Robot zone access is monitored by light curtain LC1. The machine zone is further
protected by a safety door and an emergency stop circuit.
Sensor S3 is OR-linked with LC1 and detects the safe position of the robot.
This enables e.g. equipping through an opening in the processing area without
switching off the robot power supply. If the robot is not in the safe position when the light
curtain is interrupted, the entire machine and the robot are switched off.
Opening the safety door or actuating the emergency stop button also result in a safe
switch off. The robot control receives the command to switch off (returning to the safe
position) from Q1.
K1 and K2 immediately interrupt the power supply to other consumers. The power
supply of the robot is switched off safely via K4 and K5 after 1 s.
Restart is possible after exiting the danger zone and pushing Reset button S4.
