6.5 Optional Inlet Valve Control
The control of optional isolation valves is activated on the Master Control by default. If
valves are installed, the system will automatically pilot them.
3 time delays are involved in the control of the function and must be set if inlet valves
are installed. These time delays apply when each PLUS pump in the system is started or
stopped individually.
To set time delays (only available for “Role 2“ people, password required
►
see Role
and User [ ► 6]
):
• Go to “OPERATIONS” > “PARAMETERS”.
• Access to the second screen.

– Time delay before opening valve:
This time delay applies between the time a PLUS pump starts in the system (when one
more pump is needed to reach the Target pressure) and the time the isolation valve in-
stalled upstream of this vacuum pump opens.

PLUS Master Control
– Time delay before closing valve:
This time delay applies between the time the PLUS Master Control sends a signal to take
a PLUS pump out of the system (when it is no longer needed to reach the Target pres-
sure) and the time the isolation valve installed upstream of this vacuum pump closes.
– Additional time delay 2VP -> 1 VP:
This time delay comes in addition to the "Time delay before closing valve". It only ap-
plies when just two PLUS pumps are in operation in the system, to avoid untimely stop /
restart of the second pump in the event that the vacuum requirement is slightly higher
than 100% of the capacity of one vacuum pump alone.
