What it means
The STS controller has not been commissioned for the specific compressor package.
This entry is tied to the exact STS message family documented by Sullair. The same words can mean something different on another controller generation, so confirm the displayed message and machine documentation before acting.
Likely causes
- Controller replacement or initialization without completing package commissioning
Operator-safe first checks
- Record the package model/nameplate information and the message.
- Do not guess configuration values to make the machine run.
Trained maintenance / service checks
- Follow the commissioning procedure for the exact compressor package.
- Verify model, horsepower, pressure, frequency, cooling, starter and other package data before operation.
Reset or keep running?
Do not use repeated resets as a substitute for diagnosis. If the condition involves electrical power, a motor overload, high pressure, loss of cooling, abnormal temperature, or a safety circuit, correct the underlying problem before returning the compressor to service.
