SAFETY INDICATIONS

WHAT TO DO:

Make sure that mains voltage corresponds to the voltage indicated on CE plate and that cable of suitable cross-section are

used for electric connections.

Always check oil level before starting the compressor. Be familiar with emergency stop control and all other controls. Unplug the connector before any maintenance work, so to avoid accidental start. Ensure that all parts have been correctly reassembled after any maintenance work. Keep children and animals off the working area to avoid injuries caused by devices connected to the compressor. Ensure that temperature of the working environment ranges between +5 and + 50 ºC. The compressor should be installed and operated in a non-explosive environment. Allow at least 80 cm between the compressor and the wall so to allow free air flow to the fan. Press the emergency button on the control panel only in case of actual need so as to avoid possible damages to people or

the very compressor.

When calling for technical assistance and/or advice, always mention model and serial number indicated on CE plate. Always follow the maintenance schedule specified in the user’s guide.

WHAT NOT TO DO:

Do not touch inner parts and pipes as they are very hot during compressor operation and stay hot for a certain time after

compressor stops.

Do not position inflammable or nylon objects or cloths close to and onto the compressor. Do not move the compressor when the tank is under pressure. Do not operate the compressor if the power cable is damaged or defective or if connection is unstable. Do not operate the compressor in wet or dusty environments. Never aim the air jet at people or animals. Do not allow unauthorized people to operate the compressor and give them all required instructions. Do not hit fans with blunt objects as they might break during compressor operation. Never operate the compressor without air filter. Do not tamper with safety and adjusting devices. Never operate the compressor when doors/panels are open or removed.

WORKING TIMES

Automatic mode

• The compressor operation is controlled by the pressure switch, which stops the machine when the max. pressure value is reached and starts it again after the pressure has decreased to the min. set value.

• Stoppage of the compressor is delayed; by pressing RESET (2) the compressor begins to operate loadless and stops after 60 seconds. The Standard setting is 60 seconds, but it is recommended to check that number of start-ups per hour does NOT exceed max number of 10. Should it be a higher value, it is recommended to set longer loadless operation time and avoid useless turning on and off cycles.

PRESSURE REGULATOR

The User should install a pressure regulator downstream of the compressor to set the power line according to his/her

needs.

ALARMS

During normal operation of the compressor the following signals can occur:

Alarm warning lights (rif.5, fig.5)

Water in the oil separator tank. Blinking warning light = signal without compressor block Fixed warning light = compressor block Drain the condensate from the oil separator tanks (see chapter “Maintenance”).

The warning light turns on to indicate a wrong electrical connection. The compressor blocks. Check connection to the mains cable and to the terminals of the electrical panel of the compressor. Oil temperature. Blinking warning light = pre-alarm without compressor block Fixed warning light = alarm with compressor block Let the compressor cool down and check the oil level.

The maximum temperature of the motor has been exceeded. The compressor blocks. Let the motor cool down and check setting of thermal relay.

Indicates there has been a blackout. The compressor blocks. With compressor stopped, press RESET to disable the alarm before restarting.

Alarm messages, the following alarms are shown on screen:

AL1 Faulty or broken temperature sensor with blockage of compressor.

Replace sensor.

AL2 Faulty or broken pressure sensor with blockage of compressor.

AL3 No phase or phase sequence transformer not operational with blockage of compressor.

Check presence of phase and if necessary replace transformer.

AL4 Maximum alarm pressure with blockage of compressor.

Contact an assistance centre to remove the cause of the problem.

AL5 Fast rise in temperature with blockage of compressor.

Contact an assistance centre to remove the cause of the problem.

AL6 The emergency button has been pressed.

Reset the button to correct position.

All alarms cause the compressor to block, which can be restarted only when the problem which has caused the blockage

is resolved.

The alarm signal remains even after the problem has been solved, to disable it press the RESET button before restarting

the compressor.

Maintenance signalling The power unit also signals periodic maintenance operations, the internal counters decrease at each hour of loading of the

compressor until zero is reached, at this point the maintenance signal will appear on the display:

START-UP

Before starting the machine for the first time,

check that:

• the mains voltage is the same as the

voltage on the CE plate;

• the electric connections have been made

using cables of proper cross-section,

• the (wall) main power switch has suitable

fuses;

• the oil level is over the minimum level -

top up with the same type of oil if necessary;

CONNECT THE TANK WITH A HOSE.

Only specialised technicians can start the compressor for the first time.

The turning on procedure starts by pressing the START key (1).

The stand-by led (7) blinks and after a few seconds the presence of the phases and their correct sequence is checked,

if the compressor blocks and the warning light turns on the phase sequence device has intervened, press the RESET key (2) and bring the wall switch to OFF position. Open the electric compartment and invert the position of two phases in the power terminal box. Close the electrical compartment and restart.

The start up procedure is repeated: the Screw led (6) blinks and after a few seconds it becomes fixed, the load phase

starts until the “set loadless pressure” value is reached.

The Screw led (6) blinks again and the loadless operation phase begins.

If at the end of the loadless operation (default 75 sec.) the pressure has not fallen below the “set load pressure” value the

compressor stops and the stand-by led turns on (7); otherwise upon reaching the “set load pressure” value the compressor restarts the loading phase and the Screw led turns on in fixed mode (6).

