Troubleshooting and error codes
| Trouble | Cause | Remedy |
|---|---|---|
| Overheating | Poor Contact (Contact out of adjustment) | Adjust Contacts (See Section 4.11.1) |
| Connections to Switch not of adequate current carrying capacity. | Increase the capacity of the connections by adding conductors or by replacing with heavier conductors. | |
| Contacts Burned or Pitted | Contacts should be dressed and fitted properly. (See Section 4.11.1) | |
| Bolts and Nuts of Connections not tight | Tighten all bolts and nuts. (Do not exceed torque as per Section 4.2 by more or less than 10 percent. Over-tightening bolts may cause bolts to exceed their elastic limit, leading to more loosening of the connections.) | |
| Located in too hot an ambient (40°C Max.). (Such as too close to a boiler, a furnace or the like) | Relocate in a cooler place or arrange some means of cooling. |
