The RFI spring plate sitting on the board connectors is very sharp! Be careful, not to cut yourself, when removing it from the old board an sliding it onto the new board.

In most cases the RFI spring plate (Radio Frequency Interference spring plate, prevents radio emissions from the instrument to ambient) remains on the interface connectors of the board. Carefully remove the spring plate from the old board and slide it onto the new board before installing the board in the pump (the RFI spring plate is NOT part of an exchange board).

If you have to exchange other parts also, continue with that work, first.

On the new board check the switch setting of address switch S1, see “Setting the 8-bit Configuration Switch” on page 223.

An incorrect switch setting (e.g., TEST/BOOT) may cause the pump to turn

 

into a basic mode (yellow or red flashing status light). In such a case turn off

 

the pump, re-set the address switches, and turn on the pump again.

 

 

8Install the new board and reconnect the connectors. Make sure that the board is fitted correctly in the board recess holes at the rear panel.

9Refit the connector screws, and reconnect all connectors. Ensure the connectors are seated securely.

10Replace foam and top covers, see “Replacing the Top Cover and Foam” on page 156.

11Reinstall the pump in the stack. Reconnect all cables. Turn on the quaternary pump. If pump status indicator turns red continue with the section “Entering the Type Command”, otherwhise continue with “Entering the Serial Number” on page 135.
