3 Overview
Safe Lock is a security product equipped with a safety switch to prevent entrance to a
machine installation when the machine is still running.
NOTE! The safety switch comes in many different versions. This documentation does not
describe your specific switch. For information about your switch, see the included
documentation from the safety switch manufacturer.
This installation guide describes the 3 and 4-states Safe Lock. The difference between the
two is described below. NOTE! This is the Gunnebo Troax way of describing 3 and 4-states
Safe Lock.

State 4
Door closed. Lever in position locked and closing is detected by the safety switch.
Solenoid in the switch holds key and prevents opening.
The door can only be unlocked after completion of an external action, such as the
end of the machine sequence, or once a machine’s momentum has been
dissipated. The unlocking of the door is conditional.
3.1 Safety Instructions
Caution! It is important that you read the safety instructions (below) before installing the
Safe Lock. Follow all instructions carefully to avoid personal injury or damage to the Safe
Lock.
To prevent the Safe Lock from being tampered with, the lock must be fixed with blind rivets
and the switch and key fastened with security screws (one-way screws or Torx screws with
pins).
To work safely in the machine installation, block the Safe Lock with a padlock. The padlock
prevents the door from being closed and locked by someone else. There can be up to three
different persons inside the machine installation at the same time. Each person has his/her
own padlock. NOTE! The padlock is not included in the delivery.
