CHAPTER 6: SETPOINTS PROTECTION ELEMENTS
MM300 MOTOR MANAGEMENT SYSTEM – INSTRUCTION MANUAL 6–41
Undervoltage Trip Delay
Range: 1 to 60 seconds in steps of 1 second
Default: 30 seconds
This setpoint specifies the time that the voltage must be less than or equal to, the
undervoltage trip level to generate a trip.
6.3.3.5 Auxiliary undervoltage
Undervoltage on the motor supply can present problems for both starting and running the
motor. The phase undervoltage element may be used to protect against these problems,
however it requires the 3 × VT input option B card to be installed. The auxiliary
undervoltage element may be used if there is no installed option B card, the relay auxiliary
VT input is derived from the motor supply, and where errors introduced by the control
power transformer can be tolerated.
The following setpoints are available for the auxiliary undervoltage protection element.
[Path: Home > Setpoints > Protection > Electrical]
Aux Undervoltage Alarm
Range: 60 to 90% of NCV in steps of 1, or OFF
Default: OFF
This setpoint specifies the auxiliary undervoltage alarm level.
Aux Undervoltage Alarm Delay
Range: 1 to 60 seconds in steps of 1
Default: 5 seconds
This setpoint specifies the auxiliary undervoltage alarm delay.
Aux Undervoltage Trip
Range: 60 to 90% of NCV in steps of 1, or OFF
Default: OFF
This setpoint specifies the auxiliary undervoltage trip level.
Aux Undervoltage Trip Delay
Range: 1 to 60 seconds in steps of 1
Default: 5 seconds
This setpoint specifies the auxiliary undervoltage trip delay.
NOTE
NOTE: NCV - Nominal Control Voltage - is calculated depending on Aux VT connection:
If Aux VT is set for Direct: NCV = MNV / root3
If Aux VT is set for VabVT, VbcVT, VcaVT, VanVT, VbnVT, VcnVT: NCV = Aux VT secondary
For additional information, refer to:
Phase undervoltage
6.3.3.6 Phase overvoltage
An overvoltage on a running motor with a constant load results in decreased current.
However, iron losses increase, causing an increase in motor temperature. The current
overload element will not pickup this condition and provide adequate protection.
Therefore, the overvoltage element may be useful for protecting the motor in the event of
a sustained overvoltage condition.
If this element is enabled, a trip or alarm will occur once the magnitude of either V
ab
, V
bc
, or
V
ca
meets or rises above the pickup level for a user-specified period of time.
NOTE
NOTE:
Phase overvoltage protection is available only when a type IO_B option card (3 × VT) is
specified in the order code.
