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 certi-

fied components.

The relay must be installed in switchgear cubicles complying with degree

of pro-tection 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 C576 in safety circuits as per

DIN EN / IEC 60204-1, e.g. with movable covers and guard doors; the safety relay

C577C577 in EMERGENCY STOP devices as per DIN EN / IEC 60947-5-5. Depen-

ding on the external circuit, 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 achie-

ved. The user must carry out an evaluation of the overall systems.

Functions and connections

The safety relay C576/C577 have two release circuits (safety circuits) configured

as NO circuits. The number of release circuits can be increased by adding one or

more C579 extension modules. Three LEDs indicate operating state and function.

When the EMERGENCY STOP button or the limit switch is unlocked and when

the ON button is pressed, the internal circuit of the safety relay and the external

contactors are checked for proper functioning.

On the C577, 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 STOP

button is closed.

Connect the EMERGENCY STOP button or the limit switch to terminals Y11, Y12,

Y21, Y22. Connect the ON button in series with the NC contacts of the external

contactors (feedback circuit) to terminals Y33, Y34.

The safety relay is protected by an internal self-healing PTC

fuse (multifuse).

Be sure to fit the specified fuses. Otherwise safe interruption

in the event of a fault cannot be guaranteed.
