Function Descriptions

Your TE Series starter is set at the factory with typical default settings
that perform well in most applications. Following are detailed descriptions
of each Function and the factory default settings.
5.6.1 Motor and Overload Function Descriptions
F001= Motor FLA
Factory Setting = 0
Range = 50 - 100% of Unit Max. Current.
Set the value of this function to the motor nameplate Full Load
Amps (FLA). Adjustments for service factor are not necessary
when programming this function. (See note below). If the motor
nameplate FLA is not available, use typical values as shown in
NEC, NEMA standard MG-1 or other reputable third party source
(motor manufacturer, etc.).

Note:
To prevent adjusting the settings beyond the starter Max Amp rating,
the range of adjustment for the Motor Nameplate FLA will vary in
accordance with the Service Factor as programmed into F002. At the
default setting of 1.0SF, the full range of adjustment from 50 - 100%
of the Max Amp rating is available. As the Service Factor is
increased, the FLA range will drop by an equal ratio. For example if
F002 = 1.15 (a 1.15 Service Factor), the maximum FLA
programmable into F001 will be limited to 85% of the starter Max.
Amp rating (100% - 15%).
F002 = Service Factor
Factory Setting = 1.0 S.F.
Range = 1.00 - 1.30
Set value according to the Service Factor (SF) data provided on
the motor's nameplate. This value affects several protection
features so it must be accurate. Setting the SF too high may
result in motor damage in an overload condition. Setting SF too
low may cause nuisance trips however; a 1.0 SF setting is safest
if SF is unknown.

Note:
The combination of F002 and F001 (FLA x SF) cannot exceed the
Unit Max Amp rating. If when programming F002 you are not allowed
to raise the setting, the combined total has been exceeded.
F003 = Overload Class During Start
Factory Setting = 10 (Class 10)
Range = NEMA / UL Class 5 - 20
Set value to the motor protection overload class required for the
application. It is recommended that you try the factory setting
first. (If possible, keep values for F003 and F004 the same.)
Increase F003 above F004 only if nuisance tripping occurs
during start. See Section 3.2 for details on trip curves.
