Real Time Clock; Fault Reports - GE L90 Instruction Manual

5 SETTINGS
The Modbus User Map provides read-only access for up to 256 registers. To obtain a memory map value, enter the desired
address in the line (this value must be converted from hex to decimal format). The corresponding value is dis-

lines incremented by "1". An address value of "0" in the initial register means "none" and values of "0" will be dis-

These settings can also be used with the DNP protocol. See the DNP Analog Input Points section in Appen-

MESSAGE
If the L90 Channel Asymmetry function is enabled, the IRIG-B input must be connected to the GPS receiver
and the proper receiver signal type assigned.
NOTE
The date and time for the relay clock can be synchronized to other relays using an IRIG-B signal. It has the same accuracy
as an electronic watch, approximately ±1 minute per month. An IRIG-B signal may be connected to the relay to synchronize
the clock to a known time base and to other relays. If an IRIG-B signal is used, only the current year needs to be entered.

The L90 relay supports one fault report and an associated fault locator. The signal source and trigger condition, as well as
the characteristics of the line or feeder, are entered in this menu.
The fault report stores data, in non-volatile memory, pertinent to an event when triggered. The captured data contained in
the FaultReport.txt file includes:
• Fault report number
GE Multilin
values can be entered as required in any of the register positions.
