Operational Inspection—Power
Applied
1. Verify the drive cabinet cooling fans are operating.
This should be done from outside the enclosure, by
looking into the cabinet at door and cabinet vents, to
avoid electrical hazards.
Note: The power module fan comes on with power.
Other fans cycle with drive operation.
2. Check historic fault codes using OIM connected to the
AFD.
3. Check configuration settings and confirm all proper
settings are still present in the controls.
4. Review the diagnostic history.
5. Make Chiller Service report to document all setpoints.
6. Check the UC800 alarm histories for any indications of
operational problems.
Do this every 1–12 months depending on
operating environment
To properly diagnose service issues for Adaptive
Frequency drives for centrifugal chillers equipped with
LF 2.0 (AFDE) starters, and Operator Interface Module
(OIM) and special cable are required. All UC800 chillers
will be equipped with the OIM as standard on the drive
power module. This is for service only and NEVER for
machine operation. These items are available from Trane
with the following part numbers:
OIM (Operator Interface Module): MOD01352
Cable for OIM: CAB01034
Do as needed
Replace the magnetic choke if there is physical damage
(for example, cracks).
Chiller Operator Display Content
Refer to Operations Guide: Tracer AdaptiView Display for
Water-Cooled CenTraVac Chillers (CTV-SVU01*-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; Tracer
AdaptiView kW is communicated from the
drive to the chiller panel, and represents
input power to the drive.
