Explosion Protected Machine Safety
|
Totally new in concept, the
Pico-Gard Machine Safety System utilises light beams travelling through optic
fibres to form circuits instead of the usual electrical circuits. This results
in a very simple-to-install system with many advantages over the conventional
approach. |
In addition, using only a light
beam, these circuits may be used in hazardous areas with the controller being
kept in a Zone 2 or safe area, thus providing Safety Category 4, per ISO 13849
(EN 954-1) and IEC 61496-1 Type 4 requirements, using a single switch point for
each door. This is possible due to its patent pending, diverse-redundant,
self-checking controller specifically designed to be used with plastic
fibre-optic cable. |

This eliminates cumbersome
armoured cables, conduits, bulky flameproof safety switches and explosionproof
glands, the entire appearance of which, may also be in contrast to the
appearance of the equipment installation.
Installation is incredibly simple; switches install instantly with
cut-to-length plastic fibre-optic cable and snap-lock connectors.
Multiple optical elements can be connected in series on a single
optical channel, providing the ability to monitor several dangerous
points with a single channel. Additional guarding points can easily
be added at any time by inserting optical elements into an existing
optical channel.
