Description
Selectable Class 5-30, and S. Trips if the current integrator exceeds the
trip point.
Trips if the measured current is greater than the trip point setting for a
time that exceeds the over current trip time setting.
Trips if the measured kW is greater than the kW trip point setting
continuously for a time that exceeds the over power trip time setting.
Trips if the measured kW is less than the kW trip point setting
continuously for a time that exceeds the under power trip time setting.
Trips if the measured resistance of the motor windings is less than
insulation check resistance fault/alarm trip threshold.
Trips if the average of the 3 line-to-line voltages exceeds the nominal
voltage setting by the over voltage percentage setting continuously for a
time exceeding the over voltage trip time setting.
Trips if the average of the 3 line-to-line voltages is lower than the nominal
voltage setting by the under voltage percentage continuously for a time
exceeding the under voltage trip time setting.
Trips if any of the 3 measured phase currents deviates from the average
current by a value greater than or equal to the trip percentage setting.
Trips if the L-G voltage of any phase is more than 40% lower than the
average voltage.
Trips if any of the 3 measured line-to-line voltages deviates from the
average line-to-line voltage by a value greater than or equal to the
voltage phase unbalance trip percentage setting for a time exceeding the
voltage phase unbalanced trip time setting.
Trips if run command is triggered at a rate exceeding the start limit
divided by the limit period.
Trips if the current exceeds 300% of the calculated FLA setting for 0.5
seconds, the current is flat or increasing and the power factor is not
changing. This protection is active during the first ten seconds of
operation after a start.
Trips if the current exceeds 300% of the FLA for 0.5 seconds, the current is
flat or increasing and the power factor is not changing. This protection is
active after the first ten seconds of a start event and after the FLA has
been determined.
Trips ten seconds after current is detected following a contactor closure, if
the average current is above 200% of the FLA setting and still declining.
Trips if the measured peak inrush is outside the range of 400% to 1400%
of the FLA/SFA setting. This protection is only active during each start
sequence and for 10 seconds after every start.
temperature setting.
Trips if the phase order detected is different than phase order setting of
either A-B-C or
A-C-B.
Alarms if the starter detects current flow above a threshold of 0.2 A while
the starter is in the stopped state.
