7.4 Starter battery
The battery is one of the most important elements of the machine. It is recommended to keep it in an efficient condition to increase
its useful life, to avoid faults and to reduce the management costs of the machine.
The starter battery is for:
Powering the machine control circuits.
Starting the heat motor.
7.4.1 Starter battery maintenance
The starter battery does not require any special maintenance:
Keep terminals clean by removing any oxidation residues.
Check correct terminal tightening.
7.4.2 Starter battery recharge
Starter batteries do not require any recharge.
During normal operation of the Diesel engine an alternator recharges the battery (machines “RTD”, “RTED”). On those machines
equipped with a 380V three-phase electric pump, the electric pump control system keeps the starter battery charged. On machines
with battery a DC-DC converter keeps the starter battery charged.
