Product operating principle
The
RADIOSAFE (RS)
«
Wireless safety logic signal transmission system»
is used to transmit logic safety signals from one
point of an installation to another.
The transmitter
RSEF
is designed to radio-transmit the following signals to the receiver
RSRD
:
-
An emergency stop signal in the event of a problem occurring in the installation
-
Up to 10 command signals
The receiver
RSRD
is integrated in the control component of the machine ; it enables (or not) operation of the machine and
transmits the possible commands assigned to the buttons connected to the transmitter
RSEF
.
The receiver
RSRD
stops operation of the machine when any of the following conditions are present :
Case 1 :
Deactivation of a safety input (for example : contact on a gate or an emergency stop) connected to the
transmitter
RSEF
Safety interlock subsequent to stop request.
Case 2 :
Action on emergency stop device wired to receiver
RSRD
.
Safety interlock subsequent to stop request.
Case 3 :
Interruption of radio link during use
When the system is in use, the transmitter
RSEF
has a continuous radio link with the receiver
RSRD
. Should this
link be interrupted for more than the passive stop time, the receiver automatically triggers stopping of the
installation.
Safety interlock prior to loss of control of stopping function.
Case 4 :
Detection of a malfunction (see section : « Faults communicated by receiver »)
