• Analog Interface Assembly
• Power Supply
• Fan
• Pilot Valve Manifold
Removing the Electronics Module From the 3050-RM
Disconnect all power to the analyzer before removing the Electronics
Module.
Tools Required
• 1/4-inch nut driver
• 1/16-inch hex wrench
• Phillips and slotted screwdrivers
Procedure for Removing the Electronics Module
Use Figure 4-9 as a reference for locating the items described in this procedure.
• Locate the four (4) Phillips head screws on the Electronics Module.
• Using the appropriate tool, remove the mounting hardware.
• With all the interconnecting wiring and tubing still attached, remove the
Electronics Module from the 3050-RM Enclosure by pulling up and slightly
towards the front of the analyzer.
• Once you remove the Electronics Module from the 3050-RM Enclosure, you
can place it on the 3050-RM Enclosure as a resting xture. However, take
care not to scratch the 3050-RM Enclosure with the Electronics Module (a
piece of cardboard can be placed under the Electronics Module to protect
the enclosure).
All of the components are now accessible for maintenance or replacement.
