Setting the process parameter
Setting the time for automatic shut down:
➨ Press key Δp▲ or Δp▼.
☞ ”Set” and the clock symbol and the time for automatic shut
down are displayed for approx. 1 s (factory-set 15 min).
☞ With a second tip within one second or continuous pressing:
➨ Press key Δp▲ or Δp▼ to set value for time for shut down
(0 to 200 minutes).
☞ The value for the shut down time is stored as the new set
point when the key is released.
Setting the lower pressure value (condition for automatic shut
down; factory-set: 20 min.):
➨ Press p▲ or p▼.
☞ ”Set p”, ”arrow down” and the lower pressure value are dis-
played for approx. one second.
☞ With a second tip within one second or continuous pressing:
➨ Set the lower set point by pressing key p▲ or p▼.
☞ The lower pressure value is stored as the new set point when
the key is released.
Note: Choose the pressure value in a range which is achieved
in the vacuum system if there is no more gas or vapour genera-
tion at the vacuum connections.
It is recommended to select a pressure value which is approx.
10 mbar higher than the ultimate pressure value achievable in
the system (normally the ultimate vacuum of the pump).
Setting the upper pressure value (condition for restart; fac-
tory-set 200 mbar):
➨ While key MODE is pressed, press key Δp▲ or Δp▼.
☞ ”Set p”, ”arrow up” and the upper pressure value are dis-
played for approx. one second.
☞ With a second tip within one second or continuous pressing:
➨ Set the upper pressure value by pressing key Δp▲ or Δp▼.
☞ The upper pressure value is stored as the new set point
when the key is released.
Note: If the value of the upper pressure value is set below the
value of the lower pressure value, the upper pressure value is
inactivated. The pump starts immediately.
