Setting a pressure (SP) that is too high for the pump performance
may cause false water lack errors BL; in these cases lower the
set pressure.
5.4 - Manual Menu
In manual operation, the sum of the input pressure and the max
-
imum pressure that can be supplied must not be greater than 8
bar.
From the main menu, hold down simultaneously the “SET” and “+” and
“-“ keys until the manual menu page appears (or use the selection menu
pr or -).
The menu allows you to view and modify various configuration param
-
eters: the MODE key allows you to scroll through the menu pages, the +
and – keys allow you respectively to increase and decrease the value of
the parameter concerned. Press SET to leave this menu and return to the
main menu.
Entering the manual menu by pressing the SET + - keys puts the machine
into forced STOP condition. This function can be used to force the machine
to stop.
In the main menu, irrespective of the parameter displayed, it is always pos
-
sible to perform the following controls:
Temporary starting of the electropump.
Pressing the MODE and + keys at the same time causes the pump to start
at speed RI and this running status remains as long as the two keys are
held down.
When the pump ON of pump OFF command is given, a communication
appears on the display.
Starting the pump
Holding down the MODE - + keys simultaneously for 2 sec. causes the
pump to start at speed RI. The running status remains until the SET key
is pressed. The next time the SET key is pressed the pump leaves the
manual menu.
When the pump ON of pump OFF command is given, a communication
appears on the display. In case of operation in this mode for more than 5’
with no flow of liquid, an alarm overheating alarm will be triggered, with the
error PH shown on the display.
Once the PH error condition is no longer present, the alarm will be reset
automatically only. The reset time is 15’; if the PH error occurs more than
6 times consecutively, the reset time increases to 1h. Once it has reset fur
-
ther to this error, the pump will remain in stop status until the user restarts
it using the “MODE” “-” “+” keys.
5.4.1 - Status:
Displays the pump status.
5.4.2 - RI: Speed setting
Sets the motor speed in rpm. Allows you to force the number of revolutions
at a predetermined value.
5.4.3 - VP: Pressure display
Plant pressure measured in [bar] or [psi] depending on the measuring sys
-
tem used.
5.4.4 - VF: Flow display
Displays the flow in the chosen unit of measure. The measuring unit may
be [l/min] o [gal/min] vedi par. 5.5.3 - MS: Measuring system.
5.4.5 - PO: Absorbed power display
Power absorbed by the electropump in [kW].
A flashing round symbol may appear under the symbol of the measured
power PO. This symbol indicates the pre-alarm for exceeding the allowed
maximum power.
5.4.6 - C1: Phase current display
Motor phase current in [A].
A flashing round symbol may appear under the symbol of the phase cur
-
rent C1. This symbol indicates the pre-alarm for exceeding the allowed
maximum current. If it flashes at regular intervals it means that the motor
overload protection is about to trip and it will very probably go into protec
-
tion status.
5.4.7 - RS: Rotation speed display
Motor rotation speed in rpm.
5.4.8 - TE: Dissipator temperature display
5.5 - Installer Menu
From the main menu, hold down simultaneously the “MODE” and “SET”
and “-“ keys until the first parameter of the installer menu appears on the
