Adjustment/diagnostics:
● Device settings via menu-driven display or RJ45 (FCC Western Modular 8P8C) with
connecting cable (copy function)
● Selectable modes:
– Automatic mode: Monitoring of automatic speed window and standstill speed.
– Setup mode: Monitoring of setup speed window. Standstill permanently enabled.
● Autostart/monitored start
● LED displays for status diagnostics
● Display for status diagnostics and device parameterization
Installation conditions:
● The devices must be installed in control cabinets with degree of protection IP54 or higher,
taking account of the ambient conditions.
2.2 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 EMC interference is to be expected, all initiator/encoder cables are to be shielded when
laid. The shielding must be connected to PE at both ends.
