10 Controller behaviour after switching power on
When starting-up the unit, the output signals may
interfere with the current process, depending on the last
mode of operation or structure.
The position of the configuring S90 determines the controller set-up
once the power supply is re-established.
The restart conditions should be selected in accordance with plant
requirements.
Under fail-safe conditions, the controller should be switched to ”No
automatic” immediately after switching on and the variable y should
be set manually. Then the c ontroller can be switched to ”Automatic”.
