Checking the setting:
Festo P.BE−VTSA−44−EN en 0905e
Caution
Operation with lubricated compressed air will cause the
life−time lubrication, which is necessary for unlubricated
operation, to be washed out".
Note the following instructions if lubricated compressed air
must be used.
The compressed air prepared with the compressor must
correspond in quality to unlubricated compressed air. If
possible, do not operate all of your equipment with lubricated
compressed air. If possible, always install the lubricators
directly in front of the consuming actuator.
Caution
Incorrect additional oil and too much residual oil content in
the compressed air will reduce the service life of the valve
terminal.
Use Festo special oil OFSW−32 or the other oils listed in
the Festo catalogue (as per DIN 51524−HLP32, basic
viscosity 32 CST at 40 °C).
The additional lubrication must not exceed 25 mg/m
(ISO 8573−1 class 5).
Make sure that the lubricator setting is correct (see fol
lowing section).
This avoids operative malfunction of the valves.
With the machine running (typical operating status) 0.2 to
max. 1 drops/min. or 0.5 to 5 drops/1000 l air.
The procedure described below can be used for checking the
setting of the lubricator.
Proceed as follows:
Check the service units in respect of condensate and
