9.4. General error messages
Display Description
Err. 0
Internal data error
 Heating error.
 The kiln temperature is not increasing as
required.
Err. 1
The kiln has been on full power for 15 minutes,

but the temperature has not increased by at
least 2°C.
Thermocouple or wiring for thermocouple
Err. 2
disconnected.
Err. 3
Thermocouple wired incorrectly
Cooling error

The kiln has been on zero power for 30
Err. 4

minutes, but the kiln temperature has not
fallen by at least 1°C.
Set kiln temperature exceeded.
Desired temperature
Err. 5
below 100 °C
over 100 °C, below 200 °C
over 200 °C, below 600 °C
over 600 °C
The maximum duration of the firing process
Err. 6
exceeded.
Err. 7
The maximum room temperature exceeded.
Note:
 Each of the listed error messages leads to the termination of the firing process.
 Terminating the firing process protects the kiln from damage.
 The alarm buzzer will sound once per second.
 To reset the controller, turn off the power to the device and have the fault investigated and rectified by your
installer or kiln service engineer.
Cause of error / Troubleshooting
The controller cannot be repaired on site and
must be sent to the manufacturer for repair.

65 / 291 - EN -
Kiln door or lid not completely closed.
Defective door switch
Door switch needs to be adjusted.
Heating element circuit open
Heating elements too old
Electrical power phase failure
Contactor failure
Get thermocouple and wiring checked.
Replace thermocouple if necessary.
Kiln temperature apparently below
-40°C
This is an installation fault.
Get wiring checked.
Contactor failure
(contacts possibly welded)
Thermocouple disconnected or resistance
too high.
The kiln temperature has exceeded the
desired temperature by a preset limit.
The cause of the excess temperature must
be determined.
The contactor is not working (contactor
hanging/replace contactor).
please contact ROHDE Service.
The internal temperature of the controller
has exceeded a factory-set limit value.
Factory set to 50°C.
Possible causes:
insufficient or incorrect ventilation of the
­
kiln
operating location too small
­
ventilation grille blocked
­
exhaust air flap not closed
­
controller mounted too close to the kiln
