storage tank. The pump is stopped until W064 early warning is activated: when the
operator “cancels” it, the pump restarts with another cycle.
•
HS315 allows configuring the electric source that must supply the pump, through
P.0406
parameter (“Supplying of the fuel pump”):
o
0: generator voltage.
o
4: from an always present voltage.
If HS315 detects that there isn't voltage on the selected source uninterruptedly for
five seconds, it will stop the pump (set P.0406
on “4” to disable this control).
•
The pump is disabled in OFF/RESET, but only if this mode persists consecutively for
five seconds.
The board will record the following events, if the fuel pump status changes (if enabled with the
bit 7 of P.0441 parameter):
•
EVT.1070: the pump is started.
•
EVT.1071: the pump is stopped.
The controller manages three different maintenance counters.
The first and the second are identical:
•
The first can be configured by means P.0424 and P.0425, activates the warning
W039.
•
The second can be configured by means P.0436 and P.0437, activates the warning
W040.
The following description is for the first counter, the second is the same. The board can
automatically communicate to the operator the request to carry out engine periodic
maintenance. This function is configurable with parameters P.0424 and P.0425. With P.0424,
it is possible to set extra operation hours for maintenance service. In P.0425, on the contrary,
the type of anomaly to be activated at the end of the period is configured:
•
1: warning (W039).
•
2: Latched warning (K039).
•
4: deactivation (D039).
•
8: shutdown (A039).
The function is enabled if the parameter P.0424 contains a value other than zero. The count
starts in the moment this parameter is set. When the configured (working) hours have elapsed,
the board records, on its non-volatile memory, the maintenance request. In this way, also
cutting off the supply to the board, the piece of information doesn't get lost and, above all, the
anomaly cannot be cancelled. If an alarm has been selected withy P.0425, then the generator
cannot be used again. This function allows to manage rental contracts “by hour number”.
To cancel the maintenance request (and the relevant signal) requires setting again the
parameter P.0424: to disable the function, set the parameter to zero; to set the next
maintenance after the same period as the previous one, simply confirm the existing parameter;
or set a new interval. To modify these parameters requires installer level password.
The third counter can be configured by means parameter P.0438, that allows to select the
number of days to the next maintenance request. You can use the previous description for this
counter too, except it activates always a warning (W050).
