SAFE REST
INTELLIGENT DOUBLE CHANNEL
PROXIMITY DETECTION SYSTEM
Product description
SAFE REST: it is an "intelligent" electronic unit that replaces traditional mechanical or magnetic proximity or end of stroke switches, used to detect boom end positions on cranes, aerial platforms or suspended bridges. It is made of a codified transponder and a base unit. This makes impossible any override by the user, because of the unique communication codes between the two units.
SAFE REST: it manages the stabilizers logic enable according to European norm EN954-1 level III and EN 280, thanks to its double microprocessor and internal relays.
It is provided with CAN-BUS output, and it can be connected into an exiting CAN-BUS network for a machine global control.
