Description
Unicode evaluation
Each actuator/key contains a transponder with high coding level according to EN ISO 14119. The evaluation unit detects only actuators that have been taught-in. Additional actuators can be taught-in. Only the last actuator taught-in is detected.
AS-Interface
ASi-3 protocol PUR connecting cable with flying lead, 2-core
AS-Interface inputs
D0, D1, D2, D3 Detection of actuators/keys. Evaluation takes place via a safety monitor
LED function display
The STATE LED indicates the status of the switch. The DIA LED indicates whether an error has been detected in the switch
