Sensor Adjustment restores reliable, code-compliant safety performance so doors close smoothly and predictably. If the door won’t close or reverses unexpectedly, sensor lights are blinking or inconsistent, safety responses are intermittent, sensors are obstructed by dirt or debris, or you’re forced to hold the wall button to complete a close, alignment and calibration are likely off. We clean and realign photo-eyes, secure mounts and wiring, verify line-of-sight and height, test force and reversal settings, and validate control-board communication. When components are outdated or damaged, we recommend precise replacements to restore full safety functionality. The result: consistent closures, dependable obstruction detection, fewer nuisance reversals, and peace of mind that the system meets safety standards without manual workarounds.
