Compressor

Interfaces

This section covers the compressor interfaces. The operation of the compressor varies
based on the model. The Scott models use a HMI to operate the compressor. See

“Configuration and Setup” on page 21.

Other models do provide analog gauges, but

do not provide a touch pad controller.

Warning: When settings are changed, ensure those changes are communicated to all
affected personnel.

Depending on the configuration, the compressor may be controlled via the HMI. In
general, the HMI is used to start and stop the compressor and to provide information
about the compressors’ operation, performance and conditions to the operator.

shows an example of a compressor screen.

Compressor Screen Example

Compressor Process

This section provides a general overview of the compressor process, as each model
varies.

Warning: Never leave the Stationary Air Compressor system unattended while the
compressor is in use. A Scott trained and certified operator must monitor the system
gauges at all times and take immediate action to guard against equipment failure. This
equipment is intended for providing breathable air to save lives. Failure to monitor
the system may lead to permanent equipment damage, serious personal injury or
death.

Warning: Hearing protection may be required when using the Stationary Air
Compressor system for extended periods of time. Refer to the personal safety
