|
|
05 | Over Voltage Fault | DC Bus maximum voltage | Monitor the AC line for high line voltage or transient |
|
| exceeded. | conditions. High voltage can result from motor |
|
|
| regeneration. Buck transformer may be required. |

|
22 | Controller Reset Fault | Stop input not present. | Check stop input into control terminal board. Close door |
|
|
| and ensure any jumpers are placed correctly. |
|
|
|
|
32 | EEPROM Fault | EEProm has invalid data. | Consult the factory for further instructions. |

|
33 | Max Retries Fault | Controller failed to reset fault | Fault exists that must be corrected before further operation. |
|
| within the number of retries. | Check “Fault Buffer 1” on 1305 and 1336 for specific fault |
|
|
| that triggered max retries fault. |
