10. Do not use this product at any place with possible thermal accumulation due to direct sunlight or heat
radiation.
11. Install this product at place under 2,000m in altitude.
12. Attach the bractets(2pcs) on the fixed halls and tighten with a screwdriver. Fixing torque is about 14.7
N
cm (1.5 kg cm)
13. When the product gets wet, the inspection is essential because there is danger of an electric leakage
or fire.
14. Use a compensating cable with thermocouple.
15. For R.T.D input use a cable which is a small lead wire resistance and without resistance difference to
3 wires.
16. To avoid inductive noise to input wires, seperate from the power and output wires.
17. Keep input wires away from output wires and use shielded wires to earth.
18. Use non-grounded sensor to R.T.D and thermocouple.
19. If there is excessive noise from the power supply, using insulating transformer and noise filter is rec-
ommended. The noise filter must be attached to a panel grounded, and the wire between the filter
output side and power supply terminal must be as short as possible.
20. It is effective to use a twisted cable for power supply against noise.
21. If alarm function is not set correctly, alarm output can not be operated at a trouble.
22. When replacing the sensor, please turn OFF the power supply.
23. Use an extra relay when the frequency of operation is rather high. In this case, SSR output type is
recommended.
Electromagnetic switch : Proportional cycle time is Min. 20 sec
SSR : Proportional cycle time is Min. 1 sec
Contact output life : Mechanical : Min.10 million times (no load)
Eletrical : Min. 100 thousand times (rated load)
SSR drive pulse voltage, 4 ~ 20 mA DC are not insulated with internal circuit.
24. The instrument has IP65. Use rubber packing when installing the instrument to panel.
25. Do not connect anything to the unused terminals.
26. After checking polarity of terminal, connect wires at the correct position.
27. When this product is connected to a panel, use a circuit breaker or switch approved with IEC847-1 or
IEC947-3.
28. Install the circuit breaker or switch at near place for convenient use.
29. Write down on a label that the operation of circuit breaker or switch disconnects the power since the
devise is installed.
30. For the continuous and safe use of this product, the periodical maintenance is recommended.
31. Some parts of this product have limited life span, and others are changed by their usage.
32. The warranty period for this product including parts is one year if this product is properly used.
33. The heater power supply and the instrument power supply should be connected using the same
power supply when a heater break alarm.
34. When the power is on, the preparation period of contact output is required. In case of use for signals
of external interlock circuit, use with a delay relay.
35. When changing a contorller to extra one, please check all parameters.
