Figure 7.1: Two type 4 AOPDs each with two safety-relevant transistor outputs, manual restart (RES)
and contactor monitoring (EDM, K3 and K4)
The following circuit shows the connection of an AOPD in a location-of-hazard safeguard. An E-Stop
button is provided in this circuit.
Figure 7.2: One type 4 AOPD with two safety-relevant transistor outputs, two-channel E-Stop button,
RES and contactor monitoring (EDM, K3 and K4)
The following circuit shows the connection of an AOPD (laser scanner) in a danger zone guarding system.
With this circuit, a reset button can deactivate the start/restart interlock.
