• If there is a temporary power failure or after switch-off, the manual functioning as well as the
previous output percentage value will be maintained at restarting.
• If the sensor breaks during automatic functioning, the controller switches to manual mode while
maintaining the output percentage command unchanged as generated by the PID immediately
before breakage.
Ex: on an extruder the command in percentage of the resistance (load) is maintained also in case of
input sensor failure.
