D -Automatic restarting

1 - Description
This management system enables the compressor to be restarted
automatically after a power cut.
2 - Option overview
Not available in standard version in order to prevent any incident during
maintenance operations carried out by a non-trained person. This op-
tion 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 : 40 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 cut and thus avoids the time lapse required for
manual compressor restarting that would mean a fall in pressure
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 CONFIGURA-
TION 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 controler 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 in-
tervention to be conducted on the machine, it is essential to activate
the emergency stop of the machine in order to ensure safe condi-
tions (Refer to AIRLOGIC Manual)

F - Special oils

1 - Description
Different oils meet different needs:
Rotair Xtra: longer time interval between 2 drainage operations -
8000 hours (use of special oil filters).
Food Grade Oil: use of the compressor in the agricultural foodstuffs
industry.

Note: if this option is chosen on a machine that has previously
run on standard oil, the flushing procedure must first be strictly
complied with.
2 - Description of the option
Rotair Xtra
The properties of these oils enable the maintenance planning
schedule to be based on main drainage operations of 4000 or
8000 hours (under standard conditions of use).
The maintenance tasks are consequently less frequent, thus making
for certain savings, such as the availability of the equipment and
lower operating cost of the compressor.
Food Grade Oil
This oil has been specially developed for use as a lubricant that
may come into contact with foodstuffs.
G - Centrifugal separator
(see B chapter 1)
Fig. 17
1 - Description
This device allows bleeding of the condensates formed in the air
cooler.
2 - Description of the option
The cooling of the compressed air allows the suction air to be
dried, thus removing the humidity that collects in the bottom of
the separator after being condensed in the aftercooler. The
condensates are evacuated from the separator through a trap with
a solenoid drip valve or a trap with level detector if this option is
installed.

H - Condensate drain pipes

A separator with automatic solenoid valve drain is provided
inside the set ( see Chapter 5-K) to remove the condensate at
the final cooler outlet and stop the compressor pipe condensate
return lines. Connect the discharge pipe to a condensate
manifold.(see B chapter 1)
