Operating Modes; Reset To Factory Settings - Calpeda NCE GF Instrucciones Originales De Uso

ATTENTION: Make sure that, during the closure
of the terminal box cover, that the ferrite ring
does not damage the electrical board circuits
and the electronic components.
Install a device for disconnection from the
mains (switch) with a contact separation of at
least 3 mm on all poles.
No external motor protection is required.
4. Starting
ATTENTION: never run the pump dry.
Start the pump after filling the plant
completely with liquid.
Bleeding the hydraulic system.
Due to its particular structure, the pump does not
need a bleed valve.
Burn hazard. Due to high temperature of the
fluid, the pump casing and the motor may
reach temperatures higher than 50°C.
DO NOT TOUCH these parts unless with
suitable protective devices or wait and
make sure they have completely cooled.
5. Troubleshooting
If the pump is jammed due to deposits,
disconnect the electrical power and follow the
manual cleaning procedure described in the
paragraph 10.
6. Programming and operation
When the pump is connected to the network for
the first time, it operates in automatic mode.
At the subsequent starts, the pump will operate
with the last setting prior to its shut down.
To turn off the pump, press and hold the button (-)
until the display will show "Off", to turn the pump
on press the button (-) briefly.
6.1. Pushbuttons functions
(-) Through this button you can decrease
parameters, change the operating mode,
modify the parameters.
(i) Through this buttons you can confim the
selected values.
(+) Through this button you can increase
parameters, change the operating mode,
modify the parameters.
6.2. S etting c onc erni ng the
operating mode of the pump
To modify the operating mode of the pump
(except for night mode) hold the button (i) for 3
seconds, with the buttons (+) and (-) move up to
desired operating mode, confirm with (i).
After the confirmation of the operating mode the
display will show the parameter required for the
operating mode (except the automatic mode), if
necessary, change the parameter with the buttons
(+) and (-),confirm with the button (i).

6.3. Operating modes

On the pumps is possible to set 4 different
operating modes, all operating modes could work
with the night mode.
Automatic mode (factory setting):
In this mode the pump automatically sets
the operating pressure, depending on the
hydraulic system.
Proportional pressure mode:
The circulator changes the pressure
propotionally to the current flow. The
pressure set is referred to the pressure at
the maximum power, in condition of zero
flow the pressure is the 50% of the set
pressure.
In this operating mode only the pressure
value can be adjusted with the + and -
buttons.
Constant pressure mode:
The circulator maintains constant
pressure when the reference flow
changes.
In this operating mode only the pressure
value can be adjusted with the + and -
buttons.
Fixed speed mode:
The circulator works with constant curve,
in this operating mode only the speed
value can be adjusted with the + and –
buttons.

6.4. Reset to factory settings

To restore the factory settings it is necessary to
push and hold the buttons (+)(i)(-) for 5 seconds.
The pump will return in the automatic mode and
all pressure and speed parameters previously set
will be cancelled.
