Installation
5Installation
5.1 Vacuum connection
Mounting orientation The installation position can be freely selected. The preferred position is a horizontal to
vertical position so that condensate and particles do not penetrate the measurement
chamber.
Connecting the trans-
mitter
Remove the protective cover, which is required during maintenance work.
Make the flange connection.
5.2 Electrical connection
Communication is effected, depending on the position of the address selector switch at
the transmitter, via Serial Interface RS-232 or via the RS-485 (address settable from 1-

Operation
6 Operation
6.1 Before switching on
After switching on the power supply, the transmitter is ready for operation. However, it is
advisable to wait for a stabilization period of 5-10 minutes before measurement, and to
operate the transmitter without interruption during the measurement process.
The pressure measured is independent of the type of gas.
6.2 Configuring the data exchange
Communication is carried out, depending on the address selector switch setting, via the
serial RS-232 interface using the relevant display units or via RS-485 using the Pfeiffer
Vacuum protocol:
●9600 baud
●8 data bits
●1 stop bit
●no parity
Parameter overview
Parameters are displayed in square brackets as a three-digit number in bold font. The
designation may also be stated if necessary.
Example: [P:312] Software version
Reading the actual
pressure value
[P:740]
Pressure value as the value to be queried and also as equalization (see below) are trans-
mitted by means of a string in the format "aaaabb", whereby "aaaa" is the mantissa and
"bb" the exponent with offset 20 of an exponential number. "aaaa" is therefore in the
range "1000" (for 1.000) to "9999" (for 9.999). The individual characters of the string are
the numbers "0" (ASCII 48) to "9" (ASCII 57).
Example: "104223" represents 1.042 x 10+3 mbar, "750015" represents 7.500 x 10-5
mbar.

Applied data types
6.4 Adjusting the transmitter
Before equalization, the transmitter should be operated at the relevant pressure for ap-
prox. 5 ... 10 minutes long (warm-up time).
For correct zero point equalization, the pressure in the vacuum chamber must be below
1·10-1 mbar.
With controller
DPG 101/DPG 109:
Equalize the transmitter as described in the instructions for the control units.
Via RS-232/RS-485: Evacuate the vacuum chamber to the pressure p < 1·10-1 mbar.
Set the pressure adjusting point [P:741] to «000» for low pressure and transmit.
Transmit the actual pressure value ([P:740] with «000000» ) for low pressure (repre-
sents p < 1.0 10-1); ==> ‘’ur’’ (under range).
– Is the low pressure exactly known, e. g. 4 mbar; send [P:740] with value «400020».
Vent vacuum chamber to atmospheric pressure with air or N2; afterwards wait about
10 minutes.
Set the pressure adjusting point [P:741] to «001» for high pressure and transmit.
Set the actual pressure value [P:740] to the atmospheric pressure («100023» for 1000
mbar). Is the atmospheric pressure actually present, e. g. 980 mbar; send [P:740] with
value «980022».
