Offering optimum motor protection in situations where other relays cannot, the 369 Motor Management Relaypossess the unique feature of its ability to “learn” individual motor parameters, giving it the flexibility to adapt to each application by “learning” values of motor inrush current, negative sequence current K factor, cool down rates, start thermal capacity and acceleration time.

Start and RunningStart and Running


Motor is protected under both Acceleration and Running conditions

The 369 can trigger an alarm or trip the motor based on:

normal acceleration time number of starts per hour multiple starts time between starts motor overload conditions

MAINMAIN


One of 15 standard overload curves may be programmed based on motor manufacturer’s locked rotor time capability.

Alternately the user may program in a custom curve using the built-in FlexCurve™ function.

5) Motor Current @ 80% Voltage


FlexCurve can be used to protectmotors which have different rotorand stator damage, allowing totalmotor design capacity with complete protection.

When a FlexCurve is programmed,the 369 develops a smoothcustom overload curve within a selected range.

Thermal ModelingThermal Modeling

The Thermal Model within the 369 has the ability to computethe motor I2t value based on actual motor load current.

thermal model calculates value in terms of thermal capacity used

RTDs (resistance temperature units) measuring stator temperature act as a thermal capacity check to confirm value calculated by thermal model. RTDs may be used for monitoring stator, bearing, ambient, or other temperature monitoring.

thermal capacity used is then updated to reflect the higher of the two values

MAINMAIN


MotorMatch modifies the initially entered relay parameters to match actual measured motor characteristics. The key elements include:

accumulated I2t in the memory RTD input to the memory learned cooldown time from run to stop learned cooldown time from run- overload to run-normal learned acceleration time learned negative sequence contribution (K-factor)

Motor MatchMotor Match

MAINMAIN


RTD Hot Motor RTD Hot Motor CompensationCompensation

When hot motor compensation is enabled (R option):

RTD feedback from actual stator temperature checks the thermal capacity model

User has the capability to match the motor thermal characteristics with a dual slope RTD bias curve

The two part curve allows for easy fitting of hot and cold motor damage curves to the RTD bias feature
