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 wor-
king on this device.
CAUTION
Reliable functioning of the equipment is only ensured with certified
components.
The devices must be installed in a switchgear cabinet with the IP32, IP43 or IP54
degree of protection, depending on the ambient 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 effectiveness of
the safety system by trained individuals. Siemens AG, its subsidiaries and affili-
ates (collectively "Siemens") are not in a position to evaluate all of the characteris-
tics 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 war-
ranty of Siemens. Any statements contained herein do not create new warranties
or modify existing ones.
Applications
3TK2834 is suitable for installation in controls for presses.
- Hydraulic presses DIN EN 693
- Eccentric and related presses DIN EN 692
- Screw presses DIN EN 692.
Using this device, max. Performance Level e / Cat. 4 according to
DIN EN ISO 13849-1 and / or SIL 3 according to DIN EN IEC 62061 and / or cate-
gory III C according to DIN EN 574 can be achieved. The user must carry out an
evaluation of the overall systems.
Functions and Connections
The two-hand control unit 3TK2834 possesses two release circuits in the form of
NO circuits and two signal circuits in the form of NC circuits. Five LEDs indicate
the operating status and the functions.
The release circuits are closed by simultaneous operation (< 0.5 s) of the pushbut-
tons S1, S2. If one pushbutton is no longer pressed, the release circuits open.
They do not close again until both pushbuttons are no longer pressed and then
simultaneously pressed again.
1. Apply the operating voltage (UB) to the terminals A1 and A2. The operating
voltage must be de-energized with the operating energy of the press.
2. Close the feedback circuit:
Connect the bridge to Y11, Y12 or NC contacts of external contactors.
3. Connect the input circuit:
Connect pushbutton S1 to terminals Y21, Y22, Y23 and
pushbutton S2 to terminals Y31, Y32, Y33.

The unit cannot be started with the following faults:
- Short-circuit, e.g. between the pushbuttons
- Defective relay coils
- Conductor failure
- Welded contacts
The output relays do not pick up if
- the pushbuttons are not pressed simultaneously (< 0.5 s)
- only one pushbutton is pressed
- the feedback circuit Y11, Y12 is open.
