TE2 Series Digital Solid State Soft Starter User Manual
F042 = Over Current Trip / Shear Pin Trip
Factory Setting = 0 (Disabled)
Range = 100 - 300%, 0 (Disabled)
When a value other than 0 is entered in 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.
Note: Overcurrent trip is only enabled after motor reaches "At
Speed", it will not trip during acceleration".
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 in 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. Using the default setting, if the output
current of any phase drops below F044 for more than 2
seconds, the starter will trip.
5.6.8.a Ground Fault
F046 - F047 provides Ground Fault protection for equipment only using
the Residual Current method. Trip settings are based on the CT ratio as
shown in F074. A delay time can be set by F047 to help prevent
nuisance trips. Ground current can always be viewed in the Status
Display, shown with a "G" prefix (see section 5.3.1).
WARNING!
THIS IS NOT INTENDED TO BE USED AS
"PERSONNEL PROTECTION" GROUND FAULT!
This feature is only intended to provide a level of
equipment protection against damaging ground
currents. Ground faults are potentially dangerous
conditions and must be corrected immediately for safety of
operating personnel.
