You start your shift by checking the CMMS and safety board. A conveyor reports a VFD trip—after Lockout/Tagout, you trace the fault with a multimeter and oscilloscope, review the drive’s parameters, and fine-tune settings for stable torque and energy efficiency. Later, you back up a PLC program, make a minor ladder logic tweak to eliminate a nuisance stop, and document the change on the schematic. The afternoon brings scheduled PM: lubricating bearings on a bank of pumps, aligning a motor and coupling, running insulation resistance (megger) and winding checks, and verifying vibration trends. You finish by updating maintenance logs, coordinating with production, and prepping parts for tomorrow’s rotating equipment inspection.
