Product Overview: The Kelley TS-402/501 is a control module designed for loading dock equipment operation. It processes multiple input signals through opto-isolated circuits and drives both lighting outputs via N-channel MOSFETs and DC motor outputs through automotive relays. The module operates on 12VAC input with an internal 8VDC regulator for logic circuits, which are based on 4000 series CMOS chips and dual 556 timers. It features a 14-position connector interface with indicator LEDs for input and output status monitoring, and requires an external 12VDC supply for common output power.

Common Failures
The TS-402/501 Control Module may experience issues with output activation due to connection problems. Issues that have been observed include failed connections at the common pin on the output connector, LED polarity concerns, and relay connection faults. These items are evaluated and addressed during the repair process as needed.
Repair Approach
Repairs may involve resoldering connections, particularly at the common terminal, to restore proper functionality. Damaged traces are repaired where applicable, and defective components such as LEDs, switches, and electrolytic capacitors are replaced as necessary. In some cases, the control module may be re-potted in a new case to protect internal components.
Testing & Quality
Diagnostic testing is performed to verify repair integrity. This includes confirming that inputs and outputs can be activated correctly, inspecting relays for proper activation with a 12V supply, and testing indicators to ensure they function as intended. Final testing is conducted to confirm that the module meets expected performance standards.
