Common faults
What usually fails on a unit like the BCU 460-5/1LW3GB
Control, interface and processor boards inside printing presses, chillers, compressors and special-purpose machines are often unavailable or very expensive as spares. Board-level repair finds the failed components and returns the original board.
On-board power faults
Failed regulators, DC-DC converters and capacitors stop the board or cause random resets.
Damaged inputs and outputs
Driver transistors, opto-couplers and relays damaged by shorts or surges in machine wiring.
Processor and memory faults
Failed processors, memory or corrupted firmware stop the board working.
Connector and track damage
Corrosion, burnt tracks and cracked solder joints, often from heat, vibration or moisture.
Communication faults
Failed serial, CAN or network interfaces between boards.
First checks
What to check before calling an engineer
Isolate and lock out the supply, and wait for stored energy to discharge, before opening anything.
Safe for plant staff
- Photograph connectors, jumpers and switches before removing the board.
- Note error messages from the machine.
- Check the supply voltages reaching the board.
Leave to a specialist
