TROUBLESHOOTING THE MINI LINK

5. The ICN is appropriately terminated as described in IB-23A160.

6. If using a base configuration of the Mini Link/EXT (supporting 1 ICN) the two-wire

interface is connected to the Mini Link/EXT terminal block labeled ICN0.

7. If using a fully-configured Mini Link/EXT (supporting 2 ICNs) the two-wire interface for

the first ICN is connected to the Mini Link/EXT terminal block labeled ICN0 while the

two-wire interface for the second ICN is connected to the Mini Link/EXT terminal block

labeled ICN1.

8. Instrument address is properly configured in hardware and software.

9. Mini Link/EXT ICN device address (as set by BCD switch U1) does not conflict with

any instrument ICN device address.

NOTE: Under some circumstances, line loss and/or ground loops may cause

significant voltage differences between the External Mini Link and the field

instruments. If you expect that this may be the case, attach a ground wire

between the field instruments and the External Mini Link ICN0 or ICN1 terminal

block.
