6. KEY TO INDIVIDUAL PARAMETERS
6.1 User menu
The USER MENU is accessed by pressing MODE (or via the selection menu by pressing + or - ). Within this
menu, again by pressing MODE, the following values are displayed consecutively.
6.1.1
FR: Display of rotation frequency
Current rotation frequency with electric pump is controlled, in [Hz].
6.1.2
VP: Display of pressure
System pressure measured in [bar] or [psi] depending on measurement system used.
6.1.3
C1: Display of phase current
Phase current of electric pump in [A]
A round flashing symbol may appear under the phase current C1symbol. 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.
6.1.4
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.
6.1.5
SM: System monitor
Displays the system status in the case of a multi-inverter installation. If there is no communication, an icon is
displayed, showing communication absent or interrupted. If there are several interconnected inverters, an
icon is shown for each. The icon bears the symbol of a pump with pump status indications below.
Depending on operating status, the item in Table 15 is displayed.
