Caution in Installation and Operation of Digital Speed Controller

Digital speed controller (hereinafter described as “DS”) is assumed to be operated in set-up change (1) at startup of equipment and (2) during equipment run, and work is assumed to be done in a safety fence. Touching partly to the moving parts or carrier parts may cause an injury to an operator.
Follow the caution notes below when you operate DS.
  1. Grasp the operation range of the moving parts and carrier parts so you may not touch partly to them. Make sure to have only the operators who have got safety education to operate the equipment.
  2. If a wired or wireless teaching pendant or PC is connected, there should be “Tool Connected” displayed in the DS display window and operation on DS gets unavailable.
    When you check the display, make sure to grasp the operation range and get away from the range far enough so you may not touch partly to the moving parts or carrier parts.
  3. Separate the DS operation part from any moving part or carrier part, install an area sensor such as the light curtain so you would not get caught on finger or hand.
  4. DS is set in low speed at 250mm/s or less at delivery for safety. In case you set the speed above 250mm/s, increase the setting speed step by step to consider safe operation.
  5. Have two or more operators for operation to secure an operator to watch the work in addition to an operator to operate DS.
    Build up an appropriate safety circuit and equip it with an emergency stop button and an enable switch with three positions. The watcher should stop the equipment immediately in case of any emergency to ensure safety of the DS operator.
  6. Build up the safety circuit that does not start up only with power supply or restoration from power outage.
  7. Install the actuator with DS considering a position easy to operate or see the DS to secure your body position or posture while operating DS. Failure to do so could hurt your back, neck or wrist.
  8. Check that there is no abnormality on the safety circuit or DS itself before you start operating on the DS. Have an appropriate measure when any abnormality is found before start operation.
  9. Create a “Operation Standard” necessary to secure safety, educate an operator based on this standard, and have only operators who is well educated with the standard (operators who received safety education).
  10. When it is a work in a safety fence, make sure to put up a sign showing “Work on-going in Safety Fence” at a place where the sign can be seen from outside the fence before starting the work.
  11. Make sure to secure safety and wear a helmet, safety gloves and safety goggles as necessary.
  12. Have a risk assessment conducted so any risks that could be considered get reduced and removed to the acceptable level.
The notes above are the caution notes for installation and operation of DS, but they are also general caution for any case other than use of DS, thus some descriptions could duplicate with “Safety Precautions for Our Products”.
