Design and Function
Attention!
Hazards must be ruled out before a key can be removed
!
at any time and the movable part of the guard can then be
opened!
The switch unit must be integrated into a system and connected with a
control unit so that the hazardous machine can only run when the guard
is locked and closed.
The machine can only be restarted after the key was returned to its
original position. Key removal is queried by the contacts of key monitoring.
SX01M is usually used in the system in connection with additional STS
units and SAFEMASTER products (e.g. Emergency stop module LG 5925,
Softstarter with DC-Brake BL 9228). The key to be removed can serve as
protection against lock-in or for the operating release of additional units
(e.g. M10A, M11A, M12M, M10B01M).
