Common Failures
Units received for evaluation have shown issues with the slidewire actuator where the wiper becomes unresponsive after reaching a specific resistance level. Additionally, dead spots along the slidewire's travel path and misalignment of cams have been observed, leading to improper engagement with limit switches. These issues can affect the actuator's performance and reliability.
Repair Approach
Repairs typically involve addressing defective slidewire components to restore normal functionality. For cases with misaligned cams, adjustments are made to ensure proper interaction with the limit switches. If the actuator was initially set up incorrectly, wiring is corrected according to standard manufacturer guidelines.
Testing & Quality
Following repair, each unit is subjected to testing. Actuators are run continuously in both clockwise and counterclockwise directions to evaluate performance across full rotational capacity. This process verifies that repairs have been completed and the devices are performing as expected.
