Operating Concepts
S, B, X
Destination Protect
This button is a toggle that sets or clears a
protect
on the current destination device. The protect can
be removed at the panel that originally set the protect, at any panel that has the same user ID, or by
a forced release at any panel.
Unless your panel is configured for forced release, you cannot unlock or unprotect a destination
locked or protected by someone else. The display will show “NotOwner” briefly.
You cannot take a source to a protected destination if someone else protected it. The display will
read “Protect” and show the user’s name. However, you
can
take a source to a protected destination
if you protected it or it is protected at another panel that has your user name. Doing so does not
remove the protection.
Locks and protects apply to the default destination in single-destination mode, with or without
breakaway. They apply to the currently selected destination in limited X-Y mode. They are not
available in multi-destination mode.
When you protect a destination, the ‘Destination Protect’ button goes high-tally green. Any ‘Desti-
nation Lock’ button remains unaffected. Note that you cannot protect a locked destination.
S
Protects apply to selected levels in single-destination mode with breakaway.
S
The NV9602 provides no explicit indication, during operation, whether a destination is locked
or unlocked.
X
Destination Shift
The ‘Destination Shift’ button toggles between the first and second destination sets (which are
available only in limited X-Y mode).
When you press a ‘Destination’ button, it will select the destination from the chosen sets.
The names of destination devices appear in the ‘Destination’ display.
S, B, X
Free Source
The button selects a pre-defined phantom device that can be used to release or “free” devices on the
data (machine control) level. A free source can also be used with tielines to free the tieline for oth-
ers to use. The actual free source used is defined in the NV9000 configuration.
Use this button as if it were a source button.
B, X
Hold
The button is a toggle; press it once to place the panel in “hold mode.” Press it again to cancel “hold
mode.” (The panel might or might not be configured to power up in hold mode.)
In single-destination mode with breakaway, this button retains breakaway levels after a take.
In limited X-Y mode, this button allows you to perform a gang (or “dub”) switch. In hold mode,
destination selections are cumulative, and not mutually exclusive. See
on page 28.
The ‘Destination’ field of the display shows the most recently selected destination under hold
mode.
The button definition has no fields to configure.
