Contact Edge with 10K Resistor Monitoring

1. Verify that dip switch DS2 switch 4 (contact edge monitor) is ON pressed down on the right hand side.
   
2. Press and hold the LED indicator on the control board.
   
3. Verify the D5 LED (Contact edge 2nd entrapment) located bottom left corner of the control board is ON dimly.
   
4. If not using a DC voltmeter measure the voltage on J2 pin 6 to ground reading should be approx. 2.5 Vdc.
   
5. Activate the contact edge by depressing it and verify the D5 LED is ON bright now or the voltage drops to 0 Vdc.
   
6. If reading is 5 Vdc then check wire connections from contact edge for proper connection.
   
7. If wire connections are correct then disconnect the contact edge wires from the J2 connector.
   
8. Using an ohm meter verify the resistance measured between the 2 contact edge wires, should be 10K.
   
9. If not contact edge is bad.
   

Photo Eye N/C Contact Monitoring

1. Verify that DS1 dip switch 10 is ON press down on the right hand side.
   
2. Verify that dip switch DS1 switch 8 (photo eye monitor) is ON press down on the right hand side.
   
3. Turn dip switch DS1 3 and 4 OFF. Allows power to be applied to photo eye.
   
4. Press and hold the LED indicator button located on the control board.
   
5. Verify that D11 LED (Photo eye N/C 2nd entrapment) located bottom left corner of the control board is ON.
   
6. If not verify alignment between photo eye transmitter and receiver. Correct if necessary.
   
7. If not then check wire connection from photo eye for proper connection.
   
8. If D11 is ON verify that the D11 Led goes OFF when photo eye beam is broken.
   
9. If D11 does not turn OFF when beam is broken then photo eye is bad.
