Machine Safety with Double Door Scenes
Machine safety in logistics & distribution
Some guarded areas of production lines require the use of double doors, where an operator uses one door for entry and another to exit.
Access request and reset using ID-badges
Authorised access
Controlled access to machine with rundown time
amGard Pro
The safety switch can be opened from the inside or outside using the door handle.
FRANK Access Control
After logging in with the ID badge by the 1st operator, the safety switch is unlocked and the zone can be entered. The 2nd operator also logs in when entering the zone.
FRANK Access Control
Give pre-authorized employees access to the facility.
As long as the operators are not logged off
the installation cannot be started.
Only when all operators are logged off
and all doors are closed, it is possible to
to restart the installation. This means that it
does not matter it does not matter through
which door one enters This also means that
it does not matter which door one enters or
leaves the room through.
The FRANK system determines
which employees are authorized
and who is logged on and off
in the secured areas.
Machine safety regulations acknowledge the risk of entrapment and or accidental machine restsart using a double door system. By using the FRANK access control system in combination with safety interlocks these risks can be eliminated.
Access to the guarded area can be requested by an operator using his ID badge at the 1st access door. When the machine is isolated and the area is cleared for entrance the door can be opened. Only when the operator is logged out on the FRANK reader at the 2nd door and both doors are closed the production line can be restarted.
Access by multiple operators requires everyone to be logged out of the system before machine restart is possible.
Prevent unwanted restarts and lock-ins at double door systems with ProfiNet controlled ID badge reader and security locks.
