options available for systems that use -30 VDC, and how to
isolate the MMU card cage for the INIIR01 interface.
Do not
attempt to install the INIIR01 interface until all the steps in the
next three subsections have been completed.
CHECKING THE MODULE MOUNTING UNIT FOR -30 VDC
To check 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.
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.
2. Check for -30 VDC with respect to system common at the
-30 VDC faston.
3. If there is -30 VDC present then either set INIIT02 jumper
J5 to the 30 V position or disconnect -30 VDC from the module
mounting unit (refer to
Turn off power to the cabinet. Remove -30 VDC from the mod-
ule mounting unit by removing the supply wiring from the
-30 VDC faston.
4. For additional information and/or assistance, contact
Bailey Controls technical support.
INIIT02 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 INIIT02 module in a
module mounting unit that does not have -30 VDC on the mod-
ule mounting unit. Pole three of dipswitch SW3 is set to zero
for Controlway.
or
2. Set J5 to 30 V when installing the INIIT02 module in a
module mounting unit that has -30 VDC on the module
mounting unit. Pole three of dipswitch SW3 is set to one for
module bus.
ISOLATING CONTROLWAY AND I/O EXPANDER BUS
The INIIT02 INFI-NET to INFI-NET Transfer Module must have
a Controlway or module bus that is dedicated to the INIIR01
interface. In redundant applications, both the primary and sec-
ondary INIIT02 module share this isolated Controlway or
