MOTOR RATED VOLT
Range: 100 to 20000 VAC in steps of 1 V
Default: 3000 V
This setting is used to specify the Rated Voltage of the motor.
MOTOR RATED POWER
Range: 100 to 10000 kW in steps of 1 kW
Default: 3000 kW
This setting is used to specify the Rated Power of the motor at normal (Low) speed.
ENABLE 2-SPD MOTOR
Range: Disabled, Enabled
Default: Disabled
This setting is used to enable two-speed motor functionality. When this setting is

Remote Input 1 to 32, CT Fail Alarm PKP, CT Fail Alarm OP
Default: Off
For use in two speed motor applications only, to monitor the high speed contactor
position. The status of this switch is used by the relay to select between the normal
settings used for low speed operation and the high speed settings, and to ensure that in
high speed operation the relay maintains running status when current draw is very low.
Use a form-a (normally open) auxiliary contact of the high speed (speed 2) contactor.
LOW SPEED SWITCH
Range: Off, Contact Input 1 to 10, Virtual Input 1 through 32, Logic element 1 through 16,
Remote Input 1 to 32, CT Fail Alarm PKP, CT Fail Alarm OP
Default: Off
For use in two speed motor applications only, to monitor the low speed contactor
position. The status of this switch is used by the relay to ensure that in low speed
operation the relay maintains running status when current draw is very low. Use a form-
a (normally open) auxiliary contact of the low speed (speed 1) contactor.
