6 KEY TO INDIVIDUAL PARAMETERS
6.1 User
menu
The USER MENU is accessed by pressing MODE (or via the selection menu by pr 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].
If the maximum allowed current is exceeded, the current value shown on the display will start to blink between normal
display and reverse. This representation indicates a pre-alarm condition which foresees the probable tripping of the
overload protection on the motor. 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 electropump in [kW].
6.1.5 PI: Power histogram
A histogram of the power delivered is displayed on 5 vertical bars. The histogram indicates how long the pump has been
on at a given power level. On the horizontal axis are the bars at the various power levels; on the vertical axis, the time for
which the pump has been on at the specific power level (% of the time with respect to the total).
The resetting of the partial hour counter also resets the hour histogram.

6.1.6 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 18 is displayed.

Table 18: Display of SM system monitor
If the inverter is configured as a reserve, the display remains similar to Table 18 with the difference that the top part of
the icon depicting the motor appears coloured.
To reserve more space for the system display, the name of the parameter SM is not shown, but simply the
text “system” below the menu name.
6.1.7 VE: Display of version
Hardware and software version of the equipment.
