Page 79 G60 input even when the output is open, if there is a substantial distributed capacitance (represented by C1) present in the wiring between the output and the G60 input and the debounce time setting in the G60 relay is low enough.
Page 80 This operation of contact inputs also can be prevented by using the Auto-Burnish contact inputs or contact inputs with active impedance. Figure 3-22: Contact input connected to a contact output with resistor (R2) across the input 3-24 G60 GENERATOR PROTECTION SYSTEM – INSTRUCTION MANUAL...
Page 81 Eq. 3-2 The 2 mA current is used in case the contact input is connected across the GE Form A contact output with voltage monitoring. Otherwise use the amperage of the active circuit connected to the contact input when its contact output is open and the voltage across the contact input is third trigger threshold to calculate the resistor value.
Page 82 Consequently, the threshold voltage setting is also defined per group of two contact inputs. The auto-burnish feature can be disabled or enabled using the DIP switches found on each daughter card. There is a DIP switch for each contact, for a total of 16 inputs. 3-26 G60 GENERATOR PROTECTION SYSTEM – INSTRUCTION MANUAL...
Page 83 Contact inputs susceptible to parasitic capacitance caused by long cable runs affected by switching surges from external circuits can result in inadvertent activation of contact inputs with the external contact open. In this case, GE recommends using the contact I/O module with active impedance circuit.

Page 88 This common voltage is implied to be a power supply common. Some systems allow the shield (drain wire) to be used as common wire and to connect directly to the G60 COM terminal (#3); others function correctly only if the common wire is connected to the G60 COM terminal, but insulated from the shield.
Page 89: Irig-B
IRIG-B is a standard time code format that allows stamping of events to be synchronized among connected devices. The IRIG-B code allows time accuracies of up to 100 ns. Using the IRIG-B input, the G60 operates an internal oscillator with 1 µs resolution and accuracy.

Selected records can be cleared from user-programmable conditions with FlexLogic operands. Assigning user- programmable pushbuttons to clear specific records is a typical application 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 256 MIN TIME: 0 ms The G60 is equipped with up to two independent serial communication ports. The faceplate RS232 port is intended for local use and is fixed at 19200 baud and no parity. The rear COM2 port be used for either RS485 or RRTD communications.
Page 257 5.3.5.3 Ethernet network topology The G60 has three Ethernet ports. Each Ethernet port must belong to a different network or subnetwork. Configure the IP address and subnet to ensure that each port meets this requirement. Two subnets are different when the bitwise AND operation performed between their respective IP address and mask produces a different result.

Page 316 COMMUNICATIONS  PROTOCOL connected to a maximum of two masters (usually either an RTU or a SCADA master station). Since the G60 maintains two sets of IEC 60870-5-104 data change buffers, ideally no more than two masters actively communicate with the G60 at one time.
Page 317 PRODUCT SETUP The G60 can specify a maximum of five clients for its IEC 104 connections. These are IP addresses for the controllers to which the G60 can connect. A maximum of two simultaneous connections are supported at any given time.
Page 318 EXCH 1 DATA ITEM 1 to 20/50 from the G60 memory map can be configured to be included in an EGD exchange. The settings are the starting Modbus register address for the data item in decimal format. See the Modbus memory map in the UR Series Communications Guide for details.
Page 319 PTP, or SNTP, its time is overwritten by these three sources, if any of them is active. If the synchronization timeout occurs and none of IRIG-B, PTP, or SNTP is active, the G60 sets the invalid bit in the time stamp of a time-tagged message.
Page 320 Spontaneous transmission occurs as a response to cyclic Class 2 requests. If the G60 wants to transmit Class 1 data at that time, it demands access for Class 1 data transmission (ACD=1 in the control field of the response).
Page 321 FlexAnalog operands. The measurands sent are voltage, current, power, power factor, and frequency. If any other FlexAnalog is chosen, the G60 sends 0 instead of its value. Note that the power is transmitted in KW, not W. Measurands are transmitted as ASDU 3 or ASDU 9 (type identification value set to measurands I, respectively measurands II).

CHAPTER 5: SETTINGS PRODUCT SETUP A list of available mappings is provided on the G60. This includes 64 virtual inputs (see the following table). The ON and OFF for the same ASDU command can be mapped to different virtual inputs.
Page 324: Real Time Clock
Setup for IRIG-B is illustrated in the Installation chapter. For the Other protocols, whenever a time synchronization message is received through any of the active protocols, the G60 clock updates. However, given that IEC 60870-5-103, IEC 60870-5-104, Modbus, and DNP are low-accuracy time synchronization methods, avoid their use for synchronization when better accuracy time protocols, such as IRIG-B and PTP, are active in the system.
Page 325 See the Order Codes section in chapter 2 for details. The G60 supports the Precision Time Protocol (PTP) specified in IEEE Std 1588 2008 using the Power Profile (PP) specified in IEEE Std C37.238 2011. This enables the relay to synchronize to the international time standard over an Ethernet network that implements PP.
Page 326 When a clock on start-up discovers that it is “better” than the present grandmaster, it assumes the grandmaster role and the previous grandmaster reverts to slave. The G60 qualification mechanism accepts a potential master clock as a new grandmaster, when in a four-second interval it has received three announce messages from it, all better than the present grandmaster clock and better than any other announce in this interval.
Page 327 G60 clock is closely synchronized with the SNTP/ NTP server. It takes up to two minutes for the G60 to signal an SNTP self-test error if the server is offline.
Page 328: User-Programmable Fault Report
 2:00 The G60 maintains two times: local time and Universal Coordinated Time (UTC). Local time can be provided by IRIG-B signals. UTC time is provided by SNTP servers. The real-time clock (RTC) and time stamps reported in historical records and communication protocols can be incorrect if the Local Time settings are not configured properly.
Page 329: Oscillography
The user programmable record contains the following information: the user-programmed relay name, detailed firmware revision (x.xx, for example) and relay model (G60), the date and time of trigger, the name of pre-fault trigger (a specific FlexLogic operand), the name of fault trigger (a specific FlexLogic operand), the active setting group at pre-fault trigger, the active setting group at fault trigger, pre-fault values of all programmed analog channels (one cycle before pre-fault trigger), and fault values of all programmed analog channels (at the fault trigger).

10.2.1 CT saturation detection The saturation detector of the G60 takes advantage of the fact that any CT operates correctly for a short period of time, even under very large primary currents that would subsequently cause a very deep saturation. As a result, in the case of an external fault, the differential current stays very low during the initial period of linear operation of the CTs while the restraining signal develops rapidly.
