Safety Relay

Operating Instructions
Read and understand these instructions before installing, operating, or maintai-
ning the equipment.
!
DANGER
Hazardous voltage.
Will cause death or serious injury.
Disconnect power before working on
equipment
The relay must be installed in switchgear cubicles complying with degree
of protection IP32, IP43 or IP54, depending on the prevailing environmental
conditions.
IMPORTANT NOTICE
The products described herein are designed to be components of a customized
machinery safety-oriented control system. A complete safety-oriented system
may include safety sensors, evaluators, actuators and signaling components. It
is the responsibility of each company to conduct its own evalution of the effecti-
veness of the safety system by trained individuals. Siemens AG, its subsidiaries
and affiliates (collectively "Siemens") are not in a position to evaluate all of the
characteristics of a given system or product or machine not designed by
SIEMENS.
Siemens accepts no liability for any recommendation that may be implied or
stated herein. The warranty contained in the contract of sale by Siemens is the
sole warranty of Siemens. Any statements contained herein do not create new
warranties or modify existing ones.
Application
You can use the safety relay 3TK2822 in safety circuits as per VDE 0113 Part 1
(11.98) or EN 60 204-1 (11.98), e.g. with movable covers and guard doors; the
safety relay 3TK2823 in EMERGENCY STOP devices as per EN 418. Depending on
external connections, category 4 as per DIN EN 954-1 is achievable.
Functions and connections
The safety relays 3TK2822/23 have two release circuits (safety circuits) configu-
red as NO circuits. The number of release circuits can be increased by adding
one or more 3TK2830 extension modules. Three LEDs indicate operating state
and function.
When the EMERGENCY STOP button or the limit switch is unlocked and when
the ON button is pressed, the internal circuit of the safety relay and the external
contactors are checked for proper functioning.
On the 3TK2823, the ON circuit Y33, Y34 is checked for short-circuit. This means
that a fault is detected when Y33, Y34 is closed before the EMERGENCY STOP
button is closed.
Connect the EMERGENCY STOP button or the limit switch to terminals Y11, Y12,
Y21, Y22. Connect the ON button in series with the NC contacts of the external
contactors (feedback circuit) to terminals Y33, Y34.
