Alternator; Alternator Maintenance; Electric Installation Overload - Zetor FORTERRA HSX 120 Operator's Manual

Alternator

Charging is indicated by the red signal lamp on the united
board instrument which must be deactivated after the
start.
If the engine is running and the red signal lamp is
activated, it is a charging error. If this situation occurs,
stop the tractor and contact the service centre.
When repairing tractor by electric welding, all the conductors must be disconnected alternator.
Protect conductor '+B' against short circuit.

Alternator maintenance

When washing and cleaning the tractor protect the alternator from penetration of water or
diesel fuel! During operation the alternator must not be disconnected from the battery! The alternator
must never be put in operation without load, i.e. with the conductor disconnected from the '+B'
terminal and the '+D' terminal connected. Such a condition may induce an extremely high voltage
when the engine speed is increased, which would destroy the semiconductors! Never short-circuit
any alternator terminal during operation! The alternator must not be additionally excited. Such an
intervention would damage the semiconductors. Ensure perfect electric connection of the alternator
terminals and proper grounding of the alternator! Poles of the alternator may not be re-versed even
for a short time!

Electric installation overload

Is signalized by the selected display changing to a display
with a symbol of a battery. It is a condition when electric
installation of the tractor has such take-off, that the
alternator performance is not sufficient to accumulator
charging. If this state occurs, turn off a device or increase
engine revolutions, load of electric installation drops and
originally selected display is displayed.
The operation of tractor in the electric
installation overload mode can lead to accumulator
depletion.
