Introduction

1. Overview

eMCM is

the

device

that

combines

current/voltage

signal a

technique

and

motor protection

technique. It

performs

motor protection

and diagnosis at

the

same

eMCM

the

current/voltage

from

the motor

and processes

(spectrum analysis) so

that it operates as

motor

protection relay

well

motor

condition monitoring system which a

the

status of motor and

motor

While existing motor protection relay just detects current status

the

eMCM

addition,

can

predict

and

monitor motor condition

that it

ensures the motor safety

and stable

motor management.

eMCM performs motor

condition monitoring

based on

the technology

developed in NASA and

needs minimum user intervention. Furthermore, eMCM provides energy

consumption measuring, which enables user

come up

an effective

plan

for dealing

with

efficient energy

consumption.

eMCM is

convergence device which is

able to deal with protection,

condition monitoring

and energy measuring of

the motor

in one

devi

2. Features

•Provides condition monitoring and energy measuring of the motor in one device.

•Motor condition monitoring functions Watch Line, Watch Load, Electrical Faults, Mechanical

Faults

•Based on the technology developed in NASA

•Measuring functions voltage, current, power factor, frequency, power, power consumption,

unbalance, ground fault

•Provide RS-485 serial communication and Modbus ethernet communication

•External HMI module (2.7-inch LCD display)

Motor Condition Monitor and Diagnostic Functions

Status

Motor and driven system is working as expected.

Watch Line

Watch Line is usually temporary in nature and generally the

user does not need to take any action. However, it is

recommended that when this status level occurs, the user

should at least assess the extent of the change in the line

conditions, as significant changes in the line voltages and

currents may be dangerous to the motor. If the line status

change is persistent, the user should assess the root cause of

this change. For instance, it may be due to a problem in the

contactors or for inverter driven motors the settings of the

inverter may have been changed. In any case, if the root cause

cannot be remedied easily and quickly and the new voltage

supply condition presents no danger to the motor, the user

has the option to send MCM to the UPDATE mode. This will

allow MCM to learn the new voltage supply conditions, after

which the status will eventually return to normal.

Watch Load

If the process load has not been altered deliberately,

check for leakage, valve & vane adjustment, pressure

gauge faults, manometer, dirty filters (fans,

compressors). If the process is altered deliberately, device

should be updated.

Examine 1

Plan Maintenance (First Level Alarm): There are developing

mechanical and/or electrical fault(s). Although the level of the

failure is not serious, the maintenance should be done in next

planned stop or latest in 3 months.

Examine 2

Do Maintenance (Second Level Alarm): There are developing

mechanical and/or electrical fault(s). Maintenance and

corrective action should be performed as soon as possible.
