Description
Warning of a danger zone. Note operating manual
Warning about hot surface
Warning of cold surface
Read operating manual before switching on
4.5 Safety function
Technical protective devices provide for safe operation. If a safety function is
triggered, the operator is alerted with a message on the display and an acoustic
signal.
Overheating protection
The overheating protection prevents overheating of the heater.
• The protective mechanism is triggered when the device recognizes a
temperature difference of more than 20 K between the working
temperature sensor and the safety temperature sensor. Am error message
appears on the display. A restart is required.

Safety
12
Low liquid level protection
A level switch recognizes when the bath fluid fill level in the bath tank is too
low. The unit has a warning system to prevent overheating of the heater or dry
running of the pump.
• The low liquid level alarm is triggered when the float reaches its lower limit
stop. The device switches off the pump and heater. A continuous signal
tone sounds. An error message appears on the display. A restart is required.

5.2.1 Key description
The device is operated using the key panel. This is used to control all menu
functions and make entries.
Key Function
Press [OK] to start a temperature control application or to
stop a running temperature control application.
Press [OK] to enable a selected function, open a menu
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.
