Initiate an SRB restart

When SRB is suspended using the key it is possible to resume SRB operations from where they were suspended. This feature is useful when the operator has to manually operate the shearer outside of the normal cutting sequence. E.g. reverse the shearer.

1. SRB can only be ‘Restarted’ from a group of supports near the shearer, indicated by

a flashing and keys LED’s.

2. The SRB sequence can be ‘Restarted’ by pressing , then and then

WARNING

When SRB is re-started shields will commence to advance or push the conveyor where the sequence was suspended regardless of the shied operations distance from the shearer. S_Offset is not used for an SRB restart.

NOTICE

SRB can only be re-started within a time determined by the parameter S_restart from

when SRB was suspended using the key.

NOTICE

It is important to ‘Restart’ SRB and not to initiate a new start when negotiating the snake to main or snake to tail sequences of a BIDI cutting sequence. If a restart is not possible then manual operations are required until a new start can be initiated on the start of the main to tail or tail to main sequence.
