Technical Bulletin 001

Affected systems: All TE-Wilbur samplers running V3.50 of the PLC software are affected by this technical update.
Technical Issue: When configuring a 1 in 3, 1 in 6 or 1 in12 day sample schedule, the sample schedule will stop inadvertently at the end of the month due to a technical issue with the PLC software version 3.5. This logic was put into place to cancel the sample if the user would change the date in the future while a sample was programmed to run a scheduled sample. The logic was flawed and will stop the sample if the current day of the month is less than the next scheduled sample date.
Technical Fix: Version 3.51 of the PLC software corrects this issue
