Malfunction Remedy Possible cause
Required vacuum is
not obtained
Insufficient supply of air to the valve
terminal
– Increase supply pressure
– Increase supply cross section
– Install an additional supply plate
directly next to the vacuum
module, optionally create a
separate pressure zone, see
manual VTSA/VTSA-F
Soft-start valve installed on the valve
terminal
If the valve terminal is pressurised,
first send an electrical release
signal (14) to deactivate vacuum
generation. Only revert to vacuum
generation after full operating
pressure of the valve terminal has
built up (12).
Vacuum module does
not revert to the
air-saving function
Insufficient supply of air to the valve
terminal
– Increase supply pressure
– Increase supply cross section
– Install an additional supply plate
directly next to the vacuum
module, optionally create a
separate pressure zone, see
manual VTSA/VTSA-F.
