F050 = Minimum Time Between Starts Lockout
Factory Setting = 0 (Disabled)
Range = 1 - 60 minutes, or 0 (Disabled)
When F050 is set to 1 through 60, the motor cannot be
restarted within the time specified after the first start. Time
between starts is calculated from the time of the first start
command to the next regardless of run time or off time.
Example:
If F050 = 15, motor will not be allowed to re-start within 15
minutes of first start.
This function is useful as a “Short-Cycle Timer” in preventing
excessive wear on motors where automatic demand control
may occasionally cycle on and off too quickly, such as
compressors or sump pumps

Internal Protection Features
The TE Series starter contains additional protection features that
are built-into the hardware and factory preset. Function F051 is
provided to alter these settings via numerical preset programming.
For maximum protection, all of these features are turned On as a
factory default and should be left that way unless changes are
necessary for service purposes, testing or to accommodate non-
standard applications. Factory default settings are as follows:

For maximum protection, all of these features are turned On as a
factory default and should be left that way unless changes are
necessary for service purposes, testing or to accommodate non-
standard applications. Factory default settings are as follows:
Phase Rotation: Protection is ON,
expected rotation sequence is set for A-B-C
Phase Current Loss (Running): Protection is ON, trips at <20% of
unit Max amps after 3 seconds of acceleration and at full speed.
Shorted SCR: Protection is ON, unit will lock out if one SCR is
shorted (no voltage drop across the SCR)
Shunt Trip: Protection is ON; unit trips if current flows in any phase
while in OFF mode.
PTC Trip: Protection is ON; unit will trip if PTC Input resistance
exceeds set value (or open).
Line Phase Loss (Stopped): Protection is ON; unit will trip if any
line voltage is not present while the unit is not accelerating or
stopped.
stopped.
F051 = Internal Protection Features
Factory Setting = 127 (all enabled)
Range = 1 – 127: Numeric value representing bit locations
F051 represents the numeric value of a byte (8 bits) of memory
which enables or disables these features. Each bit within that
byte acts like a “dip switch” to alter the associated feature, but
instead of having to open the starter case, changes can be
done via the keypad. Each function has a fixed numeric decimal
value associated with it. Adding or subtracting decimal values to
this function changes the binary (On-Off) status of each bit and
is simply done by entering the new value into F051. The Factory
Default value is F051 = 0127, which has all features On.
Numeric values for each feature are as follows:
