27 Description of function Description of function Switch on the FAM at the main switch. After the "Start delay" switch is activated, the inlet valve opens and the vacuum pump builds up the necessary vacuum. This vacuum causes the fluid which is to be purified to be sucked into the vacuum chamber. The fluid to be cleaned trickles downward through special filling materials. These filling materials multiply the surface in the vacuum chamber and make it possible to form a fine fluid film. The fluid collects in the bottom of the vacuum chamber up to the level switch [02]. Then the inlet valve closes, and the evacuation pump conveys the fluid through the fluid filter to the outlet. The filling level in the vacuum chamber drops down to the level switch [01]. Once the level [01] is reached, the 2/2 directional control valve opens, and fluid passes from the inlet through the suction strainer in vacuum chamber until the level switch [02] is reached. The 2/2 directional valve closes and the procedure begins again. The vacuum in the vacuum chamber sucks atmospheric air out through the air filter. This air flows down into the vacuum chamber and is sucked out by the vacuum pump. By virtue of this flow of air, the air picks up the humidity of the fluid. The monitoring of the vacuum pump is limited to the pressure and the temperature. The oil fill level in the vacuum pump is to be monitored by daily visual inspection. The vacuum in the vacuum chamber is set with the throttle valve (vacuum setting). The evacuation pump is protected against dry running by the fill level limit switch in the vacuum chamber. The fill level limit switch switches the electric motor of the evacuation pump off when the vacuum chamber has been emptied. When the "Stop overrun" switch has been pressed, the inlet valve closes and the evacuation pump pumps the vacuum chamber empty. As soon as the light H2 goes out, the FAM can be switched off via the emergency-off switch. When the emergency-off switch has been put into OFF position, the vacuum pump and evacuation pump are switched off. The inlet valve closes under spring force.

29 Using the FAM Using the FAM Bypass purification IN OUT The FAM is connected with suction and pressure lines to the tank and cleans the medium to be found there in continuous operation. Transfer by pumping IN Contaminated oil OUT Clean oil The FAM is connected to the contaminated oil tank by means of a suction line and pumps the fluid into the clean oil tank. However, better purification results are achieved with bypass purification. Therefore, the FAM should be operated after pumping in the bypass flow. To avoid overfilling the purified oil tank, permanently monitor the oil level. HYDAC FILTER SYSTEMS GMBH en(us) Page 29 / 84

30 Explosion protection as per ATEX 95 Explosion protection as per ATEX 95 The water extraction units of the FluidAqua Mobile FAM-ATEX series satisfy all the requirements of the new EU directive 94/9/EC, ATEX 95 applicable to areas in which potentially explosive gas mixtures are likely to occur. The designation of the explosion-proof ATEX-compliant FAM is: II 2G IIB+H 2 T4 (+10 C<Ta<40 C) II 2G IIB+H C (+10 C<Ta<40 C) This means that the FAM may be used only in accordance with: Equipment group II Potentially explosive atmospheres in which vapors or gas/air mixtures are likely to occur. Equipment category 2G Equipment providing for a standard degree of safety. Designated for cases in which atmospheres posing an explosion hazard can be expected to occur very rarely and, if so, only briefly. Explosion hazard subgroup IIB+H 2 Typical gases: Town gas, acrylonitrile, ethylene, ethylene oxide, ethylene glycol, hydrogen sulfide, ammonia, methane, ethane, propane, ethyl alcohol, cyclohexane, n-butane, n-hexane and hydrogen Ensure that vapors, gases or mists occurring at the place of operation belong to explosion groups IIA to IIB. Temperature class T4 Maximum permissible surface temperature: 135 C HYDAC FILTER SYSTEMS GMBH en(us) Page 30 / 84

31 Setting up the FAM Setting up the FAM Observe the following points when setting up the FAM: Place the unit on a horizontal and level surface. Special mounting is not required. Mobile version only - Lock the immobilization brakes on the wheels to avoid unintended movement/rolling away of the unit. Position the FAM in the immediate vicinity of the tank to be cleaned. Observe the maximum permitted suction pressure. See page Fehler! Textmarke nicht definiert.. Observe the ambient temperature on the type label of the FAM. Ensure that the main switch is free and accessible at all times. Keep an area of at least 0.8 m around the FAM free for maintenance purposes. Make sure there is sufficient ventilation around the area where the FAM is set up. CAUTION Outlet air of the vacuum pump Hazardous to health Always make sure there is sufficient ventilation in the surrounding area of the FAM. Air coming out of the vacuum pump can contain particles of vacuum pump oil and/or the fluid. Depending on the composition of the oil and the composition of the gas, there is a danger of damage to health if the emergent gas is inhaled over an extended period of time. HYDAC FILTER SYSTEMS GMBH en(us) Page 31 / 84

