*IFLC is the value of IFLC for OLR#2 if F3 is not set to OFF. If F3 is OFF, IFLC is the value of IFLC for OLR#1.

2.To change the setting, you must be in program mode.

3.To change the setting, press the UP or DOWN key to display the setting options, then press ENTER to select the setting that is shown. The display blanks while the ENTER key is pressed.

F15 - Display Current

1.Press the LIST key to view the instantaneous line currents or the average instantaneous line current. (The LIST key is disabled for full voltage, part-winding starters.) For instanta- neous line currents, the display shows the phase designator (A, b, or C) in the left-most character followed by three significant digits of the value of the current. For the average instantaneous line current, four digits are displayed without a phase designator.

a.Because only four characters can display at a time, individual line currents of 1000 amps and above are displayed as three dashes following the phase designa- tor, e.g., “A - - -.”

b.For sizes 1A, 1B, and 1C, the current is displayed to the nearest 0.1 amp for currents less than 100 amps; for 100 amps and above, currents are displayed to the nearest 1 amp. For sizes 2A, 2B,3, 4, and 5, the current is displayed to the nearest 1 amp. For size 6, current is displayed to the nearest 2 amps.

2.To view another line current, press the UP or DOWN key to scroll through the four selections.

3.The ENTER key is disabled for this function.

4.Press the (F)unction key to go to other functions.
