2.1 TECHNICAL SPECIFICATIONS
Overload Curves
General The RediStart Micro II comes with forty (40) standard overload curves. The 100% (no
Curves The overload can be set to;
Trip Time Accuracy ±2 seconds up to 30 seconds
trip) point is the motor FLA setting multiplied by the service factor. These curves are
shown on the next page.
NOTE: The user can display the overload by setting the overload to Off. The overload
can also be set to BYP (Bypass), which limits the charging current during ramping to
90%. One the unit has reached UTS (up-to-speed), the overload can charge the
remaining 10%. This is useful on extremely large centrifugal loads such as
centrifuges.
NOTE: When the overload counter is at a number other than 0%, the time to trip will
be lowered by this percentage.
NOTE: In heavy duty DC braking application, the overload settings may be limited to
protect the starter and motor from potential damage.
Caution must be taken when using the Bypass mode. The starter does not overload
protect the unit during the start.
OFF - no thermal overload
•
1-40 - class 1 through 40 overload in steps of 1.
•
BYP - overload bypassed during starting, class 10 once up-to-speed

Ventilation Requirements
General Provisions should be provided with the starter installation to ensure that the
temperature inside the enclosure never rises above 50°C. If the temperature inside
the enclosure is too high, the starter can be damaged or it’s life can be reduced. As a
general rule of thumb, the following ventilation guidelines can be followed.
Current Range Bottom of Enclosure Top of Enclosure
< 200 amps Fans or grills depending on enclosure size
200 to 300 amps 2 x 4” grills (12 sq.in.) 2 x 4” grills (12 sq.in.)

Benshaw installs starters under 124 amps with the heat sink protruding from the
back of the enclosure. This allows a small enclosure size while still maintaining the
cooling capability of the starter. The starter produces 4 watts of heat per amp of
current and 14 square inches of enclosure wall are required per watt of heat
generation. Contact Benshaw and ask for the enclosure sizing technical note for more
information concerning starters in sealed enclosures.

CT Mounting
General On larger horsepower starters, the current transformers have to be installed on the
power wire. To ensure that the CT is not damaged by rubbing on the power lug, the
CT should be tie wrapped to the power wire 3 inches from power lug using 2 tie wraps
in a cross pattern. Refer to the following diagram. The CTs must be installed so that
the white dot is facing the LINE side of the starter with the proper CT installed for
each phase. The metering functions will not work correctly if the CTs are not installed

CT Ratio Scaling
General Information The motor current signal scaling is set according to the motor current specified when
the starter is ordered. To ensure accurate operation, the motor current signal must be
correctly scaled for the motor current being controlled by the starter.Motor current
signal scaling may have to be changed if the motor size has been changed from the
original specification.Motor current signal scaling is accomplished by verifying the
current transformer ratio as supplied with the starter and then selecting the correct
DIP switch setting from the chart on the following page for the current transformer
ratio.
The DIP switches are:
•
ON in the right position
•
OFF in the left position
NOTE: Adjust the DIP switches only when the motor is stopped, or the switches
could be damaged.
Confirm Switch Settings To verify or change the motor current signal scaling:
•
Compare the CT ratio stamped on each CT to the CT ratio listed on the wiring
diagram supplied with the starter to ensure the correct CTs are installed.
•
Inspect the RediStart Micro II power card to ensure that the DIP switches are in
the correct positions for the applicable CT ratio and the motor full-load current

JPC19 - Fault Reset The RediStart Micro II can be set to either require a manual reset or automatically
reset after a fault occurs. The RediStart Micro II is set for manual fault reset unless
the purchase order requests that the fault reset jumper is set to automatic. The fault
reset is controlled by jumper JPC19 on the RediStart Micro II computer card (Refer to
RediStart Micro II computer card layout on page 122).

The automatic fault reset works in conjunction with the # auto resets parameter (see
page 87) and the Fault Classes sub-menu (see page 88).
The # auto resets parameter sets how many non-critical faults will be reset in one
hour. Once this number has been reached, the starter will not automatically reset the
next fault. When this occurs, the user should check the event recorder for the cause of
the faults and correct the problem.
The fault classes sub-menu allows the user to set faults as critical, non-critical,
disabled, warning relay A, warning relay B or warning relay C. When JPC19 is set to
automatic fault reset and a fault is set to non-critical, the RediStart Micro II will
automatically reset the fault.

