1.0 Overview
The LCI-100 Line Control Instrument is a versatile instrument that displays line Tension, Payout,
and Speed for winch and wire rope applications. Signals from Tension and Payout sensors are
converted into engineering units and displayed on a high visibility electro-luminescent display.
The display and the five front panel keys underneath it allow the operator to acknowledge alarms
and to manipulate the calibration and configuration menus. The function of each key is indicated
by the label that appears immediately above it in the Display. As the operator navigates through
various displays the functions of these keys and their associated labels will change. The LCI-100
can be user configured to accept inputs from a range of Tension and Payout sensors, display the
parameters in different locations and resolutions, enable as many as six different alarms, and select
a variety of serial communication options.
This manual is intended to cover the installation, set-up, and operation of the LCI-100 and the
LCI-90R remote display.

2.0 Quick Start
This section provides a subset of the full technical manual to facilitate installation and start-up of
the LCI-100. For a complete technical description please refer to Sections 3.0-6.0.
2.1 Mounting
The LCI-100 will fit in a 9.25 x 7.00” cutout, with a minimum of 5.5” depth clearance (see
Appendix A for dimensional drawing). The instrument is held in place with removable
panel clamps that screw to all sides of the display. Four clamps are included with each
display.
After sliding the display into the cutout, screw the four panel clamps on the sides of the dis-
play, with the flanged end of the clamp toward the panel, using two 10-32 machine screws
per bracket. Once the panel clamps are installed, tighten the jackscrews against the panel to
compress the LCI-100 gasket to seal against the panel. Lock the jackscrews with hex nuts
to prevent them from vibrating loose over time.
2.2 Basic Field Wiring
Basic field wiring connections for the LCI-100 are those required for power, the force
transducer, and the quadrature Payout sensors. The base unit LCI-100 (i.e. no options) is
shipped with hardware settings to accommodate the following field devices: one 4-20 mA
Tension signal and two PNP proximity switch inputs for Payout. The LCI-100 can be
connected to a broad range of field sensors; wiring connections for these are explained in
detail in Section 4.0.
DC power (and serial communications) connections are made to the printed circuit board
directly behind the display. Tension and payout inputs, alarm wiring and analog outputs go
to quick-connect style terminal blocks on the “interface PCB”. These blocks are referenced
by both a label indicating the function (‘analog’, ‘digital’), and by an ID number (‘TB2’) on
the top of the block.
The connection diagrams for the factory standard power input, Tension and Payout sensors
are shown in the tables below. The LCI-100 terminal blocks are listed on the left by func-
tion and number, and the field devices are listed on the right.

2.3 Basic Hardware Configuration
The base unit LCI-100 (i.e. no options) will accommodate the field device wiring and input
devices shown in Section 2.2 above. No menu programming or hardware jumper changes
are necessary if these inputs are used. Setup procedures for alarms, analog outputs, input
isolation modules, and serial communication options are discussed in Sections 4.0-6.0.
2.4 Basic Operation
The LCI-100 base unit is configured at the factory to display Tension at the top of the
screen, both numerically and as an analog bar graph immediately underneath. Speed is
displayed in the middle on the left and Payout on the right, as shown on the cover. The
factory setting for units is pounds and feet. Tension and Payout have 0 decimal places,
while Speed has 1 (2 illustrated). Section 5.0 explains how to change these settings.
The calibration values for the Tension and Payout sensors must be set for each field applica-
tion. The following is a description of the simplest calibration for the anticipated sensors
described above. For complete instructions on the menu functions and calibration features
refer to Section 5.0.

Measurement Technology NW LCI-100 Operator Manual Page 9
To calibrate either the Tension or Payout sensors, just press the CALB button on the RUN
screen. This will bring up the 2.0 CALIBRATEdisplay. (Or press MENU to get the 0

3.0 Mechanical Installation
The LCI-100 is designed for mounting on the front-panel of an electrical enclosure with a suitable
environmental rating. The sealed front face of the LCI-100 is made of 12 gauge stainless steel,
and the slotted rear cage is designed to promote heat transfer, facilitate field wire terminations, and
provide a purchase point for the panel clamps. The front face is 8.0” high x 10.0” wide; the total
depth is 5.5”.
3.1 Environmental Considerations
The front face of the LCI-100 is designed for NEMA 4X applications. It consists of a 316
stainless steel top layer, a sealed lexan window, and five membrane-sealed stainless steel
push buttons. The rear cage is NEMA 1 and requires protection with a suitable enclosure.
A polyurethane gasket, held in-place by a high temperature adhesive is applied to the back-
side of the front face. When mounting the LCI-100 in open deck locations, a front-panel
cover is recommended to protect the unit when it is not in use.
The standard temperature range of the LCI-100 is –20°C to +60°C. The high temperature
(HT) model will operate in temperatures from –40°C to +75°C.
An optional rear enclosure is available to provide NEMA 4X protection for the instrument.
The NEMA 4X enclosure can be mounted with an adjustable gimbal bracket. Consult
factory for mounting information and temperature ratings.
3.2 Dimensions and Cutout
The LCI-100 will fit in a 9.25” x 7.00” cutout (tolerance –0.01, +0.100), with a minimum of
5.5” depth clearance (see Appendix A for dimensional drawing). The front panel can be up
to 5/8” thick.
3.3 Display Mounting
The instrument is held in place with removable panel clamps that screw to the 10-32
threaded inserts on all sides of the display. Four clamps are included with each display, but
the unit can be installed using as few as two if a panel seal is not required.
Two hole patterns are available on each bracket. The bracket that is used on the bottom
edge of the unit will need to use the holes that are located closer to the bend of the bracket.
The remaining three brackets use the two holes located farthest from the bend.
After sliding the display into the cutout, screw the four panel clamps onto the sides of the
display, with the flanged end of the clamp facing toward the panel. Once the panel clamps
are installed, tighten the jackscrews against the panel to compress the LCI-100 gasket to
seal against the panel. Lock the jackscrews with hex nuts to prevent them from vibrating
loose over time.

