Low Current Flag
8G –
The EMX4e 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.
High Current Flag
8H –
Range: 50% - 600% FLC
Description: Sets the level at which the high current flag operates, as a
percentage of motor full load current.
Motor Temperature Flag
8I –
The EMX4e 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.
Main Contactor Time
8J –
Range: 100 – 2000 milliseconds
Description: Sets the delay period between the starter switching the main
contactor output (terminals 33, 34) and beginning the pre-start
checks (before a start) or entering the not ready state (after a
stop). Set according to the specifications of the main contactor
used.
