Circuit Protection (Microprocessor Controller) - Kohler 6.5RMY Operation Manual

Circuit Protection
(microprocessor controller)
An optional line circuit breaker (sized for generator
output) is available to protect the generator from
damage because of overload or short circuits. If the
circuit breaker trips, reduce the load and switch the
breaker back to the ON position. With the breaker in the
OFF position, the generator set runs but there is no
output voltage.
NOTE
If the generator set circuit breaker trips repeatedly, see
Section 4, Troubleshooting for possible causes.
Fuses F1 (3-amp), F2 (3-amp) and F3 (15-amp) on the
controller circuit board protect the engine and controller
circuitry. (See Fuses earlier in this section.)
generator set will not crank or accessories will not work,
and the battery/connections appear okay, one of these
fuses may be blown.
Fuses V7, V8, and V9 on the AC terminal block (TB2)
protect the controller meters and lights. If the controller
lights and meters are not functioning, check the
condition of the V7, V8, and V9 fuses.
replaced and then blows again, see Section 4,
Troubleshooting for possible causes.
Voltage Regulator Fuse
A 10-amp fuse protects the voltage regulator circuitry
from damage because of overload or short circuits. If
this fuse blows, the generator set shuts down. If this
fuse is replaced and then blows again, see Section 4,
Troubleshooting for possible causes. Location of the
voltage regulator fuse is shown in Figure 2-3 for 10-18
kW, and Figure 2-4 for 6.5 kW.
