3.3 Alarms and warning messages
The internal structure of the DS300H Series UPS is modular, these are:
-PFC Rectifier module
-Inverter module
-Front panel module
Module alarms and warnings are cathegorized according to modules at the front of the Alarm or warning
message module information is added:
-RXX Rectifier alarms and warnings
-AXX Inverter alarms and warnings
-LXX LCD front panel alarms and warnings
More then one alarm can be shown on the UPS front panel with time shared order. If 4 alarms are occurred
at the same time every 2 seconds 1 message will be showed, next 2 seconds 2.message will be showed
etc..
If A00 or R00 Alarm is shown on the LCD panel we understand that there is a system fault at the related
module. We saw the message in the A00 INV FAULT = XXXX or R00 PFC FAULT = XXXX format.
Numbers shown in X determines the status code which tells the problem to us. See status code table for
details of codes.
REC CODE = XXXX XXXX SYSTEM fault occured at the rectifer module
R00 REC FAULT = XXXX Fault Rectifier AC input voltage is high
