Description
Air drawn through the filter (AF) is compressed in the low-pressure compressor element (El).
The compressed air is discharged to the silencer and intercooler (Ci).
The cooled air is further compressed in the high-pressure compressor element (Eh) and
discharged through the silencer (AS) and aftercooler (Ca).
A check valve (CV) is fitted downstream of the silencer.
The wet air from the aftercooler enters water separator (Ws) via the ejector nozzle. In the
demister (1), the water droplets are removed from the air. The air is then led through the rotor (2),
which adsorbs the water vapor.
The compressed air leaves the compressor via the air outlet (AO).
Description
Two condensate traps are installed:
• one downstream of the intercooler, to prevent condensate from entering the compressor
element
• one downstream of the aftercooler, to prevent condensate from entering the air outlet pipe
A Full-Feature compressor also contains condensate traps downstream of the dryer:
• two traps in case of air-cooled
The condensate traps are connected to an ERD. Refer to Elektronikon regulated drain (ERD )

Reference Description
1 Drain receiver
2 Manual valve
3 Solenoid valve
4 Sensor
Description
The drain consists of a capacitive sensor which is incorporated in the drain collector and of a pilot
valve which is placed outside the drain collector. A drain opening delay timer is started when the
collector is filled up to the level of the capacitive sensor. As long as the delay timer is running,
extra condensate will be collected and the level will rise even higher than the position of the
sensor. As soon as the delay timer has expired, the pilot valve (normally open) is deactivated and
the diaphragm opens the outlet, discharging the condensate. From the moment that the sensor is
not detecting any condensate anymore, a drain closing delay timer is started. The pilot valve will
still drain the condensate during the run of this timer to make sure that the remaining amount of
condensate is drained. The pilot valve is activated when the timer has expired, the outlet closes
quickly without wasting compressed air.

3 Solenoid valve
4 Sensor
9829 5120 36 17
Instruction book
If the controller detects water in the intercooler or aftercooler drain receiver for too long a period,
a shutdown is generated. If water is detected on the integrated dryer drain receiver for too long a
period, a warning is generated.
The level switch is a capacitive sensor which generates a high signal when no water is present.
The solenoid valves of the intercooler and aftercooler/integrated dryer drains are different. The
solenoid valve of the intercooler drain has a high flow but cannot handle high pressures. The
solenoid valve on the aftercooler/integrated dryer drains has less flow but can handle higher
pressures. It is not allowed to open the valves as they can loose their set point. Special attention
must be paid to the correct wiring of the different level switches and solenoid valves.
The output of the level switch can be called up on the screen of the Elektronikon regulator. The
reading does not indicate whether the solenoid valve is open or closed, but indicates whether the
level switch is detecting water in the collector. Since there is a drain opening delay timer, the
display on the Elektronikon can show "Condensate Drain IC Open", while the solenoid valve is
still closed. Changes to the Elektronikon settings are not allowed. The "Always pressurized" bit
must be activated on aftercooler and integrated dryer drains. On the intercooler it is not allowed
to activate this bit.
A functionality test is possible through the Elektronikon regulator. By performing this test, all
solenoid valves will be opened for a short time (e.g. 15 seconds). Refer to the Elektronikon
chapter for more details.

Introduction
The controller has following functions:
• Controlling the unit
• Protecting the unit
• Monitoring components subject to service
• Automatic restart after voltage failure (ARAVF)
A number of time based automatic start/stop commands may be programmed. Take into
account that a start command will be executed (if programmed and activated), even after
manually stopping the unit.
9829 5120 36 25
Instruction book
Shutdown warning
A shutdown warning level is a programmable level below the shutdown level.
If one of the measurements exceeds the programmed shutdown warning level, a message will
appear on the display and the general alarm LED will light up to warn the operator before the
shutdown level is reached.
The message disappears as soon as the warning condition disappears.
When the shutdown warning is shown, press stop button to stop the unit and wait until the unit
has stopped. Switch off the voltage, inspect the unit and remedy if necessary. The warning
message will disappear as soon as the warning condition disappears.
Service warning
A number of service operations are grouped as a Service Plan. Each Service Plan has a
programmed time interval. If the service timer exceeds a programmed value, this will be indicated
on the display to warn the operator to carry out the service actions belonging to that Service Plan.
When the service warning is shown, stop the unit, switch off the voltage and carry out the
required service actions. See section Preventive Maintenance.
If the function is activated and provided the regulator was in the automatic operation
mode, the unit will automatically restart if the supply voltage to the module is restored.
The ARAVF label (see section Pictographs) shall be glued near to the controller.

