6–4 489 GENERATOR MANAGEMENT RELAY – INSTRUCTION MANUAL
CHAPTER 6: ACTUAL VALUES
6.2 A1 Status
6.2.1 Network Status
PATH: ACTUAL VALUES Z A1 STATUS ZV NETWORK STATUS
This actual value appears when the relay is ordered with the Ethernet (T) option.
The
ETHERNET STATUS actual value message indicates the status of the Ethernet link,
connection, and diagnostic via three indicators. The
[] symbol indicates on, and the []
symbol indicates off. There is also a blinking indication.
The box under
LNK column indicates the Ethernet link status. If it is on, the Ethernet port is
connected to the network; if it is off, the port is disconnected. This indicator is normally on.
The box under the
CON column indicates the connection status. If on, the Ethernet port is
configured and ready to transmit and receive data. If blinking, the Ethernet port is either
active (transmitting or receiving data) or indicating an error if the diagnostic status is also
on or blinking.
The box under the
DIA column indicates the diagnostic status. If it is on, then either a fatal
Ethernet port error has occurred or there is a duplicate IP address on the network. If
blinking, then there is a non-fatal network error. Off indicates no errors.
6.2.2 Generator Status
PATH: ACTUAL VALUES Z A1 STATUS Z GENERATOR STATUS
These messages describe the status of the generator at any given point in time. If the
generator has been tripped, is still offline, and the 489 has not yet been reset, the
GENERATOR STATUS will be “Tripped”. The GENERATOR THERMAL CAPACITY USED value
reflects an integrated value of both the stator and rotor thermal capacity used. The values
for
ESTIMATED TRIP TIME ON OVERLOAD will appear whenever the 489 thermal model picks
up on the overload curve.
