  • 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.

MOUNT, WIRE, AND SEAL THE SWITCH
WARNING
IMPROPER OPERATION

  • Ensure the switch actuator achieves sufficient travel for the 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 AlA, A1B, A5A, A5B) (Figure 3):
    – Ensure flats of switch shaft engage a 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 the 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].
