EATON MP-3000 SAFETY RELAY 66D2032GX1 5A

MP-3000    Motor    Protection    Relay

IM02602002E

Instruction Leaflet for Installing, Operating, and Maintaining the

relay that is easy to set up and use.  It monitors, controls, and protects

motors against overload, thermal damage to rotor or stator, electrical

faults, and excessive starting, and many process equipment failures.

Advanced algorithms and thermal models give safe operation over a

wide range of conditions.

The MP-3000 protects 50 or 60 Hz three-phase motors of any size

or voltage level.  It can protect induction or synchronous motors, with

or without RTDs.  The relay is frequently installed in motor starters or

switchgear.

The MP-3000 Motor Protection Relay provides the following pro

tection, alarm, and control functions.  ANSI device numbers are in

parentheses.

MP-3000 features and Enhancements

The MP-3000 Motor Protection Relay incorporates the field proven

motor thermal models and sequence component measurement

techniques that were pioneered in the IQ 1000 II relay thermal models.

The MP-3000 also adds several enhancements. Significant enhance

ments and features include:

1. Recognized to meet UL 1053 Standards for Ground Fault Protec

tion Devices.

2. Power supply operates continuously at 55% of nominal supply

voltage.  It can ride through a voltage sag or loss for 30 cycles

without dropping out and taking the motor off line.

3. Optional Quick Release Drawout Case that makes removal and

replacement fast and easy.

4. New Armed/Disarmed feature for trip-free installation with Quick

Release Drawout Case.

5. User selectable trip or alarm only on relay internal failure detec

tion.

6. Real-time clock for date and time stamping of trips, alarms, and

events (Y2K compliant).

7. Expanded memory for extensive recording and logging of events,

trips, alarms, history, and motor starting current profiles.

8. Motor starting profile plot versus protection limits.

9. Easy-to-use faceplate and user interface.  Settings and data are

organized into pages under six main modes.  The modes are

Default (motor state), Monitor, View Setting, History, Logs, and

Program (change settings).

10. intel-i-trip Intelligent Overload Protection with adaptive trip char

acteristics based on RTD readings and motor operating history.

11. RTD diagnostics and communications error checking for addi

tional security against operation from RTD failures.

12. Mechanical Process Load Shedding feature provides overload

indication to control upstream processes, averting unnecessary

motor overload shutdown or jam trips, and maintaining process

continuity.

13. Download settings or retrieve metered and historical values via

the communications port.

14. Flexible user-configurable inputs and outputs for broader applica

tion.

15. Options for transition function control and monitoring on time

and/or current.

16. Emergency override function resets jogging limit functions and

clears thermal model bucket to permit restart with a time-tagged

event log.  Unit uses a secured button; this function can be dis

abled.

17. Relay can be programmed while motor runs, and new settings

are all put into effect at once in a controlled fashion.  Or, User can

set unit so programming is allowed only after motor stop.
