Overview
SIRIUS 3TK2810 safety relays
3TK2810-0 standstill monitors
The standstill monitor increases safety in hazardous areas.
Without a sensor, it detects motor stoppage from the residual
magnetization of the rotating motor. When an adjustable
threshold value is undershot, it uses its outputs to allow access
to hazardous areas, for example by unlocking a protective door.
3TK2810-1 speed monitors
The speed monitor combines two safety functions in one unit by
continuously monitoring machines and plants for standstill and
speed.
Through simple parameterization and permanent diagnosis on
the display, faults can be quickly remedied at any time – often
before they cause plant downtimes.
In addition to standstill and speed monitoring, the unit also
features an integrated monitoring function of a protective door
with spring-type interlocking. Therefore, an additional evaluation
unit is not needed.

Signaling of faults with diagnostics display
•
Standstill time can be set
•
Unit can be used with frequency converters
3TK2810-1 speed monitors
•
Menu-prompted, easy parameterization
•
Direct diagnosis on the display means shorter downtimes
thanks to early fault detection
•
Integrated protective door monitoring means greater safety
because access to the plant is allowed only in the safe state
