;
flashing red LED;
flashing “OF1” or “OF2” on the display;
OFA 1 Alarm: the pump continues to dose;
OFA 2 Alarm: Stop dosing;
The OFA 1 alarm will be disabled if:
The conductivity value is brought back to the Set-point value;
Use the switch or the pump power supply to turn it on or off;
The OFA 2 alarm will be disabled if:
Turning off and turning on is carried out through the switch or by means of the pump power supply, if the OFA
alarm Reset setting, OF.r, is equal to Aut;
Turning off and turning on is only carried out by means of the switch, if the OFA alarm Reset setting, OF.r, is
equal to OFF;
