machine interface (HMI).

•Installation procedures, dimension drawings, and connection diagrams.

•Description of the front panel HMI and the ASCII command interface with write access security

procedures.

•A summary of setting, metering, reporting, control, and miscellaneous commands.

•Testing and maintenance procedures.

•Description of BESTCOMS graphical user interface (GUI).

WARNING!

TO AVOID PERSONAL INJURY OR EQUIPMENT DAMAGE, ONLY QUALIFIED

PERSONNEL SHOULD PERFORM THE PROCEDURES PRESENTED IN THIS

MANUAL.

NOTE

Be sure that the relay is hard-wired to earth ground with no smaller than 12 AWG

copper wire attached to the ground terminal on the rear of the unit case. When

the relay is configured in a system with other devices, it is recommended to use a

separate lead to the ground bus from each unit.

Firmware

Version/Date Change

1.14.05/06-03 Corrected ND timer problem.

Enhanced in-house diagnostics.

1.14.04/10-02 Corrected triggering problem of 2nd oscillography record.

Allowed the differential alarm to be disabled through SA-DIFF serial command.

Improved SER most recent events reporting.

Improved 62 timer function.

Corrected help text for SG-TARG command.

Allowed Trip Led to turn off when current is removed and SG-TARG=0.

Updated 87ND time delay settings.

Correctly improper display of Q demand on LCD.

Moved the degree symbol to the proper location on the LCD for the GND

current.

Improved 50TQ and 51Q time delay functions.

1.14.03/06-01 Fixed the SG-DI command (Setting Group-Demand Interval) so that it now

recognizes a demand interval of three or more digits as being “out of range”.

Added improvements to DNP 3.0, Level 2 protocol.

Added new “Password Security” parameters to Modbus protocol.

Modified display of Phase Angle information (HMI and reports) so that an

asterisk (∗) appears in the angle position if the measured current is below 1%

of rated current (0.05 A for a 5 A relay, 0.01 A for a 1 A relay).

1.14.02/05-01 Corrected firmware problems with Modbus and DNP protocols.

1.14.01/09-00 Added reporting of the protocol option to the COM2 setting screen on the LCD

HMI.

to 10 characters instead of 16 characters. This problem occurred with version

1.13.01.

Added Mode 6, Latching Timer to 62 timer functions.

Added DNP 3.0 Protocol.

Application

Program

Firmware

Version/Date Change

1.13.01/11-99 Added option to select Percent of Average Restraint Current operating

characteristic to the 87R, Percentage Restrained Differential element.

Added Modbus protocol option.

Improved COMTRADE oscillography recording function as follows:

•Provided user setting to partition the 240 cycles of oscillography memory to

provide control over the length of the records.

•Doubled available oscillography memory to 480 cycles when enhanced

recording option is present.

•Added ∗.hdr file in addition to the two files required by the COMTRADE

standard (∗.cfg and ∗.dat) to provide additional information useful in

analyzing the data contained in the oscillographic record.

Improved target reporting function such that the Trip LED on the relay front

panel only latches when there are targets to be displayed on the HMI. The

pickup condition, indicated by the Trip LED flashing, is now a higher priority

than latching to indicate that targets are being displayed on the HMI.

Corrected problem with the 51 inverse overcurrent timing algorithm that could

cause an element to time out too fast when using the V2 curve.

1.12.01/06-99 Improved current check record diagnostic routine.

Corrected problem that caused magnitude in several reporting functions to be

reported in primary amps squared.

Changed several setting defaults.
