REPLACING A PC (PUMP CONTROL) PCB
Remove Old PCB
1. Disconnect all cables from the inoperable PC PCB. It may be necessary to remove the
ribbon cable from all of the other PC PCBs to allow clearance for removal of the inoperable
PC PCB.
2. Remove the two screws which secure the PC PCB to the PCB Support Bracket. Slide the
PC PCB forward and out of the support bracket.
Install New PCB
3. Verify that the jumper configuration of the new PC PCB is set up correctly. See page 2-19
for jumper explanations and locations or simply set the new PC PCB jumpers to match the
jumpers on the inoperative PC PCB.
4. Slide the new PC PCB back into the PCB Support Bracket and secure it with the two screws
which were removed in Step 2.
5. Reconnect the three cables to the rear of the PC PCB. Reconnect the ribbon cable to the
front of the PC PCB and verify that the cable is securely connected to each PC PCB in the
Series 1000.
