2 PROGRAMMING
The MINI-PRO DD peristaltic pump can be installed on dishwashers with 1 or 2 solenoid valves.
2.1 PROGRAMMING FOR INSTALLATION ON DISHWASHERS WITH 2 SOLENOID VALVES
To install on dishwashers with 2 solenoid valves, connect both cables and then set the CHARGE and RINSE signal
parameters. The T wait time (item 5 in the menu) must be set to zero. The following may be set for both signals:
a)
dosing time
b) rotor speed
If one or both dosing times are set at zero, this means they are disabled and the pump doses in volumetric mode at the
programmed speed as long as the signal is present.

If both signals are present, priority is given to the CHARGE signal.
2.1.1 Operation with 2 solenoid valves
CHARGE SIGNAL
When the CHARGE signal is active, the pump doses for the T Charge time at the V Charge speed.
To set these 2 parameters, with the pump in Standby mode, push and hold the PROG key down for at least 4 seconds.
The V Charge and T Charge parameters may be set on items 1 and 3 of the programming menu, represented as numbers
1 and 3 on the red display. The menu can be scrolled using the UP key
As soon as the item with the value that must be modified is shown, press the PROG key. The value will begin to blink,
starting with the first digit at the left. Press the UP key
again to modify the blinking digit. When the parameter has been set correctly, push and hold the PROG key down until the
display stops blinking. Other items of the menu can now be scrolled.
RINSE SIGNAL
When the RINSE signal is active, the pump doses for the T Rinse time at the V Rinse speed.
To set these 2 parameters, with the pump in Standby mode, push and hold the PROG key down for at least 4 seconds.
The V Rinse and T Rinse parameters may be set on items 2 and 4 of the programming menu, represented as numbers 2
and 4 on the green display (the first on the left). The menu can be scrolled using the UP key
As soon as the item with the value that must be modified is shown, press the PROG key. The value will begin to blink,
starting with the first digit at the left. Press the UP key
again to modify the blinking digit. When the parameter has been set correctly, push and hold the PROG key down until the
display stops blinking. Other items of the menu can now be scrolled.
2.2 PROGRAMMING FOR INSTALLATION ON DISHWASHERS WITH 1 SOLENOID VALVE
To install on dishwashers with 1 solenoid valve, connect only the RINSE cable, set the T wait time higher than zero and
then set the RINSE signal parameters. The following may be set:
a)
dosing time
b) rotor speed
c) T wait time
If the dosing time is set at zero, it is disabled and the pump doses in volumetric mode at the programmed speed as long as
the signal is present.
