Description
Solenoid operating voltage and LED function display
- 24 V AC/DC -15%, +10%
Guard locking type
TZ2 | Open-circuit current principle, guard locking by applying voltage to the solenoid. Release by spring force. |
Switching elements
SK | For monitoring the door/actuator position |
ÜK | For monitoring the guard locking (built-in solenoid) |
2131H | Slow-action switching contact 3 NC |
3131H | Slow-action switching contact 2 NC |
Emergency release
It is used for manual release of the guard locking without tools in an emergency. The emergency unlocking mechanism must be returned to the locked state manually. Sealing can be fitted to protect against tampering. Lead seal kit and tool included (already pre-assembled on versions with plug connectors).
