12.1 Purpose
The product
is designed to allow a trained operator to access a closed secure area in “monitoring-diagnostic” mode
while holding a transmitter equipped with an emergency stop system.
12.2 Need
A maintenance operator may need to intervene (1) in a dangerous area where a load transferring machine is
operating in automatic mode. This intervention may be aimed, for example, at determining the cause of a random
fault or detecting a malfunction, or visually inspecting products manufactured without stopping the automatically-
controlled system.
The operator’s safety is ensured by an individual portable protection device (transmitter) equipped with an
emergency stop palmswitch enabling him to stop the machine should he find himself in a dangerous situation.
