Type: Alarm
Related parameters: P.0105 Nominal frequency.
P.0133 Engine's nominal speed (primary).
P.0134 Engine's nominal speed (secondary).
P.0307 Maximum frequency threshold.
P.0308 Maximum frequency delay.
To disable: P.0308=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. 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 generator frequency (or the engine speed) exceeds continuously the threshold
P.0307 for the time P.0308.
Type: Configurable
Related parameters: P.4041 Function of the analogue input 6 (JL_4).
P.0230 Threshold for engine stopped (D+).
P.0231 Threshold for engine started (D+).
P.0357 Action on belt break.
P.0349 Belt break delay.
To disable: P.0349=0
Enabled in: MAN, AUTO, TEST, REMOTE START
Override: Engine .
This protection is only enabled if the controller is configured to use the D+ signal (P.4041 =
AIF.1300 -
“D+ Signal”) and if said signal is physically connected to the JL connector.
The protection is enabled if the engine was started from the controller (if the command for fuel
solenoid is activated) and it is disabled during the crank/stop cycles. It is activated if the D+
signal voltage is continuously below threshold P.0230 for time P.0349.
Type: Configurable (Alarm/Deactivation)
Related parameters: P.9502 Nominal current of the generator.
P.0309 Generator maximum current threshold.
P.0310 Generator maximum current delay.
P.0323 Generator maximum current action.
To disable: P.0310=0
Enabled in: MAN, AUTO, TEST, REMOTE START
Override: Generator, Full .
HS315 performs a time-dependent current protection (therefore, the higher the current
overload, the shorter the reaction time) The curve used is called EXTREMELY INVERSE with
function I
2
t. It is a generator protection as it limits the thermal accumulation of the generator
during the supply phase. As engine protection, the maximum power protection must be used,
that is independent from the load type.
A maximum current threshold and the maximum time the generator can work with this current
are defined. If the current is lower than the defined threshold, the protection does not activate.
