Page 9: Function
The modified data are not imported until the vacuum generator is in normal position (vacuum genera- tion and ejector pulse deactivated). Switching functions The binary outputs A and B can be configured via the switching functions. The switching status inform- ation is made available as a process value.

Page 10: Vacuum Generation
Vacuum generation is activated when the output signal (output bit "Vacuum generation") is present for at least 50 ms. Since the vacuum generation is pulse-controlled, vacuum is also generated after deactivation of the output signal. Festo — VABF-S4-...-CB-VH/VL-... — 2019-05... -
Page 11: Valve Control
Destruction of the product due to overpressure If the vacuum connection is tightly closed, overpressure can occur at the vacuum connection and des- troy the pressure sensor. • Use power ejector pulse only in open vacuum systems. Festo — VABF-S4-...-CB-VH/VL-... — 2019-05... -

Page 23: Teach-In Via Fmt
Ä Valve returns to normal position. Teach-in via FMT The teach-in process must be carried out completely via the FMT (Festo Maintenance Tool è www.festo.com/sp). The vacuum generator can store 4 parameter sets. In order to manage additional parameter sets, the individual parameter sets can be stored externally and read in if required. -
Page 24: Teach-In Threshold Value Comparator
7. Set the "Teach-In -> Save" parameter to "active". Ä The teach points are checked for plausibility by the vacuum generator and stored. If the val- ues are not plausible, the data set is deleted and a process warning is triggered. Festo — VABF-S4-...-CB-VH/VL-... — 2019-05... -
