1.5.2 Protection against unintended movements from the standstill posi-
tion (UMFS)
This safety function protects the system “machine+radio remote control” from un-
intended movements, namely machine movements not activated intentionally by
the user, but resulting from possible electrical and mechanical failure of the radio
remote control.
Such safety function checks the neutral (rest) position of the actuators that control
the machine's movements. Each time one of those actuators is operated, the
transmitting unit sends both the movement command and the “SAFETY” com-
mand. Depending on the specific application, outputs related to these commands
are wired in series; alternatively the SAFETY command's outputs drive the safety
device provided on the machine.
1.6 Identifying the radio remote control
The serial number (S/N) is the only reference to be used to uniquely identify the
radio remote control, both if maintenance is needed and when providing state-
ments to competent bodies.
The serial number (S/N) and other information regarding the radio remote control
are provided in some plates both on the transmitting and on the receiving unit.
These plates must not be:
- removed from their position (removal will invalidate the guarantee)
- altered or damaged (contact Autec for replacement).
