Ismertetés
Escape release
This is used for manual release of guard locking from the danger zone without tools.
Safety switch
The device may be operated only in conjunction with the actuator CET-A-...
Important: The actuator must be ordered separately.
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.
Solenoid operating voltage
- DC 24 V +10%, -15%
Guard locking type
CET1 | Closed-circuit current principle, guard locking by spring force. Release by applying voltage to the guard locking solenoid. |
LED function display
State LED | Status LED |
DIA LED | Diagnostics LED |
LED 1 rd | freely configurable |
LED 2 gn | freely configurable |
Additional connections
OUT | Monitoring output (semiconductor) |
RST | Reset input |
J | Teach-in input |
Category according to EN ISO 13849-1
Due to two redundantly designed semiconductor outputs (safety outputs) with internal monitoring suitable for:
- Category 4/PL e according to EN ISO 13849-1
- The stated safety characteristics apply to any installation orientations of the safety switch.
Important: To achieve the stated category in accordance with EN ISO 13849-1, both safety outputs (OA and OB) must be evaluated.
Wire front release (bowden)
The wire front release (bowden) permits remote unlocking of the guard locking via a pull wire. Flexible routing of the pull wire permits release of the guard locking in inaccessible installation situations.
Important: The wire front release (bowden) is not a safety function.
