Chapter 5 Preventative Maintenance and Component Replacement
Introduction
The drive can experience reduced service life if operated outside of its design
parameters. Verify that the operating environment is within specifications.
Daily inspection and regular maintenance will maximize the service life of the
equipment.
Daily Inspection
Check the following items during normal operation of the drive:
•
abnormal noise or vibration in the drive or motor
•
abnormal temperature in the drive or motor
•
ambient temperature in the control room above nominal
•
accumulation of dust or particulate on control room floor or surfaces
•
abnormal load current above nominal
Clean the Air Filters
PowerFlex 6000 medium voltage drives require a continuous, smooth airflow
to cool the power components, and the main heating device to ensure the
stable and reliable operation of the equipment. Obstruction of the air filters is
the main cause of poor cooling airflow.
The PowerFlex 6000 drive uses a number of cooling fans that are installed at
the top of the cabinet to ensure that sufficient airflow is used to cool the power
components and other heating equipment. When the equipment is running
for some time, the air filters accumulate dust and obstructs the airflow. Failure
to clean the air filters regularly may result in insufficient cooling airflow,
which may cause some parts of the drive to send an overtemperature alarm or
even trip
(1)
:
•
Transformer overtemperature alarm / trip
•
Power unit overtemperature trip
Immediately after receiving the overtemperature warning, you should plan to
replace or clean the air filters. At this point there should be a few days or weeks
before the air filters fail, but this depends on the amount of dust in the
environment.
Regular Maintenance Intervals
The annual maintenance requirements are summarized on
as a
guideline. Detailed procedures referred to in the
Medium Voltage Motor control equipment should be inspected periodically.
Inspection intervals should be based on environmental and operating
conditions and adjusted as indicated by experience. An initial comprehensive
inspection, within 3 to 4 months after installation, is suggested. See the
following standards for general guidelines for setting-up a periodic
maintenance program.For countries following NEMA standards, refer to
National Electrical Manufacturers Association (NEMA) Standard No. ICS 1.1
(Safety Guidelines for the Application, Installation, and Maintenance of Solid-
Sate Control) for MV Drives and ICS 1.3 (Preventive Maintenance of Industrial
Control and Systems Equipment) for MV Controllers. For countries following
IEC standards, refer to IEC 61800-5-1 Sec. 6.5 for MV Drives and IEC 60470 Sec.
10, IEC 62271-1 Sec. 10.4 for MV Controllers.
(1) Obstruction of the air filters is not the only cause of over temperature alarm and trip.
