Metering & Monitoring
Introduction
The SEL-701-1 Monitor features metering functions to display the present values
of current and (if included) voltage and RTD measurements. The monitor provides
several methods to read the present meter values, including:
Rotating front-panel display.
Front-panel menu.
EIA-232 serial port (using ASCII text command).
Rear-panel EIA-232 (using ASCII text command) or EIA-485 port
(using Modbus
â
protocol).
Analog output.
Motor load monitoring and trending are possible using the Load Profile function.
The monitor automatically configures itself to save available meter values every 15
minutes for 34 or 48 days.
For preventive maintenance purposes, the SEL-701-1 Monitor provides a motor
operating statistics report, available using the front panel or serial port.
Also helpful in preventive maintenance tasks, the SEL-701-1 Monitor calculates
and stores motor starting information. The monitor retains motor start reports for the
five latest motor starts. The motor start trending function stores motor start averages for
the last eighteen 30-day periods.
Metering
SEL-701-1 Monitor meter data fall into several categories:
Instantaneous metering.
Demand metering.
Max/Min metering.
Thermal metering.
Energy metering.
