To change the CN9000A's Default Parameters to new parameter
settings, refer to this section and Section 3.6. All adjustable
parameters are held in memory.
There are two classes of Functions. Functions .0 through .25 are
STANDARD FUNCTIONS that are used more often and are easily
accessible to the user. Functions .26 through .50 are known as
ADVANCED FUNCTIONS. They are not designed to be changed
in the normal operation and should not be accessed except during
setup by qualified personnel.
NOTES
Because the selection of tenth degree resolution (Function .18
Option 1), °C/°F selection (Function .22), and setpoint range
adjustments influence the values of other settings and can have a
fundamental effect on control characteristics, it is important that,
when required, they should be made during initial set-up to avoid
the need for re-tuning.
If the temperature units scale (°C or °F) is changed, it is essential
to change the upper bezel to correspond to the units selected
(supplied with controller).
If you are having difficulty in adjusting the Options, refer to Section
3.13, Parameter Lock, since the unit may be in the locked mode.
Normal control is maintained with existing settings during
programming.
You need to know the Option code and Function number to set up
the CN9000A. For example, Option 0/Function .5 is SP1
Proportional Band of 2.5%.
Appendix A lists all the Function numbers and their names in a
short concise list.
Table 3-4 describes the Option details for Standard Functions
.0- .25.
Table 3-6 describes the Option details for Advanced Functions
.26 - .50.
