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!
