72 Rockwell Automation Publication 1560F-UM001A-EN-P - June 2019
Chapter 3 Commissioning Procedure
Programming
SMC-50 Module
Refer to Chapter 4 for programming procedures.
The default (factory) parameter settings are as shown in Appendix A
.
Settings may be different on engineered orders, or when option modules or
customer requirements dictate different settings.
If the factory settings are not suitable for the application, program the module to
meet the application requirements. Contact your local Rockwell Automation
representative or the factory if assistance is required.
Hi-Pot and Insulation
Resistance Test
It is recommended that insulation levels be checked before energizing power
equipment. This may be done with a High Voltage AC insulation tester (HI-
POT) or an insulation resistance test. See publication 1502-UM052
or
publication 1502-UM054
for suggested HI-POT testers, and for test procedures
for vacuum contactors. If using an insulation resistance tester, a 5000V type is
recommended.
Insulation may be tested from phase to phase and phase to ground. The
recommended level for AC HI-POT testing is (2 X VLL) Volts, where VLL is the
rated line-to-line voltage of the power system. The leakage current may be
recorded for future comparison testing, and must be less than 20 mA.
IMPORTANT The module should be programmed with an understanding of how the SMC
functions, and the characteristics of the motor and driven load. Inappropriate
settings may elicit unexpected results such as lack of acceleration torque or
full-voltage starting.
IMPORTANT When SMC-50 module is energized for the very first time, HIM may take couple
of minutes to recognize Medium voltage controller. Once the ID file is
recognized, HIM will display ‘MV Soft Start’
ATTENTION: Solid-state devices can be destroyed by high voltage. Use jumper
wires between heatsinks to short out the SCRs before applying high test
voltages to the power circuit. Disconnect the white wires (L1, T1, L2, T2, L3, T3)
from the voltage sensing board and remove the plug connector. If voltage
transformers are present, remove one primary fuse from each device. On the
1503E, consult OEM documentation for location of voltage sensing board.
ATTENTION: Use caution when performing the HI-POT or insulation resistance
test. High voltage testing is potentially hazardous and may cause severe burns,
injury or death. Where appropriate, the case of the test equipment should be
connected to ground.