Parameters
Parameter Usage The description and use of each parameter is described in the programming section of
the manual. Most parameters are fairly straightforward and don’t require any further
explanation. The rest of this chapter gives a more detailed description of the use of the
parameters that are more complicated to use.
Starter Modes
Description The Starter Mode sub menu (see page 54) contains parameters for selecting the type
Start Modes Curr (Current Ramp): The current ramp is ideal for most general-purpose motor
of start and stop to perform. By allowing the user to select the start and stop mode the
system can be operated in the optimal start and stop fashion for the load. Below are
the available modes along with some examples for typical applications.
control applications; Examples: crushers, ball mills, compressors, saws, and
centrifuges).
The Current Ramp applies to the following in the Starter Setup Main Menu:
Forward1 Profile, Forward2 Profile, Reverse1 Profile, and Reverse2 Profile.
TT (Tru Torque): The true torque ramp is suitable for applications that require a
minimum of torque transients during starting or for consistenly loaded applications
that require a reduction of torque surges during starting; Examples: pumps, fans, and
belt driven equipment).
The Tru Torque ramp applies to the following in the Starter Setup Main Menu:
True Torque Ramp
Tach (Tachometer Feedback): The tachometer feedback ramp is for applications
where torque transients must be held to a minimum, and the starting load is
unknown, vary, or change during the start cycle; Examples: Belts, and conveyors.
The Tachometer ramp applies to the following in the Starter Setup Main Menu:
Tachometer Setup
Stop Modes Coas (Coast): A coast stop should be used when no special stopping requirements are
necessary; Example: crushers, balls mills, centrifuges, belts, conveyor.
There is no menu that applies in the Starter Setup Main Menu.
VDCL (S Curve Voltage Deceleration): A standard open loop S-Curve voltage
deceleration is best suited for applications such as pumps and compressors.
The S Curve Voltage Deceleration applies to the following in the Starter Setup Main
Menu: Decel Setup
TT (Tru Torque): The true torque deceleration is best suited to pumping and
compressor applications where pressure surges during a stop must be eliminated.
This setup is easier than the S-Curve Voltage Deceleration and is less source voltage
dependent.
The Tru Torque deceleration applies to the following in the Starter Setup Main Menu:
True Torque Ramp
Brak (Brake): The Brake stop mode allows a static DC field to be injected into the
stator of the motor, which makes the rotor stop in a fashion similar to the way the 3
phase rotating magnetic field brings the motor up to operating speed; Examples: saws,
E-Stop applications, machine tools, and large centrifugal loads.

Current Ramp Adjustment
Current Ramp The current ramp sets how the motor accelerates. The current ramp is a linear
increase in current from the initial setting to the maximum setting. The ramp time
sets the speed of this linear current increase. The following figure shows the
relationships of these different ramp settings.

Initial Current Setting The initial current should be set to the level that allows the motor to begin rotating
within a couple of seconds of receiving a start command.
To adjust the initial current setting give the starter a run command. Observe the
motor to see how long it takes before it begins rotating and then stop the unit. For
every second that the motor doesn’t rotate, increase the initial current by 20%.
Typical loads will require an initial current in the 50% to 175% range.
Maximum Current Setting For most applications, the maximum current can be left at 600%. This will ensure
that enough current is applied to the motor to accelerate it to full speed.
The maximum current can also be set to a lower current limit. This is usually done to
limit the voltage drop on the power system or to limit the torque the motor produces
to help prevent damage to the driven load.
NOTE: The motor may achieve full speed at any time during the current ramp. This
means that the maximum current setting may not be reached. Therefore, the
maximum current setting is the most current that could ever reach the motor, and not
necessarily the maximum current that will reach the motor.
NOTE: When setting a current limit, the motor must be monitored to ensure that the
current is high enough to allow the motor to reach full speed under worst case load
conditions.
34
4.1 OPERATION
Ramp Time Setting The ramp time is the time it takes for the current to go from the initial current to the
maximum current. To make the motor accelerate faster, decrease the ramp time. To
make the motor accelerate slower, increase the ramp time.
If the ramp time expires before the motor reaches full speed, the starter will maintain
the set maximum current level until either the motor reaches full speed, the stall time
expires, or the motor thermal overload trips.
NOTE: Setting the ramp time to a specific value does not necessarily mean that the
motor will take this time to accelerate to full speed. The motor and load may achieve
full speed before the ramp time expires if the application does not require the set
ramp time and maximum current to reach full speed. Alternatively, the motor and
load may take longer than the set ramp time to achieve full speed.
Programming A Kick Current
General The kick current sets a current level that overrides the current ramp when a start is
Kick Current The kick current parameter is usually set to a low value and then the kick time is
first commanded. The kick current is only useful on motor loads that are hard to get
rotating but then are much easier to move once they are rotating. An example of a
load which is hard to get rotating is a ball mill. The ball mill requires a high torque to
get it to rotate the first quarter turn (90

