2.1 GENERAL INFORMATION
General block diagram
The BRAVO type ELCA Radio Remote Control System is a family of industrial safety radio remote controls that can
be used for the control of lifting, transportation and general equipment on machines where specific safety features are
required on the Stop command (Cat. 3 PL d or cat. 4 PL e) and on the unintended activation of Joystick commands in
the rest position (UMFS Cat. 3 PL d). On request, it is possible to have UMFS with Cat. 3 PL d also on particular On/Off
controls. (in accordance with EN ISO 13849-1)
The BRAVO type radio remote control system is composed of two main parts:
1. The transmitting unit (AT BRAVO-FUNK-915) that allows the user to communicate to the receiver the sequence
of digital data that form the selected command.
2. The receiving unit (AR BRAVO-FUNK-915) that decodes the sequence of digital data and transforms them into
electric impulses that the machine requires to activate the selected command.
The system, which uses electromagnetic waves to transport the control signals, enables the operator to freely move
around the machine giving the possibility to position himself where it is possible to better control its movements and to
choose a safer operating position in total freedom.
The radio remote control is designed in order to be used when an interference-free frequency is activated so as not to
disturb other devices in the vicinity and vice versa not be disturbed. During transmission, the system checks transmission
status and, in the presence of a disturbance, is capable of automatically changing the transmission frequency without
interruptions. Any command transmitted contains a unique code that can not be changed, which makes the activation of
manoeuvres by different transmitters of any brand or model impossible.
2.2 APPLICATIONS AND USE CONDITIONS NOT PERMITTED.
This radio remote control can not be installed in applications in which:
- EXPLOSION-PROOF characteristics are required.
- The movement and/or lifting of persons is made and safety features greater than "PL e" are required on the
STOP command and "PL d" on the UMFS safety function on movements controlled by the Joysticks.
- An alternate current power supply to the receiver and outputs is required.
- Galvanic isolation of the power supply circuit or of the devices connected to the outputs is not guaranteed
when compared to the possible power supply in alternate current.
- The loss of the radio link and the relative shutdown of the receiver outputs may generate dangerous situations.
- The risk analysis has given a negative result.
- Doubt concerning the operation of the radio remote control remain.
