Explanation of Functions
Memory End Output
If little free space remains in the internal memory or external medium and the following
conditions apply, a single relay output signal is output. This relay signal is energized.
The operation cannot be changed.
For Models with an External Storage Drive
• For both manual save and auto save
•When saving displayed data
When the remaining time
*
for saving the displayed data to the internal memory is
less than a specified time (the memory alarm time), the relay is energized. The
memory alarm time can be set from [1] to [100] hours or [Off].
• When saving event data
When in the mode in which data is always saved to the internal memory (Free
mode), and the remaining time
*
for saving the event data is less than the specified
time (the memory alarm time), the relay is energized.
When in a mode in which data starts being written to the internal memory upon an
event such as an activation of an alarm (Trigger or Rotate mode), the relay is not
energized (and memory end is not output).
* The area of data saved on the external storage medium is considered to be available
space.
• To release this condition, save unsaved data to the storage medium. For the
operating procedure, see section 7.3.
• For auto save only
• The relay becomes energized when the remaining space on the external medium
falls to 10% or less. In this case, the external storage medium icon in the status
display section turns from green to red. However, this does not occur if FIFO is
specified for the CF memory card. When the FIFO method is specified for the
compact flash memory card, the relay is energized if a storage medium error is
detected.
• To release this condition, replace the storage medium.
See section 1.5, " Data Storage Function " for information on auto save and manual save
modes.

For Models with No External Storage Drive
When the memory alarm time is set to something other than OFF (the default setting),
the relay operates in the same manner as described in “For Both Manual Save and
Auto Save” under “For models with an external storage drive.” Also, to deenergize the
relay, clear the internal memory.
See section 7.8 for the operating procedure to clear the internal memory.
