4.6 DC/AC inverters/static bypass switch)
If inverters (with or without static bypass switch STS) are intergrated in the system, the status and
failure messages respectively are provided by the UPC4 such as for the most of the other CAN devices.
ATTENTION!
If a system is combined with an STS, there is the following difference:
compared to a system without STS the UPC4 is only sniffing for inverter value
via CAN bus because the inverters get their threshold values by the STS. Tha
means that in this case the configuration of the inverters have to be done a
the STS.
But nevertheless monitoring is done by the UPC4; "Event No Can" and miscellaneous failures
resp
ectively are provided by the UPC4 in the same way as for a system without STS.
For mains monitoring additionell measuring modules ar
e available. E.g. the mains monitoring board
(MMB) measures AC voltages and currents as well in order to provide the values to the UPC4. These
values also can be monitored by the UPC4.
4.7 Virtual measured values system
In the virtual measured values system to each input the source can be freely allocated.
Example: To the input "Vload" the source "BU1_V2" or e.g. a vo
ltage input of a BMB can be allocated.
That means that the freely allocated measuring input complies with the load voltage (Vload).
(For details please see section 6.5.1 Assignment measured values
).
4.8 Signal concept/alarm signalling/event list
Within the UPC4 different events such as e.g. "V> Vload", "Battery operation", "INV no CAN", "Digital
input1" are stored. These events can be freely allocated to each available output.
If one of the events is active, the allocated output is set.
Please consider that outputs also can be inverted at configuration.
(For details please see section 6.7.3 Signals Sw mode
).
Following outputs are available:
Disable Signals
Error state
Event history
Modem/Traps
Seven LEDs
12 relays
4.8.1 Error state (alarm signaling)
All events which are allocated to that output generate an alarm.
Within the failure list all existing alarms are provided with a clear event number and failure
nam
e (recallable respectively displayable by RDD, RDP, MMT, SNMP).
If a failure (alarm) is not active anymore it is not shown any lo
nger in the failure list.
