CAUTION
Before starting communication between the SFC in a system with analog output and
the transmitter, be sure to change the control loop to “manual control”. This is to pre-
vent fluctuation in analog output of the transmitter, which is caused by starting the
SFC and communicating with the transmitter, from directly affecting the control loop.
Use the following procedure to start the SFC. The key operations of the SFC and dis-
play of the display window slightly vary depending on whether the system has digital
output or analog output.
