9.7 Error messages
Error message
"No temperature increase
measured"
"An internal communication error
occurred"
"Thermocouple 1 disconnected"
"Thermocouple 2 disconnected"
"Delta T timeout"
"The mains voltage has dropped
below the operating limit"
"The mains voltage has exceeded
the operating limit"
"The mains frequency has dropped
below 45Hz"
"The mains frequency has
exceeded 65Hz"
"The power frequency is
too unstable for operation,
Attention: the ledge has not been
demagnetized!"
"The environment temperature is
below -10°C"

■ After pressing "STOP", place the sensor(s) on the side of
the pole.
■ By pressing "STOP", the workpiece is
demagnetized automatically.
■ Wear heat-resistant gloves. Place the ledge with the
workpiece on a clean surface or if the heater is equipped
with a swivel arm, swivel the ledge forwards into the
positioning cam, slide the workpiece off.
■ Fit the workpiece without delay and prevent cooling down.
The heater continuously monitors process parameters and
other variables that are important for the heating process to
run as smoothly as possible.
If something is wrong, the heating process usually stops, and
a pop-up screen appears with an error message.
Nature of the error
Insufficient temperature rise within
set time.
Communication problem between
printing that could not be resolved
automatically.
Thermocouple 1 is not connected
or defective.
Thermocouple 2 is not connected
or defective.
The difference in temperature
between the two sensors did not
fall below the set limit value within
the set time during a ΔT pause.
The supply voltage is lower than 80V.
The supply voltage is above 280V.
The AC frequency is lower than 45Hz.
The AC frequency is higher than
65Hz.
The AC frequency is unstable.
The ambient temperature is lower
than -10°C.
Solution
Switch off the mode or set it
differently.
If the error still occurs, consider
using a heavier device.
Switch off the device with the main
switch and wait a few seconds.
Then switch the device on again.
Connect a thermocouple or try a
different thermocouple.
Connect a thermocouple or try a
different thermocouple.
If desired, increase the pause time
for ΔT.
Check the mains voltage.
Check the mains voltage.
Check the mains frequency.
Check the mains frequency.
Check the mains frequency.
Switch off the device and wait
until the ambient temperature has
risen above -10°C (14°F). If the
temperature is within the limit and
the error still occurs, please contact
your supplier.
