The generator
The symbol of the generator is empty if the generator is idle,
flashing with g
enerator running but not supplying and it is shown “in reverse” (that is,
full) when the generator is in supply conditions (see par. 9.3). Under it, the medium
value of the three Generator unchained voltages and the Generator frequency
measured by the device are shown.
The loads
The symbol of
the load is displayed in “reverse” if the loads are
powered from the mains or from the generator.
The circuit breakers
GCB
and
MCB
. The symbol of the circuit breaker shows:
o
The open/closed status.
o
The difference between status and the breaker command (in this case the two
contact points of the breaker flash).
The power flows, displayed with arrows in the three branches of the system. The arrow
points in the direction of the power. The arrow flashes (to indicate a faulty situation) in
case of reversed power on the generator and in case of negative power to the loads.
The active power measure and that of the power factor.

M.02 MAINS
INFORMATION!
The page is displayed only with SSB systems (see par. 0)
In fact, every digital input can have an AND/OR logic associated, which determines its
status
This page shows the Phase-to-Phase concatenated voltages and the frequency of the
generator, in addition to the rotation direction of the phases (clockwise or counter clockwise).
For three-phase systems, the phase-to-phase voltages are displayed; for the one-phase
systems, the phase-to-neutral voltage and the voltage between neutral and negative battery
are displayed and the rotation direction is not displayed.
To the bottom right there is an icon that allows immediate identification of the fact that the page
is related to the MAINS measures.
7.4.7.3
M.03 MAINS
INFORMATION!
The page is displayed only with SSB systems (see par. 0) In fact,
every digital input can have an AND/OR logic associated, which determines its status.
This page is only shown for the three-phase systems and only if the system is configured to
use the neutral connection (see par. 5.9.1In fact, every digital input can have an AND/OR logic
associated, which determines its status . The three phase-neutral voltages are shown and the
negative of the battery, in addition to the rotation direction of the phases (clockwise or counter
clockwise).
To the bottom right there is an icon that allows immediate identification of the fact that the page
is related to the MAINS measures.

M.04 GENERATOR
This page shows the Phase-to-Phase concatenated voltages and the frequency of the
generator, in addition to the rotation direction of the phases (clockwise or counter clockwise).
