RRORS
Cause (cont.)
Set point is out of range. This is a
temporary error to alert you that you
have crossed the allowable boundary
for the function you are setting.
Chamber thermocouple leads
reversed. Thermocouple is a type “K”.
Polarity is coded as red (-) and yellow
(+).
Filter thermocouple leads reversed.
Balance not communicating; weight,
time and date not received.
Error Code (cont.)
E009
E010
E011
E012
Solution (cont.)
The furnace will beep for 3 seconds while dis-
playing this error and then return to normal
operation. The setpoint will revert to its previ-
ous valve. Chamber temperature is to be less
than 674°C; Filter temperature is to be less
than 900°C.
If the thermocouple was just replaced, then
reverse the leads.
Check to see if E003 comes up while the unit
is NOT running a program.
If this error occurred during operation, perform
hidden key routine #7 to verify the tempera-
ture. If the displayed temperature is erratic,
replace the analog board.
See above to proceed.
Follow steps in E008. If the balance needs to
be replaced, see BALANCE section of this
manual.
