CTM-LBI-BR-U-AZ-SA-161638 (Order no. 161638)

Description

Unicode evaluation

Each actuator is highly coded (unicode). The switch detects only taught-in actuators. Additional actuators can be taught-in. Only the last actuator taught-in is detected.

Guard locking type

CTM‑LBIGuard locking operated by means of input signal.

This type of guard locking has a function to prevent

  • persons from unintentionally locking themselves inside if the safety door is open in case of a power failure or if the machine is switched off.
  • the deactivation of the activated guard locking in case of a power failure.
