Emergency If this NC contact is open, both circuit breakers
are opened and alarm A09 is triggered (the lock-
ing properties of A09 have priority).
Generator ready 1 The closed contact signals that the generator
connected to Line 1 is available for use. If this
signal is missing, alarm A12 is triggered.
Generator ready 2 The closed contact signals that the generator
connected to Line 2 is available for use. If this
signal is missing, alarm A13 is triggered.
External Line 1 control Line 1 voltage control signal received from exter-
nal device. When enabled, it indicates that the
voltage is within the limit thresholds.
External Line 2 control Line 2 voltage control signal received from exter-
nal device. When enabled, it indicates that the
voltage is within the limit thresholds.
Enable load on Line 1 Issues the enable for the connection of the load
to Line 1, in addition to the internal controls.
Enable load on Line 2 Issues the enable for the connection of the load
to Line 2, in addition to the internal controls.
Set Delay 1 Bypass to zero (Bypass Del. 1) Sets the times defined under parameters P06.07
and P06.08 to the minimum value.
Set Delay 2 Bypass to zero (Bypass Del. 2) Sets the times defined under parameters P07.07
and P07.08 to the minimum value.
Keypad lock If this contact is closed, it locks all functions from
front keypad except for display of measurements.
Lock parameters If this contact is closed, the access to the setup
Lock remote control Prevents the execution of command and write
processes over the serial interface. The reading
of data remains possible.
Start automatic test Starts the periodic test managed by an external
Battery charger alarm When input is enabled, this generates alarm A08
"External battery charger fault". The alarm is only
generated if there is mains voltage.
Alarms inhibition If enabled, this function disables the alarms that
have the property "Inhibit alarms" activated.
Alarms reset Reset of the retained alarms the triggering cause
of which no longer exists.
Command menu C(xx) Executes the command from the command menu
defined by the parameter index (xx).
