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.
THIS OPERATION REQUIRES THE CONFIGURATION
OF MENUS IN THE CONTROLLER, ACCESS
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
minimum operating voltage 200 volts
maximum acceptable voltage between phases 600 volts
power consumption 15 VA
