Automation task:
In a logistics center, several roller shutters are available for persons and industrial trucks such as e.g. forklift trucks and other motor-driven means of transportation.
In order to pass more easily and more rapidly, opening and closing of these roller shutters is to be automated taking into consideration the protection of persons and goods. Outside the working hours, it must not be possible to open the roller shutter except by especially authorized personnel. Automatic control of the roller shutter is to be realized centrally by means of a module.
Automation solution:
To control the roller shutter motor, the automation solution uses a LOGO! logic module with display and integrated date and time function. Three optical sensors SIMATIC PXO200 connected to the LOGO! logic module ensure the detection of incoming and outgoing objects as well as of objects in the hazardous area.
The LOGO! logic module controls the roller shutter motor by means of a reversing contactor combination consisting of two SIRIUS contactors. The motor is protected by means of a SIRIUS circuit breaker.
The calendar function of the LOGO! logic module allows locking of the roller shutter outside the working hours. Authorized personnel can activate or deactivate this calendar function by means of a key-operated switch.
