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 components.
The safety switching device must be installed in switchgear cubicles com-
plying with degree of protection IP32, IP43 or IP54, depending on the pre-
vailing 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 C6700 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. for moving covers and protective doors. Max. Performance Level PL d / Cat. 3
according to DIN EN ISO 13849-1 or SIL 2 according to DIN EN / IEC 62061 can be
achieved, depending on the external circuit elements. The user must carry out an
evaluation of the overall systems.
Functional description and instructions for connection
The C6700 safety relay has two solid-state outputs. Three LEDs indicate the
operating state and the function.
During operation, all internal circuit elements are cyclically monitored for faults.
Connect the EMERGENCY STOP button and the position switch to terminals
Y11, Y12 or Y21, Y22. Connect the ON button in series with the NC contacts of
the external actuators (feedback circuit) to terminals Y33, Y34 .
The C6700 safety relay and the activated contactors K1 and K2 must have the
same frame potential.
Performance Level PL d according to DIN EN ISO 13849-1 and / or SIL 2 accor-
ding to DIN EN / IEC 62061 can only be achieved in combination with 2 external
actuators with positively-driven feedback contacts.
Use a power pack to IEC 60536 safety class III (SELV or PELV)
for power supply!
