Autostart

Possible parameters:

on - AUTOSTART on

off - AUTOSTART off (Factory setting)


Note:
The temperature system 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 „, resp. R OFF on
the VFD-COMFORT-DISPLAY. A complete shutdown of the main functional
elements such as heater and circulating pump is effected simultaneously.
The values set on the Cryo-Compact Circulator remain stored, and the unit is
returned to operation by pressing the start/stop key (in manual control mode).
In remote control mode, the values need to be resent by the PC via the
interface.
Should such a safety standard not be required, the AUTOSTART function
(automatic start mode) may be activated, thus allowing the start of the
instrument directly by pressing the mains power switch or using a timer.

The AUTOSTART function can only be used, if setpoint setting is carried
out via >keyboard< or >eprog< or >ext. Pt100<.


Warning:

For supervised or unsupervised operation with the AUTOSTART function, avoid any
hazardous situation to persons or property.
The instrument does no longer conform to N.A.M.U.R. recommendations.

The safety and warning functions of the instrument should always be used to their
fullest capacity.
