2-7 : Operation of external adjustment switch (with indicator)
Data can be read by the SFC even while the external adjustment switch is in
operation. What is read is data immediately before the adjustment mode was entered.
~Note:
•
If an SFC communication has been started while operating the external
adjustment switch, adjustment will be stopped as long as the communication
continues.
• In the case of the DE output mode, the external adjustment switch cannot be used.
•
The change is reflected in the output after the normal condition is recovered from
the adjustment mode.
• Do not use a magnetic driver because this may prevent accurate adjustment.
•
In the case of an engineering unit (real scale) display format, it may take a few
seconds after each adjustment mode is entered until a correct value is displayed.
• Start operation after correct value appears.
