DST2600 User’s Manual 25
To start the engine in “MAN” mode, press and keep pressed the “START” key. The engine
starter is automatically released when the engine is acknowledged as running. The engine
starter is not commanded if the engine is already running.
Press the “STOP” key to stop the engine. If loads are supplied by genset, pressing “STOP”
they are changed over on mains before to stop the engine.
The automatic engine management is used in
the “AUTO”, “TEST” and “REMOTE START”
working modes (there are no differences in the engine sequence between these modes: the
differences are only in the protections and changeover management).
The engine is starter automatically if there are no blocks or disables and at least one of the
following conditions is verified:
The mains voltage is out of its tolerance thresholds and the start inhibition contact is
not activated.
The “TEST” mode is active (see par.10).
The “REMOTE START” mode is active (see par. 11.3).
In automatic mode the engine can be stopped in two ways:
a) With normal procedure. This procedure consists of doing an engine cooling cycle (only if
the load was been connected to the generator), keeping it running with no loads
connected. This procedure is applied if:
o
No more automatic start request is pending
(mains present and board in “AUTO”
mode).
o
An anomaly, qualified as “deactivation” has occurred (it is an anomaly typically
dangerous for loads but not for the genset).
b) With an emergency procedure. This procedure requires the immediate engine stop,
without engine cooling cycle. It is applied if:
o
When the “STOP/RESET” mode is selected
o
An anomaly qualified as “block” occurs. NOTE: in “AUTO” mode, if the “STOP”
key is pressed it is activated the block “07-Manual stop in automatic”.
Loads can be changed-over to generator only if all the following conditions are verified:
o
Generator voltages and frequency are in the tolerance band from a proper time.
o
The engine has been started by the board (the fuel solenoid command must be active).
o
No alarms or deactivations are present.
In the OFF/RESET mode, loads are always changed-over to mains (and so, selecting this
mode will cause an automatic changeover to mains if load was connected to generator).
