Dipswitch LLB3 - Module Options
Dipswitch LLB3 sets additional module options. This dipswitch
should be set to the user settings shown in Table
Jumpers J1, J2, J4 and J5
There are four jumpers on the MFP board. These jumpers are
for special MFP hardware applications. They define the
RS-232-C diagnostic terminal as data terminal equipment
(DTE) or data communication equipment (DCE), define the
type of SRAM contained on the SRAM modules, enable the
machine fault timer and enable the MFP module to operate in
a module mounting unit that uses -30 VDC. Refer to Table
for an explanation of the function of each jumper.
NOTE: Jumper J4 is for Elsag Bailey development personnel
usage only. It is used to disable the machine fault timer circuit. If
this function is disabled (jumper pins connected) and a problem
develops in the MFP module, the module will not halt, which may
result in configuration corruption and unpredictable module outputs.

J4
Open
MFT disable jumper. Must remain open for normal operation.
J5
30V
Disconnects Controlway for operation in module mounting units that have
-30 VDC (early Network 90).
MODB
Allows operation in module mounting units that have Controlway communi-
cation. This setting must be used if dipswitch UUB0 selects Controlway.
NOTES:
1. Used by Bailey Controls Company service personnel. The J1 setting does not affect the module during normal operation.
2. Jumper J2 must be set to 4-1 for all firmware levels.
