COMPONENT REMOVAL AND REPLACEMENT
Note the wiring connections, wire colors, rotary dial positions and RS485 jumper positions when replacing boards.
These must be replaced exactly as they were. If in doubt, refer to the INFO CARD on the cabinet door or the
appropriate wiring diagram provided in this manual.
PC 270 HIGH INTENSIT Y POWER CONVERTER
PCB1 (F2161000 PCB FH CONTROLLER HIGH INTENSITY)
Remove:
1)
Unplug all wire connectors.
2)
Loosen seven Phillips-head screws which hold the PCB in place.
3)
Slide the board to the left and then lift the board out of the enclosure.
Replace: Reverse the removal procedure.
Connect the Ribbon Cables on J6, J7 and J8 to J1 of the corresponding order of PCB2 (J6 to PCB2 #1, J7 to
PCB2 #2, J8 to PCB2 #3).
Connect PB1’s J1 to J2 of PCB3 CAP #1.
Connect all 3 connectors for the RED OUTPUT at J3. Be sure that the BLK/RED wires are connected to J3.
Connect all 3 connectors for the IR OUTPUT at J5. Be sure that the BLU/BRN wires are connected to J5.
RS-485 communication wires must be connected to J4.
AC input power wires must be connected to J2.
Set rotary dials appropriately
PCB2 & PCB 3 (F2165000 - PCB FTB 270 HILED BCN DRIVER, F2165500 - PCB FTB 270 HILED BCN
CAPACITOR)
Removal procedure:
1)
Unplug all wire connectors.
2)
Loosen three Phillips-head screws, which connect the driver assembly to the backplate of the
enclosure.
3)
Slide the bracket up and then lift the bracket with the boards out of the enclosure.
Replacement procedure: Reverse the removal procedure.
When replacing assembly #1 (the left-most set), be sure to reconnect J2 to PCB1’s J1.
PCB4 POWER SUPPLY (F5370800 - POWER SUPPLY 320W 54V 6A)
Removal:
1)
Turn off input power by switching the Circuit Breaker on TB1 to the OFF position (GREEN).
2)
Remove the bracket for PCB1, by first following the procedure for disconnecting the wiring harnesses to
PCB1, then loosening the 4 screws retaining PCB1 and sliding the bracket down to remove the bracket.
3)
Disconnect the input power lead to the power supply by removing GRN, BLU, BRN wires from the top half
of TB2.
