Operating procedures
22
Caution:
If the circulator is turned off with the mains switch (1a), the refrigerating unit
is not switched off simultaneously.
Turn off the refrigerating unit with the mains switch (1b) as well.
Danger of freezing when water is used as bath fluid!
6.3. Automatic / non-automatic start mode

Keep depressed the key and

turn on the circulator with the mains power switch.
For a short while the LED temperature DISPLAY indicates the
effective start mode:

AUTOSTART on.

AUTOSTART off.
NOTE:
The circulator has been configured and supplied by JULABO
according to N.A.M.U.R. recommendations. This means for the start
mode, that the unit must enter a safe operating state after a power
failure (non-automatic start mode). This safe operating state is
indicated by „OFF“ on the LED temperature display. A complete
shutdown of the main functional elements such as heater and
circulating pump is effected simultaneously.
Should such a safety standard not be required, the AUTOSTART
function (automatic start mode) may be activated, thus allowing the
start of the circulator directly by pressing the mains power switch or
using a timer.
Warning:
For supervised or unsupervised operation with the AUTOSTART function,
avoid any hazardous situation to persons or property.
The circulator does no longer conform to N.A.M.U.R. recommendations.
Take care you fully observe the safety and warning functions of the circulator.
The instrument is not suited for unsupervised continuous operation.
