NOEC

Possible Causes

• •Connecting or disconnecting battery cables without removing fuse F3 prior
• •Controller parameters lost or reset to default settings
• •Installation of a service replacement controller requiring initial parameter setup
• •Missing engine configuration settings
• •Power to controller momentarily connected and disconnected (e.g., when connecting/disconnecting battery during installation or service)

Suggested Actions

1. 1Change the Ec parameter to the appropriate model setting (Ec13 for 14RES/RESL, Ec14 for 20RES/RESL)
2. 2Check and adjust the Uu setting if necessary (Uu01 for 60 Hz 120/240V, Uu06 for 50 Hz 115/230V)
3. 3Configure required controller parameters using RDC keypad or Kohler SiteTech software to clear NoEC fault
4. 4Do not replace the controller
5. 5For Models 14/20RES: Use RDC controller keypad or Kohler SiteTech software to set parameters
6. 6For Models 14/20RESL: Use Kohler SiteTech software to set parameters on the DC controller
7. 7Remove controller fuse F3 before disconnecting or reconnecting battery cables to prevent parameter reset
8. 8Remove fuse F3 prior to disconnecting or reconnecting battery cables
9. 9Set Engine Configuration Parameters (Ec13 for 14RES / 14RESL or Ec14 for 20RES / 20RESL models)
10. 10Set System Voltage and Frequency Parameters (Uu01 for 1 Phase, 60 Hz, 120/240 VAC or Uu06 for 1 Phase, 50 Hz, 115/230 VAC)
