INTRODUCTION
Page 6 of 67
Two levels for most faults Usually used for Alarm and Trip.
Protection levels and time delay settings are individually configured using the key pad on the front panel or through
communication.
Unique Tripping / Alarm options make it possible to program any fault as an Alarm, Trip, both or none. This unique
facility also enables controlled fault Reset possibilities. Authorized key, extends the reset possibilities.
A unique calculated
"Time to Trip"
feature allows the operator or host computer to take corrective actions before
tripping.
Control Features
The MPS3000-C has the same functionality as the MPS3000 and also incorporates also control capabilities. It can
control various starting methods like Direct Online, Star Delta, Soft Starters, Reversing and Two Speeds.
Twenty optically isolated logic inputs are used to enable many types of control: Local, remote (for PLC without serial
link) or through RS485 serial link.
Two or three relays may be used to control DOL (direct online), Star/Delta, Soft-starters, Two Speed and Reversing
-starting.
Throughout the entire document MPS3000–C information is written over a gray background. Please ignore this
information for the MPS3000.
Supervision and Communication Features
A Liquid Crystal Display (LCD), together with a keypad and LEDs enables user friendly interface, accurate digital
parameters setting, actual parameters readings, and detailed trip and alarm message displays. Unauthorized setting
changes can easily be prevented by the correct use of the Authorized key input terminals.
Measured data
Phase and line voltages, Phase currents, Ground fault current, Power, Reactive
Power, Power factor, RTD temperatures (thermistor resistances) and Analog Inputs.
Calculated data Motor load in % of FLC, Equivalent motor current, Unbalance current, Thermal
Capacity, Time to trip, Time to start.
Logic inputs status Individual status of all input contacts.
Statistical data Motors running hours, Total number of starts, Total number of trips, Last start time,
last start peak current, Total Energy, minimum and maximum values of voltage,
current and frequency.
Fault data Last Trip, Last Alarm, Phase currents at time of trip, Ground fault current at time of
trip, Phase voltages at time of trip, last 10 faults with time and date stamp.
Fault Simulation – Special Test / Maintenance page allows simulation (only during first 10 hours
from auxiliary supply power up) by setting voltages currents and temperature
“actual” values. The Simulation mode can be used for periodic testing of the
relay. It can be used also for getting familiar with the MPS3000 modes of
operation and features.
RS485 serial link (with MODBUS RTU communication protocol), operating at baud rate of 1200 to 38400 bps
enables monitoring of both the "set page" and actual parameters. Changes of the "set page" parameters through
the serial link make it very easy to enter user’s set points in place of the factory default parameters. The serial link
enables remote control of both the MPS3000 and the motor.
RS485 enables 32 MPS3000 units to be connected on the same link to the host computer. When a need for more
than 32 units arises, using MMI & Data highway equipment non limited number of MPS3000's can be connected to
a host computer.
