UNDERSTANDING THE BBSS 
INDICATOR (BBSS) 
The BBSS is able to switch itself  off  in the event 
that a blockage or contamination prevents it from 
functioning correctly. In this instance, the BBSS will 
switch itself  back on once the blockage is cleared and 
the correct operation can be resumed.
The BBSS Indicator on the main screen is used to 
indicate the eight possible states of  the BBSS as 
follows:
In order for the trigger to be successfully operated it 
must first be released and then pulled. The Trigger 
Detection Indicator (TDI) is used to indicate each of  
the possible trigger states.
