DST2600 User’s Manual 11
In details:
a)
“OFF_RESET”
: in this mode the board is switched on but all the genset control and
management functions are excluded. This is the mode to use when the automatic genset
starting is not required (for instance, to avoid automatic starting, useless during a factory
closing time, etc.) and above all as security position for genset maintenance. When the
“OFF_RESET” mode is selected the genset cannot start if mains fails. The mains switch
is forced at work and so loads are supplied from mains (if mains is present). In any case
the surveillance on mains, generator and engine status, and the display visualizations are
active. When the “OFF_RESET” status is selected, the following operations are carried
out:
1) The loads changeover is forced to mains (if loads were supplied from
generator).
2) The engine shutdown sequence is activated (if the engine was running).
3) Reset of all the eventual memorized anomalies that caused the genset
shutdown.
In this mode the battery charger is in any case active
In “OFF_RESET” mode (and only in this mode) it is possible to visualize and change the
device programmable parameters.
b)
“MAN” (MANUAL):
in this mode the board is ready to manage a manual use of the
genset. In brief:
1)
The manual start and stop procedure are enabled, where the automatic
procedure are disabled (so the engine won’t never start automatically by the
board).
2)
It is possible to changeover the loads on generator with the explicit command
of the operator (only if the generator is in the proper condition to supply). The
changeover won’t never be done by the board (except the changeover to
mains if a block or a deactivation arises)
No action upon engine and changeover will be made when passing from “AUTO” to “MAN”:
the engine maintains its status (running/stopped) and loads too (on mains/on generator).
It is only stopped the eventual start attempt in progress.
c)
AUTO (AUTOMATIC)
: this is the normal working mode of the board. In this mode the
engine is started/stopped automatically when mains fails or with regular intervals to keep
the genset efficient. In the same way loads are automatically changed over on mains or
generator,
according
to
the
conditions
of
both
of
them.
REMARKS: when the AUTO mode is selected, it is forbidden every kind of
maintenance on genset.
In this mode is furthermore possible to run a manual “TEST”, besides the automatic
periodical running test (see par. 10).
Moreover, it is possible to pass to “REMOTE START”
mode, by a digital input command or by a serial port command.
