Zero/Span Input 3 Range Jumper
Zero/Span Output 1
Zero/Span Output 2
Note – On the zero/span input screens, the range listed next to the input will depend on the input
type set up in the
Analog Input Setup
menu option
.
The
Calibration
screen for the Full Calibration menu option also has a Set Nominal button, which
will set nominal values for the current screen. The user will have to confirm the action.
Clicking on the Yes button will set the nominal values, and clicking on the No button will cancel
the action.
Click the Done button to close the screen down.
Alternate PID Setup
The Alternate PID Setup menu option
allows for up to 16 sets of PID values to
be used on all three loops via the
programmer.
This menu option is typically used for
vacuum applications with the
programmer.
There is a choice of PID 1 – 16, and LP1
Set 1 – LP3 Set 3.
Prop Band (0 for On/Off)
This is the proportional band field. This
represents the P in PID. P =
Proportional. This is a field in which you want the process variable to stay around the setpoint.
Clicking on the value will allow the user to change the value
.
The range of values is –1.0 to
999.0.
Reset
This is the reset field. This represents the I in PID. I = Integral. This is the actual temperature
being monitored over a period of time and then averaged to keep within the Proportional band.
The reset is in repeats per minute. This helps to eliminate offset.
The range is 0.00 through
10.00.
Rate
This is the rate field. This represents the D in PID. D = Derivative. This is the sudden change or
rate in the temperature. This rate is in minutes. This affects the controller output which is
proportional to the rate of change of the measurement and will control the amount of output by
time restraints. Thus derivative takes action to inhibit more rapid changes of the measurement
than proportional action. Derivative is often used to avoid overshoot. The range is 0.00 through
10.00.
