PID Proportional PID Proportional PID Proportional PID Proportional PID Proportional
This factor determines the strength, or overall
magnitude of change depending on the overall
response of a particular set of system components.
In many cases this value can only be determined
by experimenting and it is well advised to start with
a relatively low number. Too large of a number can
cause oscillations. Normal values are 100 to
1000. For paint applications, a starting value of
150 is recommended.
PID Initial Kick PID Initial Kick PID Initial Kick PID Initial Kick PID Initial Kick
The Initial Kick is beneficial in cases where the
regulator has a large hysteresis. The kick value
will be applied to the analog output if there is a Set
Value present, no fluid flow and the analog output
is less than the kick value. This is programmed in
a range from 0000 to 4095 steps which
corresponds to 0-10 VDC. The correct setting is
that value that will guarantee a minimal flow rate
above the fluid regulator cracking pressure.
PID Tolerance PID Tolerance PID Tolerance PID Tolerance PID Tolerance
This is the margin above and below the Set Point
that determines when the PID pursuit of reaching
the Set Point will be stopped. This window is also
referred to as a “dead band”. Depending on the
mechanics of the system, it is advisable to start
with a large window at first. Then, when system
tuning results in stable operation, this number can
be reduced.
Note that a small value here, will effect the stability
of the “Stable LED” and the Setpoint Achieved
status bit. This value is entered in hundredths of
Hertz. A value of 100 represents 1.00 Hz feedback
from the flow meter. A reasonable setting is 50.
