ELECTRICAL SYSTEMS OPERATION (Contd)
Ether Starting System Operation.
The ether starting system is identical for all models covered in this manual and consists of the following major
components and circuitry:
BATTERY SWITCH - Provides 24-volt battery power to the protective control box through circuits 459, 81A,
PROTECTIVE CONTROL BOX - Energizes the ether feed switch through circuits 5, 5A, 27, 5C, and 570.
ETHER FEED SWITCH - Controls 24-volt power to the ether pressure switch through circuit 570.
ETHER PRESSURE SWITCH - Connects the ether feed switch to the ether tank valve through circuit 570.
ETHER TANK VALVE - Is activated through circuit 570 when the ether pressure switch is closed and the
ether feed switch is pressed.
