Note:
It is recommended to select a pressure value which is
approx. 10 mbar higher than the ultimate pressure value achiev-
able in the system.

to set the value for the time for shut down
(1 - 200 min).
☞
The value for the shut down time is stored as the new set
point when the key is released.
☞
If the actual pressure falls below the lower set point, the
time for automatic shut down starts to run. The time for au-
tomatic shut down is reset if the actual pressure rises higher
than the lower set point (with a hysteresis of 3 mbar).
The process control stops when the time for shut down has
elapsed. The vacuum pump is switched off and the coolant valve
is closed.
☞
Pump starts again in case of great pressure increase.
☞
If the actual pressure is rising above the upper set point, the
pump starts again (corresponds to starting by pressing key
START/STOP).
☞
The process control can be stopped manually at any time
by pressing key START/STOP.
