Pre-Commissioning Start-Up
Trane VFDB MV Drive
Check List
Prior to pre-commissioning start-up, it is imperative for
Rockwell and Trane to receive a completed copy of the
“PowerFlex “A” or “B” Frame Pre-Commissioning Check
List“
as soon as possible. The check list is included at the
end of this manual, and also as a separate form,
AFDJ-AFD001*-EN).
Commissioning
Important:
•
Before servicing, disconnect all power sources and
allow at least 20 minutes for capacitors to discharge.
•
All electrical enclosures-unit or remote-are IP2X.
Start-up Commissioning Services
Start-up will be performed at the customer’s site. Rockwell
Automation requests a minimum of four weeks’ notice to
schedule each start-up. The local Trane office will request
Rockwell start-up upon completion and readiness as per
the pre-commissioning checklist.
The standard Rockwell Automation work hours are
between 8:00 am and 5:00 pm EST (8 h/day) Monday
through Friday, not including observed holidays.
Additional working hours are available on a time and
material basis.
Note:
Do not apply power to the drive prior to Rockwell
site visit. Damages resulting from improper wiring
and power-up will not be covered by warranty.
Drive Commissioning
1. A pre-installation meeting with the customer to
review:
•
The Rockwell automation start-up plan
•
The start-up schedule
•
The drive(s) installation requirements
2. Inspect the drive’s mechanical and electrical devices.
3. Verify internal connections within the drive and verify
wiring.
4. Verify critical mechanical connections for proper
torque requirements.
5. Verify and adjust mechanical interlocks for permanent
location.
6. Confirm all inter-sectional wiring is connected
properly.
7. Re-verify control wiring from any external control
devices.
8. Confirm cooling system is operational.
9. Verification of proper phasing from input voltage
source to drive.
10. Confirm cabling of drive to motor, isolation
transformer, and line feed.
11. Collect test reports indicating megger/hi-pot test has
been performed on line and motor cables.
12. Control power checks to verify all system inputs such
as starts/stops, faults, and other remote inputs.
13. Apply medium voltage to the drive and perform
operational checks.
Note:
At this point, coordinate with Rockwell so that unit
is charged and oil pump is working.
14. Bump motor for rotation check and tune drive to the
system attributes. (If the load is unable to handle any
movement in the reverse direction, the load should be
uncoupled prior to bumping the motor for directional
testing).
15. Run the drive motor system throughout the
operational range to verify proper performance.
Note:
Customer personnel will be required on-site to
participate in the start-up of the system.
16. Log operation of chiller and drive for startup
documentation.
NOTICE
Perform Visual Inspection!
The conditions listed below could cause equipment
damage. Before powering up this drive for the first
time conduct a visual inspection for the following:
•
Shipping damage.
•
Signs of moisture.
•
Signs of debris or dust from storage.
•
Signs of corrosion on components and/or enclosure.
Do not power up equipment if you have concerns
regarding equipment condition. Upon initial power up,
remain in the area for the first two hours of operation
and observe the chiller and drive for any abnormalities.
Contact CenTraVac Technical Support for assistance if
needed.
WARNING
Hazardous Voltage!
Failure to close all enclosure doors and properly secure
with fasteners before operating equipment could result
in death or serious injury due to hazardous voltage.
