Safety Relay; Important Notice - ABB C572 Betriebsanleitung

Safety Relay

Operating Instructions
Read and understand these instructions before installing,
operating, or maintaining the equipment.
DANGER
!
Hazardous voltage.
Will cause death or serious injury.
Turn off and lock out all power supplying this device before
working on this device.
CAUTION
Reliable functioning of the equipment is only ensured with
certified components.
The safety 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 effec-
tiveness of the safety system by trained individuals. ABB AG, its subsidiaries
and affiliates (collectively "ABB") are not in a position to evaluate all of the cha-
racteristics of a given system or product or machine not designed by ABB.
ABB accepts no liability for any recommendation that may be implied or stated
herein. The warranty contained in the contract of sale by ABB is the sole war-
ranty of ABB. Any statements contained herein do not create new warranties or
modify existing ones.
Application
You can use the safety relay C572 in emergency tripping devices as per
DIN EN / IEC 60947-5-5, and in safety circuits as per DIN EN / IEC 60204-1, e.g.
with movable covers and guard doors.
Depending on the external circuit, max. Performance Level PL e / Cat. 4 accor-
ding to DIN EN ISO 13849-1 and/or SIL 3 according to DIN EN / IEC 62061 can
be achieved. The user must carry out an evaluation of the overall systems.
Functions and connections
Safety relay C572 has three release circuits which are configured as NO circuits
and two signaling cirucuits configured as an NC circuit. Three LEDs indicate ope-
rating state and function.
When the EMERGENCY OFF pushbutton or position switch is enabled and the ON
pushbutton is operated, the internal redundant safety relays, electronic circuitry
and external contactors are tested for proper functioning.
On the C572, 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 tripping
button is closed.
