Date Code 20010719 701 Motor Protection Relay
ASCII Serial Port Operation
Command Explanations
6.15
The date entries used with the LDP command should match the Date Format
setting. If the Date Format setting equals MDY, then the dates entered should have the
format mm/dd/yyyy. If the Date Format setting equals YMD, then the dates entered
should have the format yyyy/mm/dd.
If the requested load profile records do not exist, the relay responds “No Load
Profile Data.” See Load Profiling on page 8.7 in Section 8: Metering & Monitoring for
an example load profile report.
LDP D (Level 1 or 2)
Use the LDP D command to learn how many total days of data the relay can store
and how many days remain until the oldest data is lost.
LDP R (Level 2)
LDP R removes the load profile data from nonvolatile memory.
METER (Level 1 or 2)
The METER commands provide access to the relay metering data. To make the
extensive amount of meter information manageable, the relay divides the displayed
information into five groups: Instantaneous, Demand, Energy, Maximum/Minimum,
and Thermal.
Instantaneous Metering: METER k
The METER k command displays instantaneous magnitudes (and angles if
applicable) of the measured and calculated analog quantities.
The angles are referenced to the A-phase voltage if it is included and greater than
13 V secondary; otherwise, the angles are referenced to A-phase current. The angles
range from –179.99 to 180.00 degrees.
To view the instantaneous meter values once, use the METER command. To view
the METER values k times, use the METER k command, where k is a number
between 1 and 32767.
