  1. Connect Safety Circuit to the Normally Closed contact (21-22). The Normally Open contact is for indicators, etc. When the activating rope is properly tensioned the Normally Closed contacts are "closed". If the rope is cut or pulled, the Normally Closed contact opens, turning "off" the machine control power.
  2. Mount the switch using tamper-resistant fasteners (not supplied). Always use washers under the switch mounting fasteners to prevent the fasteners from pulling through the switch mounting holes.
  3. Rope tensioning - see Figure 1.
    The rope is properly tensioned when the end of the indicator covers about half of the green collar. Once the activating rod is positioned, the "automatic reset" types will automatically transfer the contacts into the "closed" position. To transfer the contacts in the "manually reset" types, pull out the "reset" knob.
  4. The contacts transfer if the activating rope is either cut or pulled. To reset the switch reset the rope tension as described in Item 3 above.
  5. Do not use the switch as a mechanical stop.
  6. Verify proper operation of the Safety Switch before placing the machine in service.
