4-68 Commissioning
7000L-UM300I-EN-P – June 2013 7000 “C” Frame
Configurable Alarms
Ensure that the configurable alarms have been programmed in the
drive control. Instructions on where to locate the following External
Fault related tasks in the manual are listed below:
• Setting Fault Masks: Chapter 3 – Operator Interface, Fault
Masks. Page 3-42
• Setting External Fault Text: Chapter 3 – Operator Interface,
User Definable External Text 3-45
• Setting Fault Classes: Chapter 4 – Commissioning
The external faults can be tested by lifting the wires to all external
warning / fault inputs while running in system test mode. These
wires are terminated at the Digital I/O boards. Opening the circuit at
any point will verify the external fault‟s configuration and
functionality. However, it is preferable to actually force the trips
from the source. If that is not possible, then an acceptable alternative
is to lift the wire at the protective device.
A T T E N T I O N A T T E N T I O N Do not short the lifted wire to ground when
testing the circuit or damage will occur to the
Digital I/O board and possibly weld the
equipment‟s trip contact.
18-pulse Phasing Test
Prior to applying medium voltage and running the drive, it is
important to verify the phase rotation on the input of all 18-pulse
drives. The following tests do not need to be performed on PWM
rectifier drives unless they incorporate synchronous transfer:
• Line Terminal Resistance Measurements
• Application of Medium Voltage Power
– Compare the voltage feedback from all 9 test points in the
SCB-L to ensure proper phasing.
Failure to perform the recommended tests will result in poor drive
performance and may result in drive converter damage.
