Example
: if the cycle time is 10 minutes and a control value of 20% is
received, then (every ten minutes):
The valve will remain open for 2 minutes.
Afterwards it will remain closed for 8 minutes.
Opening Minimum Value
[
0
…100
][
%
]
:
minimum value from which the
output will start to regulate.
Note:
Even if the control orders come from an alarm, lock, etc., the
minimum value criterion will also be applied, so it is recommended not
to set fixed regulation values below the minimum in these functionalities.
Example
: assuming an
opening minimum value of 20%
, the final
status of the valve at the following control orders will be as follows:
Valve = 0%
control order = 10%
Valve = 0%.
Valve = 30%
control order = 10%
Valve = 20%.
Valve = 0%
alarm with action = 15%
Valve = 0%.
Valve = 50%
alarm with action = 15%
Valve = 20%
Value for Open Valve
[
1
/ 0
]: sets the control value to open the valve. The
polarity will also affect the status object of both control methods (1 bit and 1
byte).
Valve type
[
Normally Closed
/ Normally Open
].
Note
:
the control value to close a valve
is “0” or “1” (under a one-bit control),
as the previous parameter is configured, or always
“0%” (under a 1-byte
control) no matter if the valve is normally open or normally closed. See Table
1 for details.
Count with this output to:
Notify That All Valves Are Closed
[
disabled/
enabled
]: when checked, the
current output will be taken into account to determine whether all valves are
closed or not.
