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.
