Page 87: Introduction To Ac Sources
BACKGROUND The G60 may be used on systems with breaker-and-a-half or ring bus configurations. In these applications, each of the two three-phase sets of individual phase currents (one associated with each breaker) can be used as an input to a breaker fail- ure element.
Page 88 Source is a transformer winding, on which a three phase voltage is mea- sured, and the sum of the currents from CTs on each of two breakers is required to measure the winding current flow. G60 Generator Management Relay GE Multilin...

Page 90: Display Properties
Some customers prefer very low currents to display as zero, while others prefer the current be displayed even when the value reflects noise rather than the actual signal. The G60 applies a cut- off value to the magnitudes and angles of the measured currents.
Page 91 VOLTAGE CUT-OFF LEVEL CURRENT CUT-OFF LEVEL as valid measurements. Unless dictated otherwise by a specific application, the default settings of “0.02 pu” for and “1.0 V” for are recommended. NOTE CURRENT CUT-OFF LEVEL VOLTAGE CUT-OFF LEVEL GE Multilin G60 Generator Management Relay...
Page 92: Clear Relay Records
Selected records can be cleared from user-programmable conditions with FlexLogic™ operands. Assigning user-program- mable pushbuttons to clear specific records are typical applications for these commands. Since the G60 responds to rising edges of the configured FlexLogic™ operands, they must be asserted for at least 50 ms to take effect.
Page 93: Communications
0 ms The G60 is equipped with up to 3 independent serial communication ports. The faceplate RS232 port is intended for local use and is fixed at 19200 baud and no parity. The rear COM1 port type is selected when ordering: either an Ethernet or RS485 port.
Page 94 MODBUS SLAVE ADDRESS grammed. For the RS485 ports each G60 must have a unique address from 1 to 254. Address 0 is the broadcast address which all Modbus slave devices listen to. Addresses do not have to be sequential, but no two devices can have the same address or conflicts resulting in errors will occur.

Page 96 DNP VOLTAGE SCALE FACTOR Input points that are voltages will be returned with values 1000 times smaller (e.g. a value of 72000 V on the G60 will be returned as 72). These settings are useful when analog input values must be adjusted to fit within certain ranges in DNP masters.
Page 97 47, etc. The minimum number of binary input points that can be selected is 16 (1 block). If all of the BIN INPUT BLOCK X settings are set to “Not Used”, the standard list of 928 points will be in effect. The G60 will form the binary inputs points list from the settings up to the first occurrence of a setting value of “Not Used”.
Page 98 The G60 supports the Manufacturing Message Specification (MMS) protocol as specified by IEC 61850. MMS is supported over two protocol stacks: TCP/IP over ethernet and TP4/CLNP (OSI) over ethernet. The G60 operates as an IEC 61850 server. The Remote Inputs/Outputs section in this chapter describe the peer-to-peer GSSE/GOOSE message scheme.

The TP4/CLNP profile requires the G60 to have a network address or Network Service Access Point (NSAP) to establish a communication link. The TCP/IP profile requires the G60 to have an IP address to establish communications. These addresses are located in the !"...

C.1.6 COMMUNICATION SOFTWARE UTILITIES The exact structure and values of the supported IEC 61850 logical nodes can be seen by connecting to a G60 relay with an MMS browser, such as the “MMS Object Explorer and AXS4-MMS” DDE/OPC server from Sisco Inc.

Page 414: Analog Inputs
Deadbands for individual Analog Input Points can be set using DNP Object 34. When using the G60 in DNP systems with limited memory, the Analog Input Points below may be replaced with a user- definable list. This user-definable list uses the same settings as the Modbus User Map and can be configured with the Mod- bus User Map settings.
