From the main menu press the key ▼ until
INFO appears on the right side of the display.
Then press the key ► to enter. Select the bank
with ▲ and ▼ and then press the key ► to
enter the selected bank menu.

Manual Operation
From the main menu press the ▼ button until
MANUAL appears on the right side of the
display. Then press the ► button for 3 seconds
to enter.
Warning: in manual operation the automatic
control is not active!
In manual mode, the regulator freezes the
outputs to the current value. By pressing the
keys ▲ and ▼, a bank can be selected. The
status of the outputs is changed by pressing
the ► ( ) button. Output status is displayed. In
manual mode, the reconnect delay is not
working, but the capacitor discharge time block
is working. Leaving manual mode, the
regulator will continue to control without
disconnecting all the banks first.
Regulator safeties, in manual mode, are
disabled. It is recommended to always
return the controller to automatic mode

maintenance.
Automatic Operation
Press the key ◄ until you exit all the previous
menu.
The AUTO writing on the right side of the
display indicates that the controller algorithm is
running. When AUTO is not displayed, the
controller algorithm is not running. The reasons
for this last circumstance are: manual mode is
