2.10 Warning charge control
The warning regarding the charge control appears if the power supply from the generator
is insufficient or missing. The remaining running time of the power plant thus depends on
the remaining energy of the engine battery. If the engine battery is empty, the engine
stops because the engine control unit is no longer supplied with power.
a)
The symbol appears statically when the power plant main switch is closed and
-
the ignition is ON and
-
there is no charging voltage at the charge controller (e.g. when the engine is
not running)
In this case, the generator does not supply any energy. All electrical loads in the
circuit of the main power plant switch are then supplied only by the engine battery.
b)
The symbol disappears, with the main power plant switch closed, if the following
occurs
-
Ignition is OFF or
-
a charging voltage is present at the charge controller while the engine is
running
In this case, the battery is charged, if the generator wiring is intact and the generator
circuit breaker is closed.
c)
The symbol flashes when the ignition is switched on during undervoltage.
Warning:
If the charge control warning lights up during engine operation at speeds in the normal
operating range, this is an indication that the generator is not supplying sufficient power
to the electrical system.
Due to the high power consumption by the power plant system, only a very short engine
running time is possible, depending on the current battery charge level.
If the battery is exhausted, the engine stops!
