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.

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
MAIN MENU shown below, then select 2 CALIBRATION; this achieves the same result):

To calibrate the Payout sensor, use the UP and DOWN keys to align the pointer with menu
item 5PAYOUT SCALE, then press ENT to move to the input field. Now use the INCR ,
DECRand keys to change the value to the correct number of pulses per foot. (See §5.9
for details; the number of decimal places shown is adjusted to maintain four-digit accuracy.)
Pressing ENT will accept the new value, pressing ESC will restore the old value. Pressing
RUN saves the displayed value for future use and returns the instrument to RUN mode.

To calibrate the Tension sensor, select menu item 1 TENSION (THREE METHODS) to
move to the 2.1 TENSION CAL METHOD 1 menu shown below. Select Item 2 and enter
the full-scale Tension sensor output in pounds. Then select Item 3 and enter the Tension
offset in pounds. The ENTkey accepts the new value; the ESC key restores the old value.
Press RUN to save the new values for future use and to return to the RUN Screen display.
This completes the initial calibration of the instrument.
