5.8.5 LDS3000 operating modes
The LDS3000 has three possible operating modes for vacuum applications:• GROSS• FINE• ULTRAThe LDS3000 operates with two selectable turbo pump rotational speeds:• 1000 Hz• 1500 Hz
Operating mode

In the operating mode GROSS the LDS3000 is in the measuring mode with the least

GROSS

sensitivity with considerable delayed response time at a very high inlet pressure of 18-9mbar (1000 Hz). The detection limit is 1·10 mbar·l/s. If you select the rotational speedof 1500 Hz, the detection limit falls due to the high compression of the turbo molecular-8pump down to 2·10 mbar·l/s with a maximum inlet pressure of up to 15 mbar.
Operating mode FINE

The operating mode FINE has - in comparison to GROSS - a higher sensitivity of
1·10

-11

mbar·l/s at 1000 Hz, with a reduced inlet pressure of 0.9 mbar.

Operating mode

In the operating mode ULTRA the LDS3000 is in the most sensitive measuring

ULTRA

configuration. This configuration implements both the highest pumping speed of 6 l/s
and the maximum sensitivity of 5·10

-12

mbar·l/s (at 1000 Hz) by varying the turbo pumprotational speed.

operation modes. For each operation mode and each range, the maximum transfer
pressures are also given.
The shaded areas in the lower range of the operation modes FINE and ULTRA are
only possible in industrial applications with a high technical effort.

The following shows two example configurations for transferring a vacuum connection
LDS1000 to a vacuum connection LDS3000.

Example 1: LDS1000 in GROSS mode
Depending on the working pressure of the respective applications you must select thedifferent configurations.
Working pressure between 1 mbar and 3 mbar
The maximum transfer pressure of the LDS1000 at 1020 Hz is 3 mbar. The minimum
detectable leak rate in this mode is 3.5 x 10

-10mbar l/sec. In the GROSS mode the

LDS3000 has a maximum transfer pressure of up to 18 mbar. However, the lowest

practical detection limit is only in the range 1 x 10 mbar l/s. With working pressures
between 1 mbar and 3 mbar only the GROSS connection of the LDS3000 with the-6

reduced response time and the lower sensitivity (up to 1 x 10 mbar l/s) can be used.
Working pressure of less than 1 mbar
If you operate the LDS1000 in this working pressure range you can select the FINE
connection of the LDS3000 with 1000 Hz. This range allows measurements withsensitivities to 1 x 10

-10mbar l/s.

Example 2: LDS1000 in FINE mode
Depending on the working pressure of the respective application there are also here
different configurations.
Working pressure between 0.2 mbar and 0.3 mbar
If you operate the LDS1000 in this working pressure range, you can retrofit the systemwith the LDS3000 in the operation mode FINE for both 1000 Hz and 1500 Hz. Selectpreferable the operation FINE with 1000 Hz. The operation mode FINE with 1000 Hz
produces reduced wear for the turbo pump.
Working pressure of less than 0.2 mbar
If you operate the LDS1000 in this working pressure range you can retrofit the system
to the operation mode ULTRA of the LDS3000. The pumping speed of the LDS3000 in"ULTRA" is higher by a factor of 2.7. This higher pumping speed results in a faster
response time. Select preferable the operation with 1000 Hz. This operation mode
produces reduced wear to the turbo pump.

5.8.7 Vacuum connection transfer from the LDS1000 to the
LDS3000
5.8.7.1 Vacuum connection transfer for the operating mode GROSS
The maximum transfer pressure with the LDS1000 at 1020 Hz is 3 mbar. The
minimum detectable leak rate in this operating mode is 3.5·10-10mbar·l/s. To transfer

this measurement configuration from the LDS1000 to the LDS3000 select the FINE
connection of the LDS3000 with 1000 Hz. For this reduce the transfer pressure with
the LDS3000 compared to the LDS1000 to < 1 mbar. We do not recommend the directtransfer to the GROSS connection of the LDS3000 due to the reduced response times
and the lower sensitivities of the LDS3000. We recommend that you only use theoperating mode GROSS of the LDS3000 for measuring leak rates that are larger the-5-6

10 to 10 mbar·l/s. For transfer pressures that are larger than 3 mbar you can only
use the GROSS connection of the LDS3000 with the reduced response time and thelower sensitivity.

5.8.7.2 Vacuum transfer for the operating mode FINE
The maximum transfer pressure with the LDS1000 is 3 mbar. The transfer pressure
for the LDS3000 with the FINE connection at 1000 Hz is reduced to 0.9 mbar. The
transfer pressure must therefore by less than 1 mbar to ensure a safe operation with
"FINE". For higher transfer pressures use the GROSS connection. Note here thereduced response time and the lower sensitivity.

5.8.7.3 Vacuum connection transfer for the operating mode FINE to
ULTRA
The pumping speed of the LDS3000 in "ULTRA" is higher than "FINE" by a factor of
2.7. The higher pumping speed reduces the response time and allows the trouble-freesystem retrofitting from the LDS1000 "FINE" to the LDS3000 "ULTRA". To reduce thewear of the turbo pump select the operation with 1000 Hz.

5.9 Interface protocol LDS1000/LDS2010
The interface protocol in the compatibility mode of the LDS3000 are almost identicalwith the standard protocol of the LDS1000/LDS2010.
Error numbers of the LDS3000 are converted via the interface into the corresponding
error numbers of the LDS1000 / LDS2010. Error numbers of the LDS3000 that haveno equivalent in the LDS1000 / LDS2010 are displayed in the group error number
E99.
The TIC interface protocol of the LDS2010 is no longer supported.
