Installing the Fuse
Bailey ships a 1.0 amp/250 volt fuse (Bailey P/N
194776A11001) with each ICL. Verify that the fuse is installed
in the fuse holder marked F1. Figure
shows the location of
the fuse holder on the ICL circuit board.
Installing the Jumpers
Install the jumpers to match the impedance of the communica-
tion cable. The proper jumper settings depend on the revision
level of the termination module. To set the jumpers on termina-
tion modules that are revision A or B, follow the jumper set-
tings silkscreened on the printed circuit board. Revision C
termination modules have jumpers J5 - J12 set for LIS (regard-
less of whether an LIS or LIM is used), and J13 - J18 are set for
the cable type used. Table
shows the jumper settings for
revision C communication termination modules. Table
shows the jumper settings for communication termination
modules revision D or higher. Install the jumpers before
mounting the termination module in the termination mounting
unit.
NOTE: The revision level of a circuit board is indicated by the next to
the last digit of the alphanumeric assembly number silkscreened to
the circuit board. For example, ASSY P/N 6636980D1 indicates a
revision D circuit board).
