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]
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.
System display
Status Icon Status information below icon
Inverter in run Symbol of pump running Frequency implemented on 3 digits
Inverter in standby Symbol of static pump SB
Inverter in fault Symbol of static pump F
Table 15: Display of SM system monitor
If the inverter is configured as reserve, the upper section of the icon representing the motor is displayed in colour, while the display
remains the same as in Table 15 with the exception that if the motor is stationary F is displayed instead of Sb.
If one or more inverters have RC without a setting, the letter A appears in place of the status information (below all icons of the
inverters present), and system start-up is disabled.
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
.
