Control of the interlocking solenoid
The interlocking solenoid is controlled by the control system via ASInterface bus bit D0. Simple connection to the bus is sufficient for process protection. For personal protection, further measures must be taken to ensure safe power switching.
Safety switches can be unlocked by means of the mechanical release in the event of power failure, for example. The mechanical release must be sealed to prevent tampering (for example with sealing lacquer).
