This function is particularly useful when HS315 should work with a MC100 board. In this case,
in fact, it is not possible to use the "inhibition to automatic intervention" function to prevent the
starting of the engine during the pre-ventilation phase (or others): MC100, in fact, when it
wants to start a generator, switches the related
HS315 to REMOTE START, where the
requests for "inhibition to automatic intervention" are ignored.
It is also useful if the external sequences should be performed also in MAN (because in MAN
the requests of "inhibition to automatic intervention" are ignored).
With the board in MAN, it is possible to request the starting of the engine in three ways:
•
With the START key of the panel.
o
Sequence totally manual: it is used if the bit 1 of parameter P.0495
(“keyboard
options
”) is to zero. The duration of the start attempt is established by the
operator; the attempt interrupts when the operator releases the START
button.
o
Sequence totally manual: it is used if the bit 1 of parameter P.0495 (
“keyboard
options
”) is to one. The duration of the start attempt is selected by parameter
P.0210. Only one start attempt is always done, without activation of the
anomaly “start failed”.
If the operator releases the START key when the engine has not been started yet, the
board leaves the fuel (also GAS) circuit open for 10 seconds (to check if the engine
starts): then, in case, it starts an automatic stop cycle. Starting from version 00.64, the
GAS valve is immediately closed when the START key is released (if the engine is not
started).
During the manual start, the board will automatically perform pre-lubrication, glow
plugs pre-heating and cleaning cycles. The starting is always performed with battery
#1 (if two batteries are configured).
•
With a digital input configured with DIF.2033 function ("Manual starting control"). This
input is managed exactly as the START key: same as said above.
•
It is possible to control the starting of the engine manually with a control through the
serial ports. These controls can be enabled by a digital input configured with DIF.2706
function - "Enable controls from the serial ports": if this input exists, it should be active.
To start the engine manually, it is necessary to write (within 5 seconds) the Modbus
registers in sequence:
o
HOLDING REGISTER 101: enter the password configured with the parameter
P.0004.
o
HOLDING REGISTER 102: enter the value “11”.
In response to this control, the board performs the starting as if it were in automatic.
But it performs only one start attempt, and if it fails, it does not activate A022 "failure
to start" shutdown.
Note: if the starting is requested in MAN when the engine is already running (but it was not
started by the board), HS315 acknowledges the situation: it activates all engine controls as if
it had started it, except for the starter motor, that is not activated.
With the board in MAN, it is possible to request the stopping of the engine in four ways:
•
With the STOP key on the board panel of the card.
