WAL - Work Area Limitation Module Product overview
3 Product overview
3.1 Summary
The functionality of the WAL R1 module is described by using the imple-
mentation in the KeTop Safe Wireless System (KeTop T15x WL + CB4xx)
as an example. Both components contain the same WAL module and show
how it can be utilized:
To ensure that no dangerous actions of the machine or of machine parts
can be triggered outside of the visible area of the hazardous area, there is
an option for restricting the effective range when using a WAL R1 module.
The effective range restriction also offers the advantage of reducing the
probability of connection interruptions.
Various tactile and optical measures (e.g. vibration in the handheld device,
pulsation of the illuminated emergency stop) let the user know when the
limit of the effective range has been reached. Depending on the direction,
the frequency of these measures increases or slows down. If the user exits
the effective range, the frequency increases. If the user moves into the ef-
fective range, the frequency is reduced.
The maximum permissible effective range is 20 m and can be configured
on the base station (CB4xx containing WAL R1 module) using DIP switch-
es.
