ELECTRIC SUPPLY SYSTEM
Power circuit supplies electric current to each electrical part. It is composed of storage battery, gnerator,
fusible line and fuse box. Negative electrode of storage battery is earth connected and connects with
balance weight.
Even if keys switch is at ―OFF‖ position, when the general power is switched off, storage battery stil
supplies electric current to following parts, and returns back to fuse box through fusible link.
3. Input terminal of storage battery relay power supply.
4. Key switch terminal ―B‖.
5. Cabin light power supply terminal.
6. General stop electromagnet power input terminal.
7. Generator terminal ―B‖.
8. Preheat relay power input terminal.
When switch of keys is at ―ON‖ and ―START‖ position, electric current flows to fusible wire from storage
battery, reaches key switch terminal ―B‖/‖BR‖ through fuse box, and reaches storage battery relay control
terminal ―+‖ through guide line, activate storage battery relay coil and make the system power on.
When all contact terminals of storage battery are connected well, electrical device can be operated.
When generator does not work, all electrical equipments power source is supplied by storage battery.
Once diesel engine is started, power will be supplied by generator.
