Instruction manual
frequency and rotation direction of the pump)
“MODE”
Moves to the next item in the following menu:
FP
Setting
of the frequency (measured in Hz); must be
≤
than the FS value.
UP Display of pressure (in bar)
C1 Display of the electro pump phase current (in A)
rt
Setting
of the direction of rotation
UF Display of flow
ZF Display of zero flow
“MODE” & “-“
The electro pump runs at the set frequency as long as the keys are held down
“MODE” & “-“ &
“+” (2 seconds)
The electro pump remains operating at the set frequency
The electro pump may be turned off by pressing “SET” (if “SET” is pressed one more time,
PWM will exit manual mode)
“SET” & “-“
Change the rotation direction of the electro pump (active only if the electro pump is
operating)
“SET”
Press it to stop the pump or to exit manual mode
Table 15: Keys usage in manual mode
Note:
In manual mode, error recovery, obtained by pressure of the
keys, is effective only on
"Bl" and "OF” error conditions.
7.1 Parameters in manual mode
7.1.1
FP: test frequency setting
The test frequency in Hz it is displayed and can be modified by pressing the “+” and “-“ keys.
The default value is Fn – 20% and values cannot exceed FS.
7.1.2
UP: Display of pressure (in bar)
7.1.3
C1: Display of the phase current of the electro pump (in A)
7.1.4
rt: setting the direction of rotation
The “rt” parameter allows to revert the pump’s rotating direction by pressing the
and
keys and
to display two possible status codes: “00” or “01”. The function is active also when the motor is running.
Note:
in manual mode, irrespective from the current menu item, it is always possible to revert the direction
of rotation by simultaneous pressure of the
and
keys for 2 seconds; this feature is available
only while the pump is running.
An arrow on the pump’s motor frame is normally used to show direction of rotation.
If you cannot check the direction of rotation of the motor you may proceed as described in sec. 5.1.2.3 or
switch to manual mode and proceed as follows:
1st method
-
Open a user, start the pump with
keys and take note of the pressure.
If a manometer is not available, press
until the pressure “UP” is displayed.