Electrical connections
To preserve the protection degree of the electric cubicle and to protect its components
from dust from the environment, it is mandatory to use a proper cable gland when
connecting the supply cable to the compressor.
• Obey local regulations if they are stricter than the regulations mentioned in this
document.
• Obey the applicable electrical directives when installing and connecting the
compressor to the power circuit :
• IEC 60204-1
• IEC 60364-5-52
• UL 508 A
• CSA : C22.2
• An isolating switch and the required fuses must be installed before the
compressor. This is indicated on the connection diagram as “customer’s
installation” (customer’s installation).
The fuses protect the supply cables against overload and short circuit. To select
the required type and size of the isolator switch, the fuses and the package current
(found in the technical data sheet) must be taken into account.
• The voltage on the compressor terminals must not deviate more than 10 % of the
nominal voltage. It is however highly recommended to keep the voltage drop over
the supply cables at nominal current below 5 % of the nominal voltage (IEC
60204-1).
• Use the original cable entry. (See section Dimension drawings).
• Full load (compressor) package currents are calculated and available on the
Technical data sheet. For cable section selection purposes, we suggest to add 10
% to compensate for any under-voltages that might occur in the installation.
• Use copper wires only.
• Fuses are maximum allowed values to protect installed compressor electrical
panel, see chapter Circuit breakers and fuses.
• Caution!
• Always double-check the fuse size versus the calculated cable size. If
required, reduce the fuse size or enlarge the cable size.
• Cable length should not exceed the maximum length according to IEC 60204
(table.10).
• Display the fuse type information next to the fuse holder of the mains branch.
• Connect the power cable with the correct cable lugs on the terminals in the
electrical cabinet.
• Do not connect more than one (1) cable lug at one side of a contactor terminal or
copper bar, unless specified otherwise.
Respect a minimum of 10 mm IEC, 1/2” CSA/UL branch circuit between stripped cable
ends for low voltage installations

Warning
Ambient conditions
Refer to Limitations for the limits of ambient conditions and altitude operation. If the compressor
is operated beyond these limits, precautions must be taken. If this is the case, consult your Atlas
Copco Customer Center.
Moving/lifting
In order not to damage the frame, the compressor must be moved either by a lift truck or by using
lifting equipment as described below.
When moving the compressor with a lift truck, use the slots in the frame. Make sure that the forks
protrude from the other side of the frame. When moving the compressor with a lifting device,
insert beams in the slots. Make sure that the beams cannot slide and that they protrude from the
frame equally. The chains must be held parallel to the bodywork by chain spreaders in order not
to damage the compressor. The lifting equipment must be placed in such a way that the
compressor is lifted perpendicularly. Lift gently and avoid twisting.
Attention
General preparations
Make sure the compressor is installed correctly.
See “Electric cables”, “Installation proposal” and “Dimension drawing”.
A sticker summarizing the operating instructions is delivered with the literature set. Affix the
sticker next to the control panel.
A number of VCI (Volatile Corrosion Inhibitor) plates are available inside the bodywork to protect
the compressor against corrosion during transport. Remove these plates.

Step Action
1 Close valves (1, Vd- and Vd+).
2 Open the regeneration air valve (Vr) fully.
3 Open valves (1 and Vd-). Slightly open valve (Vd+) while watching the water levels in
the U-tube.
Two conditions are possible:
• The water level in the leg marked (+) rises. Close valve (Vd+) at once, decrease
the regeneration air inlet pressure (see step 7). Do this as often as necessary, until
the water level drops.
• The water level in the leg marked (-) rises, which should normally be the case. If
the level in this leg rises 30 mm above the level in the leg marked (+), close valve
(Vd+) at once, as there is a risk that the water will be ejected from the U-tube and
disappear into the pressure vessel. Increase the regeneration air inlet pressure
(see step 7) and open valve (Vd+) again.
4 Once the water column has stabilized, adjust the pressure differential as follows:
• Remove the protecting cap from the adjusting screw of throttle valve (Rf).
• Loosen its check nut and turn the screw in to increase or out to decrease the
pressure differential.
• The water level in the leg marked (-) must be between 20 and 40 mm above that in
the leg marked (+).
• Monitor the water level for about 10 minutes.
• Tighten the check nut and reinstall the protection cap.
• Check that the moisture indicator shows blue after approximately 30 minutes of
operation. If the moisture indicator still shows pink after 2 hours of operation, the
pressure dewpoint is too high.
5 Stop the compressor.
