3.2
Application
The device is designed for use on machines and plants whose motions or moving parts can
constitute a hazard to personnel or machinery.
The device continuously carries out standstill monitoring (output circuit 13/14) and speed
monitoring (output circuit 23/24). For speed monitoring, there is a choice between automatic
and setup mode.
With the corresponding circuitry and suitable additional components (such as drives, sensors
and tripping elements), the 3TK2810-1 can be used to implement the safety functions STO (safe
torque off), SOS (safe operating stop), SLS (safely limited speed), and SSM (safe speed monitor)
from the EN 61800-5-2 standard.
Note
Routing of the sensor cables
If electromagnetic interferences are to be expected, all initiator/encoder cables must be shielded
when laid. The shielding must be connected to PE at both ends.
