Design and Function

There are various option modules available for the integration
command functions into the safety switch and key transfer system
SAFEMASTER STS. In doing so, up to 3 command devices can be
incorporated per module. These may comprise illuminated buttons and
emergency stop buttons. The illuminated buttons can be provided with
different symbols and colours by the customer. A transparent coloured
trim and an unprinted symbol plate are included. Further coloured trims
and symbol plates are available as accessories.
The option module is installed underneath electrical modules such
as switch modules or locking switch modules. The connection can
be implemented via special connection sets or conventional wiring
between electrical modules and option modules. With the wiring sets,
the connection with plug-in connectors is established by means of a
ribbon cable with switch modules or 2 ribbon cables with locking switch
modules.
The option module also allows a simple and direct connection of 2 wires
per contact with a cross-section of up to 1.5 mm
terminal. The double cage clamp terminals can be plugged in and enable
option modules to be cascaded. The terminal numbering of the electrical
modules will be continued in the option module.
With the incorporation of an option module into the SAFEMASTER STS
switch / locking switch units, the attached functionalities can significantly
increase the operating speed of the SAFEMASTER STS system. With
switch / locking switch units that monitor one or more access points, this
can also reduce the down times of the machine.
