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 DVC6200f 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 8‐3). 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 8‐2and 8‐3 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.
