Safety Relay - ABB C573 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 compo-
nents.
The devices must be installed in switchgear cabinets with an adequate
degree of protection which takes the ambient conditions into account.
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 char-
acteristics 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 relays C571 / C573 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 e / Cat. 4 according to
DIN EN ISO 13849-1 and/or SIL 3 according to DIN EN / IEC 62061 can be
achieved. Depending on the estimated risk, it may be necessary to carry out
additional measures in the sensor circuit (e.g. shielded cable laying). When
C571 / C573 is used as a contact extension, the PL / Cat. / SIL that can be
achieved is the same as for the basic device. The user must carry out an evalu-
ation of the overall systems.
Functions and connections
Safety relay C573 has three release circuits (safety circuits) which are config-
ured as NO circuits and a signal circuit configured as an NC circuit.
Safety relay C571 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 relay and the exter-
nal contactors are checked for proper functioning.
Connect the EMERGENCY STOP pushbutton or the limit switch in the supply
cable from A1 to +24 or L24 V. To evaluate over two channels, connect
Channel 2 from A2 to 0 V or N. Connect the ON button in series with the NC
contacts of the external contactor (feedback circuit) to terminals Y1 and Y2
(for circuit examples, see Figs. V to VIII).
