Figure 4-3. Function Keys

Immediate Action Keys

Immediate action keys immediately execute their corresponding function when pressed. Other function keys have commands underneath them that are accessed when the key is pressed.

Output On/Off

This key toggles the output of the ac source between the on and off states. It immediately executes its function as soon as you press it. When off, the ac source output is disabled and the Dis annunciator is on.

Phase Select

This key only applies to three-phase ac sources. It selects the phase to which function commands will be sent, as well as the phase that will be monitored by the Meter and Harmonic functions. At power-on, all phases are selected or coupled, indicating that commands will be sent to all phases. The presently selected phase is indicated by a phase annunciator. Pressing Phase Select immediately selects a different phase. Phase selection is circular; you can return to the starting position by continuously pressing Phase Select.

Shift Trigger

Annunciator On	Phase Selected
φ1, φ2, φ3	All phases selected (phases coupled= ALL)1
φ1	Phase #1 selected (phases coupled= NONE)
φ2	Phase #2 selected (phases coupled= NONE)
φ3	Phase #3 selected (phases coupled= NONE)

1Does not apply to Meter or Harmonic functions.

When the Meter and Harmonic functions are active, Phase Select only rotates through 1, 2, and 3. This is because the Meter and Harmonic functions cannot display multiple phase readings simultaneously. Therefore, it is not possible to select all phases with these functions.
