Permissible rotation speed range
Settings in the rotation speed mode or stand-by mode are subject to the permissible rota-
tion speed range of the respective vacuum pump (technical data). The electronic drive unit
adjusts the set rotation speed automatically to the next valid value.
Set the rotation speed setting mode
1. Set the parameter
[P:707]
to the required value in %.
2. Set the parameter
[P:026]
to "1".
3. Check the set rotation speed (parameter
[P:308]
or
[P:397]
).
8.5.4 Auto boost
Option: Pressure sensor
● This function is only available in the version with pressure sensor.
● Pumping explosive atmospheres when using the pressure sensor is not permitted, as
the sensor does not have ATEX approval.
If a threshold value set at the factory is exceeded, the vacuum pump runs for max. 30 s with 120 % of
the current selected set rotation speed and the green LED flickers. The boost mode is then deactivated
by the software for 5 mins (recovery time).
Setting related parameters
1. Set the parameter
[P:011]
to "1".
2. Check the set rotation speed (parameter
[P:308]
or
[P:397]
).
3. Check the set rotation speed (parameter
[P:309]
or
[P:398]
).
8.5.5 Auto standby
Option: Pressure sensor
● This function is only available in the version with pressure sensor.
● Pumping explosive atmospheres when using the pressure sensor is not permitted, as
the sensor does not have ATEX approval.
If a specific intake pressure is not reached [P:730], the electronic drive unit automatically reduces the
rotation speed. If the intake pressure is exceeded [P:732], the electronic drive unit increases the rotation
speed again to the original value. If operating priority is 1 = "remote", auto standby cannot be executed
and warning Wrn037 is displayed.
Setting related parameters
1. Set the parameter
[P:002]
to "0".
2. Set the parameter
[P:006]
to "1".
3. Check the set rotation speed (parameter
[P:308]
or
[P:397]
).
Setting the auto standby rotation speed
1. Set the parameter
[P:717]
to the required value in %.
2. Set the switch-on threshold with parameter
[P:730]
.
3. Set the switch-off threshold with parameter
[P:732]
.
4. Check the set rotation speed (parameter
[P:308]
or
[P:397]
).
Operation with auto standby function
► Hold the
button pressed for longer than 5 s.
– This will change parameter
[P:006]
.
– To confirm the command, the yellow LED flashes for 1 second after releasing the button.
● Parameter
[P:002] = 1
: You press the
button for 5 s and switch off the auto standby.
[P:006] = 0
. The standby pre-selection remains activated.
● Parameter
[P:002] = 0
: You press the
button for 5 s and switch off the auto standby.
[P:006] = 1
. The standby pre-selection remains deactivated.
