SECTION 7 - MAINTENANCE INFORMATION
RELAY LOOK-UP TABLES
This section provides a cross reference between the matrix crosspoints and the corresponding relays on the matrix
daughter cards. A PCB layout diagram is provided in Figures 7.1 to enable the location of relays and assist in fault
finding.
Note: The matrix cards in this range have spare relays fitted to them. Users can also acquire replacement relays
either from the OEM or from Pickering Interfaces.
Replacement of relays should only be carried out by qualified personnel using the correct equipment.
If qualified personnel are not available, or the location of a defective relay cannot be positively determined
it is recommended that the module is returned to Pickering Interfaces or a replacement daughter card is
ordered.
