  • Page 48: Preparing The Compressed Air

    If possible, operate your system with non−lubricated com pressed air. This will not pollute the environment. Pneumatic valves and actuators from Festo are designed so that, if used as designated, they will not require additional lubrication and will still achieve a long service life.
  • Page 49 Incorrect additional oil and excessive residual oil content in the compressed air will reduce the service life of the valve terminal. Use special oil OFSW−32 from Festo or the alternative oil listed in the Festo catalogue (corresponding to DIN 51524−HLP32, basic viscosity 32 CST at 40 °C).
  • Page 50 A further indication of over−lubrication is the colouring or status of the exhaust silencer. A clearly yellow colouring of the filter element or oil drops on the silencer indicate a too high lubricator setting. 3−6 Festo P.BE−CPA−EN en 0306d...

    Note:By the use of PELV power units, protection against elec tric shock (protection against direct and indirect contact) is guaranteed with Festo valve terminals in accordance with EN 60204−1 / IEC 204. Safety transformers with the adjacent symbol must be used for supplying PELV networks. The valve terminals must be earthed to ensure that they function cor rectly (e.g.
  • Page 67 With this variant of the CPA valve terminal, each valve sole noid coil is connected separately.
