Rockwell Automation 2030-MLXxxx-SYSx System Multiplexer / Permissive Module - Manual (Page 6)

Section 3 (Cont'd)
Wiring the Series Connected System Multiplexer Module to the System Multiplexer / Permissive Module (EXB2-4 Connector)
3. Insert the RLS connector plug (wired to the end of the EXB interface cable) into the selected RLS port of the Control Module. Do not connect the EXB
plug to the new System Multiplexer / Permissive Module until successfully completing the following continuity check of the cable.
4. Check cable continuity at connection points on the EXB connector plug as listed in Table 5.
· Note all RLS are turned ON except the one that is switched ON or OFF for testing.
· If continuity check is unsatisfactory, review wiring done in step 2 for errors and then re-check continuity.
5. When continuity check is successfully completed, insert the EXB connector plug into the EXB port on the new System Multiplexer / Permissive Module.
If RLS status output signals are not required, close and secure the cover of the System Multiplexer / Permissive Module enclosure.
IMPORTANT: If RLS status signals are required, proceed to Section 5 for instructions on wiring of the PLC1EXB connector plug on the System Multiplexer /
Permissive Module before performing Step 6. If using the Permissive option, proceed to Section 4 for instructions on wiring the System Multiplexer / Permissive Module
to the PLC before performing Step 6.
6. Commision the unit per Chapter 3 of the ElectroGuard User Manual Revision 2030_UM003A_EN_P or later.

➊ The "ML" pilot light in the Control Module has an impedance of about 60 to 70 Ohms.
➋ With 23-85A Control Module, check with positive meter lead (+) on connection point 5 and negative meter lead (-)
on connection point 10, the impedance should be about 110K Ohms. With 110-1200A Control Module, open fuse
covers on 14FU & 16FU fuse holders before checking continuity. Impedance should be about 900K Ohms.
➌ The "System Isolated" light on the front of the RLS has an impedance of about 2K Ohms.
