DANGER
Hazardous voltage.
Will cause death or serious injury.
Disconnect power before working on
equipment
The switchgear must be installed in switchgear cubicles complying with
degree of protection IP32, IP43 or IP54, depending on the prevailing environ-
mental 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. Siemens AG, its subsidiaries
and affiliates (collectively "Siemens") are not in a position to evaluate all of the
characteristics of a given system or product or machine not designed by
Siemens.
Siemens accepts no liability for any recommendation that may be implied or
stated herein. The warranty contained in the contract of sale by Siemens is the
sole warranty of Siemens. Any statements contained herein do not create new
warranties or modify existing ones.
Application
The 3SE6806-2CD00 safety switching device can be used in safety circuits
according to VDE 0113 Part 1 (11.98) and EN 60 204-1 (11.98), for example with
moving screens and protective doors.
The device is suitable for evaluating the 3SE6 magnet monitoring device. How-
ever, it can only be used with devices equipped with 1 NO and 1 NC.
The safety switching device complies with DIN EN 954-1 up to Category 3,
depending on the external wiring.
Functions and connections
The 3SE6806-2CD00 safety switching device operates as an NO circuit withtwo
floating release circuits (safety circuits) and as a NC circuit using a floating sig-
naling circuit. The number of release circuits can be supplimented by connecting
one or more 3TK2830 expansion modules.
Three green LEDs indicate the status:
• LED POWER ON: Rated control supply voltage U
• LED CHA 1 ON: all NO contacts of the connected sensors are open.
• LED CHA 2 ON: all NC contacts of the connected sensors are closed.
Up to 6 protective devices can be be connected to the safety switching device.
The sensor inputs (terminals S**) are wired as shown in figures IIIto VII.
Cross-circuits between the sensor circuits, faults to earth and wire breaks are
detected by the safety switching device.
The "manual start" mode can be activated by wiring the terminals X1 and X2 as
shown in fig. IV and "automatic start" can be activated using terminals X1 and
X3 (Fig. V).
The device has six current-sourcing semiconductor outputs (Y1 to Y6) ) which
report the status of the connected safety devices.

Note
• A "manual start" using the ON switch is achieved via the downward pulse edge.
• If the feedback circuit is not required for an "automatic start", X1 can be bridged
with X3.
• When using the device in "automatic start" mode, an automatic restart by the
higher-level control after an emergency shutdown should be prevented according
to EN 60 204-1 sections 9.2.5.4.2 and 10.8.3.
