1.1 Easy Tune
If the Controller has been configured for Easy Tune operation, all tuning is executed
automatically; no operator action is required.
1.2 Manual Tuning with Pre-Tune
When the Controller is configured for Manual Tuning, the Pre-Tune facility is available.
Pre-Tune is used to optimise system start-up (normally after power-up or after a major
change to the process being controlled). To activate Pre-Tune:
1. Select the
Process Variable
display.
2. Press Up key.
NOTE: Pre-Tune cannot be activated if the ProcessVariableiswithin5%of
input span from the setpoint.
To dis-engage Pre-Tune:
1. Select the
Process Variable
display.
2. Press the Down key.
This decimal point
indicator will flash
whilst Pre-Tune is
active.
NOTE: Pre-Tune is a single-shot operation and, therefore, when it is
completed, Pre-Tune will dis-engage itself automatically.
