This is not an error, and indicates a that a command has been accepted, is being action and that the mechanism is moving, this value may be or'd with other command errors.
Command accepted, task active ( error code 80 )
This is not an error, and indicates a that a command has been accepted and is being action, this value may be or'd with other command errors.
01 - Mechanism is busy
If a command had already been accepted and another was sent for the same mechanism then a mechanism error 01 is given, allow the previous command to complete before sending another, the active command is not affected.
02 - Command rejected - Out of range
A parameter sent was out of range, each mechanism has an operational range which has been exceeded, no action is taken.
03 - Command rejected - Invalid parameter
To many or too few parameters were given, no action is taken.
04 - Command rejected - Invalid format
05 - Command rejected - Monitor mode list full
The list of monitors which will receive status commands is full, usually this is only the system computer, reset the 4MS if necessary to ensure that no monitors a left on the list inadvertently.
06 - Command rejected - Invalid function
Each mechanism has valid functions, e.g. a move command cannot be issued to the DOR mechanism, if the function is not allowed then this error is given and no action is taken.
07 - Filter wheel is interlocked - access cover open
The MFW cannot be moved because the access cover is open,
08 - Command has been cancelled
The network cancel command was used on the mechanism.
09 - Node-name not entered on Monitor mode list
The following pages list the mechanism errors. Each error is listed in numerical order on at least a single page. A description of what the error is indicating is given and probable causes and possible corrective actions are listed. Space is left for other findings to be included against each error code, it is therefore important to use the copy of this document kept in the WHT control room, as the fault may have been seen before, if you do make any findings during fault diagnosis that you consider may be of value, please included them in the space provided for future reference, please include extra pages if necessary.
