Run Mode
When the engine starts, release the Start/Stop
switch and it will return to the center Run position.
The following control assembly functions occur:
• Voltage from the battery is replaced by output
voltage from the generator (when the engine
comes up to speed) so the control remains en-
ergized on Spec A and begin Spec B 50 Hz
only.
• Start solenoid (K1) is de-energized, opening
the circuit to the starter motor (M1) to stop
cranking. (The start disconnect is activated at
approximately 2500 rpm.)
• Fuel Pump (E2) remains energized during the
run condition. Fuel shutoff solenoid (E3) re-
mains energized on begin Spec B models.
• LPG model: Priming solenoid (K2) is de-ener-
gized.
• Field flash is no longer required and is turned
off.
• Ignition Enable remains on. Output from the
magneto assembly (G2) energizes the ignition
coil (T1) to provide spark.
• Remote run output energizes the running time
meter and the battery condition meter in the op-
tional deluxe remote control (A2).
A low oil level will cause the low oil level switch (S2)
to close. This closes a ground path to the magneto
assembly (G2) eliminating ignition spark and pre-
venting the engine from operating. If the oil level
goes below the low oil level during operation, the
genset will shut down.
Charging Circuit
A 12-volt DC output (one-ampere maximum on
Spec A or ten-ampere maximum Spec B 50 Hz)
from the generator is used to prevent discharge of
the genset starting battery during genset operation.
Spec B 60-Hz models do not have a battery charge
winding.
Stopping
Pressing the Start/Stop switch (S1) to the Stop posi-
tion de-energizes the ignition enable circuit and
grounds the magneto assembly (G2) output. This
causes the engine to stop running. The Stop posi-
tion also activates the remote stop latch feature pre-
venting restart. At the same time the fuel pump is
de-energized.
LPG models: the fuel shutoff solenoid (E2) is de-en-
ergized stopping fuel flow to the carburetor.
