3 Intended use
This section defines the purpose of the unit so that the operator can operate the
unit safely and avoid misuse.
JULABO circulators are laboratory devices that are designed for temperature
control applications with liquid media in a bath tank or with a cooling machine.
An external loop circuit can be connected to the pump connectors so that the
temperature of the bath media can be kept constant.
Only use the device if it is in technically perfect condition and only use it in
accordance with its intended use. Be aware of safety issues or hazards and
comply with the operating manual! In particular, always immediately rectify
faults that could impair safety!
The circulators are not suitable for direct temperature control application of
food, other consumables or pharmaceutical or other medical products.
The devices are not suitable for use in an explosive environment.
The devices are not intended for use in living areas. They may cause interference
with radio reception.

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.
Adjustable high temperature cut-off
The high temperature cut-off prevents overheating of the heater.
• If the temperature of the working temperature reaches the set protective
temperature, an error message appears on the display. The pump and
heater are switched off. A restart is required.

Safety

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.
Low liquid level protection
A level switch recognizes when the bath fluid fill level in the bath tank is too
low. The device has a two-stage warming system to prevent overheating of the
heater or dry running of the pump.
• The low liquid level warning is triggered when the liquid level in the bath
tank is about half the full level. A warning message appears on the display.
The bath fluid should be topped up.
• 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. A warning message appears on the display. A restart is
required.

standard temperature
applications
5.2 Function description
This section describes the function of the device.
The circulator can be mounted on any bath tank with a volume up to 50 liters.
The circulators are used for internal and external temperature control, and
depending on the device combination and accessories used can work in a
temperature range between -50°C and +200°C.
When mounted on a bath tank the circulator is a heating circulator, when
combined with a cooling machine it is a refrigerated circulator.

5.3.1 Key description
The device is operated using the key panel. This is used to control all menu
functions and make entries.
Key Function
The [OK] key is used to start a temperature control application or to stop a
running temperature control application.
The [OK] key enables a selected function, opens a menu option, or confirms a
set value.
Use the arrow keys to navigate in the main menu, select a function, or set a
value. Short press for single steps, press and hold for fast counting.
The [MENU] key is used to bring up main menu, to undo an entry, or to jump
back one step in the menu.
5.4 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.
