Trouble detection condition<\/td>– The scanner home sensor (PS21) is unable to detect the scanner located at its home position.

– The scanner home sensor (PS21) is unable to detect a scanner even when the scanner motor (M9) has been driven to move the scanner over the maximum travelling distance.

– The scanner home sensor (PS21) detects the scanner when the scanner has moved the maximum travelling distance from the position, at which it blocks the scanner home sensor (PS21).<\/td><\/tr>

  4. Check the connector between M9-BASEB CN9E for proper connection and correct as necessary.<\/li>
  5. Check the connector between PS21-BASEB CN8E for proper connection and correct as necessary.<\/li>
  6. Check CPUB for proper installation and correct as necessary.<\/li>
  7. PS21 I\/O check, sensor check
