SBX-65 Ionization Unit Field Test

1. Disconnect and remove all power to the unit by turning the circuit breaker off.
   Turn the POWER SWITCH on the unit to the "off" position.
   Turn the ION OUTPUT CONTROL off. (full CCW)
   Put the test/operate jumper (W1/W2) in the “test” position on the main circuit board.
   Disconnect the wires at the electrodes. Do not let them touch ground or each other.
   
   
2. Verify the fuse on the front panel is good.
   Verify the 115/220 Jumper (JP1) is set for the proper input voltage.
   


3. Turn the circuit breaker on and apply power to the unit.
   
   
4. Verify the presence of input power at the terminal block in the enclosure on pins 1 and 3.
   
   
5. Turn the power switch on.
   The “Power Monitor” is illuminated. It should change color about every 9 seconds.
   The CHECK ELECTRODES and ION OUTPUT lights should not be illuminated.
   
   
6. Short the electrode leads from the unit with a pager clip of jumper wire.
   Rotate the ION OUTPUT knob to 30%.
   The ION OUTPUT light should illuminate.
   Keep the leads shorted for less than 15 seconds!



7. Remove the short between the electrode wires (this leaves an "open" between the two electrodes) - the CHECK ELECTRODES light should illuminate.
   The ION OUTPUT light will not be illuminated.



8. Turn the power off.
   
   
9. Reconnect the wires to the electrodes.
   Rotate the ION OUTPUT knob to 0%.
   Return the TEST/NORM jumper to the normal position.
   
   
10. This completes the field test of the SBX-65.
