o
"Ramping (l/s/min)":
Increases or decreases the set point over period x when a new set point is entered to help
prevent overshoot or undershoot of the target value. [either by
"Remote Set Point"
Changes or
"Local Set Point"
(override) changes]
Feedback Section:
o
"Source":
Designates which input is to be used as the feedback for the PID loop
o
"Current Value":
Shows the *live* current value of that input
o
"Override":
Allows the user to input an override value from this menu rather than having to go back to the input
information or input configuration screens - this can be helpful when commissioning a system for the first time
C) Output Tab
Input Field Description:
"Output Type":
Designates what type of output is used.
o
"CVM/CVP":
Uses solenoid output (1 or 2) to control the pilot, according to the PID regulation
"Cycle Time (s)":
Designates the total cycle of action for the
"CVM/CVP"
command
o
"Output limit (%)"
: Designates valve opening/closing limit
D) Adjustment Tab
Input Field Description:
"Zone Number":
Designates which PID loop is being adjusted; at any time, up to 4 PID loops may be used
"Closing Speed (%) ":
Designates how quickly the valve will be able to close. 1% is the slowest possible, 99% is the
fastest possible
NOTE:
The actual time to close will depend on the hydraulic conditions.
"Opening Speed (%)":
Designates how quickly the valve will be able to open. 1% is the slowest possible, 99% is the
fastest possible
