Chicago Pneumatic CPVS 50 Automatic restarting, Remote starting and stopping, Operation, Features

D -Automatic restarting

1 - Description

This management system enables the compressor to be restarted automatically after a power outage.

2 - Option overview

Not available in standard version in order to prevent any incident during maintenance operations carried out by an untrained person. This option is proposed in cases where the production of compressed air should suffer only the minimum periods of shutdowns.

The standard microcut time accepted by AIRLOGIC is approximately : 250 ms.

However, certain electrical fittings create longer micro cut-offs that will cause a compressor shut down, then a manual restart.

Automatic compressor restarting enables immediate air produc- tion after a power outage and thus avoids the time lapse required for manual compressor restarting that would mean a fall in pres- sure in the air circuit.

Particularly used for industries where air production should not be subject to shut downs that waste the products manufactured or damage the production equipment.

RESTRICTED TO TECHNICIANS CERTIFIED BY

CHICAGO PNEUMATIC COMPRESSORS.

AN INFORMATIVE INSERT MUST BE PLACED ON THE ELECTRIC CABINET TO WARN THE USER OF THE RISK THAT THE COMPRESSOR MAY AUTOMATICALLY RESTART AT ANY TIME.

3 - Technical features

This option requires configuration of the electronic plate and installation of an informative insert on the door of the compressor electric cabinet.

Every time the compressor stops, it must be secured by

opening and locking the electric section switch.

E - Remote starting and stopping

This option allows the compressor to be remotely started and stopped. However, in all cases, stopping the compressor at the machine itself is essential. If the compressor is shut down from a distance, it may be restarted from a distance as well. For any intervention to be conducted on the machine, it is essential to activate the emergency stop of the machine in order to ensure safe conditions (Refer to AIRLOGIC Manual, E Section 1)

F - Rotation direction indicator -

Phase controller

1 - Description

The phase controller option is designed to:

-control the rotation direction of the machine's electric power supply phases.

-check that electric power is supplied to each phase.

These two functions are permanently guaranteed.

2 - Option overview

The advantages of this option are:

-starting the machine with the guarantee that it will work (if this option was factory-installed), the configuration of the rotation direction having been configured during the production tests.

-protecting the motor and the electrical fittings from any loss of power supply (phase cuts, blown fuses, voltage threshold lower than 130 volts).

-protecting the machine (motor and especially the compression assembly) when restarting it following electrical work on the power supply line or when switching from the mains supply to a backup power supply, such as a power generator.

3 - Operation

In the event of a phase failure (detectable by this option) or an incorrect rotation direction, the trip switch sets off the machine's safety system (preventing immediate stopping and starting of the machine) and shows the following message on the display of the electronic plate: "ventilation flaw".

4 - Features

scanning time / measurement cycle	< 80 ms
