NOTE:
Actual time to open will depend on the hydraulic conditions.
"Deadband (l/s)":
Designates where the controller will take no action because it is close to the SetPoint.
Example: If the setpoint is 50 l/s and the deadband is set at 2 l/s, then the controller will take no action on
the feedback value from 48 l/s to 52 l/s
"Integral (s)":
This value is used for fine tuning of very sensitive systems
It is not recommended that this be used without contacting CLA-VAL Technical Support!
"Derivative (s)":
This value is used for fine tuning of very sensitive systems
It is not recommended that this be used without contacting CLA-VAL Technical Support!
E) Zoning Tab
Input Field Description:
"Number of zones":
Designates how many PID zones are to be created
NOTE:
When multiple PID loops are created, the active region for each is designated by an equal division of the
total feedback range, see example below:
The active region for zones 1, 2 and 3 are each one third of the total feedback range. These values can be specified by
changing the values in each zone, according to the needs of the user.
Zone 1: designates the top of the range for zone 1 (bottom range is bounded by the low level of the feedback scale).
Zone 2: designates the bottom and top range for zone 2.
Zone 3: designates the bottom range for zone 3 (top of the range is bounded by the high level of the feedback scale).
