Free Source
This button selects a phantom device that can be used to release or “free” devices on the
data (control) level. A free source can also be used with tielines to free the tieline for others
to use.
Use it as if it were a source.
(The actual free source is configured in the Level Set Details page of NV9000-SE Utilities.)
Hold
The ‘Hold’ button is a toggle. Press it once to activate “hold” mode, press it again to
deactivate “hold.” The button is high-tally when hold mode is active and low-tally when it is
not.
You can activate or deactivate hold mode at any time during an MD selection or a
breakaway selection in X-Y mode. Your selection remains intact and the panel subsequently
operates in hold mode or non-hold mode according to the hold button state.
MD Mode
In MD mode, turning hold mode on allows you to select more than one destination button
at a time. When you select a source, the source applies to all selected (high-tally)
destinations. If hold is still on when you press ‘Take’, the selected destinations remain
selected and the display reflects the selected destinations. The buttons for the selected
destinations remain high-tally.
Without hold enabled, the panel has no destinations selected after an MD take and the
buttons for the selected destinations go low-tally.
When hold is active, all selected MD destinations get the source you selected most recently
(in case you change your mind and selected another source).
X-Y Mode
In X-Y mode, the hold button causes breakaway levels to be retained after a take. The levels
you selected (and deselected) remain selected (or unselected) as they were before the take.
Information
The ‘Information’ button causes the panel to present auxiliary information on the
alphanumeric display. Such information might be level-mapped sources.
