3. Separate the module base from the housing by performing the Removing the Module Base procedure.

4. Disconnect the terminal box wiring connector from the PWB assembly (key 50).

5. Remove the screw (key 72). Pull the terminal box assembly straight out of the housing.

Replacing the Terminal Box

Note

Inspect all O‐rings for wear and replace as necessary.

1. Apply lubricant, silicone sealant to the O‐ring (key 34) and install the O‐ring over the stem of the terminal box.

2. Insert the terminal box assembly stem into the housing until it bottoms out. Position the terminal box assembly so

that the hole for the screw (key 72) in the terminal box aligns with the threaded hole in the housing. Install the

screw (key 72).

3. Connect the terminal box wiring connector to the PWB assembly (key 50). Orientation of the connector is required.

4. Reassemble the module base to the housing by performing the Replacing the Module Base procedure.

5. Reconnect the field wiring as noted in step 2 in the Removing the Terminal Box procedure.

6. Apply lubricant, silicone sealant to the O‐ring (key 36) and install the O‐ring over the 2‐5/8 inch threads of the

terminal box. Use of a tool is recommended to prevent cutting the O‐ring while installing it over the threads.

7. Apply lithium grease (key 63) to the 2‐5/8 inch threads on the terminal box to prevent seizing or galling when the

cap is installed.

8. Screw the cap (key 4) onto the terminal box.

9. Install a set screw (key 58) into the cap (key 4). Loosen the cap (not more than 1 turn) to align the set screw over

one of the recesses in the terminal box. Tighten the set screw (key 58).

Troubleshooting

If communication or output difficulties are experienced with the instrument, refer to the troubleshooting chart in

table 6‐3. Also see the DVC6200 Technical Support Checklist on page 68.

Checking Voltage Available

WARNING

Personal injury or property damage caused by fire or explosion may occur if this test is attempted in an area which contains

a potentially explosive atmosphere or has been classified as hazardous.

To check the Voltage Available at the instrument, perform the following:

1. Connect the equipment in figure 2‐3 to the field wiring in place of the FIELDVUE instrument.

2. Set the control system to provide maximum output current.

3. Set the resistance of the 1 kilohm potentiometer shown in figure 2‐3 to zero.

4. Record the current shown on the milliammeter.
