Function
2.1
Operating mode of the air-saving function (LS)
If the desired threshold value
1
(
è
Fig. 4 “mode of operation air saving function”) is reached for the
vacuum, vacuum generation is automatically switched off. Non-return valves prevent the reduction of
the vacuum. Nonetheless, leakage (e.g. due to rough workpiece surfaces) will slowly reduce the vacu
um. If the pressure drops below the set threshold value
2
, vacuum generation is switched on automat
ically. Vacuum is generated until the set threshold value
1
is reached again.
