Start Data
The motor start data is taken every 5 cycles for
3600 cycles, starting 5 cycles after the phase
current magnitude exceeds 2.5 times Full Load
Amps. The relay stores the following data every
5 cycles:
•
Magnitude of A-, B-, and C-phase currents
•
Magnitude of neutral current, IN
•
% Thermal Capacity
•
Magnitude of AB, BC, and CA
phase-to-phase voltages, if included
The start data is output in a comma-delimited text
format for easy integration into computer
spreadsheets for motor starting analysis.
8.5.3
Report Format
The motor start report comma delimited format
makes the data easy to use with spreadsheets or
MSR F serial port command to view or capture
the report format. The relay responds to the
MSR F serial port command by sending a motor
start report whose data fields are filled with
zeroes. Executing the MSR F command does not
affect the statistical data stored by the relay.
8.6
Motor Start Trending
Each time the relay stores a motor start report, it
adds the motor start summary data (described in
Section 8.5.1, page 115) to the motor start
trending buffer. The motor start trending function
tracks motor start summary data for the past
eighteen 30-day periods. For each 30-day
interval, the relay records the date the interval
began, the total number of starts in the interval,
and the averages of the following quantities:
•
Motor Acceleration Time
•
Starting % Thermal Capacity
•
Maximum Starting Current
•
Minimum Starting Voltage (if voltages are
present)
View the motor start trending data using the serial
port MST command.
Note:
All the trend data collected each day are
added to nonvolatile memory at midnight.
If relay power is removed, the information
collected between midnight and power
removal is lost.
