Gauges, Pipe Plugs, or Tire Valves
Depending on the options ordered, the DVC6000 SIS
digital valve controller 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 8-5). 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 figures 8-1
through 8-5 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 anti-seize (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
For DVC6010 SIS, DVC6020 SIS, DVC6030 SIS,
and DVC6005 SIS
Refer to figures 8-1 through 8-4 for key number
locations.
The terminal box is located on the housing and
contains the terminal strip assembly for field wiring
connections.
Note
This procedure also applies to the
DVC6005 SIS remote terminal box.
Removing the Terminal Box
WARNING
To avoid personal injury or property
damage caused by fire or explosion,
remove power to the instrument
before removing the terminal box
cover in an area which contains a
potentially explosive atmosphere or
has been classified as hazardous.
1. Loosen the set screw (key 58) in the cap (key 4) so
that the cap can be unscrewed from the terminal box.
2. After removing the cap (key 4), note the location of
field wiring connections and disconnect the field wiring
from the terminal box.
3. Separate the module base from the housing by
performing the Removing the Module Base procedure.
4. Remove the screw (key 72). Pull the terminal box
assembly straight out of the housing.
5. Remove two wire retainers (key 44), internal and
external to the terminal box.
Replacing the Terminal Box
Note
Inspect all O-rings for wear and
replace as necessary.
1. Install two wire retainers (key 44), internal and
external to the terminal box.
2. Apply silicone lubricant to the O-ring (key 35) and
install the O-ring over the stem of the terminal box.
3. 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).
4. Connect the terminal box connector to the PWB
assembly (key 50). Orientation of the connector is
required.
5. Reassemble the module base to the housing by
performing the Replacing the Module Base procedure.
6. Reconnect the field wiring as noted in step 2 in the
Removing the Terminal Box procedure.
