Product Overview: The 4S-41 Selector Control Board (PCBNAV-01) by Advanced Microcontrols is a position-sensing control board designed for multi-floor elevator systems. It uses photosensors to detect reflective tape markers in the elevator shaft, triggering sequential floor outputs (FZ1, FZ2, FZ3, etc.) to indicate car position. The board operates on 12-20VDC and incorporates PIC microcontroller logic, Schmitt trigger ICs, power transistors for output switching, and onboard LEDs for status indication. Commonly found in residential and light-duty commercial elevator installations, it processes sensor inputs to coordinate floor selection and positioning control.
Category: Control Board
Manufacturer: Advanced Microcontrols, Inc.
Manufacturer Part Number: PCBNAV-01
Also Known As(AKA): ASYNAV-01
Common Failures
Common issues with the selector control board include failure to power on specific outputs, often due to external factors such as dirty reflective tape affecting photo transistors. Defective components, like missing or shorted transistors, and contamination of photo transistors have also been identified as causes of malfunction. Additionally, damaged or leaking capacitors and shorted transistors have been noted as contributing factors.
Repair Approach
Repairs typically involve cleaning contaminants from photo sensors and the board, as well as replacing defective components such as transistors and capacitors. Diagnostic testing is performed to identify faulty parts and verify component function. Necessary components are replaced, missing components are reinstalled, and solder connections are cleaned up to restore functionality.
Testing & Quality
After repairs, units undergo thorough testing, including burn-in tests with load, to verify that identified issues have been addressed. Functional tests are conducted to confirm that the control board operates correctly across all outputs.
