6.4.2

VP: Display of pressure

System pressure measured in [bar] or [psi] depending on measurement system selected.
6.4.3

C1: Display of phase current

Phase current of electric pump in [A]
A round flashing symbol may appear under the phase current C1 symbol. This signals that the pre-alarm
threshold of maximum current allowed has been exceeded. If the symbol flashes at regular intervals it means
that the motor overcurrent protection is being activated and that it will probably be triggered. In this case it is
necessary to check the correct setting of the maximum current of the RC pump, see paragraph 6.5.1 and
the electric pump connections.
6.4.4

PO: Display of the power delivered

Power delivered to the electric pump in [kW].
A round flashing symbol may appear under the measured power PO symbol. This signals that the pre-alarm
threshold of maximum power allowed has been exceeded.
6.4.5

RT: Setting the direction of rotation

If the direction of pump rotation is incorrect, it can be inverted by changing this parameter. In this menu item,
use buttons + and – to activate and display the two possible states "0" or "1". The phase sequence is shown
in the comment line on display. The function is also enabled when the motor is running.
If it is not possible to see the direction of motor rotation after entering manual mode, proceed as follows:
Start up the pump at frequency FP (pressing MODE and + or MODE + -)
o
Turn on a utility and check the pressure
o
Without changing collection, modify parameter RT and the pressure again.
o
The correct RT parameter is that which generates a higher pressure.

VF: Flow display

If the flow sensor is selected, this enables display of the flow in the selected unit of measurement. The unit of
measurement can be [l/min] or [gal/min] see section 6.5.8. In the case of operation without the flow sensor,
--
" " is displayed.

6.5 Installer menu

From the main menu, press and hold "MODE" & "SET" & "-" simultaneously until "RC" appears on display (or
use the buttons + or – in the selection menu). This menu enables the display and modification of various
configuration parameters. The MODE button enables the user to scroll through the menu pages, while
buttons + and – enable respectively to increase and decrease the value of the parameter concerned. To exit
the current menu and return to the main menu, press SET.
6.5.1

RC: Electric pump rated current setting

Rated current absorbed by a pump phase in Amperes (A). For models with single-phase power supply, the
current absorbed by the motor must be set, if powered, by a three phase 230V circuit. For models with three-
phase 400V power supply, the current absorbed by the motor must be set, if powered, by a three phase
400V circuit.
If the parameter entered is lower than the correct value, the error "OC" is displayed during operation
as soon as the set current exceeds the current set value for a set time interval.
If the parameter entered is higher than the correct value, the current sensitivity protection will trip
inadvertently over the motor safety threshold.
On initial start-up and when default settings are restored, RC is set to 0.0[A] and the correct value
must be entered; otherwise the unit will not start and the error message EC is displayed
