The following functions, for the configuration of analogue outputs, are linked to engine
management. The outputs are managed based on an engine analogue value. Use the
"conversion curves" to adapt the single value to the output (0-100%):
•
AOF.3001
(“engine speed”).
•
AOF.3011
(“oil pressure”).
•
AOF.3013
(“oil temperature”).
•
AOF.3015
(“oil level”).
•
AOF.3023
(“coolant temperature”).
•
AOF.3025
(“coolant level”).
•
AOF.3035
(“fuel level”).
The genset implements the full management of the fuel pump, to pump the fuel from the
storage tank to the tank on the generator. For the management of the pump, HS315 must
acquire the fuel tank level on board of the generator: for this purpose, a float with contacts or
an analogue level sensor can be used (that can be selected through P.0401 parameter
“type
of sensor for fuel pump”).
Three functioning modes of the fuel pump are provided:
•
MANUAL-OFF: the pump is deactivated.
•
MANUAL-ON: the pump is activated in any case, and it is deactivated only with the
maximum level of the tank on board the generator.
•
AUTOMATIC: the pump is activated and deactivated automatically based on the
tank level on board the generator.
The functioning mode can be selected in five different ways:
•
Through the digital inputs configured through the functions:
o
DIF.2241: forces the pump in MANUAL-OFF mode.
o
DIF.2242: forces the pump in MANUAL-ON mode.
o
DIF.2243: forces the pump in AUTOMATIC mode.
If at least one of these inputs is active, the pump functioning mode is forced and
cannot be changed with the other methods described below. In case more than
one input is active simultaneously, higher priority is assigned to MANUAL-OFF,
followed by MANUAL-ON and then AUTOMATIC.
•
By changing P.0400
parameter (“fuel pump mode”).
•
“S.10” page of HS315 display is dedicated to the fuel pump. From this page it is
possible to change the pump functioning mode:
o
Use the ENTER button.
o
Use UP and DOWN keys to select the required mode.
o
Press ENTER to confirm or EXIT to abort.
Note: if no keys are pressed for 60 seconds, the modification procedure is
automatically terminated.
