  • Page 7: Counter-Indications

    Any parts or accessories which fail to guarantee safe function are to be replaced. 2. Use only the oils and lubricants recommended or approved by ROTAIR S.p.A. and the engine manufacturer. Ensure that the selected lubricants comply with all current safety provisions, particularly as regards explosion or fire risks, and the hazard of the decomposition or production of harmful gases.
  • Page 8 18. During operations involving either heat, flames or sparks in a machine, the surrounding components must be protected with non-inflammable material. 19. Never use a live flame luminous source to inspect the inside of a machine, pressure container etc. 20. Before dismantling a compressor, engine or other machine or before beginning an overhaul operation ,avoid moving mobile parts weighting over 15 kg.
  • Page 9 -- 5.4) COMPRESSION UNIT AND OIL SEPARATOR TANK -- It is completely manufactured in the ROTAIR S.P.A. factory and consists of a central body (cylinder) inside which are fitted two screw rotors with asymmetric section, a male one with 5 lobes and female one with 6 lobes.
  • Page 10 -- 6. ELECTRONIC CARD DESCRIPTION -- 6.1 General Operation In normal operation, the detected delivery pressure controls regulation of the compressor once the compressor has been started by pushing the start button, or by a remote start command if enabled. The controller will perform safety checks and start the compressor if no inhibiting conditions are detected.
  • Page 11 6.2 Machine State Diagram Controller operational logic is shown in the machine state diagram as state blocks with an associating status block number. The state block determines the functionality of the controller at any given time. The controller can only be in one state at any given time. The controller will move from state to state in accordance with the defined exit and entry conditions of each state block and the defined connections between state blocks.
  • Page 12 Load Delay Timer: The star to delta output transition is immediately followed by a load delay time (adjustable) that will inhibit the load solenoid output from energising until the load delay time expires. Intended to allow the main motor speed to stabilize and other pre-load functions to occur. Reload Delay Timer: The reload delay time (adjustable) is a period of time immediately following a load to unload event during which the load solenoid output is inhibited from energising.

  • Page 26: Maintenance Programme

    -- 11) MAINTENANCE PROGRAMME -- This programme indicates all the necessary periodic operations to be undertaken in the machine and which are essential to ensure its efficient function and long life. ORDINARY MAINTENANCE Can be undertaken by the personnel who operate on the machine and includes all those periodic programmed maintenance operations such as checks on the oil level, air filters, refuelling, cleaning operations and checks to isolate any eventual leakage of lubricant or fuel inside the machine.

  • Page 27: Checking And Maintenance

    Every 2000 HOURS: Cloth replacement in oil separator tank (12.5). Every 3000 HOURS: General check on the various components by the "Authorized Rotair" assistance service. WARNING: during the various maintenance operations it is necessary to carefully examine the rubber piping and should it be found to be excessively hardened and rigid, they must be replaced with materials having equivalent technical features.

  • Page 28: Changing Compressor Oil

    -- 12.1) CHECKING COMPRESSOR OIL LEVEL -- Every morning before starting the machine check the oil level in the compressor tank. The compressor oil level shall never fall below the minimum level notch and never exceed the maximum level either. It shall fall between the two notches of min.

  • Page 30 -- 12.5) FILTERING CLOTH REPLACEMENT IN OIL SEPARATOR TANK -- WARNING! These operations must be undertaken only after having brought the machine to a standstill and disconnected the electricity supply! After checking that the inside of the tank has been fully depressurised, empty out the oil contained inside using the special tap (see paragraph on compressor oil replacement).

  • Page 31: Checking And Setting

    -- 12.6) COOLING RADIATOR CLEANING -- The cooling liquids of the compressor and motor are cooled by a radiator which must therefore be kept clean to ensure that the ventilation air can easily pass through its honeycomb flaps. Should the flaps become clogged with dust of other particles, there is a risk of harmful overheating of the mechanical parts of the screw compressor, seriously jeopardising its function and duration.

  • Page 32: Safety Valve Check

    ROTAIR S.P.A. citing the machine serial number. ROTAIR S.P.A. will not accept any responsibility in the event of the use of non-original and non-conforming valves.

  • Page 33: Air Filter Maintenance

    WARNING: type, density and thickness of the filter have been designed and selected not to brake the sucked in air too much. Therefore the spares shall always be original ROTAIR S.P.A. spares. Should other materials be used the guarantee on the machine will become null and void.
  • Page 34 -- 12.13) TRANSMISSION BELT --- -- 12.13.1) CHECK OF TRANSMISSION BELT TENSIONING --- For normal, efficient compressor functioning the transmission belts must always be perfectly tensioned.. Tensions inferior or superior to those ones we recommend, could cause working anomalies like the sliding or the premature wear and tear of the belt.
  • Page 35 TENSIONING AND REPLACEMENT OF TRANSMISSION BELTS As regards the tension and the replacement of the transmission belts it is necessary to proceed as follows: 1. Loosen the screw (part. A fig 16). 2. Rotate the regulation screw (part. B fig.16) for tensioning.
