Range Function
* 50% 1–100%
The soft starter has low and high current flags to give early warning of abnormal operation. The current flags
FLC
can be configured to indicate an abnormal current level during operation, between the normal operating lev-
el and the undercurrent or instantaneous overcurrent trip levels. The flags can signal the situation to external
equipment via 1 of the programmable outputs.
The flags clear when the current returns within the normal operating range by 10% of the programmed flag
value.
Set the level at which the low current flag operates as a percentage of motor full load current.

Table 155: 8-9 - Motor Temperature Flag
Range Function
* 80% 0–160%
The soft starter has a motor temperature flag to give early warning of abnormal operation. The flag can indi-
cate 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 1 of the programmable outputs.
Set the level at which the motor temperature flag operates as a percentage of the motor's thermal capacity.
