PID Operation Operating Instructions
3. Operation
This chapter describes how to run the controller in various situations, from
simple operations to more complex ones.
∑
Setting up the basic parameters
∑
Test operation (in local/manual mode)
∑
Automatic operation (in local/automatic mode)
∑
More convenient automatic operation (using area switching)
Warning:
Do not turn on power or the air supply to the actuator (for
control valves, etc) until you are instructed to do so.
When the controlled unit is a control valve, keep the inlet
shutoff valve closed until you are instructed to open it.
If you encounter any problems or the controller does not work as expected
while completing these steps, go to "7. Troubleshooting" on page 84 to
analyze the problems.
3.1 Setting Up the Basic Parameters
Before using the controller, you must set up the following two
parameters (basic parameters):
1. Measurement input (PG02)
2. Control output (PG03)

How to Set Up Basic Parameters
This step-by-step procedure describes how to set up the basic
parameters .
1
Turn on the controller.
Do not apply power
or the air supply to the actuator (for
control valves, etc.)
at this point.
2
Set the controller in LOC mode by referring to " Key
Operation Flow" on page 25. If the REM indicator lamp is off, it
is already in LOC mode, so you can omit this step.
