4. Trouble shooting for typical Problems
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 – 140A”, 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 functionstably with program. If the PV valueat 300C is still less than that of SV, youmay need to increase OPL value a little. |
