7.2 Protective stop
Introduction
The FlexLoader Standard Safety handles protective stop and manual operation of
dangerous equipment. The protective stop mode ensures safe stop of equipment
upon cell entry and prevents the equipment from being started while the cell is
accessible.
Standard operation
The example below shows a typical operator panel made by an integrator, handling
entry request, door reset and restart. Only emergency stop, emergency stop reset
and door reset key switch interacts with the safety center.

DANGER
When entering the cell, the operator must bring the key that is used to confirm
the protection door. This is to prevent somebody else from confirming and
restarting FlexLoader Standard Safety Center when the operator is inside the
cell. There may only be one key for the entire cell.
Take the key (D) and carry out the work in the cell.
