SECTION 7 - MAINTENANCE INFORMATION
RELAY LOOK-UP TABLES - x4 VERSIONS
The PCB outline that shows the physical relay location on the daughtercard is provided in Figure 7.1
Note: Because of the high density of the BRIC daughtercards not all cards have spare relays fitted to them. Users
can acquire the 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 daughtercard is
ordered.
As an aid to fault finding, relay look-up tables are provided for Isolation and Crosspoint relays as follows:.
