Circuit Protection (relay 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
breakers back to the ON position. With the breaker in
theOFF position, thegeneratorsetrunsbut there is no
output voltage.
NOTE
If the generator set circuit breaker trips repeatedly, see
Section 4. Troubleshooting for possible causes.
The controller circuitry is protected by a replaceable
10-ampfuse. Check thecontroller fuseif thegenerator
set will not crank and the battery and/or connections
appear correct. Replacefuse. If fuseblows again, see
Section 4. Troubleshooting for possible causes.
Voltage Regulator Fuse
A replaceable 10-amp fuse protects the voltage
regulator circuitry. The generator set shuts down if this
fuse is blown. Typically with this condition, the
generator set starts and thenshuts down in 8 seconds.
Ifthisfuseisreplacedandthenblowsagain,seeSection
4, Troubleshootingfor possiblecauses. Location of the
voltage regulator fuse for 10-18 kW is shown in Figure
2-2. See Figure 2-7 for 6.5 kW.
