Wiring Diagram
To install:
1. Align the Modulevel process connections with those on the
vessel and attach accordingly, based upon the connection
type. Appropriate gaskets and bolting will be required for
flanged connections. Install the flange bolts and nuts and
tighten alternating nuts in a star pattern. Flange bolting
torque specifications are listed on page 12.
NOTE: It is recommended that shut-off valves be installed in each
equalizing line to the chamber, along with a drain valve (refer to
Figure 8). Equalizing lines should be sized at least as large as
the connections provided at the chamber.
2. Make sure that the chamber is vertically level within 3° in
each direction to ensure frictionless operation of the internal
displacer.
Caution: All Modulevels are shipped from the factory with the
enclosing tube tightened and the transmitter head set
screws locked to the enclosing tube. Failure to loosen the
set screws prior to repositioning the supply and output con-
nections may cause the enclosing tube to loosen, resulting
in the possible leakage of the process liquid or vapor.
3. Loosen the transmitter head lock screws (socket type) and
position conduit outlet in the desired direction. See Figure 8.
4. Retighten lock screws.
NOTE: Since the transmitter head is rotatable through 360º, it is impor-
tant to make certain that the controller locking screws are tight
before making electrical connections.
3.5 Wiring
Caution: FOUNDATION fieldbus E3 Modulevel transmitter operates at
voltages of 9–32 VDC. Higher voltage will damage the
transmitter.
Wiring between the power supply and the E3 Modulevel
transmitter should be made using minimum of 18 AWG
(+)
(-)
shielded twisted pair instrument cable. Wiring must be suit-
able for temperatures up to at least +85° C. Within the
transmitter enclosure, connections are made to the terminal
strip and the ground connections. When installing a remote
mount E3 transmitter, refer to Figures 12 & 13 for wiring
connections.
WARNING! Explosion hazard. Do not disconnect equipment unless
power has been switched off or the area is known to be
non-hazardous.
