SETFLOAT Command
The

command can be used to set the system in floating mode.

command is correctly executed -
or “

”, when the command cannot be

”
or
“

”
respectively

SETFLOAT example:
SETFLOAT:F

When the unit operates in Floating Mode it is unable to detect earth faults
of the output conductors. Thus, a first fault can remain undetected, also
for long time. In this condition occurrence of a second earth fault can be
dangerous for equipment and goods and can, in extreme cases, also trigger
fire. Use of Floating Mode shall be reserved only for system already
equipped with an external earth fault detection system.
