9.4.3. Autostart
Possible parameters:
on - Autostart on
off - Autostart off (Factory setting)
Note:
The circulator has been configured and delivered 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” or
“R OFF” on the VFD-COMFORT-DISPLAY. A complete shutdown of the
main functional elements such as the heater and circulating pump is
effected simultaneously.
The values set on the 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 unit
to be started directly by pressing the mains power switch or using a
timer.

The AUTOSTART function can be used only if the setpoint is set via
>keyboard<, >eprog<, or >ext. Pt100<.
Warning :
For supervised or unsupervised operation with the “AUTOSTART“ function avoid any
hazardous situation to persons or property
Take care to fully observe the safety and warning functions of the circulator.
9.4.4. Off-Mode
OFF-Mode
Normally the circulating pump is switched via the start/stop signal.
However, if circulation should be maintained even in the -off- condition,
the parameter >pump on< needs to be set.
Possible parameters:
P.on Circulating pump in continuous operation
P.off Circulating pump linked to Start/Stop (factory setting)