seconds without the motor rotating, start over with a higher kick current setting.
Jog at Set Speed
Description The jog at set speed allows the motor to be operated at fixed low speeds. It is possible

speed. To make the motor jog in the forward direction, the starter must be told to jog
the motor by energizing the jog input. Then, the starter must be given a run command
to actually operate. Energize the jog input by applying 120VAC to terminal 4 of the
JC13 terminal block on the RediStart Micro II computer card(see computer card
layout on page 122)
The jog speed is set by the forward speed parameter (see page 64)
motor can be jogged at a fixed 20% reverse speed. On a reversing starter, the motor
can be jogged at 7% or 14% reverse speed. The 7% or 14% speed is selected by the
reverse speed parameter (see page 64).
To make the motor jog in the reverse direction, the starter must be told to operate in
the jog mode by energizing the jog input and the reverse input. Then the starter must
be given a run command to actually operate. Energize the jog and reverse inputs by
applying 120VAC to terminal 4 (jog) and terminal 6 (reverse) of the JC13 terminal
block on the RediStart Micro II computer card.

low jog currents, the motor will produce enough torque to keep the motor turning but
it won’t produce enough torque to start it. The kick current can be used to start the

increase it in 50% increments if the current is not enough.
applied. If a kick current is required, start with a 0.5 second time and continue to
increase the time until the load will rotate.
Tachometer Feedback
Description The Tachometer control ramp profile (see page 65)provides a method to linearly ramp
the speed of the system. When this control mode is selected, the starter uses a
tachometer to provide speed feedback to the starter. This mode is commonly used on
conveyor belt applications where a smooth controlled start is necessary under various
load conditions to prevent belt breakage, lifting, or excessive stretching. The
Tachometer controller consists of an inner PID current loop and an outer PI speed
control loop.
NOTE: The maximum current limit will override the speed control loop if necessary.
If the Maximum Current level is not set high enough or the load is too great, the
RediStart Micro II starter will limit the motor current to this maximum level. When
current limiting occurs, the speed profile will no longer be linear and the motor(s) will
take longer to accelerate to full speed. Therefore, if current limiting is undesirable,
this parameter must be set higher than the peak starting current during a linear
speed ramp start.
Tachometer Requirements In addition to the basic motor and starter setup variables, the following needs to done
to use the tachometer feedback control ramp:
1. Connect a tachometer with appropriate DC output voltage and correct polarity to
the Redistart Micro II power card input (terminal TBP13).
2. The tachometer feedback Start Mode is selectable as “Tach” from the Starter Modes
menu.
3. Program the appropriate variables in the Tachometer Setup menu.
4. Set the Initial Current level in either the Quick Start menu or the Forward1 Profile
menu to the desired current limit.
5. Set the Maximum Current level in either the Quick Start menu or the Forward1
Profile menu to the desired maximum current limit.

Programming The Motor Deceleration
Deceleration Control The standard deceleration control on the RediStart Micro II uses an open loop voltage
ramp. The RediStart Micro II will ramp the voltage down to decelerate the motor. The

