*,** no Furnace head cannot be
initialized The furnace head cannot be moved to the final position. It might be blocked by an external
mechanical source! If this is not the case, please contact your local Service Center!
28
** Furnace head does not reach
the target position. The furnace head does not open/close correctly. The furnace head was manually moved or is
obstructed. The furnace head must only be moved using the keys intended for this purpose!
103 Program start blocked Starting a program is not possible due to a technical malfunction.
107 Incorrect time settings (date
/ time) The clock settings are incorrect. Please set a correct date and a correct time!
700 Supply voltage outside the
acceptable range The supply voltage is outside the acceptable range. Check the supply voltage.
701
*** no Start-up aborted due to an error The self-test of the furnace was interrupted by an error. It is not possible to work with the furnace!
Switch the furnace off and on again, once the error has been rectified.
702 Short power failure during a
program in progress A program in progress was interrupted by a short power failure. The program is being continued.

with the supply voltage indicated on the rating plate.
1310 Calibration reminder Some time has passed since the last calibration. Conduct a calibration procedure soon.
1600 T1 < B Enter an acceptable value for T.
1601 T2 < T1 Enter an acceptable value for T.
1602 T3 < T2 for T2 > 0,
T3 > 0 for T2=0 Enter an acceptable value for T.
1603 T4 > Tx (T1, T2, T3) Enter an acceptable value for T.
1604 T5 > T4 Enter an acceptable value for T.
1606 Temperature increase rate 2
too high If the holding temperature T2 is higher than 900 °C/1652 °F, the temperature increase rate t2 must
not exceed 50 °C/min. or 90 °F/min
1607 Temperature increase rate 3
too high If the holding temperature T3 is higher than 900 °C/1652 °F, the temperature increase rate t3 must

**
Current temperature after Start
> Tx + 80 °C/176 °F. Caution: Excess temperature! The program was aborted.
1626 Current Temperature
> 700 °C/1292 °F upon Start Sintering chamber is too hot for the start of a sintering program.
1627 Sintering chamber is too hot. Certain programs have a maximum starting temperature. If the furnace temperature is above the
maximum starting temperature, the programs cannot be started.
1632 Program memory write error Checksum of a firing program invalid. The firing program will be initialized with the original values.
1640 v1 > 0 and V1 = 0 If a predrying temperature is set, a predrying time must also be selected.
1641 v2 > 0 and V2 = 0 If a predrying temperature is set, a predrying time must also be selected.
1642 Predrying 2 active and Predrying
1 inactive
1650 PwrUnit Error Power-Unit. Check the fuse and the electric plug-in connections to the furnace head. The unit
is not ready for operation! Please contact your local Service Center.
