Communication Bus Monitoring; Parallel Type; Message Statistics; Service Information - LEGRAND KEOR HPE Manuel De Fonctionnement

7.2.3 Communication bus monitoring

The second line of this menu gives a general indication regarding the communication between the UPS
units composing the system.
 The numbers represent the single UPS units.
 The letters M and S stand for MASTER and SLAVE respectively.
 The brackets [ ] around a letter indicate that we are working on that specific UPS unit.
 A question mark next to a number indicates that that UPS unit is not communicating on the data
bus.

7.2.4 Parallel type

The string on the second line may have two values, "POWER" or "REDUNDANT+x".
 POWER means that the parallel system is so set as to require the presence of all the UPS units
to feed the load.
 REDUNDANT+x means that the system is redundant and the redundancy index is indicated by
number "X". For example, in a system composed of 2 UPS units, "REDUNDANT+1" means
that only one of the UPS units is sufficient to feed the load.

7.2.5 Message statistics

The statistics section regarding the messages exchanged on the communication buses consists of two
different menus.
Number of messages received and percentage of reception accuracy regarding the synchronism signals.
The messages are sent by the MASTER UPS, therefore the number will only increase on the SLAVE
UPS units.
Number of messages received and percentage of reception accuracy regarding the status of the system.
The messages are exchanged between all the UPS units, therefore the number will increase on all of
them.
