Technical Information
Interconnections
The integrated purge-vent valves (if present on the pump) can be
driven by the controller, in this case use the "purge-vent valves cable"
reported in the "ordrable parts" table.
The Turbo-V 3K-T pump can integrate the purge and vent valves.
The two valves are Normally Closed so if a power fail occur, the
valves will remain closed. The valves operating mode is independent
from the controller operating mode. The valve operating mode can be
set by serial line by win.125 or by front panel using the "program
menu", see following diagram for details. Note that the vent and
purge valve can also be controlled by means of the serial connection
(see the following diagram for details).
