Characteristics

W T≤1200C

Fe-Cr-Al-Mo wire

Compared with the ordinary iron chromium aluminum wire resistance, higher temperature and more durable

W T≤1400C

SiC heater

Using high temperature, anti-oxidation, corrosion resistance, long life, small deformation, easy installation and maintenance.

W T≤1750C

MoSi2 heater

Suitable for ultra high temperature heating, long service life, high calorific value and economic price

Problems

Reason

Solution

Open Power Lock, no power indication

Fuse (4A) in control panel is broken

Check control panel, and replace fuse

Green Power indictor is off, but Red open circuit indicator is On

Fuse ( 50A) in main power circuit is broken

Open the cover of front panel and replace the fuse

No current shows in meter , but has Max. Voltage

Heating element broken

Find broken heating rod, and replace it

Controller display panel SV shows“ OraL”

Thermal Couples broken

Replace Thermal couples ( B type )

Controller display panel SV shows“ HI AL”

Furnace temperature > 1700C, Protection from Alarm

Cool furnace down, and find reason why temperature is so high ( program setting may be wrong)

Power and heating element are OK, but furnace can’t be controlled by program.

Controller or related circuit may be damaged

Heck controller.

Program running, but furnace can not be heated, or real temperature is far behind the setting value

oPL or oPH value is too low due to local voltage lower or frenquency different

Incraese “oPL” and “oPH” value till current meter shows “ 120 A – 140 A”, and program runs smoothly

During heating below 300C, the temperature value ( PV) is not stable, and doesn’t match with setting program (SV)

It is normal because the furnace comes with a high temperature thermocouple, which is not sensitive at temperature below 300C

Don’t worry. Let the furnace heat to 300C, then thermocouple will function stably with program. If the PV value at 300C is still less than that of SV, you may need to increase OPL value a little.
