GC315xx and GC400xx Technical Manual 169
Enabled in: MAN, AUTO, TEST, REMOTE START
This protection is only enabled if the engine has been started by the controller (if the command
for the fuel solenoid is activated) It is enabled the first time (from engine start) the generator's
frequency and voltages enter the tolerance range (see generator sequence description). In
MAN it is only enabled if the GCB breaker is closed. It is enabled if, under the conditions
previously mentioned, at least one of the generator voltages is continuously below the
threshold P.0301 for the time P.0302.
Type: Alarm
Category: Load/generator protection
Related parameters: P.0101 Number of generator phases
P.0102 Nominal voltage of the generator
P.0202 Generator measures hysteresis
P.0303 Maximum voltage threshold
P.0304 Maximum voltage delay
P.0328 Enables checks including on the phase voltages
To disable: P.0304=0
Enabled in: MAN, AUTO, TEST, REMOTE START
This protection is only enabled if the engine has been started by the controller (if the command
for the fuel solenoid is activated) It is enabled if, under the conditions previously mentioned, at
least one of the generator voltages exceeds continuously the threshold P.0303 for the time
P.0304.
Type: Deactivation
Category: Load protection
Related parameters: P.0105 Rated frequency
P.0305 Minimum frequency threshold
P.0306 Minimum frequency delay
To disable: P.0306=0
Enabled in: MAN, AUTO, TEST, REMOTE START