Programmed Decel Level (%)
Decel Level 1 This sets the starting voltage of the deceleration ramp. Most motors require the
voltage to drop to around 60% or lower before any significant deceleration is observed.
Therefore, a good first setting for this parameter is 35%.
0102030405060708090100
To adjust this parameter, it is necessary to observe the motor operation as soon as a
stop is commanded. If the motor hunts (speed oscillations) at the beginning of the
deceleration, then lower the parameter by 5%. If the motor has a big drop in speed as
soon as a stop is commanded, then raise the parameter by 5%.
Some motors are very sensitive to the adjustment of this parameter. If a 5%
adjustment changes the motor from hunting to dropping in speed, then a smaller
change of 1% or 2% may be necessary.
Decel Level 2 This sets the final voltage for the deceleration ramp. In most cases, this parameter
can be set to 10% and the decel time can be used to adjust the deceleration rate. If the
motor is coming to a stop too quickly or if the starter continues to apply current to the
motor after the motor has stopped, this parameter can be increased in 5% increments
to fix this.
Decel Time The decel time sets how quicky the motor decelerates. Usually a time of 30 seconds is
a good starting point. To make the motor take longer to decelerate, increase this
parameter or to make the motor decelerate quicker, decrease this parameter.

Bypass Delay PORT can also hold a bypass contactor in for a programmed BYP Dly when the power

When the system senses a voltage disturbance in a time frame greater than the Sense
Time parameter, the power will be removed from the motor for a coast to stop, and the
Fault Dly timer will begin to time; if it is not set to OFF.
If the power disturbance ends before the programmed Fault Dly time, the motor will
restart -- if a start command is still present -- from initial to maximum current in the
specified ramp time.
If the outage lasts longer than the programmed Fault Dly time, the starter will issue
a Fault 98; “No Mains PWR.”
If Fault Dly is set to OFF, the starter will use the standard motor protection fault
delay timers to sense power disturbances.
NOTE: Starts/Hou (starters per hour), Time Start (time between starts), and BKS
Timer (backspin timer) are not incremented for PORT.
NOTE: If the system Start Mode parameter is programmed with a tachometer ramp,
the system will restart using a tachometer ramp.
disturbance is Sensed.
NOTE: The BYP Dly is fixed at 0.0 seconds to protect systems that contain an
integral bypass card.
NOTE: Caution must be taken when the BYP Dly is set above 0.0 seconds. If the
bypass contactor is energized when the power disturbance ends, the motor will start
across the line. The resulting torque may damage the system.
PORT Detection The starter can be detected in PORT operation by monitor of the PORT relay output;
Selectable on any of the programmable relays. Once programmed, this relay can be
used to feed 120VAC to input 9 of the JC13 terminal block on the computer card. This
causes the system to use the Forward/Reverse2 Profile for starting the motor.
TruTorque Acceleration Ramp
TruTorque Ramp The TruTorque ramp sub-menu (see page 72) contains the parameters that that are
used to activate and tune TruTorque Acceleration and Deceleration Control.
The primary purpose of TruTorque Control is to reduce the torque surge that occurs
as an AC induction motor comes up to full speed. This torque surge can be a problem
in applications especially in pumps and belt driven applications. In pumping
applications this torque surge results in a pressure peak as the motor comes up to
speed. In most situations this small pressure peak is not a problem. However in
selected cases, even a small pressure peak can be highly undesirable. In belt drive
applications, TruTorque prevents the slipping of belts as the motor reaches full speed.
Note: When TruTorque acceleration control is enabled the second ramp (Ramp #2)
and Kick Current functions are disabled.
TruTorque control can be very useful for a variety of applications. However it is best
used for pump and other variable torque applications. TruTorque generally should not
be used in applications where the starting load varies greatly from one start to
another.

If the value is set too high a current surge may result. If the value is set too low a “No
current at Run” fault may occur.
loads require a value around 100-110%. If the load is less than motor rating then the
maximum torque value can be decreased. If the load is hard to start or the motor is a
NEMA C or D type motor then this value may need to be increased.
If the motor reaches full speed too quickly then decrease the Maximum Torque value
by 5% and retest. If the motor does not achieve full speed, increase the Maximum
Torque value by 10% and retest.
If the motor can be started either by using default TruTorque values or current ramp
control, the Maximum Torque value can be more precisely determined so that the
motor comes up to speed in approximately the preset Ramp Time. In this case, while
the motor is running at full load, display the TT% meter on the display (see Meter
Setup for information on how to display the TT% meter). Record the value displayed
when the motor is running with full load. The Maximum Torque value should then be
set to the recorded running value of TT% plus an additional 10%. Retest with this
value to verify correct operation.
Note: When setting the Maximum Torque value the motor must be monitored to
ensure that the torque is high enough to allow the motor to reach full speed under
worst case load conditions.
Ramp Time The Ramp Time setting is the time it takes for the torque to go from the Initial Torque
Setting to the Maximum Torque Setting. To make the motor accelerate faster,
decrease the ramp time. To make the motor accelerate slower, increase the ramp time.
If the ramp time expires before the motor reaches full speed the starter will maintain
the set Maximum Torque level until either the motor reaches full speed, the stall
(UTS) timer expires, or the motor thermal overload trips.
Note: Setting the ramp time to a specific value does not necessarily mean that the
motor will take this time to accelerate to full speed. The motor and load may achieve
full speed before the ramp time expires if the application does not require the set
ramp time and maximum torque to reach full speed. Alternatively, the motor and load
may take longer than the set ramp time to achieve full speed.

