this jumper disconnects Controlway Channel B limiting com-
munication to the module bus. 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 later
Network 90 and 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 unlabeled header pin holes are located at the front of
the board. These are for Elsag Bailey development personnel usage
only. They are used to disable the machine fault timer circuit. If this
function is disabled (header pins connected) and a problem devel-
ops in the MFP module, the module will not halt. This condition may
result in configuration corruption and unpredictable module outputs.
PREPARING THE MODULE MOUNTING UNIT
Preparing the module mounting unit consists of identifying the
proper slots, installing the required dipshunts, and verifying
the Controlway or module bus cable is installed.
Dipshunts
Verify that 24-pin dipshunts are in place between all module
slots on the I/O expander bus associated with one MFP mod-
ule. One dipshunt goes between each module slot to maintain
continuity. Remove any dipshunts that would connect the MFP
module to any module slots not associated with the MFP mod-
ule.

Disconnects Controlway for operation in module mounting units
that have -30 VDC (early Network 90).
2-3
Allows operation in module mounting units that have Controlway
communication. This setting must be used if dipswitch SW3
selects the Controlway.
NOTE: Shaded areas designate mandatory jumper settings.
WARNING
Disconnect power before installing dipshunts on the module
mounting unit backplane. Failure to do so will result in contact
with cabinet areas that could cause severe or fatal shock.
