Faults and error messages
EDDYTHERM is equipped with an overload protection (automatic fault detection unit) to prevent damage to the
device or to the roller bearings being heated.

Appears if a temperature probe is not connected in the “temperature hold” or
“temperature shutoff” operating modes.
Remedy: Connect the temperature probe.
Appears when the heater is operated in the “temperature hold” or “temperature
shutoff” mode and the temperature probe is not mounted or is improperly mounted
on the workpiece.
Remedy: Mount the temperature probe correctly on the workpiece.
Appears when the heater is operated in the “temperature hold” or “temperature
shutoff” mode and heating takes place so slowly that the probe registers
no temperature increase. This may occur, for example, with extremely large
workpieces.
Remedy: If the reduced-power heating option has been activated, deactivate
it; or heat the workpiece in the “timed shutoff” mode; or deactivate the
overload protection.
Deactivating the overload protection (the auto-shutoff feature)
This protective function can be circumvented by pressing the “temperature shutoff”
and “temperature hold” keys simultaneously. Even if the overload protection is
deactivated, it is possible to switch between the two operating modes (temperature
shutoff and temperature hold) by pressing the corresponding key.
The letter d (for disabled) now flashes in the display. The overload protection can be
reactivated by pressing the STOP key.
Appears when the heater is operated in the “temperature hold” or “temperature
shutoff” mode and the temperature probe is warmer than the workpiece on which
it is mounted.
Remedy: Wait briefly for the temperature probe to reach the same
temperature as the workpiece.
Appears when the attached temperature probe is heated above its maximum
allowable temperature (140°C/284°F for the clip-type probe, 240°C/464°F for the
magnetic probe). This type of fault can take place only when operating in the
“timed shutoff” mode.
Remedy: Use the magnetic probe instead of the clip-type probe (up to
240°C/464°F).
When monitoring workpieces that need to be heated to high temperatures
during the “timed shutoff” mode, do not use either of the EDDYTHERM
temperature probes; use a hand-held thermometer or infra-red temperature
sensing device instead.
