RELAY SEAL

3. Position the relay (with shroud) on the module base. Tighten the four screws, in a crisscross pattern, to a final

torque of 2 NSm (20.7 lbfSin).

4. Using the Field Communicator, verify that the value for Relay Type parameter matches the relay type installed.

5. After replacing the relay and verifying the relay type, calibrate travel or perform touch‐up calibration to maintain

accuracy specifications

Gauges, Pipe Plugs, or Tire Valves

Depending on the options ordered, the DVC6200 SIS or DVC6205 SIS will be equipped with either gauges (key 47),

pipe plugs (key 66), or tire valves (key 67). Single‐acting direct instruments will also have a screen (key 236, figure 7‐3).

These are located on the top of the module base next to the relay.

Perform the following procedure to replace the gauges, tire valves, or pipe plugs. Refer to figure 7‐2 and 7‐3 for key

number locations.

1. Remove the front cover (key 43).

2. Remove the gauge, pipe plug, or tire valve as follows:

For gauges (key 47), the flats are on the gauge case. Use a wrench on the flats of the gauge to remove the gauge from

the module base. For double‐acting instruments, to remove the supply gauge remove one of the output gauges.

For pipe plugs (key 66) and tire valves (key 67), use a wrench to remove these from the module base.

3. Apply zinc based anti-seize sealant (key 64) to the threads of the replacement gauges, pipe plugs, or tire valves.

4. Using a wrench, screw the gauges, pipe plugs, or tire valves into the module base.

Terminal Box

Refer to figure 7‐2 or 7‐4 for key number locations.

The terminal box is located on the housing and contains the terminal strip assembly for field wiring connections.

Note

The DVC6205 SIS feedback connections terminal box (shown to the right in figure 6‐6) is not a replaceable part. Do not remove

the tamper proof paint on the screw.
