5. Precautions on Handling
Warning and caution
24. About corrosion of the sensor
Do not use the sensor of the unit with alkaline metals, metal vapors, various oxidized metals,
carbon monoxide, carbon, phosphorous, selenium, arsenic or other reducing elements or a
reducing atmosphere to avoid corrosion of the sensor.
25. About the standalone overheat preventive unit
When the difference between the set temperature for the standalone overheat preventive unit
and that of the controller is small, the overheat preventive unit may activate, indicate [
ER07
]
and operation may stop. Set the temperature for the overheat preventive unit at a temperature
higher than that of the controller by at least 100
℃
. (This unit is a high temperature furnace and
may often present overshoot at a lower temperature setting. Use this overheat preventive unit
for the purpose of protecting the unit.) This is set at 1250
℃
at the factory shipping.
26. About the installation of the exhaust unit
When you use the optional exhaust unit for this unit, connect the ground wire included with the
exhaust unit to the chassis of the main body.
27. Precautions on using N2 gas
In the N2 gas atmosphere, nitriding on the heater surface proceeds due to a high temperature,
which prevents formation of a protective film, and the upper limit of operation temperature will be
lower unlike in the air atmosphere. (Due to the upper use limit in the N2 gas atmosphere.)
Keep the temperature in the range of 100
～
900
℃
when operating the unit in the N2 gas
atmosphere.
28.Take care for the fan at the back of the unit.
Take care not to pinch your finger in the fan at the back of the unit.
