DESCRIPTION

The LI2X 31/2 digit loop-powered meters are
perfect for applications where a simple,
inexpensive display is required and no AC
power is available.And even if the lighting is
poor, the loop-powered backlighting option lets
you see the display under any lighting condition.
This option gets its power from the 4-20
input loop so there is no need for additional
wiring and no batteries to ever change.The
LI2X is housed in a NEMA 4X enclosure, so
it can be installed in just about any non­hazardous area in the plant.

SETUP

The only tools needed for calibration are a calibrated current
source and a screwdriver.

DISASSEMBLY

The removable screw terminal connector is located on the
lower circuit board.To access these input terminals it is
necessary to remove the display board from the input signal
board.This is done by first removing the enclosure cover.
Next,

loosen the 2 screws that hold the display board to the
standoffs. Rotate the display board so the right side comes
off the standoff
from both standoffs. Be careful to avoid contact of the display
with rough surfaces.The display board may be disconnected
from the ribbon cable simply by pulling up on the ribbon
cable connector located above the display.Connect a
mA input signal to terminal J5 located on the input signal
board as shown below. When re-assembling the circuit
boards be careful NOT to over-tighten the screws.

first, proceed to remove the display board

INSTALLATION

Installation of the LI2X involves removing the display board
and screw terminal connector.It may also be necessary to
remove the input signal board depending on type of conduit
hubs used.

CONNECTIONS

DECIMAL POINT SELECTION

The decimal point jumper array (JP1) is located to the upper
right corner of the display board. Place a jumper across the
bottom pins for a display of 199.9, across the middle pins for
a display of 19.99, and across the top pins for a display of

1.999

CALIBRATION

The LO calibration control (R11) is located below the display
and the HI calibration control (R9) is located to the right of
the display. Apply a 4 mA input signal and adjust the LO
control to display the desired reading. Next, apply a signal
between 16 and 20 mA and adjust the HI control to display
the desired reading. Complete the calibration procedure by
making any minor adjustments to the LO and HI controls.
