Electrical interlocking of a robot cell

This example shows the safeguarding of robot areas in which amGard products offer a combined mechanical and electrical solution.

1. CPS2LOK024024B CLIN By pressing the access request button, the machine or installation is shut down, by the machine control system.
   
   The solenoid lock restricts the release of keys A until the guarded area or machine is safe to enter (indicated by the yellow status LEDs).
   
   Energising the solenoid breaks the dual safety circuits to prevent unexpected re-start.
   
   Both safety keys A can now be released indicated by the red status LED.
2. AM & SBNS1A1FOOT CLIN Keys A can be used to unlock the door locks and releases the safety keys B. These can be taken inside the guarded area to prevent personnel being trapped and/or an accidental machine restart.
   
   By reversing this compulsory procedure the machine can safely be restarted.

Safeguarding a packing line

This example shows the safeguarding of a potentially dangerous area with a teach mode function inside.

1. SBNLOK024024K CLIN Removal of the key from one of the pods at the doors selects machine stop at the end of a run down cycle. The solenoid is then energised, by the machine control system and access can be gained. The operator can take the safety key into the potentially hazardous area preventing restart.
   
   The operator can take the safety key into the potentially hazardous area preventing restart.
2. PODK CLIN By inserting one of the keys in the stand alone pod inside the guarded area safe programming can be initiated.
3. SBILOK024024IRK CLIN The LOK internal release option can be used to unlock the door from inside a guarded area should personnel become trapped; by pushing the button on the rear of the unit the tongue is released from the actuator head and the door can be opened from the inside.
