SAFETY PRECAUTIONS

To be read attentively and acted accordingly before installing, operating or repairing the unit.

These recommendations apply to machinery processing or consuming air or inert gas. Processing of any other gas requires

additional safety precautions typical to the application which are not included herein.

If necessary, install a suction duct. Never obstruct the air inlet. Care
shall be taken to minimize the entry of moisture with the inlet air.

4. The aspirated air shall be free from flammable fumes or vapours,
e.g. paint solvents, that can lead to internal fire or explosion.

5. Air-cooled units shall be installed in such a way that an adequate
flow of cooling air is available and that the exhausted air does not
recirculate to the inlet.

6. Arrange the air intake so that loose clothing of people cannot be
sucked in.

7. Ensure that the discharge pipe from the compressor to the aftercooler,
air dryer or air net is free to expand under heat and that it is not in
contact with or close to flammable material.

8. No external force may be exerted on the air outlet valve; the connected
pipe must be free of strain.

9. If remote control is installed, the unit shall bear an obvious sign
reading:

DANGER: This machine is remotely controlled and may start
without warning.

As a further safeguard, persons switching on remotely controlled
units shall take adequate precautions to ensure that there is no one
checking or working on the machine. To this end, a suitable notice
shall be affixed to the start equipment.

10. On units with automatic start-stop system, a sign stating "This
machine may start without warning" shall be attached near the
instrument panel.

11. In multiple compressor systems manual valves shall be installed to
isolate each compressor. Non-return valves (check valves) shall not
be relied upon for isolating pressure systems.

12. Never remove or tamper with the safety devices, guards or insulations
fitted on the unit. Every pressure vessel or auxiliary installed outside
the unit to contain air above atmospheric pressure shall be protected
by a pressure-relieving device or devices as required.

13. Pipework or other parts with a temperature in excess of 80 degrees
celsius and which may be accidentally touched by personnel in nor­mal operation shall be guarded or insulated. Other high-temperature
pipework shall be clearly marked.

OWNERSHIP DATA

In addition to normal safety rules which should be observed with stationary
air compressors and equipment, the following safety directions and
precautions are of special importance.

When operating this unit, the operator must employ safe working practices
and observe all related local work safety requirements and ordinances.

The owner is responsible for maintaining the unit in a safe operating
condition. Parts and accessories shall be replaced if unsuitable for safe
operation.

Installation, operation, maintenance and repair shall only be performed
by authorized, trained, competent personnel.

Normal ratings (pressures, temperatures, time settings, etc.) shall be
durably marked.

Any modification on the compressor or air dryer shall only be performed
in agreement with Atlas Copco and under supervision of authorized,
competent personnel.

If any statement in this book, especially with regard to safety, does not
comply with local legislation, the stricter of the two shall apply.

These precautions are general and cover several machine types and
equipment; hence some statements may not apply to the unit(s) described
in this book.

Installation

Apart from general engineering practice in conformity with the local
safety regulations, the following directives are specially stressed:

1. A compressor or air dryer shall be lifted only with adequate equipment
in conformity with local safety rules.

Loose or pivoting parts shall be securely fastened before lifting. It is
strictly forbidden to dwell or stay in the risk zone under a lifted load.
Lifting acceleration and retardation shall be kept within safe limits.

Wear a safety helmet when working in the area of overhead or lifting
equipment.

2. Any blanking flanges, plugs, caps and desiccant bags shall be
removed before connecting up the pipes. Distribution pipes and
connections shall be of correct size and suitable for the working
pressure.

3. Place the unit where the ambient air is as cool and clean as possible.

1.3 Automatic restart after voltage failure

For compressors leaving the factory, this function is made
inactive. If desired, the function can be activated. Consult
Atlas Copco.

Warning If activated and provided the module was in the

automatic operation mode, the compressor will
automatically restart if the supply voltage to the
module is restored.

Ref. Designation Function

1 Stop button Push button to stop the

compressor. LED (10) goes out.
The compressor will stop after
running in unloaded condition for
about 30 seconds.

2 Start button Push button to start the

compressor. LED (10) lights up
indicating that the regulator is
operative (in automatic operation).

3 Display Indicates the compressor operating

condition, measured values and
programmed parameters.

1 General description

1.1 Automatic control of the compressor

The regulator maintains the net pressure between programmable
limits by automatically loading and unloading the compressor.
A number of programmable settings, e.g. the unloading and
loading pressures, the minimum stop time and the maximum
number of motor starts are taken into account.

The regulator stops the compressor whenever possible to reduce
the power consumption and restarts it automatically when the
net pressure decreases.

1.2 Protecting the compressor

Shut-down

If the compressor element outlet temperature exceeds the
programmed shut-down level, the compressor will be stopped.
This will be indicated on display (3). The compressor will
also be stopped in case of overload of drive motor (M1) and,
for air-cooled compressors, also the fan motor (M2).

Shut-down warning

If the compressor element outlet temperature or dewpoint
temperature (Full-Feature compressors) exceeds a programmed
value below the shut-down level, this will also be indicated to
warn the operator before the shut-down level is reached.

Service warning

If the service timer exceeds a programmed value, this will be
indicated on display (3) to warn the operator to carry out some
service actions.

compressor element is 122 °C.

4. Switch off the voltage and remedy the trouble.

5. After remedying and when the shut-down condition has
disappeared, switch on the voltage and restart the
compressor.

5.2 Motor overload

1. In case of motor overload, the compressor will be shut down,

6 Service warning

A service warning will appear when the service timer has
reached the programmed time interval.

1. In case the service timer exceeds the programmed time
interval, alarm LED (8) will light up.

2. Press arrow key (12): r000 is shown (register 000).
Press enter key (5), S (S standing for Service)
appears. Use key (12) to scroll to r005 (register 005)
and press enter key (5), the actual reading of the service
timer will be shown in kHrs (hours x 1000) .

Example: 4.002 indicates that the compressor has run for
4002 hours since previous service.

3. Press enter key (5) and key (12) to scroll to r001
(register 001). Press key (5) to check the running hours,
which are shown in kHrs (hours x 1000).

Example of running hours screen:

kHrs

8.000

The screen shows that the number of running hours is 8000.

4. Stop the compressor, switch off the voltage and carry
out the service actions as explained in the maintenance
schedule in the related Instruction book.

Important

- The longer interval service actions must include the
shorter interval actions.
In the example above, carry out all service operations
belonging to the 8000 running hours interval as well as
those belonging to the 4000 running hours interval.

- If using mineral oil instead of Atlas Copco Roto­injectfluid, the service timer interval has to be decreased:
500 running hours for 13 bar (175 psi) units and 1000
running hours for 7.5-10 bar (100-150 psi) units.

5. After servicing, reset the service timer (see section 7.5).

7 Scrolling through all screens

Scroll keys (12 and 13) can be used to scroll through all screens.
The screens are divided in register screens (numbered as r001,
r002,...) and parameter screens (numbered as P001,
P002,...).
During scrolling, the numbers of the screens appear consecutively.
For most screens, the unit of measurement and the related
pictograph are shown together with the screen number.
In case of a warning or shut-down, an extra register screen (r000)
is accessible.

Example:

kHrs
r001

The screen shows the screen number (r001), the unit used (kHrs
or hours x 1000) and the related pictograph for running hours.
Press enter key (5) to call up the actual running hours.
