    Wiring/Installation Wiring  Wiring Precautions Apply double or enhanced insulation from hazardous voltage to all input and output lines. Failure to do so may result in electric shock. Connect the load between the output and +24 V line (NPN output). Connecting the load between the output and 0 V line will result in a dangerous condition because operation is reversed to "ON when blocked".

    Checklists Pre-Operation Checklists Make sure to test the operation of the F3SJ-E/B after installation to verify that the F3SJ-E/B operates as intended. Make sure to stop the machine until the test is complete. Unintended function settings may cause a person to go undetected, resulting in serious injury. After installation, the highest level administrator must use the following checklist to verify the operation, placing a check mark in each of the boxes.
  • Page 123 Checklists Power supply's +24 V must be grounded. Wiring must not be bent, cracked, nor damaged.  Operation check while the machine is stopped The test rod is not deformed. Use a test rod with an appropriate diameter for inspection. The sensor can detect a test rod wherever it is in the detection zone.

  • Page 124: Maintenance Checklists

    Checklists Maintenance Checklists Perform daily and 6-month inspections for the F3SJ-E/B. Otherwise, the system may fail to work properly, resulting in serious injury. Do not try to disassemble, repair, or modify this product. Doing so may cause the safety functions to stop working properly.
  • Page 125 Checklists The test rod is detected when it is moved around in the detection zone as shown in the diagram below. In other words, when a test rod is inserted into the detection zone, the stable-state indicators (STB) turn off and the ON/OFF-state indicators turn red. Start Stop When muting function is used, installation condition of muting sensor must not be changed.
