Rotating Default Display (Only on Models With LCD)
To program a display point to display one of the Breaker Monitor outputs
above, first enter the two-character sequence :: (double colon) followed by the
name of the desired breaker monitor output (e.g., EXTTR, CTRLTR,
CTRLIA, etc.).
If the display point setting does not match the format correctly, the relay will
display the setting text string as it was actually entered, without substituting
the breaker monitor output value.
Displaying Breaker
Monitor Outputs
Example
This example demonstrates use of the rotating display to show metering
quantities automatically on the rotating default display. This example will set
the EXTTR CTRLTR, CTRLIA, EXTIA, and WEARA to display in the
rotating default display.
Set the following:
Setting DPn = 0 and using the DPn_0 in the text settings allows the setting to
permanently rotate in the display. The DPn logic equation can be set to control
the text display-turning it on and off under certain conditions. With the relay
set as shown above, the LCD will show the following:
