8. USE
8.1 Commands and signals
This control unit is designed to stay switched on permanently. The control unit can only be started again in either of the
following cases:
• Automatic restarting following detection of a fault in execution of the software, and subsequent intervention of the
watchdog circuitry.
• Manual restarting after switching off altogether (e.g. for maintenance of repair works on the plant).
In both cases, restarting is interpreted as a fault and is indicated by the yellow LED staying on. This means that correct
functioning of the control unit and subsequent calibration are required after each restart.
WARNING WARNING
After having carried out the calibration, close the control unit door by means of the dedicated key supplied.
The control unit configuration must be carried out / changed only by qualified technicians with adequate training.
