D. Generator Failure
ATTENTION! Before working on the System read the section , “Safety Precautions,” on
page 15.
D.1 Tools and measuring instruments
In order to be able to manage disturbances while driving, following tools and measuring
instruments should belong to the equipment on board:
• Multimeter for voltage (AC), frequency and resistance
• Measuring instrument for inductance
• Measuring instrument for capacity
• Current absorbing clamps
• Thermometer (ideal is a infrared thermometer)
• Pressure device (pincer) für coolant circuit
D.2 Overloading the generator
Please ensure that the genset is not overloaded. Overloading occurs when the electrical load
(demand) induces a load torque in the generator which is higher than that which the diesel drive
motor can provide. Overloading causes the engine to run rough, burn oil, creates excessive
exhaust (environmentally unfriendly) and even to stall. Extra caution should be practised with
multi-power units (single and 3-phase current generation) to avoid overloading the diesel drive
engine.
The generator should only be loaded at the peak rated power for short periods only! A high peak
current is required to start many electrical devices, especially electric motors and compressors
(from a still stand state).
In order to prolong the genset´s life expectancy, the nominal electrical demand on the system
should not be more than 70% of the rated genset peak load.
Keep PEAK LOADING demand in mind when switching on electrical devices (esp. fridge com-
pressors, electric motors, battery chargers, kettles, etc.) which are fed by the generator. Careful
"powering up" (gradual loading) of the electrical demand on the generator will help prolong the life
of your genset! The genset can be run for several hours at partial load (i.e. 2/3 of rated power),
however it is not advised that it is run for more than 2-3 hours at full load. The Panda is designed
so as not to overheat even under extreme conditions. Note: The exhaust gas will become sooty
during peak-load operation.
Effects of Short Circuiting and Overloading on the Generator
The generator cannot be damaged by short circuiting or overloading. Short circuiting and over-
loading suppress the magnetic excitation of the generator, thus, no current is generated and the
voltage will collapse. This condition is immediately offset once the short-circuit has been elimina-
ted and/or the electrical overload removed.