NonC Non-critical fault. If this fault occurs, the starter will shut down and display the fault

options are described in the following paragraphs. See page 112 for a complete fault
code and description listing.
number and description on the display. A non-critical fault can be set to either require
a manual reset or to automatically reset.
The automatic resetting of a non-critical fault is dependant on the automatic
computer reset jumper JPC19 (see page 26). WhenJPC19 is set to auto reset (position
1-2), the starter will automatically reset the fault. The number of automatic resets
parameter (# Auto RST) on page 87 sets how many times the starter will perform this

4.1 OPERATION
Use of Overcurrent and Undercurrent
General For the over current and undercurrent trips, there are settings for the current level
Overcurrent The overcurrent parameters are for the user to set a user defined high current trip.
Undercurrent The undercurrent parameters are used to set a user defined low current trip. The

Tripping vs Running As the default, the starter will trip when an over-current or undercurrent is detected.
and the detect time. The motor current must go above or below the current level
settings for the detect time before the overcurrent or undercurrent condition is
detected. The overcurrent and undercurrent trips do not become active until the
starter is up-to-speed (UTS is shown in top line of display).
The overcurrent parameters are not used for the thermal overload. If the driven load
can be damaged by the full motor torque being applied during a stall or jam of the
driven load, the over-current should be used to prevent this.
undercurrent parameters are used to protect a driven load from running empty. A
good example of the undercurrent trip usage is a water pump. If the pump can run
dry, the undercurrent parameters can be set to detect the low current and shut the
pump down. To use this, the current could be set to 50% and the detect delay to 5
seconds to shut the pump down 5 seconds after the current falls below 50% of the
motor FLA parameter.
a programmable relay must be programmed to OCT or UCT respectively.
To keep the starter operating, the over-current fault (fault #78) or undercurrent fault
(fault #79) must be set to dis (disabled) in the fault classes sub-menu (see page 88) to
turn off the fault trip.
Once the over-current or undercurrent fault is disabled, the starter will not trip when
the over-current or undercurrent condition is detected, The relay programmed to OCT
or UCT will still operate when the condition is detected. Once the condition clears, the
relay will remain active for the programmed release delay time. The user must
monitor the relay output and take appropriate action when the relay is energized.
Overload
General The RediStart Micro II comes with a programmable overload that allows classes 1-40
Overload Classes The overload class sets the time it takes for the overload to trip when the motor
to be programmed plus an overload disable and overload bypass during starting. The
thermal overload is displayed as a percentage of overload used, with 0% representing
a “cold” overload and 100% representing a “tripped” overload. The overload always
operates on the highest phase current.
current is six (6) times the motor FLA. The overload follows an exponential curve that
gives a long trip time for slight overloads and a short trip time for large overloads.
This models the heating of a typical squirrel cage induction motor. See page 11 for the
motor thermal overload curves.
41
4.1 OPERATION
Overload Operation There are two ways that the overload can operate. The operation is changed in the
fault classes sub-menu by changing the overload lock fault (fault #90) from Crit to Dis.
When fault #90 is set to Crit;
The overload warning relay will energize when the O/L content goes above 90%
•
and de-energize when the O/L content goes back below 80%.
The starter will shut down if the overload content reaches 100%.
•
The overload lock relay will energize when the O/L content reaches 100% and
•
de-energize when the O/L content goes back below 60%.
The starter will not allow an overload reset once the overload trips until the
•
overload content goes back below 60%.
The overload relay will energize when the overload trips and will de-energize
•
when the overload condition is cleared by an automatic or manual reset.
When fault #90 is set to Dis;
The overload warning relay will energize if the overload content goes above 90%
•
and will de-energize when the overload content goes back below 80%.
The starter will not shut if the overload content reaches 100%.
•
The overload lock relay will never energize.
•
The overload relay will energize when the overload content goes above 100% and
•
will de-energize when the overload content goes back below 100%.