RESET

During routine operation the following information is displayed on screen:

pressure,

temperature,

total hours of operation (with compressor on),

hours of operation loaded (with compressor in load phase).

By pressing the RESET key (2) the turn off procedure starts, the Screw led (6) blinks and the compressor enters the

loadless operation mode for the time set by the parameter “delayed stop time” (default 60 sec.). At the end of the cycle the compressor stops.

OPERATION

SAFETY AND CONTROL DEVICES (fig.5)

1) Pressure switch : regulates STOP and START pressure

2) Safety valve: opens the air drainage to the safety valve.

3) Minimum pressure valve: prevents leakage of compressed air if the pressure is below the

calibration value of the valve

4) Maximum temperature probe:

shuts down motor when 110° is exceeded

OPERATING CYCLE

Cube 5 Direct starting

1) in the first start up the motor starts directly; it reaches

standard speed after 5-7 seconds.

Cube 5- 7-10 Remote starting

1) At first start up the motor starts in the “star” configuration. In this phase the compressor starts slowly, the solenoid (1) is open, and the suction regulator (2) is closed.

The compressor remains in this condition for about 5÷7 seconds, after this time the motor is powered by the “delta” configured circuit.

2) The solenoid valve (1) receives current and closes allowing the opening of the suction regulator (2), which intakes atmospheric air through the filter (3).

3) At this stage, the compressor runs at full speed and begins to compress the air in the tank (6).

4) The compressed air cannot come out from the minimum pressure valve set at 3÷4 bar.

5) The compressed air compresses the oil in the tank (6) and forces it to flow through the filter (8) and pipe (7) to the radiator (9).

6) If the oil temperature is below 80 °C the solenoid valve stays still.

7) If the oil temperature exceeds 80°C the solenoid valve starts operating and cooled oil returns to the compressor through tubes (5).

8) The oil reaches the compressor (4) mixing with the intake air creating an air/oil mixture which ensures the seal and the lubrication of the moving parts of the compressor.

9) The air/oil mixture returns to the tank (6) where the air is pre-separated and later a final separation of the oil takes place, through the oil separator filter (10), and finally it is conveyed to the distribution network.

MAINTENANCE

• Correct maintenance is crucial to achieve maximum efficiency of your compressor, and to lengthen its operating life.

• It is also important to comply with the maintenance intervals recommended, but it must be remembered that such intervals are suggested by the manufacturer in the event that the environmental conditions of use of the compressor are optimal (see “Installation” chapter).

• The maintenance intervals can therefore be reduced depending on the environmental conditions in which the compressor operates.

• The oil used is RotEnergy Plus, the use of a different oil does not guarantee perfect efficiency and compliance with the maintenance intervals.

• The following pages describe the routine maintenance operations which can be performed by the person in charge of the compressor, the non-routine maintenance operations must instead be performed by an authorised technical assistance centre.

MAINTENANCE

DRAIN CONDENSATE

The oil/air mixture cooling is set at a higher temperature with respect to the dew point of the air (under standard operating

conditions of the compressor). However, the condensate in the oil cannot be fully removed.

Blow off compressed air through cock A and then close it as soon as oil begins to flow out instead of water. Check the oil

level and top up if necessary

CONDENSATE IS A POLLUTING MIXTURE! It must not be let into the sewage.

OIL CHECK AND TOP UP IF NECESSARY

Check oil level through the warning light on the left side of the oil separator tank, if the level is below the maximum, top up through union F; before topping up keep fitting H in a vertical position with a key and unscrew plug B to allow the air to exit during the top up.

The quantity of oil required to top up from the minimum to the maximum level is about 0.5 litres.

CLEAN / REPLACE AIR FILTER

Clean the air filter C from the inside towards the outside using compressed air.

Check against the light for possible cuts: replace the filter if any.

The filter cartridge and the cover should be assembled with care, so that no dust goes into the compression unit.

CLEAN RADIATOR

Clean the radiator in case of excessive over temperature and at least once a year.

Proceed as follows:

• Remove the radiator unit and spray (with spray gun + solvent) from the outside towards the inside;

• check for proper air flow through the radiator.

CHANGE OIL

When the compressor temperature is over 70°C change the oil.

• Insert the hose supplied onto cock A.

• Keep the fitting H in a vertical position with a spanner and unscrew the plug B to allow the air to flow out

• Open cock A and allow oil to flow into a collection tray, until complete drainage. Close the cock and remove the hose.

• Remove plug G and pour new oil from union F (quantity to fill up completely: 3.5 litres).

• Close plug B and plug G.

• Power the machine on.

MAINTENANCE

• Start the machine and wait 5 minutes, then stop the machine.

• Blow the air off.

• Wait 5 minutes and check the oil level; top up if necessary.

The oil used is: RotEnergy Plus THE EXHAUSTED OIL IS HIGHLY POLLUTANT! For its disposal comply with the current laws on environmental protection.

CHANGE OIL FILTER

Change oil filter D: this must occur when the tank is not under pressure and without oil. Always apply some oil on the O ring seal of the filter, before refitting it manually.

CHANGE OIL SEPARATOR FILTER

The oil separator filter E cannot be cleaned, but must be replaced.

• Unscrew filter manually (or if necessary use an appropriate filter tool) turning it anticlockwise.

• After having slightly greased the oil separator filter seal and O-ring, fit the new filter by turning clockwise.
