Overview

The Optima OP-900 Series Indicator is a digital weight indicator designed for various weighing applications, available in LED (OP-900A) and LCD (OP-900B) versions. This user's manual provides comprehensive instructions for its operation, calibration, and maintenance.

Function Description:

The OP-900 series indicator serves as the central display and control unit for weighing scales. It processes signals from load cells to display weight readings, perform various weighing functions, and interface with external devices. Its primary functions include:

  • Weight Display: Shows gross, net, and tare weights in multiple units (kg, lb, g, oz, lb:oz).
  • Counting Function: Allows for counting a large volume of identical parts by setting a sample weight.
  • Accumulation Function: Adds multiple weights and totals them together, capable of accumulating up to 999 different weights.
  • Hold Functions: Offers four different hold options:
    • Peak Hold: Captures and displays the highest weight recorded (useful for materials testing).
    • Manual Hold: Grabs and holds the current weight until released.
    • Auto Hold: Automatically holds stable weight data for 3 seconds when above 20 divisions.
    • Average Hold: Calculates and displays the average weight sampled over 3 seconds (ideal for animal weighing).
  • Zeroing: Resets the scale to zero when empty or to compensate for material build-up.
  • Tare Function: Allows for taring out container weights to display only the net product weight. It also supports pre-set tare weights.
  • Alarm Functions: Features upper and lower limit alarms, indicated by flashing "OVER," "ACCEPT," or "UNDER" lights.
  • Connectivity: Supports RS232 serial output for connecting to PCs, printers, or remote displays. Optional 4-20mA analog output and relay output are also available.

  • Parameter Settings: Extensive configurable parameters (C01 to C45) for fine-tuning indicator behavior, including decimal settings, graduation, maximum capacity, zero tracking, standstill time, digital and noise filters, and communication settings.
  • Serial Output Formats:
    • Continuous Sending Mode (C18=1): For remote displays/scoreboards.
    • Print Mode (C18=2): For non-adhesive ticket printers, with configurable date, time, and print content.
    • Command Request Mode (C18=3): Allows a computer to send ASCII commands (T, Z, P, R, C, G) to request specific data or actions from the indicator.
    • Computer Continuous Sending Mode (C18=4): Streams weight data continuously to a computer.
    • PC or Remote Display Continuous Sending Mode (C18=5): Combines features for both PC and remote display continuous data streaming.
    • Print to Adhesive Label Printers (C18=5 & C18=6): Supports printing to Optima and Zebra label printers with specific formats for date, time, net, tare, and gross weights.
  • DB9 Connection: A 9-pin serial connector for RS232, 4-20mA analog output, and relay output, depending on the indicator model and options.
  • Load Cell Connection: Supports 4-wire or 6-wire load cell connections, up to 6 load cells of 350Ω, via quick disconnect or inner terminal block.

Maintenance Features:

  • Calibration Procedure: Detailed steps for both single-point and linear (multiple weight) calibration, allowing for precise adjustment of the scale. This involves setting units, decimal places, graduation, maximum capacity, zero calibration, and span calibration.
  • Troubleshooting Guide: Provides solutions for common error codes such as overload, wrong load cell connection, calibration issues, negative input signals, unstable calibration signals, EEPROM errors, and exceed zero range.
  • Battery Management: Recommendations for fully discharging and recharging the optional internal battery monthly to maintain its condition and removing it for long-term storage to prevent leakage.
  • Anti-Static Prevention: Emphasizes the importance of discharging static electricity from the operator's body before opening the indicator to prevent damage to ESDS devices.
  • Professional Maintenance: Calibration inspection and maintenance are restricted to non-professional staff to ensure safety and accuracy.

The Optima OP-900 Series Indicator is a versatile and robust weighing solution, suitable for a wide range of industrial and commercial applications requiring accurate weight measurement and data management.
