heater warms the air intake piping and manifold in order to warm up the intake air during
attempted cold weather starts. To use it, toggle the momentary switch located on the
front panel. Press down on it and hold it for up to 20 seconds. It will power the glow
plug to heat it up. Release it and start your generator normally.
De Compression Lever
The de-compression leaver is often used to aid in cold starting or when starting using
the manual recoil starter. Pressing the decompression leaver causes the exhaust valve
to be held open and prevents compression during the up stroke. Eliminating the
compression cycle helps the operator create enough inertia and engine speed that
when compression is restored starting should be much easier.
Generator Voltage Regulation
The generator voltage regulation and output supply system senses the load being
drawn at the load terminals and adjusts the alternator output accordingly. The system
also monitors and adjusts generator set performance and provides power to the
electrical terminals and receptacles.
The system consists of the AC alternator, voltage regulator, ON-OFF load circuit
breaker, output load terminals, AC Volt Meter, Hour Counter, Frequency HERTZ meter
and voltage adjustment potentiometer.
The generator set output voltage is controlled by the voltage regulator. The voltage
regulator continuously senses the alternator output voltage. The voltage regulator reacts
to voltage variations by manipulating the alternator field current to maintain the output
voltage. The field current controlled by the voltage regulator is supplied by the alternator
excitation windings. The voltage regulator performs this function using three interactive
sub circuits: power input, load sensing, and DC output. The power input circuit draws
current from the AC generator exciter windings through the positive (+) field brushes at
A1 pin 3. The load sensing circuit monitors the current being drawn by the load at A1 pin
E1. As demand increases, the DC output circuit draws current from the power input
circuit, rectifies it to direct current, and reapplies it to the AC alternator (G2) field via A1
pins F+ and F-.
Starting the diesel engine automatically field flashes the AC alternator (G2) with residual
magnetism stored in the rotor. The residual magnetism induces voltage in the power
excitation windings at AC alternator (G2) pins + and 2. As the diesel engine speed
begins to increase toward its governed no load speed of 3750 rpm, the induced voltage
in the power excitation windings increases. The voltage regulator (A1) power input
circuit receives current from the power excitation windings via the positive (+) field
brushes at A1 pin 3. Whenever the voltage in the load sensing circuit matches the set
point, the current entering the voltage regulator (A1) at pin 3 is allowed to pass through
the power input circuit. Whenever the voltage entering the sensing circuit is lower than
the set point (indicating a load increase) the DC output circuit reacts by drawing current
