Function Description Notes
OFF
OFF Input not used
For
Forced changeover on secondary line
When closed, it forces the changeover on the
secondary line even if main line voltage is within
the limits. Re-commutation occurs on the main
line when the input is released or in case the
secondary line voltage is not within the limits
IN.R
Inhibition return on main line
In automatic mode, when closed, it blocks
the automatic return on the main line after the
main line voltage has returned within the limits.
It is used for preventing the second power
cutoff, due to the re-transferal, from occurring
automatically in an unexpected moment
S.GE
Generator voluntary Start/stop
In automatic mode, when closed, it starts up
the generator
EME
Emergency
NC contact which, if opened, opens both circuit
breakers and generates an alarm
G.rE
Generator ready
If closed, it refers to a Generator in automatic
mode and not in alarm mode.
If opened, it generates an alarm code
Loc
Keyboard total lock
If closed, it locks all keyboard functions except
for measurement views
L.PA
Lock parameter access If closed, it locks the access to setups
