SECTION 3.1

DESCRIPTION & COMPONENTS

delivered to a step-down transformer in the control

module assembly and the resultant reduced voltage is

then delivered to the circuit board. Utility 1 and 2

power is used by the circuit board as follows:

• If utility source voltage should drop below a preset

level, circuit board action will initiate automatic

cranking and startup, followed by automatic transfer

to the standby source.

• Utility source voltage is used to operate a battery

trickle charge circuit which helps to maintain battery

state of charge during non-operating periods.

TERMINALS 23 AND 194:

These terminals connect the transfer relay to the

generator circuit board. See "Transfer Relay" in

Section 3.1.

FUSE HOLDER

The fuse holder holds two (2) fuses, designated as

fuses F1 and F2. Each fuse is rated 5 amperes.

FUSES F1, F2:

These two fuses protect the terminal board UTILITY 1

and 2 circuit against overload.
