Some characteristics can be modified for different situations. Normally this subgroup will
not require changes.
• DEFAULT MESSAGE CYCLE TIME:
If multiple default messages are chosen, the display
automatically cycles through those messages. The display time can be changed to
accommodate different user preferences.
• DEFAULT MESSAGE TIMEOUT:
If no keys are pressed for a period of time, the relay
automatically scans a programmed set of default messages. This time can be user-
defined to ensure messages remain on the screen for a suitable time while entering
settings or actual values. Once default scanning starts, pressing any key returns the
last message viewed.
• AVERAGE MOTOR LOAD CALCULATION PERIOD: This settings adjusts the period of
time over which the average motor load is calculated. The calculation is a sliding
window and is ignored during motor starting.
• TEMPERATURE DISPLAY: Temperature measurements may be displayed in either
Celsius or Fahrenheit. Each temperature value is displayed as °C or °F. RTD settings are
always displayed in degrees Celsius.
• TRACE MEMORY TRIGGER POSITION: Sets the trigger position for waveform capture.
This value represents the percentage of cycles captured and recorded in the trace
memory buffer prior to the trigger (trip).
• TRACE MEMORY BUFFERS: Sets the number of traces to capture and the number of
cycles for each of the 10 waveforms captured. Note: 10 waveforms are captured for
each trace, showing all currents and voltages.
• DISPLAY UPDATE INTERVAL: Sets the duration for which the metered current and
voltage readings are averaged before being displayed. It does not affect relay
