5.7.3 Specifying the Setpoint Range When a Linear Input Is Used
The setpoint range, that is, the range of setpoint values the operator can enter using the
16C, 18C, and 25C front panel. This range will also apply to recipe setpoints, that is, to
soak levels specified using the ramp/soak parameters.
The Setpoint Low Limit and the Setpoint High Limit must not be set to the same value.
Parameter Name
: Setpoint Low Limit (89)
Name as Displayed
:
SP.LLSP.LL
Used By:
all controllers
When Displayed:
always
Range:
limited by the scaling defined for the input using the SCL.LSCL.L and
SCL.HSCL.H parameters in the InPInP (input) menu
Default:
depends on input type
Description:
This is the lowest value that can be entered as a setpoint (before
bias is applied).
Parameter Name:
Setpoint High Limit (90)
Name as Displayed
:
SP.HLSP.HL
Used By:
all controllers
When Displayed:
always
Range
limited by the scaling defined for the input using the SCL.LSCL.L and
SCL.HSCL.H parameters in the InPInP (input) menu
Default:
depends on input type
Description:
This is the highest value that can be entered as a setpoint
(before bias is applied).
5.7.4 Applying an Input Filter When a Linear Input is Used
You can configure the controller to average the input over a period of 0.1 to 10 seconds
before it uses the input value in the control algorithm calculations.
Parameter Name:
Input Filter (91)
Name as Displayed
:
I.FILI.FIL
Used By:
all controllers
When Displayed:
always
Range:
0.1 to 10.0 seconds
Default:
0.5
Description:
Used to specify the time period over which the controller will
average the input before using the input in the control algorithm.
