Error Messages - Bessey SBH Series User Manual

9.7 Error messages

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.
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.
The ambient temperature is higher
than 70°C.
An effective current from the mains
is too high.
An effective current through the coil
is too high.
An effective current through the
capacitor is too high.
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.
Switch off the device and wait until the
ambient temperature has dropped
below 70°C (158°F). If the temperature
is within the limit and the error still
occurs, please contact your supplier.
If the problem persists, contact your
supplier.
Switch the device off and on and try
again. If the problem persists, contact
your supplier.
Switch the device off and on and try
again. If the problem persists, contact
your supplier.
