Function
When a Dry-run condition is detected for a time equal to at least the time set in

, the selected
action is executed.
The default setting is “No action”. The possible options are the triggering of an alarm (inverter stop) or
a warning signal (displayed on the keypad, but the inverter is kept running).
If an MDO for Dry-run detection is allocated to this function from the
Digital Outputs Menu
, its status
will be changed in cases 1, 2 and 3.
Option 3 is required to have only the
MDO
command without any additional signal.
