3. Making connections

3-1. Connecting to the SENSOR
connector
A 2-piece type connector is used.
Insert the included sensor connector plug into the SENSOR
connector.
When wiring the sensor connector plug, press the button for
each pin while inserting the wire.
ATTENTION
Do not connect any connector plug other than one included
because doing so could make it unsafe.

Plug
1
Remove 7–8 mm of the covering from the wire
being connected, and twist it so that the tip does
not come apart.
Suitable wiring is 0.14–1.5 mm2 (26–16 AWG).
2
While pressing the buttons attached to each pin,
insert the wires into the holes so that the tips do
not come apart.
3
Pull the wire gently to confirm that it is securely
clamped into the hole.
4
After the wires have been connected, press the
plug into the indicator until the levers on both its
sides lock.

3-2-1. About the remote sense function

Set the remote sense settings before connecting the sensor
(page 33).
By default, this is set to "UNUSED (4-wire)".
The 6-wire format (remote sense format) is a superior con-
nection method that compensates for reduced voltages due
to cable length and voltage changes due to temperature
changes, for example.
In systems installed outdoors and other situations where
temperature changes are expected, as well as in cases when
general precision is desired, for example, we recommend using
the six-wire format for remote sense.
ATTENTION
o When using the 6-wire format (remote sense format),
before connecting a sensor, always set "REMOTE SENSING"
to "USED (6-wire)".
o Use "UNUSED (4-wire)" with 4-wire format.
o Incorrect connections or settings could cause damage to
sensors.
3-2-2. Notes about bridge voltage
(excitation voltage)
As a reference for setting the bridge voltage, consider that the
output from the sensor should be increased, and set the max-
imum voltage in a range that does not exceed the maximum
safe excitation voltage on the sensor test report.
A sensor could be damaged If this is set to a value that exceeds
its maximum safe excitation voltage.
ATTENTION
o If the maximum safe excitation voltage is less than 5 V, set
the bridge voltage to 2.5 V before connecting.
o In TEDS calibration, when TEDS data is read, if the bridge
voltage setting is greater than the maximum safe excitation
voltage recorded in the TEDS memory, the bridge voltage
will be changed to a value that is no more than the maxi-
mum safe excitation voltage.
NOTE
The default value is 2.5 V (page 33).
