INSTALLATION, OPERATIONS AND MAINTENANCE MANUAL 13
Automatic racking
Automatic Racking is the device’s standard
operating mode. It allows the operator to specify a
starting position and an end position. The device
processes this information and then performs the
complete racking procedure.
Once Automatic Racking has been selected, the
select initial position screen (Figure 24) will request
the current position. Connect is when the unit is all
the way forward into the frame and both primary
and secondary connections are made. Disconnect
is when the unit is all the way backward where
neither the primary nor secondary connections are
made. Test is between disconnect and connect
where only the secondary connections are made.
Connect, Test, and Disconnect may be selected by
pressing function buttons F1, F2, and F3,
respectively. The ReliaGear ND platform will only
have Disconnect and Connect positions for the
circuit breaker.
Note that the Test option may not be available for
some devices, like potential transformers which
have no test position on the racking screw.
Once a start position has been selected, the text
for that position will be highlighted. Confirm the
selection by pressing the ENTER button. Always be
sure to double check the entered initial position
matches the actual position of the unit.
In the main menu screen, (Figure 23) the operator
can select either F1 for automatic racking, F2 to
change the unit type or F3 for manual racking.
Automatic racking should be used whenever
possible since it is intended to move devices
between positions. Manual Racking gives the user
greater control over the operation of the racking
device; however, should only be used in exceptional
circumstances, such as when a breaker failed to
completely rack to a position. Refer to Section
Automatic Racking or Section Manual Racking for
more detail on the racking process.

Once an initial position has been entered, the
device will display a screen to select the final
position (Figure 25). Note that some options, like
the selected initial position, will be unavailable.
Similar to the previous menu, the final end position
will be highlighted and must be confirmed by
pressing enter.
At this point SmartRack™ MV is ready to start the
Automatic Racking sequence. The program tells the
motor to torque to one side and then the other side
and then moves to the center of the hole as a
calibration of the breaker or other unit. If the unit is not
in a positive position such as Disconnect, Test, or
Connect, then SmartRack™ MV will not be able to
calibrate and a centering error will be displayed. Please
remove the motor and ensure that the unit is in a
positive position with the position interlock in place.
After initialization, the position interlock is
actuated. The operator can begin by pressing the
GO button. The operator can monitor racking
progress through the Automatic Racking screen
(Figure 26). The Automatic Racking screen displays the
device status and shows the relative position of the
unit inside the cell using an incremental status bar.
When SmartRack™ MV reaches 90% of its
calculated travel (i.e. from connect to test), the
position interlock is released. As the final 10% of
travel is completed, the position interlock should
make an audible click as it locks into the position.
Once SmartRack™ MV completes an automatic
position move, a racking complete screen (Figure 27)
appears showing the new current position of the unit.
Press the F1 button to move to a new position, or
BACK to return to the main menu.
Notice: After operating SmartRack™
MV in an automatic or manual move of
contactor, verify that the unit is in the
desired position visually or manually
through use of a racking handle before
operating unit.
Manual racking
Manual racking allows the operator greater control
over the unit as compared to Automatic Racking.
Rather than the device performing all the steps in the
racking process, the operator is responsible for
starting and stopping the unit being racked.

NOTICE

INSTALLATION, OPERATIONS AND MAINTENANCE MANUAL 15
Manual racking is not unit-specific. Initial and final
positions are not required for operation, although
other settings such as torque limit, velocity and the
existence of an interlock are unit specific; therefore,
considerable caution is required when using
SmartRack™ MV in manual mode.
If selected from the Main Menu, the racking device
goes directly to the Manual Racking screen (Figure 28)
and applies power to the Motor Box.
Once the Motor Box is secured to the cell door, the
operator should take the hand-held Control Box and
move a distance away as defined by their local
procedures. At this point SmartRack™ MV is ready to
start Manual Racking. This setting utilizes the three
buttons to the lower left of the screen (Figure 29).
The IN button moves the unit towards the contacts and
the OUT button moves the unit towards the door. These
buttons must be pushed and held to produce motion.
Releasing the button will cause the unit to come to a
stop. The button with a picture of a pad lock toggles the
interlock. In an emergency situation, the red STOP
button can be pressed to send a stop command to the
servomotor and cut power to the Motor Box.
Indicator lights
While SmartRack™ MV is in operation, the indicator
light on the motor box will change from green to
yellow. When racking is complete the indicator light
will return to green. The indicator color significance is
listed in table 2.
Racking complete
When either Automatic or Manual Racking is complete,
press the BACK button to return to the main menu. From
here racking can be repeated using the process explained
earlier in this section. Otherwise, return the hand-held
control to its place on the cart and detach the Motor Box
from the door by twisting the rotary latches on both
sides. Return the Motor Box to its area on the cart and
follow the instructions in Section Storing the Device.
Always ensure that the unit is completely racked to
the desired position and that the interlock pin has
dropped into its slot in the racking screw, if applicable,
before continuing.
