3. 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. |
