Common Failures
Common issues reported for this product include failure to update, delayed start-up, driving problems, and malfunctioning pulse inputs. Some units exhibit problems where they need to be turned on for extended periods before functioning properly.

Repair Approach
Repairs may involve cleaning corrosion from board connectors and replacing defective components such as optocouplers. For issues not replicable during diagnostic testing, maintenance procedures may include checking capacitors, diodes, and MOSFETs, and resoldering connections where necessary. Preventive measures may also include testing and replacing weak opto supplies to support reliable operation.
