■ 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 o.
■ 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.

9.7 Error messages
Error message Nature of the error Solution
“No temperature increase
measured”
Insucient temperature rise within
set time.
Switch o the mode or set it
dierently.
If the error still occurs, consider
using a heavier device.
“An internal communication error
occurred”
Communication problem between
printing that could not be resolved
automatically.
Switch o the device with the main
switch and wait a few seconds.
Then switch the device on again.
“Thermocouple 1 disconnected” Thermocouple 1 is not connected
or defective.
Connect a thermocouple or try a
dierent thermocouple.
“Thermocouple 2 disconnected” Thermocouple 2 is not connected
or defective.
Connect a thermocouple or try a
dierent thermocouple.
“Delta T timeout” The dierence in temperature
between the two sensors did not
fall below the set limit value within
the set time during a ΔT pause.
If desired, increase the pause time
for ΔT.
“The mains voltage has dropped
below the operating limit”
The supply voltage is lower than 80V. Check the mains voltage.
“The mains voltage has exceeded
the operating limit”
The supply voltage is above 280V. Check the mains voltage.
“The mains frequency has dropped
below 45Hz”
The AC frequency is lower than 45Hz. Check the mains frequency.
“The mains frequency has
exceeded 65Hz”
The AC frequency is higher than
65Hz.
Check the mains frequency.
“The power frequency is
too unstable for operation,
Attention: the ledge has not been
demagnetized!”
The AC frequency is unstable. Check the mains frequency.
“The environment temperature is
below -10°C”
The ambient temperature is lower
than -10°C.
Switch o 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.
