Before the robot cell can be entered, a stop of the process must be requested. This task can be solved with the BDF200 control panel control panel. The running process is completed after the stop request and then the door is unlocked. The AZM201 solenoid interlock prevents unintentional start of the machine after opening the door. All safety functions of the cell are handled by the PROTECT PSC1 modular safety controller.
Pallets are conveyed to the palletising station via the infeed and outfeed. Here it is necessary to protect the worker from dangerous movements. To distinguish the worker from a pallet, differentiation between people and material is necessary. This is easily and reliably solved with the SLC445 safety light curtain and the MCU-02 muting module.
If goods or objects need to be transported in or out of the hazardous area without stopping the machine, the safety light curtain must be automatically and temporarily suspended. Two or four muting signals are used to detect whether a person is approaching the hazardous area or a transport system is entering or leaving the hazardous area.
In extensive plants, a high wiring effort quickly arises in the task of routing all signals of the safety components to the safety controller. The SFB safety field box offers an efficient solution. Safety-related signals are collected decentrally and sent to the central safety controller via a safe fieldbus.
The safety functions of the machine are performed by the PSC1 modular safety controller safety controller. Control devices such as the BDF200 control panel or solenoid interlocks such as the AZM201 are evaluated or controlled in a safety-related manner. Thanks to the modular concept of the PROTECT PSC1, the safety controller can be individually adapted to the requirements of the application.
