Starting The Engine - ESAB KHM 405 YS Manuel D'instructions

Check daily
NOTE
Do not alter the primary conditions of regulation and do not
touch the sealed parts.
ATTENTION
1. By start-up of the generator the welding circuit is
immediately operative, i.e. under voltage. Make
sure that there are no unwished electrical
contacts between the components of the outside
welding circuit (electrode, electrode holder gun,
workpiece, etc...).
2. Check that at the start-up the a.c. auxiliary
generation sockets do not feed any load.
Open the electric protection interrupter
of the generator or disconnect the plugs
of the loads from the sockets.
3. START-UP
Remember that when the machines with auto-
idle have the signal set to "auto-idle" will remain
at the minimum no. of revs (tickover) as long as
no current is drawn.
Drawing power will automatically raise the number
of engine revs to the nominal value and likewise
the tension in the alternator.
Instead, by setting the auto-idle signal to "max",
the engine revs will immediately rise to the
nominal value and likewise the tension in the
alternator.
For the machines with manual accelerator, it is
necessary to accelerate the motor manually in
order to reach the nominal tension.
Starting is actuated using the key which is an
integral part of the EP7 post on the front panel.
A) - Turn the key in a clockwise direction until all
the LED lights are illuminated.
B) - Wait until the "OIL PRESSURE" and
"BATTERY VOLTAGE"
illuminated. If the timer lamp is used, the yellow
"PREHEAT" LED comes on for the set time of
the imposed settings.
C) - As soon as the green "ENGINE RUNNING"
LED starts to flash, actuate the key switch in a
clockwise direction (momentarily in the position
then with return to rest) until obtaining starting
of the engine.

STARTING THE ENGINE

LEDs
If the motor does not start within 15 seconds, the
non starting alert will intervene: the two LEDs
"Engine running" and "glow plug" will flash
alternately (see motor protection description).
D) - At any time it is possible to stop the engine by
turning the key in an anti-clockwise direction
(OFF position).
In case of engine anomaly due to low oil
pressure,
transmission belt, low fuel level or emergency
the EP7 will automatically stop the engine.
4. The machines with auto-idle tickover at a
minimum of 2400- 2500 rpm. After starting, allow
the engine to run for a few minutes before drawing
any charge, see the related table below.
The machines with a manual accelerator tickover
at around 2000 rpm. Also in this case, respect
the warm up period in the table.
Temperature
to - 20° C from -10°C
to - 10° C from -5°C
5. start-up at low temperatures.
The motor will normally start up without problems
down to temperatures of -10° C, -15° C. In case
of starting difficulty, it is possible to repeat the
starting preheating for a max. time of 10 second,
.lightly turning the trimmer situated at the back of
the EP7 in a clockwise direction (see page M32.2
relating to engine protection "trimmer/glow plug").
For start-up and use at lower temperatures please
see the engine manual or turn to our Technical
Assistance Center.
In case of unsuccessful start-up, do not
insist for longer than 5 seconds. Wait 10 -
15 seconds before attempting another start-
up .
remain
RUNNING-IN
During the first 50 hours of operation, do not use more than
60% of the maximum output power of the unit and check the
oil level frequently, in any case please stick to the rules
given in the engine use manual.
