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 additional information, refer to
“Installing Atlas 9800 Power Supply
(M07588A00X)” on page 5-32 .
2 Ensure that the AC power to the pump/dispenser has been 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 model of the
pump/dispenser 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 kit
M08218K001 to install the new bracket.
4 If the pump/dispenser has an RS-485 or Pulse-out Interface Board, remove the screws that
secure the interface board and disconnect it from the existing CPU Board.
5 Disconnect all cables going to the connectors on the CPU Board. Ensure that you take note of
connectors and cables so that they can be reconnected to the correct connector.
6 Unscrew and remove all the screws holding the CPU Board. Retain the screws for installing
the M06333KXXXX 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 M06333KXXXX CPU Board can be configured for various operating conditions using
the jumpers JP1 to JP9 and Switch SW2. Check these jumpers and switch settings and change,
if required. Jumper settings must be changed with the power to the pump/dispenser “Off”. The
M06333KXXXX CPU Board only reads new jumper settings during power-up. For detailed
information on Jumper and Switch Settings for the M06333KXXXX CPU, refer to
“Configuration Steps” on page 4-5 .
9 Set the new CPU Board on the standoffs. Reinstall screws removed in step 6 . For models with
plastic standoffs, ensure that the metal standoffs are under the mounting holes located between
P2 and P3, and the outside corner next to P5. Carefully push the new CPU Board onto the
standoffs before installing the screws.
10 Reconnect all the cables, P1 to P9, and P11, if applicable. Reconnect the DC cable to P10 of
the power supply.
