3.2 Start screen / Overview
Short after the ENS2 unit has been connected to mains or while it is running and any button has been pushed to
activatethedisplay,itwillshowthe“Overview”screen.Thisscreencanalsobeaccessedfromthemainmenu:
Therstrowshowsthenameofthestandardwhichiscurrentlyactiveforsupervision.Incaseofoneormultiple
supervisionparametersdi󰀨erfromthestandard,itwilladditionallyshow“Adj.”toindicatethemodication.
The next rows show actual values from the supervision, such as the voltage of the single phases (L1, L2, L3),
plusthephase-to-phasevoltage(L12,L23,L31)andthefrequency(f).Thevoltagevaluesaredenedthisway:
L1: Voltage between phase 1 and N
L2: Voltage between phase 2 and N
L3: Voltage between phase 3 and N
L12: Voltage between phase 1 and phase 2
L23: Voltage between phase 2 and phase 3
L31: Voltage between phase 3 and phase 1
The last row shows the status, which can also contain the last occurred error. See section „3.3. The status row“
for details. On the right-hand side there is a small menu that shows the current assignment of the three pushbut-
tons. Pushing the top button manually triggers a relay test. Details about this function can be found in „3.4. Relay
triggering test“. The middle button is used to access the main menu (see „4. Main menu“).
Thelittle“i”,whichisassignedtothelowerbutton,isusuallyusedtoaccessstatusinformation.Incaseitisblinking,
an error has occurred, which has caused the supervision circuit to act the internal relays and thus the contactors.
Pushing the button then takes you to an error display of the last 12 errors. This error overview can also be accessed
from the main menu. Error messages are explained in „4.2. Error messages“. Accessing the error overview also
acknowledgestheblinkingofthe“i”.
