HNT PCM Daily Sampling Procedure

 

To understand the changeover to daily sampling at the Hinton site we must first understand the Normal 6-day sampling period.  Below is a Normal 6-day cycle for filter sampling at Hinton.

 

                Day1:  Install new FPs, System is idle.

                Day2:  Position 1 sample is running

                Day3:  Position 2 sample is running

                Day4:  System is idle

                Day5:  Position 3 sample is running

                Day6:  Position 4 sample is running

 

Changeover to Daily Sampling is a minor change to the site operator.  The installation of one extra filter on Day4 of sampling is the only change to site operator activities.  Below is a Daily 6-day cycle for filter sampling at Hinton.

 

                Day1:  Install new FPs, System is idle

                Day2:  Position 1 sample is running

                Day3:  Position 2 sample is running

                Day4:  Install a new FP on Position 1, Position 3 sample is running

                Day5:  Position 4 sample is running

                Day6:  Position 1 sample is running

 

The only difference between Normal sampling and Daily sampling is the last 3 days of the 6-day cycle.  To change to daily sampling a couple of programming changes have to be made.   The changes are to the Configuration Database or to the Process Control.  The move to daily sampling is done by changing the relay and MFC information for PCMDAY4, PCMDAY5 and PCMDAY6.  We will be using the Configuration Database to make these changes.  Within the database there are two tables that have to be changed.  The “calFlows” and “calRelays” tables will change names.  At the Hinton site there are two tables created for each group.  One group of tables is labeled “calFlows” and “calFlowsDaily”.  The second group of tables is labeled “calRelays” and “calRelaysDaily”.  The following are steps to change from Normal to Daily sampling and then from Daily to Normal sampling.

 

Changeover to Daily Sampling

Note:  Programming from Normal sampling to Daily sampling can be made on DAY1, DAY2 or DAY3 of the 6-day cycle.

  1. Shutdown the SiteManager program.
  2. Open the Configuration Database.
  3. Rename the “calFlows” table to “calFlowsStandard”
  4. Rename the “calFlowsDaily” table to “calFlows”
  5. Rename the “calRelays” table to “calRelaysStandard”
  6. Rename the “calRelaysDaily” table to “calRelays”
  7. Restart the SiteManager program.
  8. If the program opens with no issues then all of the programming is complete.  If it doesn’t check to make sure there are no spaces or extra letters on “calFlows” or “calRelays”.

 

Changeover to Normal Sampling

Note:  Programming from Daily sampling to Normal sampling can be made on DAY1, DAY2 or DAY3 of the 6-day cycle.

  1. Shutdown the SiteManager program.
  2. Open the Configuration Database.
  3. Rename the “calFlows” table to “calFlowsDaily”
  4. Rename the “calFlowsStandard” table to “calFlows”
  5. Rename the “calRelays” table to “calRelaysDaily”
  6. Rename the “calRelaysStandard” table to “calRelays”
  7. Restart the SiteManager program.
  8. If the program opens with no issues then all of the programming is complete.  If it doesn’t check to make sure there are no spaces or extra letters on “calFlows” or “calRelays”.
