8G – Low Current Flag
The EMX4i 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
Default:
50%
Description:
Sets the level at which the low current flag operates, as a
percentage of motor full load current.
8H – High Current Flag
Range:
50% - 600% FLC
Default:
100%
Description:
Sets the level at which the high current flag operates, as a
percentage of motor full load current.