Running Overload When the RediStart Micro II is running the overload content will never discharge
below 30%. The overload content will always hold at any value below 30% during the
running period. As soon as the unit is stopped the overload will begin to discharge
back to 0%.
42
4.1 OPERATION
Resolving Overload Trips The National Electrical Code, article 430 Part C, allows for different overload
multiplier factors depending on the motor and operating conditions.
NEC section 430-32 outlines the allowable service factor (Serv. Fact) for different
motors as follows:
Motor Overload Multiplier
Service factor 1.15 or more 1.25
Motor temp. rise 40°C or less 1.25
All others 1.15
NEC section 430-34 permits further modifications if the service factor (Serv. Fact) is
not sufficient to start the motor:
Motor Overload Multiplier
Service factor 1.15 or more 1.40
Motor temp. rise 40°C or less 1.40
All others 1.30
Although the NEC doesn’t address the effect of the ambient temperature of the motor
location, guidance can be derived by examining NEC limits. If the motor is operating
in an ambient temperature that is less than 40°C, then the overload multiplier can be
increased while still protecting the motor from exceeding it maximum designed
temperature. The following curve gives the ambient temperature vs the correction
factor.

Example: If a motor operates at 0°C then a 1.36 correction factor could be applied to
the overload multiplier. This could give a theoretical overload multiplier of 1.36 x 1.25
or 1.70. The highest legal value of overload multiplier is 1.40 so this could be used.

If the ramp time expires before the motor has reached full speed, the starter will hold
the current at the maximum current level until the stall time expires, the motor

Reverse #2 Ramp Profile
General The reverse #2 ramp profile sub-menu contains the parameters that set the starting
ramp profile when reverse operation and the second ramp are both selected. Reverse
operation is selected by applying 120VAC to input 6 of the JC13 terminal block on the
RediStart Micro II CPU card. The second ramp is selected by applying 120VAC to
input 9 of the JC13 terminal block on the RediStart Micro II CPU card.

setting. The initial current parameter sets the current that will initially reach the
motor when a start is commanded.
If the motor does not rotate within a few seconds after a start command, the initial
current should be increased. If the motor takes off too quickly after a start command,
the initial current should be decreased.
The initial current must be set to a value that is lower than the maximum current
parameter setting.
A typical setting for the initial current parameter is from 50% to 175%.

5.9 PROGRAMMING: Starter Setup - Jog Cntrl Setup
Jog Curr. (jog current)
Description The jog current parameter is set as a percentage of the motor FLA parameter setting.
Values The jog current is adjustable from 25% to 250% in 1% increments.
Default The default value for the jog current is 50%.
The jog current parameter is used to set the maximum current that will reach the
motor while the motor is being operated in the jog at set speed mode. It should be set
to the lowest possible current level that will still operate the motor.
When a motor is operating in the jog at set speed mode, its cooling capability is
greatly reduced. Therefore, the running time of the motor is dependant on the motor
current. If the jog at set speed will be used on a regular basis, the motor temperature
should be monitored using a thermostat. The thermostat can be connected between
the power and input terminal 1 of the JC13 terminal block on the RediStart Micro II
computer card so that the starter will trip when a fault occurs. Alternatively,
temperature monitoring devices, such as thermistors or RTDs can be used. This will
prevent the motor from being overheated and inadvertently damaged.
Due to the way the jog at set speed operates, the starter may require the installation
of a 5% line reactor to eliminate harmonic problems being introduced into the power
system. This is dependent on the size of the motor in relation to the capacity of the
power system. The jog at set speed has more of an effect on a weak power system.
Max. Time (maximum time)
Description The maximum time parameter sets the time limit for continuous operation in the jog
at set speed mode. This parameter should be set to a value that doesn’t allow the
motor to be operated in the jog at set speed mode for such a length of time that
damage to the motor can occur.
During initial set-up, monitor the motor temperature to determine it’s maximum safe
jogging time and then enter this time. This can help avoid damage to the motor by
stopping the starter before the motor overheats. This parameter does not stop the
operator from stopping and re-starting the motor during jog operation which could
still lead to the operation time of the motor being exceeded. Use the timers in the
Starts Lockouts submenu to protect against this.
Values The maximum time is adjustable from 1 to 9000 seconds in 1 second intervals.
Default The default value for the maximum time parameter is 200 seconds.

