Installation 

 

1.9 

The electronic housing can be rotated to adjust the digital display on a better position. To rotate it, 
loose the Housing Rotation Set Screw, see Figure 1.4 (a). To prevent humidity entering, the electric 
housing and the sensor joint must have a minimum of 6 fully engaged threads. The provided joint 
allows 1 extra turn to adjust the position of the display window by rotating the housing clockwise. If the 
thread reaches the end before the desired position, then rotate the housing counterclockwise, but not 
more than one thread turn. Transmitters have a stopper that restricts housing rotation to one turn. See 
Section 4, Figure 4.1.

Wiring 

 
To release the cover that gives access to the wiring block, turn the cover locking screw clock wise, see 
the direction of the arrow in the figure 1.4. 
 

Test

 and 

Communication terminals

 allow, respectively, to measure the current in the 4 - 20 mA loop, 

without opening it, and to communicate with the transmitter. To measure it, connect a multimeter in the 
mA scale in the "

-

" and "

+

" terminals, and to communicate, use a 

HART

 configurator in the "

COMM

" 

and "

-

" terminals. The wiring block has screws on which fork or ring-type terminals can be fastened. 

See Figure 1.6. 
 

 

 
 

Figure 1.5– Wiring Block 

 

The 

LD291

 is protected against reverse polarity 

 

For convenience there are two ground terminals: one inside the cover and one external, located close 
to the conduit entries. 

 

Use of twisted pair (22 AWG or greater than) cables is recommended. Avoid routing signal wiring close 
to power cables or switching equipment. 

 

The Figure 1.6 shows the correct installation of the conduit, to avoid penetration of water, or other 
substance, which may cause malfunctioning of the equipment.
