Common faults
What usually fails on a unit like the FLXA21
Analytical and laboratory instruments are complex, but the faults that stop them are often in a single board, power supply, pump or detector module. Repairing that module keeps the instrument and its validated methods in service.
Board and power supply failures
Failed power supplies, control boards and interface boards stop the instrument or its software connection.
Detector faults
Lamp, detector board or signal chain faults that cause noise, drift or loss of signal.
Pump and fluidics faults
Pump drive boards, valves and sensors on chromatography and dosing systems.
Communication loss
The instrument stops talking to its controlling PC or software.
Temperature control faults
Oven, column and sample-chamber heaters and their controllers.
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
- Record error messages and log files from the software.
- Check consumables such as lamps, seals and filters first.
- Note which module the software reports as faulty.
Leave to a specialist
- Board-level repair of instrument modules.
- Performance checks after repair.
