Verify Other Set Points, as Appropriate
Consult Functional Testing found later in this section for guidelines on testing and verifying set points of
other protection and control functions.
Report and Alarm Functions
Just prior to placing the relay in service, the following reporting and alarm functions should be reset
and/or verified. For details on how to use the optional LCD HMI or the ASCII command interface to enter
or edit relay operating values. See Sections 10 and 11, respectively.
Clock Display
Set the real time clock to the current date and time. If an IRIG input is used, day and time are
automatically synched to the IRIG source. But note that the IRIG time code signal does not contain the
current year information thus necessitating the entry of the year.
Reference Commands: RG-TIME, RG-DATE
Reference HMI Screen: 4.6
Refer to Section 6, Reporting and Alarm Functions, Clock, for setting details.
Energy Data and Demand
Read, change or reset KWH and KVARH records. If the Demand Functions feature of the relay is
enabled, use the following to reset the peak current, watt and var demand registers to "0" or a pre-existing
value:
Reference Commands: RE, RD, RD-<pp>
Reference HMI Screens: 4.4.1.x, 4.4.2.x, and 4.4.3.x
Refer to Section 6, Reporting and Alarm Functions, Energy Data and Demand Functions sub-sections for
setting details.
Breaker Monitoring
If the Breaker Monitoring features of the relay are enabled, use the following to reset the counter and the
duty registers to "0" or a pre-existing value:
Reference Commands: RB-OPCNTR, RB-DUTY
Reference HMI Screens: 4.3.1
Refer to Section 6, Reporting and Alarm Functions, Breaker Monitoring, for setting details.
Relay Trouble Alarms
Reset and verify that the relay trouble alarm is not illuminated. If required, alarm information can be read
by transmitting the RA or RG-STAT commands. To attempt clearing a Relay Trouble Alarm, first gain
write access to the reporting functions ("R" password) and initiate the RA=0 or RA-REL=0 commands or
press the Reset key from a STAT \ALARMS \ALARM Screen on the HMI. Refer to Section 6, Reporting
and Alarm Functions, Alarms Function, Relay Trouble Alarms, for setting details.
Major/Minor/Logic Programmable Alarms
Reset and verify that the programmable alarms, Major, Minor, and Logic, as set to meet user needs, are
not illuminated or asserted. If required, alarm information can be read by transmitting the RA or RG-STAT
commands. To reset a Major/Minor/Logic Alarm, first gain write access to the reporting functions ("R"
password) and initiate the RA=0 or RA-MAJ/MIN/LGC=0 commands or by pressing the Reset key from a
STAT \ALARMS \DET Screen on the HMI.
Refer to Section 6, Reporting and Alarms, Alarms Function, for setting details.
Targets
Reset and verify that there is no target information. Targets are reset from HMI Screen 1.1.1, \STATS
\TARGETS by pressing the Reset key or gaining write access to the reporting functions ("R" password)
and transmitting RG-TARG [= 0]. Relay target information can be read either from HMI Screen 1.1.1,
\STATS \TARGETS, or by transmitting the RG-TARG command.
Refer to Section 6, Reporting and Alarm Functions, Fault Reporting, Targets, for setting details.
