reach volume described
in specifications.
●ZERO-adjust and/or SPAN-
adjust not possible.
●Power line is unplugged, or power supply
terminal plug is defective.
●Sensor cord is of inappropriate length.
●Sensor wire is laid too close to other wires. ●Lay sensor wire separately from other wires.
●Controller is not compatible with sensor
other than that specified.

●Volume of subject to be sensed is less than the
standard.
●Sensor is different from that specified.
●See reference data.
●The guarantee of the product is the one to mean the
guarantee of this machine unit.
●We will make the term of a guarantee of a product

●When failure arises by a manufacturer's responsibi-
lity during the above-mentioned term of a guarantee,
repair of the failure portion of a product or compo-
nent replacement is performed.
However, when it corresponds to below, We will carry
out the outside of the scope of a guarantee.
①When based on unsuitable condition, environment,
handing, and use of those other than the contents
checked by the specification value of a product,
the specifications exchaged separetely, etc.
②When the cause of failure is based on reasons other
than supplies.
③By remodeling or repairing the delivery goods that
depend besides our company.
④When based on the reason which was not able to be
foreseen with the technical level at the time of
the shipment.
⑤In addition, when it is not in the responsibility
by the side of a manufacturer with a natural disas-
ter, disaster, etc.
●We can do neither conformity in the particular appli-
cation of this machine, nor compensation of guarantee
loss of the secondary value generated with a product.
Moreover, they are not a design and the manufactured
product for the purpose of the use as which very high
reliability and safety are required, and the uses
(atomic power, aerospace, infrastructure, medical equ-
ipment, etc.) concerning a human life.
About the use under such a use and environment, we
will carry out the outside of the scope of a guaran-
tee.

②DLC-500 (digital linear converter) connection
It sees from the front and connects DLC-500 to the left-hand side
of LS-700.
It shall be one set which was combined with DLC-500, and two-set
simultaneous connection is possible.
The above-mentioned number of sets is the number of sets at power-
supply-voltage DC12V.
The input of DLC-500 turns into an output of LS-700.
Wiring of a power supply is connected to LS-700.
Since there is possibility of the power supply line damage by fire
on a substrate when it is connected with DLC-500, please be sure
to connect with LS-700.

③DLC-500 and CH-500 (comparator module) connection
It sees from the front, and DLC-500 is connected to the left-hand
side of LS-700, and also CH-500 is connected to left-hand side.
The combination of three sets shall be one set and two-set simul-
taneous connection is possible.
The above-mentioned number of sets is the number of sets at power-
supply-voltage DC12V.
The input of DLC-500 turns into an output of LS-700.
Wiring of a power supply is connected to LS-700.
Since the power supply line on a substrate may be damaged by fire
when it is connected with other controllers, please be sure to

●Please do not make reconstruction and decomposition absolute.
●Be careful for there to be no faulty wiring in accordance with the wiring method
written in the instruction manual.
A product may be damaged with faulty wiring.
The breakage and failure by faulty wiring become the outside of the object of a
guarantee.
●In case you perform connection, since there is a possibility of receiving an ele-
ctric shock, please work turning off the power.
●Please do not add a big vibration and a shock to a product, or do not make it to
topple a product.
Moreover, please don't place a thing in piles on a product.
It may change and damage.
●When you check that it is a product of an order at the time of unpacking of pack-
ing and there are accessories, please be careful enough not to throw away.
●When there are accesories etc., please keep it not to be intermingled.

●Please carry out warming up 20 minutes or more from a power supply injection.
●Nothing should connect with the terminal which is not used.
●Please do not set it up near the device equipment(inverter, high-frequency gene-
rating equipment, and motor, etc.）that generates big surge.
●Please separate wiring from a high-tension wire or a power line as much as possi-
ble.
It becomes the cause of malfunction or failure by a noise.
●When the influence of thunder or serge can be considered, please install protec-
tion circuits, such as a surge arrester and a surge killer.
●When you connect loads, such as a relay lamp, please install a protection circuit.
●Please avoid use in the place where a rapid temperature change is caused and the
place where the vibration is intense.
●When it installs in a moist place, a product maybe damaged by dew condensation.
Please keep dew condensation from occurring in a moist place.
