Operation Notes
When using the DVR-3901 module, observe the following operation
notes:
•
If you change parameters within 16 seconds after the
NEO VR banner first appears on the VFD, your changes will not be
saved. Parameter changes that you make after this 16-second delay
will be saved and restored if the module loses power and must be
restarted.
• Although your parameter changes seem to take effect immediately,
the settings are only saved after 20 seconds of inactivity.
• When you set the RstSetting (Restore Settings) parameter to Yes ,
the module takes several seconds to reset all of the parameters.
(
Setup parameters are not affected by this restore setting mode.)
See “Operator and All List Parameters” on page 30 for a list of the
default settings that you activate when setting RstSetting to
Yes
.
• Changes in some parameters will cause additional changes in other
parameters, or lock them out entirely. See
“Functions and Controls”
on page 57 for more information on these cross-functional
parameter changes.
State Recovery Parameter Availability
The parameter settings for this module are automatically saved onto the
3901RES-E resource module installed in your NEO frame every five
minutes. If a module should fail and be replaced with a cold spare, the
state parameters can be automatically recovered. For more information
on this feature, see the
NEO FR-3901, FR-3903, and FR-3923
Mounting Frames Installation and Operation Manual (Edition E and
above).
Caution
Failure to observe these
Operation Notes will result in
accidental changes to the
module’s parameter settings.
