Contact mats are used on...
-
machines, plants and robotic systems where
the areas of danger are unchecked accessed
-
plants where the presence of a person at a certain
position is necessary
-
elevators, in order to prevent the unallowed
entering of the elevator roof
-
building entrances

| Safety Contact Mats are used for safeguarding areas of danger
on machines and plants with the aim of preventing unchecked access. The
switching mat can be individually adapted to the area which has to be secured.
With the help of the closed-circuit-principle a constant monitoring of the
safety contact edge is insured. |

Functional
description |
|
| The STM safety contact-making mat is fitted
with two two-core connecting cables and offers the possibility of connecting
several mats in series up to a maximum total area of 10 m2. One end of the
cable is connected to the evaluation electronics and the terminal resistance
is connected to the other end (prepared accordingly at the factory). The
electronics now monitor the entire conductor route, including the mats,
through to the terminal resistance. The contact-making surfaces make contact
in the event of external forces acting on the mat and the resistance is
bridged. This immediately causes a signal within the electronics that is
then given as a potential-free output for contact-making by the relay. The
entire switching arrangement is monitored at the same time for cable rupture
or manipulation. |

simple
assembly |
|
If the underground is to some extent flat,
clean and free of from outside parts, the assembly is very simple and
economical. It has to be merely made sure that the connection managements
of the switching mat are transferred suitably for the mutual connection.
All switching mats get connected to each other and the lines are transferred
on the circulation edge of the switching mats. The circulation edge is
attached around the area, it is made sure by what that all connection
lines are led for certain. The underground is finally drilled and suitable
fastening means to save the circulation edge are attached. The wiring
of the switching mats to the end judging device is just as simple since
only two connection wires are available for the complete system. Only
a minimum of technical experiences is therefore required. An illustrated
Operating instructins is available. |

Safety
Switchgear SK 41/32 |
| |
 |
The single-channel SK 41-32
switchgear finds application in the evaluation of safety contact mats
as well as in providing security of pinch and shear points caused
by safety contact edges and safety bumpers. The switchgear is designed
in accordance with EN 954-1 for Category 3. In order to meet Category
3 requirements, the switchgear has been
designed to be redundant, diversified, and equipped with two safety
relays which query each other and are force guided. In order to permit
the quiescent current of the circuit element to be monitored, a terminal
resistor has been integrated in the signal transmitter. When
the desired quiescent current is flowing, the output relay is activated
and the switching contact is closed. If the signal transmitter is
activated or the safety circuit is interrupted, the relay switching
contact opens. The switch states of the relays and the applied circuit
voltage are indicated by LEDs. |
