8.1 Low level protection

Evaporation may cause a slowly water loss. If
the level is lower than app. 20 mm, a mechan-
ical safety temperature limiter cuts off the
complete voltage supply.

If lack of water was the problem, the limiter
can be deactivated once water has been add-
ed.

To do this, press the button at the rear of the
water bath until a noticeable latching occurs.
8.2 Unlock the safety temperature limiter
Two sensors monitor the temperature on the bottom of the bath.
If the temperature on the bottom of the tank reaches above 110 °C, the LED display indicates:
E1
.
Immediately switch off the device with the mains switch and rectify cause of fault. Frequently it is a low
water level in the tank (

7.4).

Above approx. 150 °C bottom temperature a
mechanical safety temperature limiter cuts off
the complete voltage supply. Thereupon the
LED display goes out.
This protective device is not self-cancelling
according to DIN EN 61010-2-10.

First, the cause of the overtemperature must
be found. If lack of water was the problem, the
limiter can be deactivated once water has
been added.

To do this, press the button at the rear of the
water bath until a noticeable latching occurs.

The safety temperature limiter must not be deactivated when a mechanical or electri-
cal fault is suspected.
If necessary, contact the authorized LAUDA Service agents or the LAUDA Service
Constant Temperature Equipment (

8.6).
8.3 Cleaning

Withdraw the equipment mains plug before cleaning!
Cleaning can be carried out with water to which a few drops of surfactant (washing-up liquid), have
been added and using a damp cloth.
