Published date: 12 July 2018

Issue:
Modbus Q1 Input Breaker status does not change state

Product line:
NAM Galaxy 5000


Environment:
NAM Galaxy 5000


Cause:
Modbus Q1 Input Breaker status does not change state

Resolution:
The 66061 JBUS/Modbus manual was updated May 2018 to reflect the correct Modbus register for NAM Galaxy 5000 Q1 Breaker status.  The Q1 Modbus register is only monitored on EMEA Galaxy 5000/5500 UPSs.  For NAM Galaxy 5000 customer must monitor KA1 for Q1 Breaker status change.  EMEA UPSs can monitor the KA1 status as well but KA1 is optional on EMEA UPSs.
From the 66061- JBUS/Modbus manual
