Safety combination
Instructions
WARNING:
HAZARDOUS VOLTAGE
CAN CAUSE ELECTRICAL SHOCK
AND BURNS.
DISCONNECT POWER BEFORE PROCEEDING
WITH ANY WORK ON THIS EQUIPMENT.
The switchgear must be installed in switchgear cubicles complying with
degree of protection IP 32, IP 43 or IP 54, 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 effecti-
veness 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 charac-
teristics of a given system or product or machine not designed by
ABB.
Siemens 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
warranty of ABB. Any statements contained herein do not create new warranties
or modify existing ones.
Application
The C6701 safety combination can be used in EMERGENCY STOP devices accor-
ding to EN 418 and in safety circuits according to EN 60 204-1 (11.98), e.g. in
movable guards and protective doors or in non-contact protective devices in
accordance with IEC 61496-1 (06.98), electrical equipment for furnaces in accor-
dance with DIN VDE 0116 (10.98) and automatic firing systems for gas burners in
accordance with DIN EN 298 (02.94). Depending on the external circuit ele-
ments, safety category 4 according to DIN EN 954-1 or SIL 3 according to
IEC 61508 can be achieved.
Functional description and instructions for connection
The C6701 safety combination has two reliable solid-state outputs. 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 C6701 electronic safety combination
have the same frame potential. Paralleling outputs 14 and 24 to increase the
load current is not permissible.
If electronic sensors (e.g. light-array monitoring) 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!
