Commissioning Procedure

Chapter 3

Software will be used to scale the output to show the correct value on the SMC
Flex front panel display. (See Parameter #106 –

MV Ratio)

Table 4 - Input Voltage Ranges

The MV ratios shown above are nominal values and may be fine tuned to achieve
better accuracy on the display of the SMC Flex control module. While running
the motor in bypass mode, compare the voltage displayed on the control module
to a known accurate meter connected to the same source voltage as the motor the
MV SMC Flex is controlling. Parameter 106,

MV Ratio, may be changed up or

down to match the Flex display to the external meter. A small change in ratio can
make a large change in the display, so 5 units at a time is recommended.
Increasing the ratio will decrease the displayed voltage, and visa versa.

Start-Up

1.

Remove any temporary jumpers or grounding devices used during
commissioning.

2.

Check that all tools are removed from the equipment. Any tools or
hardware used or dropped during installation and commissioning must be
retrieved and accounted for.

3.

Check that all barriers or covers removed during installation or
commissioning have been securely mounted.

4.

Close and secure all doors, and verify function of all interlocks that
prevent access to medium voltage compartments when the unit is
energized.

5.

The controller is ready to power the motor.
