    This manual is intended to cover the installation, set-up, and operation of the LCI-100 and the LCI-90R remote display.

  • Page 7: Quick Start

    LCI-100. For a complete technical description please refer to Sections 3.0-6.0. 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.

  • Page 8: Basic Hardware Configuration

    Sections 4.0-6.0. 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.

    5.5”. 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.

    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.

    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.

  • Page 18: Alarm Outputs

    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. Shunt Calibration Connections...

  • Page 19: Analog Outputs

    Page 19 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).

  • Page 20: Serial Communications

    Figure 4.19 – Isolated Analog Output Hookup – 4 Channels 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.

  • Page 21: Wiring Hookup - Lci-90R Remote Display

    A LCI-90R remote can be used to independently display (and optionally echo) all the line variables measured by a LCI-100. The LCI-90R does not support field I/O and thus has a much reduced wiring and configuration specification compared to the LCI-100. This sec- tion describes the wiring and other options associated with the LCI-90R.

  • Page 22: Lci-90R Communication Ports

    4.2.2 LCI-90R communication ports The LCI-90R provides two serial communication ports on TB2, the network and the auxiliary ports. The connection to the LCI-100 is made via the network port, which is factory configured as either RS-232 (standard) or RS-485 (optional). The RS-232 configuration is suitable when the LCI-100 is connected to a single LCI-90R remote within 50 feet.

Each key has a label at the bottom of the screen that identifies its function. When a key is pressed its function (and the label) changes to reflect the current “operating mode”...

  • Page 25: Programming Menu

    Page 25 Programming Menu The LCI-100 is user programmable via the front panel keypad and the display. Program- ming options include selection of input/output signal ranges, setting screen displays and formats, defining alarm points, and calibrating the unit. The menu tree is shown below in Figure 5.2.

  • Page 26: Alarms

    Figure 5.2 – LCI 100 Menu Tree Alarms The LCI-100 provides the user with up to six optional visual alarms that can be configured to indicate high and low conditions of Tension, Payout, and line Speed. Each alarm can be assigned to any of the three measured variables, and can be designated as a high or low alarm.

  • Page 27: Acknowledging Alarms

    This alarm configuration menu is covered in Section 5.3.3. In addition to these six high-level alarms, the LCI-100 can be configured to monitor each analog input channel, watching for a low-level fault condition. This is particularly useful with multiple input configurations, where the failure of a single sensor might not be easily noticed.

    150 FT 5.7.1 Wrap angle adjustments The LCI-100 has the ability to correct for variations in sheave geometry by allowing the user to specify the wrap angle.

  • Page 36: Payout Calibration

    Payout Scale = Number of Targets / Sheave Circumference The LCI-100 expects to receive pulses generated by a pair of offset sensors that see the targets in sequence (or quadruture pulses generated by a shaft encoder). The quadrature signal allows the count to increment or decrement depending on the direction of motion.

  • Page 37: Display Configuration

    5.10 Display Configuration The LCI-100 allows the user to change the display position of the three line variables on the RUN Screen, change the units of measure, and the number of decimal places. The LCI-100 also has a screen saver to prolong the life of the display. These features are accessed via the 3.0 DISPLAY CONFIGURATION menu.

    In this case, the LCI-100 displays “OL” on top of the rightmost digit to indicate that the display is over the digit limit for that field. If this happens, consider switching that variable to a different display location or use a different set of units.

  • Page 40: Hardware Configuration

    Page 40 Hardware Configuration The LCI-100 will work with a wide variety of input sensors, output alarms and data systems. The 4.0 SYSTEM CONFIGURATION menu, shown below, allows the LCI-100 to be customized for a particular installation. Once these settings have been made, this menu also offers a security feature that locks out unauthorized changes.

    LCI-100 are NONE and TENSION; consul the factory for other options. Items 4-7 are disabled when NONE is selected. Item 4 The LCI-100 can combine the input from several sensors. The choices here are NONE, SUM or 2-AXIS. Use of multiple sensors is discussed in Section 6.3.1.

  • Page 46: Local/Remote Operation Modes

    POLLED Item 1 Selects LOCAL, REM-A or REM-B modes of operation. REM-A and REM-B modes turn the LCI-100 into a remote display, receiving data through the network communication port, rather than field sensors. See Section 7.0 for details. Item 2 This item only appears when units are set to LOCAL mode. Selecting this item, changing it to YES, and pressing RUN downloads the entire set of configuration parameters to all REM-B units attached to the Network port.

When a LCI-100 is set as REM-A, it will not accept configuration information from a LOCAL display; it is only configured from the keypad and menu. REM-B displays (also called "Blind Remotes") mimic the operating mode of the LCI-90R, which has no buttons and can only be configured from a LOCAL unit.

  • Page 49: Polling Strings

    "Terminal Emulator" program running on a PC (for example "HyperTerm"), just hitting the Enter key will cause the LCI-100 to send a data string. Similarly, a data- logging system only needs to send a "blank line" to get a response.

    (including the Alarm settings) in a manner that differs from the Local unit. Setting up a REM-A display is completely straight-forward: simply use the Keypad keys as described for the Local LCI-100, but be sure to set Item 1 of the 4.4 SERIAL CONFIGURATION menu to REM-A.

  • Page 51: Blind Remotes - Rem-B

    Blind Remote displays (LCI-90R) have the same display and communications hardware found in the LCI-100, but lack a front panel keypad. This means that they can only be con- figured by connecting them to a LCI-100 Local display, or, per request, by the Supplier.
