Set the jumpers so they relate to the type of output needed. For
common outputs (with an electrically common destination),
connect the jumper between posts 1 an 2. For isolated outputs
(with no electrically common destination), connect the jumper
between posts 2 an 3. Figure
shows the location of the
jumpers on the DSM.
Master Selection Jumpers
The two master selection jumpers on the top of the DSM deter-
mine the type of master that the DSM communicates with. Put
jumpers J17 and J18 between posts 1 and 2 for the DSM to
communicate to an LMM01 master. Put jumpers J17 and J18
between posts 2 and 3 for the DSM to communicate to an MFP,
MFC or LMM02 master. See Figure
for jumper locations.
Table
summarizes jumper information needed to configure
the DSM for installation. It lists the possible applications and
I/O jumper placement.
Termination Unit/Module Configuration
A TU connects the field device wiring to the Infi 90 system. The
terminal blocks (connection points) are located on the TU/TM.
You must configure the TU/TM to accept the digital field
inputs sent to the DSM. Refer to the Appendix for your termi-
nation unit to determine the configuration for your application.
