To disable: P.0302=0
Enabled in: * MAN, AUTO, TEST, REMOTE START
Override: Generator, Full .
This protection, when possible, works on the DC voltage of the generator. If not possible (GCB
closed), if AC voltages are available it works with them,
otherwise it will never be activated .
It is only enabled if the engine has been started by the controller (if the command for the fuel
solenoid is activated) and it is disabled during the crank/stop cycles. It is enabled the first time
(from engine start) the generator's voltages and frequency/speed enter the tolerance range
(see generator sequence description). It is activated if, under the conditions previously
mentioned, the DC voltage of the generator or at least one of the AC voltages is continuously
below the threshold P.0301 for the time P.0302.
In MAN it is only enabled if the GCB breaker is closed, or if the bit 2 of the parameter P.0249
is set to
“1”.
Type: Alarm
Related parameters: P.0102 Nominal voltage (AC) of the generator.
P.9641 Nominal voltage (DC).
P.0202 Hysteresis for generator's measures.
P.0303 Maximum voltage threshold.
P.0304 Maximum voltage delay.
To disable: P.0304=0
Enabled in: MAN, AUTO, TEST, REMOTE START
Override: Generator, Full .
This protection, when possible, works on the DC voltage of the generator. If not possible (GCB
closed), if AC voltages are available it works with them,
otherwise it will never be activated.
The protection is only enabled if the engine has been started by the controller (if the command
for the fuel solenoid is activated) and it is disabled during the crank/stop cycles. It is activated
if, under the conditions previously mentioned, the DC voltage of the generator or at least one
of the AC voltages exceeds continuously the threshold P.0303 for the time P.0304.
Type: Deactivation
Related parameters: P.0105 Nominal frequency.
P.0133 Engine's nominal speed (primary).
P.0134 Engine's nominal speed (secondary).
P.0305 Minimum frequency threshold.
P.0306 Minimum frequency delay.
To disable: P.0306=0
Enabled in: * MAN, AUTO, TEST, REMOTE START
Override: Generator, Full .
This protection works on the generator frequency if the AC voltages have been connected,
Otherwise, if possible, it works on the engine speed. It is only enabled if the engine has been
started by the controller (if the command for the fuel solenoid is activated) and it is disabled
during the crank/stop cycles. It is enabled the first time (from engine start) the generator's
voltages and frequency/speed enter the tolerance range (see generator sequence
description). In MAN it is only enabled if the GCB breaker is closed. It is activated if, under the
conditions previously mentioned, the generator frequency (or the engine speed) is
continuously below the threshold P.0305 for the time P.0306.
In MAN it is only enabled if the GCB breaker is closed, or if the bit 2 of the parameter P.0249
is set to
“1”.
