Important Notice - ABB C571-AC Betriebsanleitung

Safety Switching Device
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.
Reliable functioning of the equipment is only ensured with certified components.
The safety switching device 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. ABB AG, its subsidiaries and
affiliates (collectively "ABB") are not in a position to evaluate all of the characte-
ristics of a given machine or product.
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 switching device C571-AC in EMERGENCY STOP devices
as per EN 418 and in safety circuits as per VDE 0113 Part 1 (11.98) and/or
EN 60 204-1 (11.98), e.g. with movable covers and guard doors.
Safety category 2 according to DIN EN 954-1 can be achieved by using this
device.
When the safety switching device is used in "Automatic Start" mode, automatic
restarting (as per EN 60 204-1, Sections 9.2.5.4.2 and 10.8.3) must be prevented
by the higher-level control system in the event of EMERGENCY STOP.
Functions and connections
The safety switching device C571-AC has two release (safe) circuits which are
configured as NO circuits. The number of release circuits can be increased by
adding one or more C579 extension modules. Three LEDs indicate the operating
state and function.
When the EMERGENCY STOP button or the limit switch is unlocked and when
the ON button is pressed, the internal circuits of the safety switching device and
the external contactors are checked for proper functioning.
Connect the EMERGENCY STOP button or the limit switch to terminals Y11, Y12
and Y21, Y22. The ON button is connected in series with the NC contacts of the
external contactor (feedback circuit) at terminals Y33, Y34.

*) This wiring example only satisfies category 2 according to EN 954-1 if a warning is
automatically generated when the actuator fails or the machine control initiates a safe
state. Otherwise an alternative shut-down method is required.
