Troubleshot VFD 2 PowerFlex 700. Initial start testing showed an overload warning. Checked voltages and confirmed motor
settings. Found phase 1 (brown) was connected to phase 2 (purple) at the motor. Swapped leads in the VFD cabinet. After
swapping leads, the VFD showed a DC Bus voltage error at 705VDC, matching Pump 3 and 4. Worked with tech support for
further testing. Removed motor leads and VFD ran with no faults. Reconnected leads and the same fault occurred. Tech support
suggested a possible motor issue. Rocha planned to escalate the support case for verification since the motor was recently
reworked. Reviewed existing system and requirements with Nate. At RIO2 and the chemical area, the ControlNet rack was
communicating via ControlNet. No panel drawings were available. Upcoming equipment replacements in the area would benefit
from updated drawings. RC requested existing drawings. If unavailable, drawings would need to be recreated, which would be
time-consuming. In the filter area, two control boxes for four filters were scheduled for replacement. RC offered to assist and
provide input. Planned to monitor for related bids. In the Main PLC 2 cabinet, the redundancy module (ControlLogix 5562) was
offline. No drawings were available, and drawings were requested. Wires were running from the control panel to the Nano filter to
bypass a potential conduit issue. Replacement would be quoted after the kickoff meeting. At the I-Well, a meter required
replacement and control panel troubleshooting due to water ingress. Backed up and reviewed PLC and SCADA files. Workstation
1 had an active PLC software license. Backed up all PLC files. Both Workstation 1 and 2 were running GE iFix 5.1. Backed up the
latest revisions. Planned future upgrades for iFix and PLCs, with RC working with Nate on scope, tag count, and estimates.
