Smart Motor Management vs. Traditional Maintenance“Wait ‘til it trips”
Traditional motor control circuits use thermal, or electronic, overload relays to protect electric motors from the effects of heat generated from mechanical or electrical overload conditions.
When the overload relay detects an overload condition of sufficient magnitude and duration, a normally closed contact on the overload relay opens, turning the protected motor off.
what happens to the process?? When the overload trips ….

When the overload trips …. • Was it caused by a mechanical load problem? (bearing, poor maintenance, etc.)
• Was it caused by a motor problem?
• Was it caused by an electrical power problem?
• What was happening when the motor tripped?
What needs to be corrected to restore the process?

Smart Motor Management vs. Traditional Maintenance“Wait ‘til it trips”
A tripped overload relay causes:• Unexpected shut downs
• Unidentified reason for the trip
• Potentially hazardous conditions
• Potential scrapped material
• Potential lost production

Smart Motor Management vs. Traditional MaintenanceTime Based or Preventive Maintenance
Time based maintenance does not “wait ‘til it trips”. It is:• based on a presumed schedule, much like the maintenance schedule for a car.
• often scheduled around planned shut downs.
• can lead to unnecessary maintenance.
• not able to identify parts that are nearing the end of their service life.

Smart Motor Management vs. Traditional Maintenance“Wait ‘til it trips” or Preventive Maintenance
Thermal overloads (bimetallic) and basic electronic overloads (ESP200) provide limited protective functions. The additional protective functions on ESP200 do not annunciate the reason for the trip.
Traditional motor maintenance relies on traditional motor protection devices.

Smart Motor Management vs. Traditional Maintenance“Wait ‘til it trips” or Preventive Maintenance
Traditional motor maintenance• Relies on traditional motor load protective devices.
• Offers little help in troubleshooting the cause of the trip.
• Does little to prevent unwanted shut downs caused by dynamic changes to the protected loads.

Smart Motor Management vs. Traditional MaintenanceCondition Based (Predictive) Maintenance.
Condition based, or Predictive Maintenance is based on historical load information, such as:• Operating hours
• Number of starts
• Number of trips
• Load data ($$$)

Smart Motor Management vs. Traditional MaintenanceCondition Based (Predictive) Maintenance.
Condition based, or Predictive Maintenance requires gathering information. But how?
Traditional devices only indicate the present condition of the connected load.

Condition Based, or Predictive Maintenance requires that operating information for the connected load be gathered and stored to identify conditions that require maintenance. More information leads to more effective predictive maintenance.

Enhanced capabilities allow the user to:
• tailor protective functions to the load.
• get warnings of developing problems before a trip occurs.
• gather dynamic load information.
• select the response of the protective device.
• know why the device tripped.

Smart Motor Management vs. Traditional MaintenanceCondition Based (Predictive) Maintenance.
There are significant benefits from employing a Condition Based Predictive motor maintenance program:• Smart motor management provides real time, dynamic motor and load data to facilitate Predictive motor and load maintenance.
• Smart motor management includes enhanced monitoring and protective functions.
• Smart motor management allows selected responses to monitored motor or load conditions.
• Smart motor management can alert the user to an impending problem and prevent unwanted shutdowns.
•Smart motor management alerts the user as to the cause of a trip or warning, simplifying maintenance.
