Manual
KVCG202/EN M/H
An address between 1 and 254 that identifies the relay when interconnected by a
communication bus. These addresses may be shared between several communication
buses and therefore not all these addresses will necessarily be available on the bus to
which the relay is connected. The address can be manually set. Address 0 is reserved
for the automatic address allocation feature and 255 is reserved for global messages.
The factory set address is 255.
000C SYS Plant Status [READ]
Plant status is a 16 bit word which is used to transport plant status information over the
communication network. The various bit pairs are pre-allocated to specific items of plant.
000D SYS Control Status [READ]
The control status act like software contacts to transfer data from the relay to the master
station controlling communications.
000E SYS Setting Group [READ]
Where a relay has alternative groups of settings which can be selected, then this cell
indicates the current group being used by the relay. For KVGC202 it is either (Group 1)
or (Group 2).
000F SYS LSB Stage [READ]
Cell 000F displays the level of load shedding/boosting at all times. The load
shedding/boosting can be initiated either by energising opto inputs or via K-Bus.
The opto inputs will override the commands over the serial port. The level of load
shedding/boosting are displayed in this cell.
<Level 0> = “None” – All stages reset
<Level 1> = “Vred1” – Level 1 setting selected
<Level 2> = “Vred2” – Level 2 setting selected
<Level 3> = “Vred3” – Level 3 setting selected
When the auxiliary supply to the relay is interrupted the states of the load
shedding/boosting is remembered. This ensures that the level of load shedding/boosting
is not caused to change by interruptions of the auxiliary supply.
0020 SYS Logic Status
This cell indicates the current state of opto-isolated logic control inputs.
0021 SYS Relay Status
This cell indicates the current state of the output relay drives.
0022 Alarms
Indicates current state of internal alarms.
