8-4 Front-Panel Operation Date Code 20080110
SEL-387E Instruction Manual
CMBO is W1 and W2 combined current, DIF is the differential element display, DC is the
battery monitor display, F is the measured system frequency, PWR is the calculated power
display, and ENG is the energy metering display. Use any arrow button to highlight the choice.
Then push <SELECT>.
Windings (W1, W2, W3)
If a winding has been selected, a second menu prompts the user to select the type of metering to
display. The choices are INSTantaneous, DEMand, PKD peak demand, or SECondary. Use the
right/left arrows to choose, then push <SELECT>.
Note: The harmonic spectrum metering function, the MET H serial port command, is not
available from the front panel.
If INST or SEC is selected, the relay scrolls through the primary current magnitudes, or
secondary current magnitudes and angles, for the selected winding. If DEM or PKD is selected,
a third menu appears, prompting the user to select either to DISPLAY the demand information
or to RESET the demand accumulators.
Note: RESET of the DEM or PKD is a Level 1 function and is not password protected from the
front panel.
Use the right/left arrows and <SELECT> to choose. If RESET is chosen, the relay will prompt
for a Yes/No verification of the choice. Use the right/left arrows and <SELECT> to choose. If
DISPLAY is chosen, the relay will scroll through the demand values.
Voltage (V)
If V is selected, a second menu prompts the user to select the type of metering to display. The
choices are INSTantaneous, or SECondary. Use the right/left arrows to choose, then push
<SELECT>.
Note: The harmonic spectrum metering function, the MET H serial port command, is not
available from the front panel.
If INST or SEC is selected, the relay scrolls through the primary voltage magnitudes, or
secondary voltage magnitudes and angles, for the selected voltage. Use the right/left arrows and
<SELECT> to choose.
If the Analog Input Label settings (IAW1, etc.) have been renamed, these will appear in the
displays as set.
Differential Element (DIF)
If DIF is selected, the relay scrolls through the instantaneous multiple of tap values for Operate,
Restraint, and harmonic quantities.
Battery Monitor (DC)
If DC is selected, the relay displays “Station Battery” and “VDC= nnn.n.”
