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 safety relay 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 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

The C6702 safety relay can be used in EMERGENCY STOP devices according to

DIN EN / IEC 60947-5-5 and in safety circuits according to

DIN EN / IEC 60204-1, e.g. in movable guards and protective doors or in non-

contact protective devices in accordance with DIN EN / IEC 61496-1 , electrical

equipment for furnaces in accordance with DIN EN 50156-1 and automatic firing

systems for gas burners in accordance with DIN EN 298 . Depending on the

external circuit, max. Performance Level PL e / Cat. 4 according to

DIN EN ISO 13849-1 and/or SIL 3 according to IEC 62061 can be achieved. The

user must carry out an evaluation of the overall systems.

Functional description and instructions for connection

The C6702 solid-state safety relay has one safe solid-state output and one time-

delayed safe solid-state output. Three LEDs indicate the operating state and the

function.

When the device is put into operation it runs through a self-test to test the

correct functioning of the internal electronics. All internal circuit components

are monitored for faults cyclically during operation.

Connect the EMERGENCY STOP button and/or the position switches or light

arrays to terminals Y11, Y12 and Y21, Y22. Connect the ON button in series with

the NC contacts of the external actuators to the supply voltage L+ (24 V DC) and

to terminal Y34. Connect cascading input 1 either via a safe output or directly to

the supply voltage L+ (24 V DC).

External actuators or loads can be switched via safe outputs 14, 24. It must be

ensured that the actuators or loads and the C6702 electronic safety relay have

the same frame potential. Paralleling outputs 14 and 24 to increase the load cur-

rent is not permissible.

If electronic sensors (light-array monitoring, etc.) are used, and in single-channel

operation, Y35 must be connected to L+ (24 V DC). For autostart operation, Y32

must be connected directly to L+ (24 V DC) and Y34 must be connected to it via

NC contacts of the external actuators.

Use a power pack to IEC 60536 safety class III (SELV or PELV)

for power supply!
