Optical detectors "BQ" of moving yarns
4. Installation instruction
The sensor is fastened by two pins M4 so that the controlled moving yarn intersects the infra red beam. The connection cable should be fastened not to be subjected to tension and bending to avoid a rapture. The optical elements can be covered with dust during the operation. Thus it is convenient to wipe them with a dry, soft tissue or clean them using alcohol.
The sensor does not need any set up under the operation. Any possible defects are recommended to be sorted out by changing sensors and sending the defective sensors back to producer for repair. In case of any check on the device, consumer looses warranty rights.
