set to Over current until the current drops or the starter trips on an overload.
A shear pin function can be implemented by setting the delay to its minimum value.

Description If the MX
3
detects a one cycle, average current that is less than the level defined, an under current alarm
condition exists and any relays programmed as alarm will energize. The under current timer starts a delay
time. If the under current still exists when the delay time expires, the starter Under Current Trips (F34) and
any relay programmed as fault relay changes state.
The Under Current Trip is only active in the UTS state, Energy Saver state, Current follower or while in the
Phase Control mode.
A relay can be programmed to change state when an under current alarm condition is detected.

Range

(Default: 0.1 sec)
Description The Under Current Time parameter sets the period of time that the motor current must be less than the Under
Current Level (PFN 03) parameter before an under current fault and trip occurs.
If "Off" is selected, the under current timer does not operate and the starter does not trip. It energizes any
relay set to undercurrent until the current rises.
