2.3.2 Jumpers

This section describes the jumpers:

  • Free run (J6) enables a free running pulse signal of 1 Hz when installed. The pulse signal triggers circuits necessary for a load transient.
  • Disable zero (J7) disables the zero-level step during a load transient when installed. The load stays at the adjusted low level until the next cycle.
  • Low (J4) and Mid (J5) set ranges of the slew rate adjust. The default setting when both jumpers are open sets the fastest slew rate.
  • Low (J8) and Mid (J9) set ranges of the period adjustments. The default setting when both jumpers are open sets the shortest period.
  • Low (J10) and Mid (J11) set ranges of the delay adjustments. The default setting when both jumpers are open sets the shortest delay.
  • Low (J12) and Mid (J13) set ranges of the pulse width adjustments. The default setting when both jumpers are open sets the shortest pulse width.