32 Connecting the FAM Connecting the FAM All hoses on the FAM must be sufficiently conductive to properly discharge electrostatic charge buildup. If hoses are used, the ohmic resistance between the fittings in this case between the FAM and the tank may not exceed a limit value depending on the respective hose type. Marking the hose with the symbol "M": Limit value 10 2 Marking the hose with the symbol " ": Limit value 10 6 The hose connection must ensure a highly conductive transition between the hose and FAM tube, as well as between the hose and tank tube. If this is not the case, all conducting parts (such as the metal mouth piece at the end of the hose) are to be grounded separately. Connecting conductive hoses with fittings to hose tubes requires marking and checking per DIN EN Connect the ground clamp of the FAM to a suitable grounding source nearby. The grounding lead is 3 m long. HYDAC FILTER SYSTEMS GMBH en(us) Page 32 / 84

33 Connecting the FAM Notes on pipes and hoses In order to keep the pressure loss as low as possible, use as few threaded connections as possible. The pressure differential in a hydraulic line ( P (line) ) depends on the following: Flow rate kinematic viscosity Pipe dimensions Fluid density The pressure loss in straight pipes ( P (line) ) can be calculated as follows: Δp Δp ~ 6,8 * L / d 4 * Q * V * D = Pressure differential in [bar] L d Q V = pipe length [m] = internal pipe diameter [mm] = Flow rate [l/min] = Kinematic viscosity [mm²/s] D = Density [kg/dm³] Mineral oil based hydraulic fluid has a density of ~ 0.9 kg/dm³. This applies to straight pipe runs and hydraulic oils. Additional threaded connections and pipe bends increase the pressure differential. Keep the height difference between the pump and the oil level in the tank as minimal as possible. Hoses must be suitable for suction pressures of at least -0.5 bar. Avoid constrictions in connecting pipelines because they reduce output and increase the risk of cavitation. The nominal size of the connected hoses/piping must be at least as large as the inlet port sizes in order to prevent an excessively high negative suction pressure. HYDAC FILTER SYSTEMS GMBH en(us) Page 33 / 84

34 Connecting the FAM Connecting the suction port NOTICE Overpressure at the suction port connection The unit is damaged The pressure at suction port IN must be in the range from to +2 bar. NOTICE Contamination too high The unit is damaged Do not prime directly at the bottom of the tank Do not prime in the sump The greatest contamination is found on the bottom of the tank. All impurities and other particles are deposited on the bottom of the tank. Make the suction-side connection with a flexible hose that is resistant to negative pressure or with pipelines. The nominal size of the connecting lines must be at least as large as the cross-section of the unit in order to prevent excessively high pressure loss. The suction port must be arranged so that it is always below the oil level. Connecting the pressure port / return-flow line NOTICE Return port connection OUT closed off The unit is damaged Close the return port connection OUT To avoid a concentration of air in the medium, the return-flow line must always be located below the oil level. HYDAC FILTER SYSTEMS GMBH en(us) Page 34 / 84

35 Connecting the FAM Electrical connection of the FAM DANGER Electric shock Danger of fatal injury Any work involving the electrical system may only be done by a properly trained, certified electrician. The voltage and frequency information on the rating plate must coincide with the voltage supply present. If a plug is present on the FAM or if a plug is mounted, then the FAM is to be operated from a correspondingly fused socket. The rotating field of the connection socket must be clockwise. If this is not the case, then the phases can be rotated in the 16A / 32 A connection plug with the aid of the phase changing switch in the plug. For the 63A version, the two phases must be switched on the terminal block S0 (e.g. L1 and L2). A phase sequence relay checks the correct phase sequence after switch-on. In the event of an incorrect phase sequence, error message no. 29 is shown on the control panel. Prior to start up, ground the FAM using equipotential bonding. Prior to starting up the FAM, connect the ground bond to the FAM and the tank to be cleaned. Check the connection between the tank, the FAM and the ground potential for good conductivity.
