Control System - Chicago Pneumatic CPVS 20 Product Description

CONTROL SYSTEM

The AIRLOGIC is an intelligent electronic controller that offers a 4 line x 16 character
digital display and the opportunity to choose 3 of 25 languages. Navigation is simple
and logical which facilitates entry of new parameters and access to compressor
information. This controller has many standard features:
- Weekly programming
- Selection of 2 pressure bands
- Password protection of functional parameters
- Remote control and monitoring
- Running time percentage
- Regulates pressure band within a minimum of 3 psi.
- Manages the reduced voltage "soft" starting transition
- Controls all operations related to the use of the compressor: loading, idling, stop
and restart of the compressor
- Performs the control and the regulation of the machine
- Signals any eventual malfunction in progress
- Stops the compressor due to alarm in progress
- Displays the information on the machine maintenance program
- Networking capability for 4 compressors
The AIRLOGIC has a number of built-in safety features to protect the compressor's
operation:
- Rotation detection
- Air loss detection through oil separator
- Limitation on the number of motor restarts
- Protection against starting under pressure and at low temperature
- Auto restart is not possible after a certain laps of time
- Protection against overpressure in the oil vessel and against high oil temperature
- Test of input/output
- Recording history, up to ten events, of fault parameters that can help a technical
diagnosis
The CHICAGO PNEUMATIC CPVS 40-250 ensures that no energy is wasted by
generating pressure that is not required. The regulation system will automatically
change its method of control as air usage patterns change, ensuring maximum
energy efficiency at all times.
Standard Operating Method
The CHICAGO PNEUMATIC CPVS 40-250 runs in variable speed operation,
unloading when the target pressure is reached and shutting down to save energy
until the cut-in pressure is reached. This kind of regulation is most efficient when air
consumption is variable and includes long periods of low air demand. This system is
based on a load period that will pressurize a receiver tank and then prevents wasted
power consumption while the compressor runs idle until the pressure drops below
the minimum level. The compressor is regulated through a pressure sensor whose
pressure range is set on the AIRLOGIC.
