BACKILLUM Command
| Format: | BACKILLUM state
state = (ON | OFF | NULL) |
| Description: | Turns the guide fibre backillumination to state ON or OFF.
NULL gives back status.
Warning Ensure that the Westinghouse tv is not powered up or serious damage will result. Autofib assumes that the guide fibre illumination state is the same as the spectroscopic fibres backillumination state. Therefore if the guide fibres are not backilluminated but the spectroscopic fibres are backilluminated then the control system will not allow the movement of any fibre as the software will check that the backillumination (i.e. guide fibre backillumination) is ON. Conversely if the guide fibre backillumination is on but the spectroscopic fibre backillumination has failed then the control system is unable to prevent attempted movement of a fibre. |
| Example: | Engineering command > backillum ON |
For further information refer to the `AF2 Control System Software Manual'.
