SETTING EXAMPLE 3: SWITCHING SETPOINT VALUE BY EVENT INPUT
The Controller has two discrete inputs for event control input.
At the maximum of four sets of temperature setpoints and PID parameters can be predefined and stored in the ‘banks.’ The
external event input can be used to switch among these banks.
In this example, the Controller is set according to the example 1 for the setpoint 40.0°C. By using banks, an additional setting
to switch the setpoint to 50.0°C by an event input is created.
(1) Connect a switch to the discrete input 1 as shown below.

(3) Click Auto-tuning button located below the trend graph to show the Auto-tuning dialog box. Choose Bank 1 and click OK.
The Controller go through auto-tuning and then starts control operations.
Now the setting is complete to switch the temperature setpoint to 50.0°C with the switch closed (ON) and to 40.0°C with the
same opened (OFF).
