Spotline V2: Troubleshooting

Machines are complex - making them run smoothly can be challenging. Below are common issues and how to solve them.

• Motor won't move and immediately trips a VFD fault

  • Load the correct parameters and run an autotune

• Motion isn't smooth

  • check Spikemark PID values

  • reduce load and check motion

  • check rigging for hang-ups

• X-Groove sensor is tripping

  • Check for x-groove

  • Check for cable "knuckle" at drum entry location

  • Adjust the x-groove sensor

    • Each sensor has a light that turns on when the bar is WITHIN PROXIMITY. If either light is out, you will see an XG.

• Positioning is poor

  • Separate motor and signal cables

• Load cells

  • Check load cell scaling

  • adjust minimum/maximum loads

  • check for interference/hangups

Manually releasing both brakes will release whatever weight is hanging from the Spotline. Keep in mind, the heavier the load hanging, the quicker it will come in when the brakes are released. The minimum release weight is 45lbs.

• Manual Brake Release

  • The Spotline has two brakes: Motor Brake & Load Brake. Each brake can be individually released from the Stagehand. Each brake can also be manually released from the machine

  • Release the Motor Brake

    • insert the manual brake release handle (attached to the motor) into the brake at the top of the motor.

    • Push and hold the handle UP to release the motor brake

  • Release the Load Brake

    • insert the manual brake release handle (attached to the Spotline frame) into the brake.

    • Push and hold the brake handle AWAY from the machine to release the load brake.
