Current and Ground Fault Protection Features
F040 – F050
set extended protection features that may be used in the
TE Series
starter. Percentages shown are all based automatically upon
the Motor FLA setting from
F001
except Ground Fault,
F046
. No
additional calculations are necessary.
Note:
All of these features are disabled at the factory and must be
enabled via user programming as follows:
F040 = Current Imbalance Trip
Factory Setting = 0 (Disabled)
Range = 5 - 30% or 0 (Disabled)
Use to set the trip level for when current imbalance between any
two phases exceeds this amount for the time specified
F041
.
F041 = Current Imbalance Trip Delay
Factory Setting = 2 seconds
Range = 1 - 20 seconds
Provides a time delay to prevent nuisance trips from short-
duration transients. Using default settings, if the difference in
output current between two phases exceeds 10% of FLA for
more than 2 seconds, the starter will trip.
F042 = Over Current Trip / Shear Pin Trip
Factory Setting = 0 (Disabled)
Range = 100 - 300%, 0 (Disabled)
When a value other than 0 is entered for
F042
, the starter will trip when the
output current of any phase exceeds the amount set and the time specified
in
F043
. This is also referred to as a “Shear Pin Trip” and can be used to
protect mechanical components from damage due to jammed loads.
F043 = Over Current Trip Delay
Factory Setting = 1 second
Range = 1 - 20 seconds
Provides a time delay to prevent nuisance trips from short-duration
transients. For example using default settings, if the output current of any
phase exceeds
F042
for more than 1 second, the starter will trip.
F044 = Under Current Trip
Factory Setting = 0 (Disabled)
Range = 10 - 90%, or 0 (Disabled)
When a value other than 0 is entered for
F044
, the starter will trip
when the output current of any
phase drops below the amount set,
and the time specified by
F045
. This
fault condition is often referred to as
a “Load Loss Trip” and can be used
to detect a broken shaft, V belt or
other mechanical drive system
component failure. In pumping
applications, this can be used as a
“Loss of Prime” trip.
F045 = Under Current Trip Delay
Factory Setting = 2 seconds
Range = 1 - 60 seconds
Provides a time delay to prevent nuisance trips from short-
duration transients. If using the default setting, the output current
