Controls, VFDs & System Troubleshooting
Controls-focused troubleshooting for unstable pressure, VFD hunting, staging issues, alarms, and sensor-related problems.
How RMS Approaches It
Diagnosis before replacement.
A healthy pump can still perform poorly when control signals, setpoints, sensors, check valves, or staging logic are unstable.
Typical service scope
- VFD command and feedback review
- Pressure transducer, lead-lag, staging, alarm, and control-sequence checks
- Mechanical verification where controls symptoms may be system-side
- Final setpoint and operating observations for maintenance reference

Preventative Maintenance ProgramsRepeatable maintenance observations that help agencies and facilities identify change before it becomes an emergency.
Common Failure Conditions
Symptoms RMS evaluates before recommending a repair path.
The goal is to identify whether the issue is hydraulic, mechanical, electrical, controls-related, or a combination of conditions affecting the complete pumping system.
Typical indicators
- VFD hunting, nuisance faults, unstable commands, or feedback mismatch
- Lead-lag sequencing problems, staging issues, or alarm behavior
- Pressure, level, sensor, or transducer signals that do not match field condition
- Pump packages that look mechanical but are being driven by controls symptoms
- Control settings that no longer match actual system requirements
RMS Process
From first symptom to documented return-to-service.
RMS follows a practical workflow: understand the operating problem, verify the cause, perform the right work, test the result, and leave a usable service record.
Assessment
Collect symptoms, site context, equipment details, and urgency before assuming the pump is the only fault.
Diagnosis
Compare operating observations, current, pressure, flow, controls behavior, valves, and mechanical condition.
Recommendation
Separate confirmed repair needs from system-side issues and identify the practical return-to-service path.
Repair
Complete field service, shop repair, rebuild coordination, controls adjustments, or retrofit work within RMS's scope.
Testing
Verify rotation, pressure, drawdown, sequencing, leakage, vibration, current draw, and system behavior where applicable.
Documentation
Record post-service observations so future maintenance and troubleshooting have a usable baseline.
