I am working on a very large machine at the present time. This machine has several safety zones and up to 8 light curtain guarded areas. It is divided by these safety zones to allow operators to enter certain areas during certain times. It has muting circuits where an operator can press "Mute" enter a zone and if he leaves the zone and presses "Reset Button" the machine doesn't have to completely stop. However if he is still in that zone when operations begin in that area then we stop that section of machinery,. This is done quite regularly throughout the industry.
NOW MY ISSUE:
This customer has requested I design a safety system that works like this:
As operator(s) enter a zone they must step on a sensing mat. The safety system counts the number of people who enter that zone. Now when they leave the safety system counts how many people left that zone. And when (By Counting) everyone has left the zone the machine can continue with operations in that area.The Ingress or Egress is determined by the operator(s) hitting a button.
My concern is there is nothing to prevent an operator just stomping the mat several times and thus allowing someone to remain behind.
I am fighting this every way possible. But I Need AMMUNITION to fight it with. I realize the customer / end user is responsible for safety, However when an injury occurs as we all know The lawyers sue everybody involved.
