Issue:

The sliding window demand modules in the ION Revenue Test Framework cannot be reset with a push-button. The “Demand Reset” button resets the values but does not reset the period, causing testing delays.

Environment:

• ION8600 meters configured with the ION Revenue Test Framework
• Sliding Window Demand modules used for demand testing
• PME/ION Designer for configuration and testing

Cause:

The sliding window demand modules are synchronized with the meter’s system clock and only reset at fixed intervals (e.g., 00, 15, 30, 45 minutes for a 15-minute period). This design prevents manual reset of the demand period, limiting flexibility during testing.

Resolution:

Workaround: Modify the ION Revenue Test Framework as follows:

1- Add a Pulse Merge module:

• • Connect Pulse In 1 to Test Dmd Rset of the Test Dmd Rset module.
  • Connect Pulse In 2 to CNV1 On Pulse output of the Test Mode Rset module.

2- Add a One-Shot Timer module:

• • Link its Sync input to the Pulse Out of the Pulse Merge module.

3- Connect the Trigger output of the One-Shot Timer to the Sync input of both KW sd del T and KW sd rec T modules.
