E A4
Event
Temperature increase too low on full power
This error message refers to a kiln problem.
Possible causes:
• Defective mains fuse / phase, broken heating elements
• Heating elements too old (high temperatures)
• Short circuit on thermocouple or compensating wire
• Defective contactor (often occurs during firing process)
E A5
Event
Kiln does not follow programmed temperature increase
Other than Event A4, values for temperature increase have been set too high and
the kiln cannot follow the programmed values. This message is displayed only if
enabled in the configuration.
E A8
Event
Ramp has been continued automatically
If the kiln cannot follow the temperature increase, the ramp will be intermitted. If the
controller finds the kiln unable to catch up with the temperature the firing will continue
and this message will be displayed for one minute.
E A9
Event
SKIP ramp interrupted
If the controller failed to reach the end temperature in an uncontrolled ramp it will
continue with the next segment - see section "Uncontrolled ramps (SKIP)". This
message is informative and is displayed for one minute.
E B3
Event
Firing process interrupted after power failure
After re-establishing power supply, the firing process has been interrupted because,
for example, kiln temperature has dropped too much. A digit shown after the comma
will provide further information concerning the cause (e.g. B 3.4 = temperature
dropped too much).
If this message is displayed immediately after the controller has been turned on, you
may ignore it. This indicates that the controller was turned off while the firing process
and program were still operational. Simply continue working by entering a program.
