AUTOSTART ON / OFF
The recirculating cooler 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 compressor 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.
Keep depressed enter
and
turn on the unit with the mains power switch.
For a short while the LED DISPLAY indicates the effective start mode:
AUTOSTART on.
AUTOSTART off.
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.
