IR Link
7.3.1 Feature and Benefits
Cattron Excalibur, LRC-M, LRC-L and SCU32 controllers are able to use IR (Infra-Red) Link functionality.
IR Link functionality makes it possible to define one or more precise zones, in which the function of an Operator
Control Unit (OCU) can be enabled. It could, for example, enable an OCU to start working, or it can change the
way a controller is allowed to work based on its location and presence relative to a specific IR transmitter.
This functionality can be used to prevent unintentional system start until an operator is in a precise location, such
as under a crane or by a machine, and by doing so prevent accidents that can be caused due to the following
scenarios.
•
An employee or visitor picks up a controller and moves the controls around, unaware that it is actually
operating a crane with consequentially dangerous results.
•
An employee is working on a controller in a workshop and has not isolated the crane supply; the crane
moves around, causing material damage and narrowly misses causing serious injuries or death to
personnel.
•
An operator picks up the wrong controller, fails to verify the identity of the crane, and, while thinking it is
not working, a crane behind him is moving, which hits an adjacent crane with a suspended press die that
then swings into the press and is irreversibly damaged.
When a system is configured to control functionality by the presence of a specific IR transmitter, it makes it
possible to automate the selection of some function or piece of equipment, eliminating manual selection errors
and keeping the operator in a safe location.
All these features improve efficiency, enhance safety, and prevent damage to materials and personnel, and so
improve productivity.
7.3.2 Features Options
The features that are made possible with the Infra-Red Link are:
•
Infra-Red Close Start
– requires an OCU to visit a zone before operation becomes possible
•
Infra-Red Function Enable
– requires an OCU to stay in a zone to continue operating
•
Infra-Red Zone Control
– passes positional information to the OCU that is then sent to the MCU
These features require one or more Infra-Red (IR) transmitters on the machine and an IR sensor that is built into
the OCU.
The LRC-M, LRC-L and SCU32 are able to use all features; the Excalibur is able to use Close Start and Function
Enable.
