Alarms, errors and warnings
All alarms, error messages and warnings triggered on the device appear in
text form on the display.
Alarms affect safety. The components of the device, such as the pump,
switch off. The device emits an sound. Once the cause of the fault has been
eliminated, the alarm can be canceled with the Enter key.
Refer to
Chapter 10.2 “Alarms” on page 147 for a list of alarms.
Warnings do not have a significant effect on safety. The device continues
to operate. The device will make a continuous noise for a short period of
time. Warnings are issued periodically. Once the cause of the fault has been
eliminated, the warning can be canceled with the Enter key.
If an error occurs, the device emits a sound.
If this happens, switch off the device at the mains switch. If the error occurs
again after switching on the device, make a note of the error code and the
corresponding description and contact the LAUDA Constant Temperature
Equipment Service department. You will find the contact information here
Chapter 14.4 “Contact LAUDA” on page 160.