Measurement Technology NW LCI-100 Operator Manual Page 12
4.0 Options and Wiring Diagrams
The LCI-100 can be configured for a wide range of signal input and output functions. Each
of these functions requires the instrument to have the correct menu settings (Section 5.0),
hardware jumper settings (Appendix C), signal and power wiring, and in some cases,
optional I/O modules installed. The wiring diagrams are given in this Section; the optional
I/O modules are listed in Appendix D. The table below gives of a summary of the LCI-100
functions, referenced to their associated menu, required hardware options, and section of
this manual covering the wiring termination.

4.1.2 Tension Sensor Inputs
The Tension sensor analog inputs both isolated and non-isolated are terminated on
the bank of terminal blocks labeled Analog. The field wiring connects to the unit on
the rear and underside of the enclosure. Terminal blocks are referenced both by the
external label located underneath each bank of terminal blocks and by terminal block
numbers located on the top of the terminal block banks.

Measurement Technology NW LCI-100 Operator Manual Page 14
Isolated analog inputs require signal-conditioning modules. The optional analog
input modules (Appendix D) supply isolation and a variety of signal conditioning
options. The analog input channels 1 and 2 are factory configured to accept 4-20 mA
inputs while the remaining four channels are factory configured for 0-5 VDC voltage
inputs. The LCI-100 can accept six analog inputs, allowing the output from multiple
tension sensors to be summed. Each different input type requires a specific hardware
configuration setting (see Appendix C).
Tension sensors can be externally powered from the auxiliary DC output 24VDC
located on the barrier blocks mounted on the rear of the display. Option 43 must be
specified. The factory configuration internally connects the auxiliary DC output
COM to the CH (1-6) LO.
The LCI-100 can accept input from dual axis load pins on any two adjacent channels.
The first channel should be the x-axis input, the second channel should be the y-axis
input. Both channels must be configured for 2-AXISinput (see §6.3). Refer to §5.8
and §§14-15 (Appendices F & G) for more details about this configuration.

4.1.3 Count Sensor Inputs
The count sensor inputs are terminated on the Digital terminal block bank. The LCI-
100 can accept NPN and PNP type proximity and Hall-Effect inputs, as well as TTL/
CMOS encoder inputs. The input voltage thresholds are set to accommodate all these
ranges with no adjustment. These thresholds are 3.4 Volts for low-high transitions,
and 2.3 volts for high-low transitions.
Each different sensor type requires a specific hardware jumper setting on the inter-
face PCB (see Appendix B). The LCI-100 can accept two separate quadrature
inputs. Below are the wiring diagrams for the different sensor types with typical
excitation voltages.

4.1.4 Alarm Outputs
The eight alarm outputs are terminated on the Digital terminal block bank. The LCI-
100 requires optional SM-type optically isolated output modules to implement the
alarm outputs. These are available in both solid state and hard contact types with a
variety of voltage and current ratings. The wiring diagram below matches the Opto
Module number with the corresponding terminal block designation on the Digital
terminal block bank. Note that the Input Check alarm (§6.3.2) also uses Opto 1,
and the Shunt Cal relay (§4.1.5, §5.6) uses Opto 8.

4.1.5 Shunt Calibration
The LCI-100 provides a method for “shunt calibration” of a load cell or load pin.
The sensor must have an internal relay that connects a precision resistor across one
leg of the bridge. The LCI-100 uses the Opto 8 output module to energize this relay.

4.1.6 Analog Outputs
The LCI-100 provides two non-isolated analog outputs, or up to four isolated analog
outputs using signal conditioning modules. In both cases these outputs can be 4-20
mA, 0-5 Vdc, or 0-10 Vdc. Each different output type requires a specific hardware
jumper setting on the interface PCB (see Appendix B). Below are wiring diagrams
for the different output types.

Figure 4.17 –Non-isolated Analog Output Hookup
The 4-20 mA non-isolated analog outputs have the ability to be driven by either an
internal 15 Vdc power source or by an external power source (nominally 24 Vdc).
Units are factory configured for internal power. Below are the wiring diagrams for
the external option.

4.1.7 Serial Communications
The LCI-100 provides both RS-232 and RS-485 serial communication options with a
maximum of two ports. The base model has no serial ports. A RS-232 network port
can be added for data logging to a single remote device in close proximity. For long
cable runs or multi-drop applications, this option can be replaced by an electrically-
isolated RS-485 port. An auxiliary RS-232 port is also available for serial output to
user-supplied logging or display devices.
The RS-485 serial termination is set using the hardware jumper settings on the inter-
face PCB as shown in Appendix B.
The RS-232 network and auxiliary ports are accessed via 10-pin ribbon cable con-
nectors on the side of the unit. Cable pinouts are supplied with these options. The
wiring diagram for the RS-485 network port is shown below.
