6 Check that the stop lever is in work position,
open the
starting air valve, shut the blow-off valve when there is no
more condensate.
7 Push the start button until the engine starts firing. If the
engine does not start after 2 - 3 seconds the reason should be
checked.
8 On engines equipped with pneumatic starting motors,
never make a second starting attempt before the flywheel has
stopped.
9 Check immediately after start that the pressure and
temperature values are normal.
10 Check that the automatic alarm and stop devices are
set in work position.
03.1.2 Remote and automatic start
If the engine has been out of operation for more than a week the
first start is to be carried out manually according to point 1.
Engines with automatic starting must be tested once a week.
1 When starting the engine remotely, start the lubricating
oil priming pump at first. Usually, the operation of the pump
is indicated by a signal lamp. The engine can be started when
the lube oil pressure gauge shows an oil pressure of about
0.5 bar.
In automatically starting engines the priming pump operates
continuously thus keeping the engine ready for start. At least
every second day, make sure that the pump is running.
2 Press the remote start button of the remotely controlled
engine. The solenoid valve located on the engine will then be
energized and allow starting air to the engine. Press the start
button long enough (1 - 2 s.) to make the engine start. The start
will be indicated by the remote tachometer or by a signal lamp
showing when the engine is running. In some cases the remote
control is automated so that, when pressing the button, the
priming pump starts and after an increase of the oil pressure
(to about 0.5 bar) the engine starts automatically as described
in point 3.
3 In engines with automatic starting the solenoid valve is
controlled by a program relay. The normal program is as
follows: As soon as the program relay gets a starting impulse
the solenoid valve is energized for 2 - 4 seconds and opens, then
starting the engine.
If the engine fails to start, a new starting attempt takes place
after 20 seconds, whereby the solenoid valve will be energized for
