3. Installation
3.1. Preparations For Installation
CAUTION
Unauthorised modifications or alterations to the unit are not allowed.
Installation location:
Indoor; max. 2000 m above mean sea level.
The following is applicable for open buildings and operations rooms which are not fully air
conditioned:
Temperature:
+5°C - +40°C.
Relative humidity:
5 - 85%, non-condensing.
Air pressure:
86 kPa - 106 kPa
3.2. Vacuum Connection
CAUTION
Dirt and damage have an adverse effect on the function of these vacuum
components.
Please take account of the instructions with regard to cleanliness and damage
prevention when using vacuum components.
Set-Up Configuration
The transmitter may be mounted in any orientation. A horizontal to upright orientation is to
be preffered, to keep condensates and particles from getting into the measuring chamber.
Connection
➡ Remove the protective cover. The protective cover is required during maintenance work.
➡ Make vacuum connection via small flange DN 16KF with version PT R33 130 or DN 16 CF with
version PT R33 330.
WARNING
Where excess pressure is involved in the vacuum system > 1 bar:
Inadvertent opening of elements under stress can lead to parts flying around.
➡ Only use stressed elements which can be opened and closed (for example strap
retainer-tension ring).
WARNING
With excess pressure in the vacuum system of 1.5 to 4 bar:
With KF flange connections elastomer washers (for example O-rings) cannot
withstand the pressure and this can lead to personal injury resulting from the
emission of process media.
➡ Use sealing rings with an outer centering ring.
6
3.3. Electrical Connection
CAUTION
Only connect/disconnect the cable to/from the transmitter when it is off
circuit.
➡ First make the connection to the controller DPG 101 by means of Data Cable, Type PT 348 2xxT (please see "Accessories") on the RS 232 Serial Interface of the controller.
➡ Then connect the power supply 24V DC.
➡ Set transmitter with the address switch S on the rating plate side to RS 232 operations
(basic setting ex-works).
Set address switch
Berliner Strasse 43
----------------------------------
S
With controller, Type DPG 109:
Up to nine transmitters in series can be connected to this controller.
➡ Integrate the transmitter with Data Cable Type PT 348 4xx-T (please see "Accessories") into
the measuring chain.
➡ Set the transmitter with the address switch on the rating plate side to RS 485 operations with
an appropriate address (please also refer to Operating Instructions DPG 109).
➡ To connect a transmitter to a PC, use the Power Pack DPS 101 and set the
transmitter to RS 232.
7
Alternative
➡ The connection of one or several transmitters to a PC can be effected via the RS 232 output
on the controller DPG 109 or via the Switching Power Pack DPS 109 with
integrated PC adapter.
➡ In this case set the transmitter to RS 485 with the appropriate address.

the necessary protection measures.
CAUTION
Dirt and damage have an adverse effect on the function of these vacuum
components.
➡ Please take account of the instructions with regard to cleanliness and damage prevention
when using vacuum components.
➡ Shut down transmitter head.
➡ Disconnect the connecting cable.
➡ Detach the transmitter heads from the vacuum apparatus.
➡ Place the protective cover in position.

4. Operations
4.1. General
Once voltage has been supplied the transmitter is ready to operate. A stabilization time of 5-10
minutes must be considered of. It is usually better to ensure that the transmitter remains in
operation all the time.
The pressure measured is independent of the type of gas. For matching to various types of gas a
respective gas correction factor can be set; this generates the correct measurement value in the
pressure range below 1 mbar. The gas type correction factor for air and N2 has been set in the
works to 1.00 (please also refer to Section 7.3.”Gas Correction Factor”).
The transmitter has been adjusted in the works. Re-adjustment can be necessary in the event of
extreme temperatures or ageing etc. and is carried out with a connected transmitter via the PCSoftware "DokuStar" or customer specific in accordance with the communication
instructions.
Communication is effected, depending on the position of the address switch on the rating plate
side, via Serial Interface RS 232 or via the RS 485 with one of the transmitter addresses settable
from 1-15.
The transmitter responds to measurement value queries, type queries and setting commands, in
addition it is possible to query and set the gas type correction factor.
4.2. Communication
The transmitter communicates via the serial interface with the respective display units (please
see "Accessories"), but alternatively can also be controlled directly via the RS 232 or RS 485 by
means of the Protocol (1).
The following framework conditions apply: 9600 baud,
8 data bits, 1 stop bit, no parity. The transmitter functions can be operated via the parameters in
the following table:

Data Format u_expo_new
Pressure value as the value to be queried and also as equalization (see below) are transmitted
by means of a string in the format "aaaabb" whereby aaaa is the mantissa and bb the exponent
(number 1 for minus, 2 for plus) 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 1.042x10+3 mbar, "750015"
represents 7.500x10-5 mbar.
Reading Error Codes
Parameter 303 contains the actual error code of the transmitter. The following error codes exist:

4.3. Transmitter Equalization
Operations via display unit DPG 101 or DPG 109:
➡ Equalization of the transmitter as described in section 4.4. or 4.5. of the DPG instructions.
Communication via RS 232 or RS 485:
➡ Evacuate the vacuum system to the pressure of p<1x10-5 mbar.
➡ Set the adjusting pressure point [P:741] to «000» for low pressure and transmit.
➡ Transmit the actual pressure
value ([P:740] with «000000» ) for low pressure
-5
(represents p < 1,0 • 10 ); ==> ‘’ur’’ (under Range).
➡ Vent to atmospheric pressure with air or N2; afterwards wait about 10 minutes.
➡ Set the adjusting pressure point [P:741] to «001» for high pressure and transmit.
➡ Set the actual pressure value to the atmospheric pressure ( «100023» for
1000 mbar).