motor when a start command is given and the starter is set for operation in the
forward jog at set speed mode.
This parameter should be set to a midrange value and then the kick time should be
increased in 0.1 second intervals until the kick is applied long enough to start the
motor rotating when a start is given. If the motor does not start rotating with the set
kick current value then increase the kick current and begin adjusting the kick time
from 0.1 seconds again.
If the motor accelerates to a speed which is greater than the jog speed, then either the
kick current or kick time should be decreased.

NOTE: When DC injection braking is used on a motor, discretion must be used when
setting up the DC braking parameters. Excessive motor heating may result if the load
inertia is large or the brake current or brake time is set too high. In Heavy-Duty
brake applications, caution must be used to assure the motor has the thermal capacity
to brake the desired load, in the desired period of time,without excessive heating.

motor during starting. For a loaded motor, the maximum torque parameter initially
should be set to 100% or greater. If the maximum torque value is set too low, the
motor may not produce enough torque to reach full speed (UTS). On a lightly loaded
motor this parameter may be reduced below 100% to provide for smoother starts.
Ramp Time
Description The ramp time parameter sets the time it takes for the commanded torque to go from
the Initial Torque Setting to the Maximum Torque Setting. To make the motor
accelerate faster, decrease the ramp time. To make the motor accelerate slower,
increase the ramp time.
If the ramp time expires before the motor reaches full speed the starter will maintain
the set Maximum Torque level until either the motor reaches full speed, the stall
(UTS) timer expires, or the motor thermal overload trips.
Note: This ramp time setting is only used for TruTorque starts. It is not the same
ramp time parameter that is used for current ramp profile starts.
Note: Setting the ramp time to a specific value does not necessarily mean that the
motor will take this time to accelerate to full speed. The motor and load may achieve
full speed before the ramp time expires if the application does not require the set
ramp time and maximum torque to reach full speed. Alternatively, the motor and load
may take longer than the set ramp time to achieve full speed.

when the motor winding heater/anti-windmilling brake is enabled.
The motor winding heater/anti-windmilling brake can be used to heat a motor to
prevent internal condensation or it can be used to prevent a motor from rotating.
NOTE: The motor can still slowly creep when the anti-windmilling brake is being
used. If the motor has to be held without rotating, a mechanical means of holding the
motor has to be used.
The motor winding heater/anti-windmilling brake operation has to be enabled by
placing a jumper between terminals 4 and 13 of JC11.
To use the motor winding heater/anti-windmilling brake, apply 120VAC to input
terminal 8 of the JC13 terminal block on the RediStart Micro II computer card and
then give the unit a start command. Instead of starting the motor, the unit will
provide a continuous, low level D.C. current to the motor.
The level of DC current applied to the motor during this operation needs to be
monitored to ensure that the motor isn’t overheated. The current level should be set
as low as possible and then slowly increased over a long period of time. While this is
being done, the temperature of the motor should be monitored to ensure it is not
overheating.

and another motor overload protection device must be supplied.
When the overload is set to bypass (BYP), the electronic overload is disabled during

The starter monitors the instantaneous sum of the three line currents to detect the
ground fault current. This is often referred to as residual ground fault
protection. This type of protection is meant to provide machine ground fault
protection only. It is not meant to provide human ground fault protection.
The ground fault current has to remain above the ground fault level for the ground
delay parameter time before the starter will recognize a ground fault condition. Once
the starter recognizes a ground fault condition, it will shut down the motor and
display a fault 71-Ground Fault. If a programmable relay is set to ground fault (GND),
the starter will energize the relay when the condition exists.
If it is desired to have the starter continue to operate after a ground fault is detected,
enter the fault classes menu (see page 88) and change the classification of fault 71 to
either Dis, WrnA, WrnB, or WrnC.
