Jumper Settings
There are five jumpers on the NPM circuit board. Refer to
Figure
for jumper locations. Jumpers J1 through J4 direct
signals to the termination unit or module. These jumpers are
factory set with pin one and pin two connected together.
Do
not change these jumper settings.
Jumper J5 disconnects -30 VDC, supplied in early Network 90
systems, from the NPM module. This jumper is factory set with
pin one and pin two connected. This setting allows the module
to function in early Network 90 systems (-30 VDC supplied to
modules) or limits communication to the module bus in INFI
90 OPEN systems. Connect pin two and pin three together to
use the module on the Controlway. Refer to Table
for more
information.
NOTE: Two through holes labeled J6 are located at the front of the
NPM circuit board. These are for Elsag Bailey development person-
nel only. Connecting header pins and a jumper will disable the
machine fault timer circuit. If this function is disabled and a problem
develops in the NPM module, the module will not halt which may
result in configuration corruption and unpredictable module outputs.
INNPM11 MODULE INSTALLATION
If the NPM module dipswitches and jumpers are properly con-
figured, it is ready to be installed in the module mounting unit.
CAUTION
Always operate the NPM module with the machine fault timer
circuit enabled. Unpredictable module outputs may result if the
machine fault timer circuit is disabled. These unpredictable
module outputs may adversely affect the entire communication
system.
