    What to do if the 'Power Out' LED on my Digitroll SEED MASTER Plus monitor doesn't light up or blinks?
    • R
      Ronald FerrellAug 10, 2025
      If the 'Power Out' LED on your Digitroll Control Systems monitor is not lighting up or is blinking, it could be due to an external short circuit, a cable pinch, or a defective seed module. First, disconnect the modules from the monitor. If that doesn't work, systematically disconnect the modules starting from the monitor side. If the LED lights up, reconnect and disconnect the next connector until you find the short circuit area. This disconnection process can also help you identify a defective unit causing the short circuit.

    Why are sensor signals partially or totally missing on my Digitroll SEED MASTER Plus Control Systems monitor even though the 'Power Out' light is on?
    • H
      Hayley EverettNov 25, 2025
      If your Digitroll Control Systems monitor shows the 'Power Out' light but sensor signals are partially or totally missing, it could be due to several reasons. It may be caused by accidentally switching off row detection, so double-check and reset it if needed. Also, a damaged cable or connector, or a defective module could be the cause. You can push the TEST button and note the number of the last detected seed module to help identify the issue. Another possibility is damaged battery leads. To find a defect in a linear system, try disconnecting and bridging the suspected defective module. Finally, the output side of module 4 or module 5 could be defective; push TEST to verify and replace the defective module if necessary. Damaged communication cables or connectors between modules 4 and 5 co...

Overview

  4. Maintenance Features

The DIGITROLL SEED MASTER Plus is a seeding control system designed for planters with 1-16 rows, featuring an area counter and various monitoring and control functionalities.

Function Description

The SEED MASTER Plus system provides comprehensive control and monitoring of seeding operations. Its primary functions include:

  • Seeding Control: Monitors seeding continuity on all rows simultaneously, detects missing seed drops, and provides alarms. It supports individual seed spacing adjustments for each row and offers a seeding blockage control mode.
  • Population Ratio Control: Displays the ratio of desired to actual measured population in each row using bar graphs, suitable for seeds larger than 5 mm (e.g., maize, sunflower, sugar beet).
  • Hectare Counting: Measures and stores total and partial seeded areas up to 999.99 hectares and distance traveled up to 65,000 meters. Counting starts/stops based on seed sensor signals or continuously if sensors are not applied.
  • System Test: Performs sensor diagnostics, automatic recognition, and readiness tests of seed sensors, and displays dusty or blocked sensors.
  • Data Storage: Nonvolatile memory ensures safe storage of measured and adjusted data.

Important Technical Specifications

  • Monitor: Illuminated LCD display, massive aluminum housing, audible and visual alarms with adjustable horn volume, 8 selectable languages.
  • System Construction: Infrared sensation, linear string system connectivity for up to 16 rows, exchangeable modules with automatic sequence determination, harness-free network for easy cabling and mounting.
  • Seed Sensors:
    • DS 1000: Custom-designed for seeder type, placed in the seed tube.
    • DS 2000: Custom-designed for seeder type, placed in the coulter.
  • Speed Sensor: DA 02 speed sensor module (DSI-18 speed sensor). Inductive sensor detecting iron parts (e.g., bolt heads) on a non-slipping wheel. Optimal sensing distance is 4-6 mm from the bolt head. Provides at least one signal for every 30-60 cm traveled, not exceeding 100 cm per signal.
  • Power Supply: 12 VDC (min. 8.5V), connected after a fuse (max. 3A).
  • Measurement Ranges:
    • Seeded area: up to 999.99 hectares.
    • Distance: up to 65,000 meters.
    • Seed spacing adjustment: 3.0 - 45.0 cm.
    • Shortfall alarm length: 0.5 - 20 seconds.
    • Working width: 0.75 - 30 meters.
    • Seeded grains: up to 1 billion seeds.

Usage Features

  • Monitor Placement: Mount in a clearly visible location in the tractor cabin, using the U-bracket and bolts. Position to avoid direct sunlight on the LCD. The illuminated display ensures visibility at night.
  • Switch On: Upon power-up, the console displays the running software version, selected horn volume, seed spacing values, and offers instant setting options, followed by a system test.
  • Basic Data Settings:
    • Optimal Seed Spacing: Two options: "Normal" for a single spacing value, or "Hybrid" for individual spacing values per row.
    • Shortfall Alarm Length: Adjustable between 0.5 and 20 seconds.
    • Population Control Limits: Set minimum and maximum limits for population, triggering alarms if values go beyond these ranges. Audible alarms can be disabled.
    • Seed Size and Shape: For DS 2000 sensors, input seed characteristics (3-5 mm / 6-9 mm, round / long) for precise detection. Changes trigger a system test.
    • Row Skip: Temporarily disable control for unused rows to prevent continuous alarms.
    • Working Width: Enter the seeding machine's working width (0.75-30 meters) for accurate area calculation.
    • 100 Speed Signal Count: Calibrate the speed sensor by measuring the distance traveled over 100 speed signals. A warning beep sounds at the 90th signal to slow down.
  • Seeding Control Modes:
    • Blockage Control: Detects missing seed drops; if a seed is missing for longer than a preset limit (0.25-2.00 seconds, adjustable in 6 steps), the seed symbol disappears, and an alarm sounds. Alarm is disabled during turns at landmarks. A "display hold" function allows freezing the display to analyze the seeding situation when the machine is stopped.
    • Population Ratio Control: Displays desired vs. actual population using bar graphs, calculated over approximately 40 meters. Alarms sound if the difference exceeds set limits.
  • Stored Seeding Data: Access total and partial seeded area, total seeded grains, and average seed/hectare. Data can be reset (total or partial).
  • Distance Measurement: Measures distance traveled based on 100 speed signal data. Measurement starts/stops with button presses.

Maintenance Features

  • Cables and Connectors: Keep them unhurt and check regularly.
  • Sensors: Clean at the end of each seeding season. Close the end of extension cables with waterproof seals.
  • Monitor Protection:
    • Do not expose to direct water.
    • Store between -20°C and +40°C.
    • Protect from excessive heat and dust.
    • Remove from the cabin for winter storage and keep in a dry, vapor-free place.
    • Protect the front, display, and buttons from strong mechanical impacts.
    • Clean with a slightly wet wipe.
  • Internal Components: No battery or other parts requiring maintenance.
  • Troubleshooting:
    • No lights on display: Check 12VDC power supply, polarity, ON button, and main switch/electronic part. An auto-reset fuse is built-in.
    • "POWER OUT" LED not lighting or blinking: Indicates power supply status. Blinking suggests partial overload, off suggests total external short circuit. Disconnect modules systematically to identify cable pinch-in or defected seed modules.
    • Missing sensor signals: Check for mistaken row detection switch-off, hurt cables/connectors, or defected modules. Systematically disconnect and bridge modules to pinpoint the issue.
    • Blockage indicated after cleaning: Insert a stick into the seed sensor; if the LED gets dark, it works; otherwise, the sensor is defected.
    • Irregular seed drops when seeder stopped: Sensitivity may be too high; adjust the time limit.
    • No seed detection with working seeder: Adjust for small seeds or increase missing seed time interval. Check for defected modules by inserting a stick.
