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 2,000 m 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. The lead wire resistance is small for RTD input use and please use the one which has no 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 recommended.
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.
