GE Power Management 269Plus Motor Management Relay

Offering optimum motor protection in situations where other relays cannot, the 269 Plus Motor Management Relay possesses 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

269Plus Motor Management Relay

=Motor is protected under both Acceleration and Runningconditions

The 269 Plus 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

GE Power Management

=One of eight 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-inFlexCurve™ function.

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 269 Plus develops a smoothcustom overload curve within a selected range.

Thermal ModelingThermal Modeling

The Thermal Model within the 269Plus 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 bythermal 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)
