Rockwell Automation 1560E SMC Flex Smart Motor Controller - Manual (Page 80)

3-12 Commissioning Procedures

Table 3.B – Input Voltage Ranges
Tap Voltage Range MV Ratio
D 800 – 1449 V 1020
C 1450 – 2499 V 390
B 2500 – 4799 V 165
A 4800 – 7200 V 105
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 com-
missioning 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.
