TROUBLESHOOTING
This section consists of some common MAWS problems, their probable
causes, and remedies.
Basic Procedure for Troubleshooting
When troubleshooting the MAWS system, write a problem report
consisting the following issues:
- What failed (what worked / did not work)?
- Where did it fail (location and environment)?
- When did it fail (date, immediately / after a while / periodically /
randomly)?
- How many failed (only one defect / other same or similar defects /
several failures in one unit)?
- What was connected to the product and to which connectors?
- Input power source type, voltage and list of other items (lighting,
heaters, motors etc.) that were connected to the same power output.
- What was done when the failure was noticed?
