WARNING:
HAZARDOUS VOLTAGE
CAN CAUSE ELECTRICAL SHOCK
AND BURNS.
DISCONNECT POWER BEFORE PROCEEDING
WITH ANY WORK ON THIS EQUIPMENT.
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 charac-
teristics of a given machine 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 combination 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 (12.97), e.g. with movable covers and guard doors. Depending on
the external connections, safety categories 3 and 4 as per DIN EN 954-1 are
achievable.
When the safety combination is used in "Automatischer 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 combination C571-AC has two release (safe) circuits which are confi-
gured 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 combination and the
external contactors are checked for proper functioning.
Connect the EMERGENCY STOP button or the limit switch to terminals Y11, 12
and Y21, 22. The ON button is connected in series with the NC contacts of the
external contactor (feedback circuit) at terminals Y33, 34.
