Page 7: Characteristics
– Vacuum block supplied with power via separate M12 plug connector, not via the valve terminal – The vacuum block VABF-S4-1-V2B1 can be operated in combination with the vertical stacking for pilot air switch-off (intermediate plate VABF-S4-1-S plus 5/2-way valve) on the valve terminal VTSA. Festo – VABF-S4-1-V2B1... – 1705c English... -
Page 8: Operating Statuses Of The Vacuum Block
Operating statuses of the vacuum block If the pilot air supply or the electrical supply of the vacuum block is switched off, the respective operat ing status is changed as follows (è Tab. 2). Festo – VABF-S4-1-V2B1... – 1705c English... -
Page 9: Electrical And Pneumatic Status Changes
• Failure of the valve terminal electrical supply: – The switching position of the valve can only be changed through the electronics of the vacuum block (change between “Generate vacuum” and “Air saving”). Festo – VABF-S4-1-V2B1... – 1705c English... -
Page 10: Function And Application
The length of the ejector pulse can be influenced by the duration of the electrical pulse. The strength of the ejector pulse is influenced by the adjustable flow control valve. Festo – VABF-S4-1-V2B1... – 1705c English... -

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. Festo – VABF-S4-1-V2B1... – 1705c English... - Page 12 Mode of operation of the air-saving function Vacuum generation is switched off as soon as the vacuum is higher than threshold 1 and is switched on again as soon as the vacuum is less than threshold 2.

3 (è Fig. 5 “Installation”). The maximum vacuum that can be generated depends on the operating pressure. Note The required vacuum may not be generated if there is an insufficient supply of air to the valve terminal. Festo – VABF-S4-1-V2B1... – 1705c English... - Page 18 The flow resistance in large suction cups can result in a device-independent build-up of a vacuum that delays the release of the suction cup from the workpiece. • Make sure the ejector pulse is active until the end of the suction cup’s releasing procedure.
