Configure the analogue output (parameter P.6001 for output 1) with function
AOF.1003 ("Speed regulator (generic)"). In this case, the output scaling can
be done by means of a conversion curve.
Speed governor connection via CANBUS
Normally, HS315 makes the internal speed request (0-100%) correspond to a real speed
range of +/- 120 rpm, with respect to the rated speed. This is the default condition, configured
with P.0713=1380 and with P.0714=1620.
Note : even if the nominal speed of the engine is not 1500, the two previous values force an
offset of +/- 120 rpm with respect to the nominal speed: an internal speed request equal to 0%
is translated into a value of -120 rpm, an internal request equal to 100% is translated into a
value of +120 rpm.
The two parameters P.0713 and P.0714 can be modified as required (however, be careful to
configure them correctly with respect to the rated speed). For example, if you want a speed
range between 1200 and 1600 rpm set P.0713=1200 and P.0714=1600: an internal speed
request equal to 0% will be translated into a speed of 1200 rpm, an internal request equal at
100% it will be translated in a speed of 1600 rpm.
Often, the GCB circuit breaker is for protection only, thus it is always closed. In this case, when
the engine starts, the generator DC voltage could be higher or lower than the common bus
voltage, but the controller cannot do anything to avoid that (it can only quickly regulate the
current).
Instead, if HS315 has the opening/closure commands for GCB, it starts the engine with GCB
opened and, before closing it, HS315 matches the generator voltage to the common bus
voltage. GCB closure is allowed when the voltage difference between generator and common
bar is lower than P.9667
(“Voltage match window”) or, in any case, after the maximum time
set by P.9668
(“Maximum duration for voltage matching”).
To disable this stage, set P.9668 a 0.
The voltage control loop is the same of the FLOAT and ABSORBTION stages, except it works
on the generator voltage instead of on the battery voltage.
Often, the GCB circuit breaker is for protection only, thus it is always closed. In this case, the
cooling cycle for the engine must performed with GCB closed. During this stage, the controller
regulates the generator current to zero.
The current control loop is the same of the BULK stage, except it works on the generator
current instead of on the battery current.
The controller records any change in the charge cycle in the events log, if it is enabled with bit
8 of the P.0441 parameter:
•
EVT.1500: charge status: idle.
•
EVT.1501: charge status: voltage matching.
•
EVT.1502: charge status: BULK.
•
EVT.1503: charge status: ABSORBTION.
•
EVT.1504: charge status: FLOAT.
•
EVT.1505: charge status: FLOAT ended.
•
EVT.1506: charge status: cooling down in progress.
