701 Motor Protection Relay Date Code 20010719
Settings Calculation
Introduction
4.2
Sequential Events Recorder (SER) Settings. Lists settings that configure the
relay sequential events recorder (SER) function.
When you calculate the protection element settings to protect your motor, proceed
through the subsections listed earlier. Skip the RTD- and voltage-based protection
subsections if they do not apply to your specific relay model or installation. As you
calculate the settings, record them using the SEL-701PC software settings function. If
a PC is not available, you can manually record the calculated settings on a photocopy
of the Settings Sheets found in Appendix F: SEL-701 Relay Settings Sheets.
If you record the settings using the SEL-701PC software, you can download them
directly to a relay, or save them to a file for future download. If you record the settings
manually, you can enter them using the front-panel Set Relay function, or the front-
panel serial port and the Access Level 2 commands listed below.
See Section 3: SEL-701PC Software for more information on SEL-701PC
software. Section 5: Front-Panel Operation includes information on using the front-
panel interface; Section 6: ASCII Serial Port Operation includes details on using the
serial port SET command.
