Description
Trip classes are defined by industry standard and affect the time to trip
once an overload condition is realized. This delay is to avoid nuisance
tripping, but still properly protect the motor. This is from the motor
nameplate.
Overload alarm level, generates a warning when the thermal capacity
reaches this percent.
Thermal Overload Reset Threshold. Level where reset is allowed.
The Stall protection monitors the average phase current as a percentage
of FLA (Nominal Current) of the motor and will trip the motor if the current
exceeds the set threshold. The stall protection is only active as the motor
transitions from the starting to running states.
Jam Trip Level, when exceeded and following the Jam Trip Delay time
will generate a trip.
Jam Alarm Level, when exceeded and following the Alarm Delay Time in
the Protections/General category, will generate a warning.
