6809 Controller: Adding a UPS

These procedures describe how to connect an uninterruptable power supply (UPS) to the 6809 phototherapy system controller.

Tools required

• Phillips-head Screwdriver

Procedure

IMPORTANT: Always Disconnect Power from the System when Servicing.

1. Remove the four screws which hold the black plastic bezel of the controller to the housing and completely remove the bezel from the unit.
2. Remove the spacer bars on each side of the metal housing so that the controller can slide out of the metal housing brackets. Pull from the top and let the controller lay face down on housing exposing the back.
3. Remove the orange connectors at the bottom the controller (usually there are 8) by firmly grasping the connector and pulling up on it at a 90 degree angle from the circuit board.
4. At this point, two black pig-tail fuse connectors should be the only remaining connectors to be removed so that the entire controller will be free of the machine. To loosen these connectors, simply grab each fuse holder at its ends, compress slightly, and twist counter-clockwise. A 1/2 amp fuse will be removed from each and should be retained for re-installation.
5. With the controller completely removed from the unit, the existing power supply is easily visible and ready to be removed. The power supply board has the #1 and #2 orange connectors attached. Remove the bracket by loosening the three screws securing it to the control and remove the #1 and #2 connectors.
6. Mount the new UPS bracket onto the controller by installing the three screws which once held the old power supply. The new UPS should be mounted with the two white headers facing the #1 and #2 connectors so that they may be plugged onto these headers labeled J1 and J2.
7. With the new UPS secured onto the controller, plug in the two orange connectors placing the connector labeled 1 onto the white header labeled J1 and the connector labeled 2 onto the header labeled J2.
8. Having completed the last step, the controller is ready to be installed back onto the unit. Put the fuses back into the holders and reconnect the fuse holders.
9. Replace all the orange connectors and place controller back into the mounting bracket. Replace the spacer bars leaving the screws on the spacer bar loose so that the controller can slide in the brackets.
10. Replace the black plastic bezel over the controller and insert the 4 screws to hold it in place. Push the bezel firmly to the machine so that it is touching the cover of the unit and tightened all four screws.
11. Installation of the UPS power supply is now completed. Reapply power to the unit and the display should then be lit.
12. Enter the correct time and date and unlock the controller with user password. The machine should now be ready to administer treatments once again.
13. In the event of a power failure the control should maintain the display for up to an hour, drawing power from the UPS. When the UPS has exhausted its reserve the display will shut down and remain off until power is restored to the unit. The controller will still retain its memory after the display has gone off, but will need to have the correct time and date entered once the main power has been restored to the unit.
