The LPB number on the display indicates the device in the LPB system from which the 
error or maintenance message, or special operation, was triggered. The first 2 digits 
give the segment address, the 2 digits after the dot the device address.  
Hence, 02.01 denotes segment 2, device 1. 
 
An error list is given in section “Errors“, starting on page 168.
