Maintenance
54 AFDJ-SVU01D-EN
– Clean all contaminated components using a
vacuum cleaner (DO NOT use a blower), and wipe
clean components where appropriate.
• Check for any visual/physical evidence of
damage and/or degradation of components
in the
medium voltage compartments (inverter/rectifier,
cabling, DC Link, contactor, load break, harmonic filter,
etc).
– This includes main cooling fan, power devices,
heatsinks, circuit boards, insulators, cables,
capacitors, resistors, current transformers,
potential transformers, fuses, wiring, etc.; Causes
could be corrosion, excessive temperature, or
contamination.
– Verify torque on heatsink bolts (electrical
connections to bullet assemblies) is within
specifications (13.5 N·m).
– Clean all contaminated components using a
vacuum cleaner (DO NOT use a blower), and wipe
clean components where appropriate.
Note: An important component to check for
contamination is the heatsink. The fine
grooves in the aluminum heatsinks can
capture dust and debris.
– Carry out the physical inspection and
verification for the proper operation of the
contactor/isolator interlocks, and door
interlocks.
– Carry out the physical inspection and verification
for the proper operation of the key interlocks.
– Carry out the cleaning of the fans and ensure that
the ventilation passages are not blocked and the
impellers are freely rotating without any
obstruction.
– Carry out the insulation meggering of the drive,
motor, isolation transformer/line reactor, and the
associated cabling.
– Check clamp head indicator washers for proper
clamp pressure, and adjust as necessary.
Control Power Checks (No Medium Voltage)
Important:
• Before servicing, disconnect all power sources and
allow at least 40 minutes for capacitors to discharge.
• All electrical enclosures-unit or remote-are IP2X.
• Apply Control power to the PowerFlex drive, and test
power to all of the vacuum contactors (input, output,
and bypass) in the system, verifying all contactors can
close and seal in.
• Verify all single-phase cooling fans for operation.
• This includes the cooling fans in the AC/DC Power
supplies and the DC/DC converter.
• Verify the proper voltage levels at the CPT (if installed),
AC/DC Power Supplies, DC/DC converter, isolated gate
power supply boards.
• Verify the proper gate pulse patterns using Gate Test
Operating Mode.
• If there have been any changes to the system during
the outage, place the drive in System Test Operating
Mode and verify all functional changes.
Final Power Checks Before Restarting
• Ensure all cabinets are cleared of tools, and all
component connections are back in place and in the
running state.
• Put all equipment in the normal operating mode, and
apply medium voltage.
• If there were any input or output cables removed,
verify the input phasing, and bump the motor for
rotation.
• If there were any changes to the motor, input
transformer, or associated cabling, you will have to
retune the drive to the new configuration using
autotuning.
• Save all parameter changes (if any) to NVRAM.
• Run the application up to full speed/full load, or to
customer satisfaction.
• Capture the drive variables while running, in the
highest access level if possible.
Chiller Operator Display Content
Refer to Operations Guide: Tracer AdaptiView™ Display
for Water-Cooled CenTraVac™ Chillers (CTV-SVU01C-EN,
or the most recent version) for Tracer AdaptiView display
information.
Important: Please note that the Tracer AdaptiView
displayed voltage is
line side input
voltage , whereas current and power factor
are load side data . Therefore, these are
not used together to calculate kW.
WARNING
Live Electrical Components!
Failure to follow all electrical safety precautions when
exposed to live electrical components could result in
death or serious injury. During installation, testing,
servicing and troubleshooting of this product, it may be
necessary to work with live electrical components.
When necessary to work with live electrical
components, have a qualified licensed electrician or
other individual who has been properly trained in
handling live electrical components perform these
tasks.
