I have a locked rotor fault on the display of a 14 kw resa generator.
Start-up went fine. First week exercised ok. Just noticed a locked rotor fault.
Unit will now start and shut down immediately. Has anyone had a similar experience?
Unit brand new with matched 200 amp ATS for unit.
Thanks

First, if you don't have the manual, try this one:
http://www.kohlerpower.com/onlinecatalog/pdf/tp6694.pdf
It has some good info and some troubleshooting procedures.
Check the controller parameters and set to a value of 3 to 5.
Locked Rotor (failed to crank). If none of the speed
sensing inputs show engine rotation within the preset
time delay of initiating engine cranking, the ignition and
crank circuits turn off for the preset period and the cycle
repeats. The fault lamp illuminates red, the alarm horn
sounds, and the unit shuts down after the second cycle
of the preset period of cranking. The local display shows
Locked Rotor Shutdown.
Could be a failed speed sensor located near the generator head end of the shaft.
If setting the controller parameters does not clear the fault and allow proper operation contact Kohler for service.
Why a 200A ATS on a 14KW unit?
Does this genset supply the whole house?
