Caution
Be sure to check that the power supply is off in connecting each cable. If the work is done while the power is on, there may have the case that
electric shock to the operator or even may have damage to the instrument.
Before supplying the power, check that the indication of power supply voltage/specifications for the instrument and the power going to supply
should be the same. If they are not equal, contact with us.
If you use the instrument without checking them, it may cause a damage in the instrument or electric shock to the operator.
Please consult Co. about the report when not matching. There is danger of causing damage and the electric shock of this instrument when
using it like the uncertainty.
Earth wire should be grounded securely.
When earth wire is not connected, it may cause a malfunction of the instrument or electric shock to the operator.
Before using a new instrument or exchanging the strain gage applied transducer for a new one, be sure to make calibration.
If calibration will not be made, the correct measuring results may not be obtained nor which may cause malfunction in the instrument and there
may exist damage in peripheral equipments. Besides, even though calibration has been made, there may occur the similar case when the results
are not correct, so make calibration, again.
In case of using the instrument, check that the connections are executed properly. If not connected properly, the correct measuring result will
not be obtained, nor it may cause malfunctions of the instrument, damage to the peripheral equipments or even more serious accidents.
When change of setting is made carelessly on the instrument during measurement, correct measured results may not be obtained and it may
cause malfunction in the instrument and even have the possibility of damage in peripheral instruments.
Don’t shock the instrument such as throwing something on it.
If neglected, it may cause destruction of the parts and damage to the electrical circuits.
Don’t remove the cover of this instrument, don’t peel off the panel sheet, and additionally, take this instrument apart.
It may cause a damage on the case and panel sheet, and ruins the environmental factor and operativeness.
At the time of shipment from the factory, the instrument has been plated with a clear sheet on the panel sheet for protective purpose.
In case of application, use the instrument after removing the clear sheet first.
Don’t push the panel sheet on the instrument with the excessive strong force nor push it with sharp edge object such as a driver. If neglected,
it may cause a damage to the panel switch and even have the possibility of damage to resist to environments or operational performance.

2．Connecting method
2-1. Notes for connecting wires
• When you connect wires, please proceed after turning off the power supply without fail.
• Please do not connect AC power supply until the installation is completed. There is no switch that switches
power supply ON/OFF in the main body.
• Please keep the cable connected with the main body away from the noise source, such as power supply line
and I/O for the control, etc. as much as possible.
• Please set the conduit wiring to be exclusive wiring, and avoid sharing with other lines.
• Please make sure to connect grounding wire, and the earth is to be the D class with single earth. Please do
not share with the earth of the power supply system.
• Please apply the shielded cable for connecting with the external control input and contact output, and the
shield is to be connected with the shield connector of the terminal, or main body.
2-2. Connection with load cell
(1) Connection of load cell and TMD-100
- When the tension force is measured with tension type or tension/compression type load cell, please connect the “green” with terminal No.
B1 or B2, and the “Blue” with terminal No. D1 or D2 respectively.
- As there may be the case that the wiring color is different form the standard, please confirm it with the inspection data sheet of the load
cell before connecting.
- When the length of CAB-502 is more than 30 m totally, there may have the case the accuracy becomes out of warranty because the
resistance of cable makes the input voltage of the instrument decrease.
- When the length of CAB-501 is more than 100 m totally, there may have the case that the remote sensing function will not work enough,
and the accuracy becomes out of warranty because of the resistance of cable.
