The operation mode is displayed by means of a LED indicator at the front side of the housing.

It is equipped with extensive safety measures to ensure that it switches off immediately as soon as the AC plug is removed from the wall socket or the public grid fails in operation.

The inverter can be connected to a PC through RS232 communication to display some parameters such as voltage and current inputs, mains voltage and frequency, maximum AC power, Kwh, etc.

EESFC/FSS is a software application in which the instructor can define a faults sequence during the execution of the unit. The student, when executing the software, should identify this sequence.

Faults mode Access Screen

Once accessing, we have two possibilities: configure the faultssequence ("configure" button) or reset the previous sequence("reset" button).

Faults mode Main Screen

Faults Sequence Configuration

The software will ask for the first, second...until the sixth fault. To select the fault we will use the red ring called "faults". In this option, we will be able to repeat faults, that is to say,the same fault will be able to be included the times we want.

When selecting the faults the order of the sequence can be seen in the“Faults order" indicator, as shown in this image.
