SICK i110

3 Product description
3.1 Setup and function
The safety locking device is an interlocking device consisting of a mechanically-actu‐
a
ted position switch and a coded actuator. The actuator has a lower coding level. The
position switch contains a rotating switching cylinder which the actuator grips during
closing. The switching cylinder is locked or unlocked electromagnetically (variant-depen‐
dent).
When inserting and removing the actuator, switching contacts for door monitoring are
opened and closed. When locking and unlocking the locking device, switching contacts
for locking device monitoring are opened and closed.
If the locking device is locked, the actuator cannot be removed from the actuating head.
The locking device can only be locked when the protective device is closed.

Standby current locking principle
i110-M
•
L
ocking locking device: close protective device, no voltage on the magnet
•
Unlocking locking device: apply voltage to magnet
If voltage is interrupted at the magnet, the locking device remains locked and the pro‐
tective device cannot be opened immediately.
WARNING
T
he locking device locks even when voltage is not present
People could get trapped.
b
If people are in the hazardous area, do not close the protective device even volt‐
age is not present.
