OPERATION

4 OPERATION
4.1

GENERAL

The genverter is operational after full installation and filling up
with fuel, engine lubricating oil and cooling liquid, connecting
the battery and connecting the digital remote control panel.
4.2

PROGRAMMABLE SPEED

At the time of commissioning, the engine rpm are set to meet
the output requirements of the installation.

OPERATING INSTRUCTIONS

4.3.1

Daily check of oil level

Be sure to keep the oil level between upper and lower limits of
the oil gauge. Too much oil may cause a drop in output or
excessive blow-by gas, while too little oil may seize the engine's
rotating and sliding parts.
Procedure:
1 Check the engine oil level before starting or more than 5
minutes after stopping the engine.
2 Remove the oil dipstick, wipe it clean and reinsert it.
Take the dipstick out again, check the oil level gauge and
reinsert the dipstick.

3 If the oil level is too low, remove the oil filler plug, and add
new oil to the prescribed level.
4 After adding oil, allow the oil to come down to the oil pan
before checking the oil level again.

Summarized operating instructions (daily use)

Routine "pre-start" checks:
1 Check oil level and cooling liquid level.
2 For systems incorporating PMG: power source selector
switch (off/shore power/generator power) in "off"
position, or switch of all consumers in the usual way. If a
Whisper Switch of Transfer System Switch is installed, this
operates automatically.
3 Switch on battery switch (if installed).
4 Fuel valve: open.
16
Starting:
Push the start button and hold for a second to initiate the fully
automatic starting procedure.
In operation checks:
1 Check for abnormal noise or vibration
2 Check the output parameters on the remote control
display
3 For systems incorporating PMG: switch power source
selector to "generator" position. If a Whisper Switch of
Transfer System Switch is installed, this operates
automatically.
4 Before loading the generating set up to its maximum, have
it run warm. Continuous load should be restricted to 70 %
of maximum load.
Stopping the genverter:
1 If the genverter has been running under full load for a
longer period, do not shut it down abruptly. Reduce the
electrical load to about 30% of the rated load and let it run
for around 5 min.
2 Press the STOP button.
3 Switch to another AC power source, if available

Extended operating instructions

Check when starting the first time or after a longer period of
rest:
1 If there is any damage caused by transport or installation.
2 Check if the installation conforms to the installation
instructions.
3 Ensure the engine is free to turn without obstruction.
4 Check all hoses and hose connections for leaks.
5 Check all cables and terminal connections.
Routine "pre-start" checks:
1 Check engine oil level. The genverter switches off in the
event of insufficient oil pressure. Even when the oil level is
too low, the oil pressure can be high enough not to trip an
alarm. Do not run the engine with the oil below the lowest
mark, because a smaller volume of oil will become
contaminated considerably quicker than a larger volume.
Moreover, a low level may affect cooling. Therefore, we
recommend daily oil-checks. Check oil level prior to
starting the engine or at least 5 minutes after the engine
has stopped.
2 Check for leakages.
3 Switch off all devices.
4 Switch on the battery switch (when installed).
Starting the genverter:
By pushing the start button and holding it for a second, the
electric system is activated. You can monitor the
procedure on the display of the remote control panel.
First, the fuel pump will prime the fuel for a few seconds
