② Installation
●
For NX9, 7, 3 and 2, attach the brackets (2 units) on the fixed halls and tighten with a
screwdriver.
Fixing torque is about 14.7N. cm (1.5kg.cm). NX1 and NX4 has a plastic bracket.
(Care should be taken not to tighten forcedly.)
③ Caution on terminal connections
●
Use a compensating cable with thermocouple.
● For R.T.D input use a cable which is
a small lead wire resistance and without resistance
difference to 3wires.
●
To avoid inductive noise to input wires seperate from the power and output wires.
●
Keep input wires away from output wires and use shielded wires to earth.
●
If the wiring has noise, use the following step: connect a surge absorber to the conductor
coil side if the conductors are connected to the load output, such as the relay contact output.
●
Use an insulating transformer with a noise filter when the power suppy has much noise.
●
Noise filter should be mounted on a panel which has been earthed and the wiring between
the noise filter output and the instrument power terminals should be shorten.
●
It is effective to use a twisted cable for power supply against noise.
●
The heater power supply and the instrument power supply should be connected using the
same power suppy when a heater break alarm.
●
Time for preparation of contact output is required at power ON. When the output signal is
used for an extenal interlock circuit, connect a delay relay.
④ For load circuit connection
●
Use an extra relay when the frequency of operation is rather high. In thic case,
SSR output type is Recommended.
•
Electromagnetic switch : Proportional cycle time is Min. 30sec
•
SSR : Proportional cycle time is Min. 1 sec
•
Contact output life : Mechanical : Min. 10 million times (no load)
Electrical : Min. 100 thousand times (rated load)
•
SSR drive pulse voltage, DC 4~20mA are not insulated with internal circuit.
Use non-grounded sensor to R.T.D and thermocouple.
⑤ For waterproof (Waterproof type)
The instrument has IP65. Use rubber packing when installing the instrument to panel.
Please attach the rubber in correct way.
⑥ Caution on key operation / trouble
●
If alarm function is not set correctly, alarm output can not be operated at a trouble.
Be sure to check the alarm operation.
●
If the input cable is disconnected, the display shows “ ”.
When replacing the sensor, please turn OFF the power supply.
⑦ Other
Do not use organic solvents such as alcohol, benzine when cleaning. (Use neutral detergent)
