(settable); the starter will then crank the engine until it
starts. While starting the alarms are blocked (this is
achieved by pushing the Start/Stop button). The alarms are
reactivated after 10 seconds.
Warm up the engine without load for 3 minutes. A restart
protection prevents cranking the engine when it is already
running, which could cause damage.
Never use ether or gasoline to facilitate a cold
start as it could damage the engine.
Checks once the engine is in operation:
1 Check for abnormal noise or vibration.
2 Check the output parameters on the remote control
display.
3 Observe the exhaust at the rated load.
The exhaust must be free from soot. Do not allow the
engine to run with visible smoke from the exhaust without
investigating the cause, as this may result in an expensive
breakdown.
Engine load during longer operation:
During the first 50 hours of running, the continuous load
should be restricted to 70 % of the maximum load.
Running at no load or light load for long periods in the first
50 hours may cause cylinder glazing and high oil
consumption.
Avoid overloading the genverter. Overloading occurs when
the electrical load (demand) is so high that by the diesel
engine has trouble driving the alternator. It causes the
engine to run rough, while using oil and excessive fuel and
producing soot. The engine may even stop. The genverter
should therefore be loaded at the maximum rated power
for short periods (2-3 hours) only! The high peak current is
meant for the ability to start electrical devices that need a
high current for starting especially electric motors and
compressors (from a still stand state).

In order to prolong the genverter's life expectancy, the
nominal electrical demand of the system should not
exceed 70% or the genverter's rated maximum load.
Please note this when switching on your electrical
equipment! Nevertheless, the genverter is designed so as
not to overheat, even under extreme conditions.
Do not run the genverter for very long periods at no load
or at very low load. When this is necessary, increase the
load to at least 70% for one hour in 10 hours. Long term
running at too low load will cause the exhaust to be
choked by carbon (soot).
Neither remove the battery while the engine is
running nor remove any electrical cable while the
battery is connected to the circuit. Only
disconnect the battery with the engine stopped
and all switches in "OFF" position.
Stopping the genverter:
1 Avoid stopping the genverter abruptly after a long period
of operation at high load. Prior to switching off the
genverter, decrease the load (i.e. turn off most electrical
consumers) and let the genverter run at low load for
approx. 5 minutes to allow the engine to cool down
sufficiently. Another reason to switch off electrical
consumers prior to stopping the genverter is the voltage
drop that occurs as the engine comes to a halt.
If the genverter is operating in a hot environment and is
not allowed to cool down, excessive heat in the engine
may trip the "high temperature" alarms. This will prevent
restarting of the engine for some time.
2 Press the STOP button.
3 Switch to another 230V power source, if available.
If the engine is not running and the 'failure' and
'charging' LEDs are blinking, press the stop
button in order to prevent the starter battery
from being drained.
