option, or confirm a set value.
Use the arrow keys to select a function or set a value. Short
press for single steps, press and hold for fast counting.
5.3 Alarm messages
Alarms and warnings are indicated on the display using error codes. Important
error code descriptions can be found in the appendix. If you are unable to rectify
a fault, contact Technical Service.
Alarm:
In the event of an alarm, the control LED lights up. The temperature control is
stopped. At the same time, a continuous acoustic signal sounds and an error
code is shown on the display. The acoustic signal can be deactivated by pressing
the [OK] key. The fault causing the alarm must be remedied. A restart is
required.
Warning:
In the event of a warning, the temperature control application is not interrupted.
A signal tone is emitted at intervals. The display alternates between the actual
temperature and the error code. The acoustic signal can be deactivated by
pressing the [OK] key. If the underlying cause of the warning is remedied, the
signal tone ceases. Depending on the cause, warnings may cease automatically
after a period of time, e.g. when the device cools down.
