The set point output stays open until the frequency becomes higher
than 505 Hz (that is 500 Hz + 1% of 500 Hz), then the output goes
closed and stays colsed until the frequency becomes lower than 495
Hz (that is 500 Hz – 1% of 500 Hz).
It is possible to mask the set point checking for a programmable mask
time (window 103).
The set point signal has the following default settings:

PURGE/VENT VALVES: the Turbo-V 3K-G pumping system
integrates 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. That means the user can manage the pump by serial
line (start/stop, soft start...) and drive the valves by remote I/O
connector, or vice versa. The valve operating mode can be set by
serial line with win.125 and 146, see following diagram for details.
