the INIIL02 interface until all the steps in the next three sub-
sections have been completed.
CHECKING THE MODULE MOUNTING UNIT FOR -30 VDC
1. Face the rear of the cabinet. Locate the -30 VDC faston. It
is the second faston from the top on the back of the MMU back-
plane.
2. Check for -30 VDC with respect to system common at the
-30 VDC faston.
NOTE: If the module mounting unit does not use -30 VDC, the sec-
ond faston from the top on the back of the MMU backplane supplies
5 VDC.
3. If there is -30 VDC present then either set INIIT03 jumper
J5 to the 30 V position or disconnect -30 VDC from the module
mounting unit (refer to
Remove -30 VDC from the module mounting unit by removing
the supply wiring from the -30 VDC faston.
4. For additional information and/or assistance, contact
Bailey Controls technical support.
INIIT03 INSTALLATION OPTIONS
There are two installation options available. The first option
applies to systems that do not have -30 VDC power. The sec-
ond option is for systems that have -30 VDC power.
1. Set J5 to MODB when installing the INIIT03 module in a
module mounting unit that does not have -30 VDC on the mod-
ule mounting unit. Position three of dipswitch UUB0 is set to
zero for Controlway.
or
2. Set J5 to 30 V when installing the INIIT03 module in a
module mounting unit that has -30 VDC on the module
mounting unit. Pole three of dipswitch UUB0 is set to one for
module bus.
ISOLATING CONTROLWAY AND I/O EXPANDER BUS
The INIIT03 INFI-NET to INFI-NET Transfer Module must have
a Controlway or module bus that is dedicated to the INIIL02
interface. In redundant applications both the primary and sec-
ondary INIIT03 modules share this isolated Controlway or
module bus. Additionally, each INIIT03 module in a redundant
interface must have its own I/O expander bus. The INNIS01
modules communicate to their respective INIIT03 modules
through these isolated I/O expander buses. Figure
