| | 3 | ### bias disconnection |
| | 4 | |
| | 5 | __Symptom__ |
| | 6 | |
| | 7 | - biasctrl is in state DISCONNECTED |
| | 8 | |
| | 9 | __Solution__ |
| | 10 | |
| | 11 | - Do _RECONNECT_ |
| | 12 | - Send a command like _REQUEST_STATUS_ |
| | 13 | - Sometime the bias crate will disconnect again, do _RECONNECT_ |
| | 14 | |
| | 15 | __Not Helping__ |
| | 16 | |
| | 17 | - do not close or kill biasctrl |
| | 18 | |
| | 19 | ### OverCurrentStatus |
| | 20 | |
| | 21 | __Symptom__ |
| | 22 | |
| | 23 | - when biasctrl ramped the voltage, it get in the state OVERCURRENT |
| | 24 | |
| | 25 | __Solution__ |
| | 26 | |
| | 27 | - First try biasctrl/RESET_OVER_CURRENT_STATUS (maybe a few times) |
| | 28 | - if it don't help try to ramp the voltage down |
| | 29 | - biasctrl/SET_GLOBAL_DAC 0 |
| | 30 | |
| | 31 | __Not Helping__ |
| | 32 | |
| | 33 | - do not close or kill biasctrl |
| | 34 | |
| | 35 | ### Status notReferenced |
| | 36 | |
| | 37 | __Symptom__ |
| | 38 | |
| | 39 | - biasctrl is in state notReferenced |
| | 40 | |
| | 41 | __Solution__ |
| | 42 | |
| | 43 | - start the Ramping again |
| | 44 | - biasctrl/START |
| | 45 | |
| | 46 | __Not Helping__ |
| | 47 | |
| | 48 | - do not close or kill biasctrl |
