4.7.5. Variospeed (Option)
As a rule, the plant should not deliver power continuously. On the contrary, electric power is often
necessary urgently by inquiry similarly to the circuits of power-supplying enterprises. By using the
Variospeed mode, the rotation frequency of the engine decreases, and it increases sharply after the
receipt of an inquiry for the supply of electric power. Thus, the consumption of fuel, emission of waste
gases, noise level, and wear of the engine are essentially reduced.
A special electronic processor controls the operating mode of the plant by a measuring system and
sensors and operates the engine. Thus, even when starting the cold engine, the control system is im-
mediately turned on and does not require additional actions.
When load is connected, the control system instantly brings the engine to the rated rotation frequen-
cy and total power, which allows the connection of a consumer with high start current. By means of a
switch (pos. 16-10), the Variospeed can be disabled if required.
4.7.6. Oil automatic switch-off mechanism
The motor drive is equipped with an oil automatic switch-off mechanism. This safety feature shuts off
the engine if the oil level is too low. A restart is no longer possible. The engine can only be started after
correcting the oil level by topping up to the max. mark on the dipstick.
