Installing Atlas 9800 CPU Board (M06333KXXXX)
To install the Atlas 9800 CPU Board, proceed as follows:
Always remove AC power from the pump/dispenser before servicing the unit. Failure to
turn off the unit before servicing may result in serious injury or death.
WARNING
1 Check the existing power supply. If the existing supply is not a M07588A00X Assembly, it
must be replaced. For details, refer to
“Installing Atlas 9800 Power Supply (M07588A00X)”
on page 10 .
2 Ensure that the AC power to the pump/dispenser is disconnected. Remove the DC cable from
the P1 Connector on the power supply.
3 If the pump/dispenser does not have ATC installed, proceed to step 4 . If the pump/dispenser
model is one of the following - 9850A/Q, 9850K, 9852A/Q, 9853A/Q, 9840A/Q, the ATC
support bracket (that holds the ATC black box) must be replaced. Use the M08218K001 Kit to
install the new bracket.
4 If the pump/dispenser has a RS-485 or Pulse-out I/F Board, remove the screws that secure the
I/F board and disconnect it from the existing CPU Board.
5 Disconnect all cables going to the connectors on the CPU Board. Ensure that you note the
connectors and cables so that they can be reconnected to the correct connector.
6 Unscrew and remove all the screws securing the CPU Board. Retain the screws for installing
the new CPU Board.
7 Remove the CPU Board. For models with plastic standoffs, carefully unsnap the CPU Board
from the standoffs and remove it. Remove any standoffs that may have remained on the CPU
Board and place them back into the plate where the board was mounted.
8 The new CPU Board (M06333KXXXX) can be configured for various operating conditions
using the jumpers JP1 to JP9. Check these jumpers and change, if required. Jumper settings
must be changed with the power to the pump/dispenser “Off”. CPU Board only reads new
jumper settings during power up.
