Analog Interface PCB
The Analog Interface PCB (AMETEK Part #591210901) is located on top of
the MCU PCB at the front of the electronic module (Figure 8-9).
Removing the analog interface PCB
• Remove the four knurled screws that hold the board in place.
• Unplug the connectors attached to the board (Figure 8-10).
• Carefully, lift the board until it slides free of the connector.
Replacing the analog interface PCB
• Position the new analog interface PCB on the connector and press
firmly to insert.
• Replace the screws removed earlier. Do not overtighten.
• Plug in the analog interface board connectors.
MCU PCB
The MCU PCB (AMETEK Part #59130901) is located below the Analog
Interface PCB (Figure 8-6).
Removing the MCU PCB
• Remove the analog interface PCB as described in the previous section.
• Using a 1/16” hex wrench, remove the four standoffs that hold the
MCU board in place. Unplug all connectors (Figure 8-11).
Replacing the MCU PCB
• Install the new MCU PCB on the mounting plate using the four stand-
offs removed and a 1/16” hex wrench.
• Remount the analog interface PCB as described in the previous sec-
tion.
