    While other response times can be provided, field modification is not recommended since damage might result that could void the product warranty. Contact Dynalco if you need a different relay response time. Adjusting Individual Set Points Verify that the SST-2000A/H is calibrated to the correct full-scale frequency range (see page 22).
  • Page 29 Calibrating the Speed Switch Apply the calculated set point frequency to terminals 5 (HI) & 6 (COM). Apply operating power to the SST-2000A/H. See lid of your SST-2000A/H or spec sheet for power choices. Select the appropriate set point trim pot. Turn the pot: Counterclockwise to lower the set point value (reduce the speed at which the set point relay will trip ).
