| Causes of Issue | |||||
| Winding 1 set to 8.7 so it should be calculating to 87 amps but instead is ramping to 104. | |||||
| Solution to this Issue | |||||
| The stop value entered in Action Specs is set to 120% of expected pickup, hence 104.4 amps. By reducing this to 103% it should result in allowing the test to ramp to 89.6 amps, close to the limit of the Manta MTS-5000. Another option would be to hookup to a different winding with a lower tap, maybe Winding 2. Then look in the Global Defines and change the formula to calculate based off of WDG_TAP2 rather than WDG_TAP1. | |||||
