Page 69 C70 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 C70 input and the debounce time setting in the C70 relay is low enough.
Page 70 This example is for illustrative purposes only and the calculations present the worst-case scenario. In practice, the value of debounce time can be lower. Contact input ON state impedance used in the calculation of the discharge period is based on the following table. 3-22 C70 CAPACITOR BANK PROTECTION AND CONTROL SYSTEM – INSTRUCTION MANUAL...
Page 71 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 192 Some customers prefer very low currents to display as zero, while others prefer the current to display even when the value reflects noise rather than the actual signal. The C70 applies a cut-off value to the magnitudes and angles of the measured currents.
Page 193: Clear Relay Records
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 C70 responds to rising edges of the configured FlexLogic operands, they must be asserted for at least 50 ms to take effect.

Page 251 PRODUCT SETUP File transfer by IEC 61850 The C70 supports file transfer by IEC 61850. The approach is as follows, using the SISCO AX-S4 61850 client software as an example. In the AX-S4 61850 Explorer window, click the Tools menu and access the SISCO File Transfer Utility.
Page 252 NUMBER: 0 The Trivial File Transfer Protocol (TFTP) can be used to transfer files from the C70 over a network. The C70 operates as a TFTP server. TFTP client software is available from various sources, including Microsoft Windows NT. The dir.txt file obtained from the C70 contains a list and description of all available files, for example event records and oscillography.
Page 253 COMMUNICATIONS  PROTOCOL connected to a maximum of two masters (usually either an RTU or a SCADA master station). Since the C70 maintains two sets of IEC 60870-5-104 data change buffers, ideally no more than two masters actively communicate with the C70 at one time.
Page 254 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 C70 sets the invalid bit in the time stamp of a time-tagged message.
Page 255 Spontaneous transmission occurs as a response to cyclic Class 2 requests. If the C70 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 256 FlexAnalog operands. The measurands sent are voltage, current, power, power factor, and frequency. If any other FlexAnalog is chosen, the C70 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).

Commands are received as General Command (Type Identification 20). The user can configure the action to perform when an ASDU command comes. A list of available mappings is provided on the C70. 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 259: 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 C70 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 260 See the Order Codes section in chapter 2 for details. The C70 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 261 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 C70 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 262 C70 clock is closely synchronized with the SNTP/ NTP server. It takes up to two minutes for the C70 to signal an SNTP self-test error if the server is offline.
Page 263: User-Programmable Fault Report
 2:00 The C70 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 264: Oscillography
The user programmable record contains the following information: the user-programmed relay name, detailed firmware revision (x.xx, for example) and relay model (C70), 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).

Figure 5-73: UR architecture overview The states of all digital signals used in the C70 are represented by flags (or FlexLogic operands, which are described later in this section). A digital “1” is represented by a set flag. Any external contact change-of-state can be used to block an element from operating, as an input to a control feature in a FlexLogic equation, or to operate a contact output.
