Number 1 or 2 on the receiving unit identifies respectively URX-1 and URX-2.
These receiving units are equipped with a safety function called SAFETY that protects the system
“radio remote control” from unintended movements, namely machine movements not
activated intentionally by the user, but by possible electrical or mechanical failure of the radio
remote control. Such safety function protects from failure the neutral (rest) position of the ac-
tuators in the radio remote control.
The SAFETY function is only active if both the wiring instructions in the technical
data sheet and the prescriptions for correct installation included in the following
manual are respected.
