CONTROL POINTS MODULE (7-CP)
There are four Control Points, each having a setpoint value and an
associated PID gain set value. A control point can be implemented at any time
to accommodate changing process requirements due to batch changeover,
level changes, etc.
The PID gain set values (ProP, Int, & Dert) may be optionally implemented
with the setpoint value. A Control Point can be loaded from the hidden mode
or by the user input (control points 1 and 2 only, see user input control point
(CP) function).
The control point overwrites the previous setpoint and optionally the PID
values. The unit begins controlling based on these new values. When a control
point is loaded, the controller suppresses the output ‘bump’ usually associated
with PID gain changes. Control points must be manually loaded and may be
used in conjunction with a running profile.
Control Point Set-up (CSEt)
Select the control point to be configured.
NO
CP-1
CP-2
CP-3
CP-4
Selecting NO returns the unit to the configuration access point.
Setpoint Value (SP-n)
Enter the temperature setpoint value for the selected control point. This
value is constrained to the setpoint low (SPLO) and setpoint high (SPHI)
range limits (see inputs configuration module).
SP-n - -999 to 9999
PID Values(PId)
Choose the option of loading the PID gain set values with setpoint value
when implementing a Control Point.
NO - Disables PID entries and returns to control point set-up (CSEt).
YES - PID gain set is implemented when control point is loaded.
Enter the desired PID gain set values.
Pb-n - Proportional Band 0.0 to 999.9%
It-n - Integral Time 0 to 9999 secs
dt-n - Derivative Time 0 to 9999 secs
PROFILES MODULE (8-PR)
Prior to programming a profile, it is recommended to configure the basic
controller operation. A profile is a series of one or more programmable ramp
and hold phases. A minimum of three parameters are required for a profile:
Ramp Rate (Pnrn)
Target Setpoint (PnLn)
Hold Time (PnHn)
Each profile can be programmed with up to eight ramp and hold phases.
Associated with each profile is a timed event output set that updates as the
profile advances. Additional parameters are provided which enhance the
controller and profile capabilities.
Profile Set-Up
Select which profile or timed event output to program.
PSEt - Pr-1 Profile 1
Pr-2 Profile 2
Pr-3 Profile 3
Pr-4 Profile 4
PE-1 Timed event output for profile 1
PE-2 Timed event output for profile 2
PE-3 Timed event output for profile 3
PE-4 Timed event output for profile 4
The programming parameters for each profile are the same. The operator
programs each phase and continues until all eight phases are programmed or a
ramp rate of -0.1 is entered. Shown below are the parameters for profile 1.
