Access keys are used to unlock the doors. 

Only when the door is closed again
and the security key is reinserted can
the access key be taken out again. 

When both access keys have been
inserted back into the key switch,
the machine can be restarted. 

Machine Guarding
Machine guarding prevents physical
access to the guarded area. 

After the power is isolated, the solenoid from the key-switch gets de-energized and the access keys are released. The fully mechanical door locks are opened with these access keys. The door interlock is provided with a personal security key which must be taken with you into the robot cell (mandatory key removal) to prevent a restart in accordance with ISO 14118.

Troax machine guarding has been developed to safeguard robots and has been tested to withstand an impact of 1600 Joule.
