3.2.2 Viewing alarm messages
An alarm is indicated on AES Viewer, AES Configurator or MCM API Tool of eMCM by the message.
Alarm followed by a text message. Please refer to the appendix for a complete list of possible alarm
conditions and their remedies. The measured physical motor values can be viewed during an alarm.
This is often useful in determining the reason for an alarm.
3.2.3 Fault status indication
eMCM has insufficient data to assess the status of
equipment
Motor is healthy or level of failure is under alarm
thresholds
There is a change on the supply voltage to the motor.
Temporary changes in supply voltage cause this alarm. If
this alarm is persistent check: harmonic levels, capacitors,
isolation of cables, motor connector or terminal slackness,
loose contactors, etc.
There is a possibility of a load change: 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 has been
altered deliberately, eMCM should be updated.
Plan Maintenance: There are developing mechanical
and/or electrical fault(s). Although the level of the failure
is not serious, the maintenance should be done in the next
planned outage, no later than 3 months
Do Maintenance: There are developing mechanical and/or
electrical fault(s). Maintenance and corrective action
should be performed as soon as possible.
When monitoring a motor in test mode (MONITOR, IMPROVE or UPDATE), eMCM provides a status
indication on the AES Viewer, AES Configurator. This consists of one of the items in the table above.
