  • Consult with local safety agencies and their requirements when designing a machine-control link, interface, and all control elements that affect safety.
  • Strictly adhere to all installation instructions.
  • Failure to comply with these instructions could result in death or serious injury.
  • Ensure switch actuator achieves sufficient travel for positive opening of normally closed (NC) contacts to occur.
  • Failure to comply with these instructions could result in death or serious injury.
  1. Refer to:
    • Page 5 for adjustments.
    • Pages 9 to 18 for specific travel distances for each switch code, and specifications.
    • Page 5 proper application of limit switches, and switch mounting dimensions.
  2. Perform adjustments (if desired):
    • Head orientation, page 5.
    • Actuation direction (Figure 2, page 5).
    • Side rotary switches with 90* positive drive levers
    (catalog listings ending in A1A, A1B, A5A, A5B) (Figure 3):
    – Ensure flats of switch shaft engage groove in actuator lever.
    – Tighten locking screw (A) until tab (B) no longer moves.
  3. Mount switch using four M5 or #10 screws. Torque screws to 4,9 Nm to 5,9 Nm [43 in-lb to 52 in-lb].
  4. Remove screws on cover plate.
  5. Connect stranded wire (0,75 mm2 to 2,5 mm2, 18-14 AWG) or solid wire (0,75 mm2 to 1,5 mm2, 18-16 AWG) to connector terminals (use 90 *C wire when ambient temperature is over 75 *C). Torque switch terminal screws to 0,8 Nm to 1,0 Nm [7 in-lb to 9 in-lb]. Wire strip length should be 7,3 mm [0.29 in] max.
  6. Seal conduit opening according to instructions in PK 80112.
  7. Reassemble cover plate, and torque cover screws to 0,5 Nm [4.4 in-lb].
