5. Setting value memory function [Option code: SM7]
If the option [SM7] is applied, a maximum of 7 files of data can be memorized, and when selecting a desired
file, the desired control can be performed.
In one (1) file are 14 kinds of data: Main setting value, PID each value, Cooling control proportional band
value, Alarm setting values (A1 to A4), Overlap band/Dead band value, Main output high limit, Main output
low limit, Cooling output high limit and Cooling output low limit can be memorized and selected.
To select the setting value memory number (File number), connect the terminals between each of 13 to 16
as shown below table.
Up to approximately 50 units of CF1H can be connected in parallel.

When the Setting value memory number is selected by external operation,
the number cannot be selected by front key operation.
When selecting the memory number by front key operation, all terminals
(b

and COM) should be open.
Memory number cannot be changed during setting mode or PID auto-tuning.
Setting value memory function operating procedure
(1) In the PV/SV display mode, select the setting value memory number by
connecting the terminals.
(2) In the setting mode, set each setting value; Main setting, PID each value,
Cooling control proportional band value, Alarm setting values (A1 and A2),
Overlap band/Dead band value, Main output high limit, Main output low
limit, Cooling output high limit, Cooling output low limit.
(3) After setting, press the MODE key to revert to the PV/SV display mode.
Registration
The setting data is registered to the file whose number is indicated
on the Setting value memory number display.
When the number is called up, the selected number by terminal connection
is displayed, and the control is performed by the data (setting value) of the file.
To change the setting values, repeat the operation above-mentioned, and
the values will be changed to new values.
