6.5 ASSEMBLY REMOVAL AND REPLACEMENT

This section provides general information concerning the replacing of assemblies. Removal and replacement of assemblies is easily accomplished with standard hand tools. Section 4.4.4 describes repositioning and removal of the digital meter. This procedure is also used for meter replacement.

NOTE

If the transmitter (Controller version) is controlling a process, use the proper procedures and shut down the process.

6.5.1 Electronics Module Removal and Replacement

The Electronics Module should be returned to the factory for repair if found to be defective.

REMOVAL

1.The electronics module can usually be replaced at the installation site; otherwise, remove the transmitter for bench servicing.

If a Transmitter-Controller is controlling the process, use the proper procedures and shut down the process. Turn off power to transmitter and remove the enclosure cap to access the electronics module.

2.Retrieve the wrist strap from the maintenance kit and snap it on. Connect ground clip to unpainted area on the transmitter or mounting bracket. Use proper handling procedures to prevent damage to the Electronics Module from electrostatic discharge. Store an electronic assembly in a static shielding bag.

3.If a Digital Meter is installed, remove the meter assembly as described in Section 4.4.4. Disconnect digital meter board cable from Module connector P2. Retain removed cable.

Place digital meter assembly in static protective bag.

4.As shown in Figure 4-9, unscrew captive screw from Module’s retaining bracket. Slide Module forward until Module’s guide blocks are free of the metal guide posts. Place removed Module in static protective bag.

REPLACEMENT

1.Remove replacement Electronics Assembly from static protective bag. Refer to Figure 4-9 and check that Push Button Enable/Disable jumper W1 is in the Enable position.

2.If a Digital Meter is to be installed, refer to section 4.4.4 and connect the removed digital meter board cable to the Electronic Module’s P2 connector.

3.Carefully insert the Electronic Module into the housing.
