INTRODUCTION
The LI25-2001 is an intrinsically safe and non-incendive loop-powered meter
approved for hazardous area locations. The LI25-1001 is a general-purpose
loop-powered meter for safe area applications. The four front panel buttons make
the setup and programming an easy task. Five digits, bar graph, engineering
units, and trend arrows provide a clear and attractive presentation of the process.
The square root and programmable exponent functions allow for conditioning of
signals from non-linear transmitters without adding external components to the
system and the convenience of scaling without a calibrated signal source make
the LI25 Series the ideal choice for process display applications.

SAFETY INFORMATION
CAUTION: Read complete
instructions prior to installation and
operation of the meter.
Installation and service should be performed only by trained
service personnel. Service requiring replacement of internal components must be
performed at the factory.
!
LI25-2001 installation must be performed in
accordance with Control Drawing QS301034-

INSTALLATION
There is no need to remove the meter from its case to complete the installation,
wiring, and setup of the meter.
Unpacking
Remove the meter from box. Inspect the packaging and contents for damage.
Report damages, if any, to the carrier.
If any part is missing or the meter malfunctions, please contact your supplier or
the factory for assistance.
Panel Mounting
Prepare a standard 1/8 DIN panel cutout – 3.622" x 1.772" (92 mm x
45 mm). Refer to Mounting Dimensions, page 23 for more details.
Clearance: allow at least 4" (102 mm) behind the panel for wiring.
Panel thickness: 0.04" - 0.25" (1.0 mm - 6.4 mm).
Minimum steel/stainless steel panel thickness to maintain watertight rating:
0.06" (1.5 mm).
Note: A steel or stainless steel panel rather than plastic is
recommended in cases where a watertight or dust-tight seal is
required between the meter and the panel.
Remove the two mounting brackets provided with the meter (back-off the two
screws so that there is ¼" (6.4 mm) or less through the bracket. Slide the
bracket toward the front of the case and remove).
Insert meter into the panel cutout.
Install mounting brackets and tighten the screws against the panel. To
achieve a proper seal, tighten the mounting bracket screws evenly until
meter is snug to the panel along its short side. DO NOT OVER TIGHTEN,
as the rear of the panel may be damaged.

CONNECTIONS
Signal connections are made to a four-terminal removable connector. This section
is only intended for the LI25-1001.
LI25-2001 installation must be performed in accordance with Control
Drawing QS301034-1 in order to meet agency approval ratings.
Observe all safety regulations. Electrical wiring should be
performed in accordance with all agency requirements
and applicable national, state, and local codes to prevent
damage to the meter and ensure personnel safety.

4-20 MA INPUT CONNECTIONS
Input connections are made to a four-terminal connector labeled S+|S-|B+|B-.
The loop-powered backlight is an optional configuration and requires a total
maximum voltage drop of 5.7 V. The backlight is recommended for dim lighting
conditions and is enabled when wired as shown in Figure 3. It may be
bypassed if installed in bright lighting conditions to reduce the maximum
voltage drop to 2.0 V as shown in Figure 4.

SETUP AND PROGRAMMING
• There is no need to recalibrate the meter for
milliamps when first received from the factory.
• The meter is factory calibrated for milliamps prior to
shipment. The calibration equipment is certified to
NIST standards.
Overview
There are no jumpers involved in the setup process of the meter. Setup and
programming is done through the front panel buttons.
After all connections have been completed and verified, apply power to the loop.

Setting the Units Display (units)
The meter can be set to display a combination of three alphanumeric characters
for engineering units or for identification (eg. FT, IN, M, CM, GAL, L). There is
also a fourth alphanumeric character located above this row, which supports a
degrees symbol and “x10” symbol (eg. °C, °F, x103, x106, x109).
Preconfigured units are available for feet (FT), inches (IN), meters (M),
centimeters (CM), gallons (GAL), liters (L), percent (%), and
percent (PCT).

DataLoop™ LI25 Level Controller Instruction Manual

Programming the Meter (prOG)
It is very important to read the following information, before proceeding to
program the meter:
• There is no need to recalibrate the meter for milliamps when first received
from the factory.
• The meter is factory calibrated for milliamps prior to shipment. The
calibration equipment is certified to NIST standards.
• Use the Scale menu to enter scale parameters without applying a live
signal.
• Alternatively, use the Calibrate menu to apply a signal from a calibrator or a
4-20 mA transmitter to calibrate the meter.
The Program menu contains the Calibrate and the Scale menus. Inputs may be
calibrated or scaled to any display within the range of the meter.
Additional parameters, not needed for most applications, are programmed with
the Advanced features menu, see Advanced Features Menu, page 25.
Error Message (Error)
An error message indicates that the calibration or scaling process was not
successful.
After the error message is displayed, the meter reverts to input 1, allowing the
appropriate input signals to be applied.
The error message might be caused by one of the following conditions:
1. Minimum input span requirements not maintained.
2. Input 1 signal inadvertently applied to calibrate input 2.
Minimum Input Span
The minimum input span is the minimum difference between input 1 and input 2
signals required to complete the calibration or scaling of the meter. The minimum
span is 0.40 mA.

DataLoop™ LI25 Level Controller Instruction Manual
20 MN301034 rev D
Scaling the Meter (sCAlE)
The 4-20 mA input can be scaled to display the process in engineering units.
A signal source is not needed to scale the meter; simply program the inputs and
corresponding display values.
For instructions on how to program
numeric values see Setting Numeric
Values, page 17.
