Expansion Unit Connection
This section explains how to install this product on a DIN rail and how to connect
this product to an expansion unit.
Up to 8 expansion units can be connected to 1 instance of this product. However,
each dual output type will be treated as 2 expansion units.
Turn off the power supply before connecting this product to an
expansion unit.
1 Align the claw at the bottom of this product with the DIN rail. While pushing this
product in the direction of arrow 1, push down in the direction of arrow 2.

Reference
Usage example:
When units are connected as shown in the following figure, the
corresponding wire colors are assigned as shown in the table below.
The LV-N12 is a dual output type, so it is treated as 2 expansion units.

Write settings to the
connected expansion
units.
LOCK indicator/button
This is both an indicator
and a button.
It lights (in orange) when
the operation of the buttons
are disabled.
MEMORY indicators
The indicator whose
memory number matches
the expansion units model
configuration and settings
will be lit (in orange). While
a memory number is

Error status
Saving settings [SAVE]
Up to three sets of settings for the expansion units connected to this product
can be saved.
1 Press the SELECT button to select the memory number in which to save the
settings.
(Each time the SELECT button is pressed, the memory number that is blinking changes.)
2 With the desired MEMORY indicator blinking, hold down the SAVE button
for 3 seconds or more.
Writing settings [LOAD]
Write the saved settings on this product to the connected expansion units.
1 Press the SELECT button to select the memory number in which the set-
tings to write have been inserted.
(Each time the SELECT button is pressed, the memory number that is blinking changes.)
2 With the desired MEMORY indicator blinking, hold down the LOAD button
for 3 seconds or more.
* An error will occur if the settings to write do not match the number of
expansion units, the expansion unit models, and/or the position in which
the expansion units are connected. (See page 3.)
Preventing incorrect operations (batch key lock) [LOCK]
Disable button operations not only on this product but also on all expansion
units that are connected to this product.
1 Hold down the LOCK button for 3 seconds or more. Cancel: Use the same
procedure.
Common input
A common external input signal can be sent to the expansion units that
support external input by controlling the common input (pink wire) of this
product.
* For details on the expansion units that support the common input, see
page 3.
* If the external input for an expansion unit is in already in the ON state, the
common external input will be ignored by that unit.
Common output
When an error occurs on this product or on an expansion unit connected to
this product, the common output (red wire) turns ON. If the "Limit Detection" or
“Limit Setting Output Mode” of an expansion unit is being used, the alarm
output of each function will be linked to the common output (red wire).
Setting initialization
Initialize all the settings and return this product to its factory default state.
1 Hold down the SAVE button, LOAD button, and LOCK button for 3 seconds
or more.
The connected expansion units are not initialized.
Save lock function
This function prevents incorrect operations of the SAVE button and only the
SAVE button.
By using the LOCK button at the same time that the settings are saved, it can
be ensured that it is not easy to overwrite the settings.
1 Press the SELECT button to select the memory number in which to save the
settings.
(Each time the SELECT button is pressed, the memory number that is
blinking changes.)
2 With the desired MEMORY indicator blinking, hold down the LOCK button
and the SAVE button for 3 seconds or more.
To overwrite the settings, perform the save lock function operation again.
(The settings cannot be saved by just pressing the SAVE button.)
To cancel the save lock function, initialize the settings.
(By initializing the settings, this product will return to its factory default state.)
By connecting expansion units to this product, it is possible to send independent
control output information from each expansion unit through this device.
The control outputs are assigned to the wire colors in the following table in the
order in which the expansion units are connected next to this product.
