7M – Low Current Flag
The MVE has low and high current flags to give early warning of abnormal operation. The current flags can be
configured to indicate an abnormal current level during operation, between the normal operating level and the
undercurrent or instantaneous overcurrent trip levels. The flags can signal the situation to external equipment via
one of the programmable outputs.
The flags clear when the current returns within the normal operating range by 10% of the programmed flag value.
Range: 1% - 100% FLC
Description: Sets the level at which the low current flag operates, as a percentage of motor full load current.
7N – High Current Flag
Range: 50% - 600% FLC
Description: Sets the level at which the high current flag operates, as a percentage of motor full load current.
7O – Motor Temperature Flag
The MVE has a motor temperature flag to give early warning of abnormal operation. The flag can indicate that the
motor is operating above its normal operating temperature but lower than the overload limit. The flag can signal the
situation to external equipment via one of the programmable outputs.
Range: 0% - 160%
Description: Sets the level at which the motor temperature flag operates, as a percentage of the motor's
thermal capacity.
