Troubleshooting
1Symptoms & remedies
| Symptom | Remedy |
|---|---|
| Controller functions do not operate properly | 1. Does the genset operate correctly from the genset controls? If it does not, the problem is in the genset, not the EC 30 controller. See the genset Operator, Installation, and Service Manuals. 2. If the genset operates correctly from the genset controls, Confirm that the correct connection diagram (Figures 5, 6 and 7) was used, then check EC 30 wiring connections. 3. Confirm that the correct voltages are present on each terminal |
