5.6.2 Specifying the Setpoint Range When a Temperature Input is Used
Configure 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:
sensor low limit to sensor high limit
Default:
–328 (See Note 1 below.)
Description:
This is the lowest value that can be entered by the operator as a
setpoint (before bias is applied). This limit is also applies to
ramp/soak recipe soak levels.
Parameter Name
: Setpoint High Limit (90)
Name as Displayed
:
SP.HLSP.HL
Used By:
all controllers
When Displayed:
always
Range
sensor low limit to sensor high limit
Default:
1400 (See Note 1 below.)
Description:
This is the highest value that can be entered by the operator as
a setpoint (before bias is applied). This limit is also applies to
ramp/soak recipe soak levels.
Note 1: The default value depends on the input type. The default value shown applies
when the input type is a J thermocouple.
5.6.3 Applying an Input Filter When a Temperature 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.
