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 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 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 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 relay C571-AC in EMERGENCY STOP 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. Using this device, max. Performance Level PL c
/ Cat. 1 according to DIN EN ISO 13849-1 and / or SIL 1 according to DIN EN /
IEC 62061 can be achieved. Depending on the estimated risk, it may be neces-
sary to carry out additional measures in the sensor circuit
(e.g. shielded cable laying).
When the safety relay is used in "Automatic Start" mode, automatic restarting
(as per DIN EN / IEC 60204-1, 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. The user
must carry out an evaluation of the overall systems.
Functions and connections
The safety relay 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 func-
tion.
When the EMERGENCY STOP button or the limit switch is unlocked and when
the ON button is pressed, the internal circuits of the safety relay and the exter-
nal 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.
