Of a maximum of 9 connected transmitters only a mximum of 4 HPT 100-
Transmitters can be operated on the DPG 109. Otherwise the transmitter types
can be combined as required.
All products in use must be operated in accodance with the respective operating instructions.
Improper Use
The following is regarded as improper:
– The use for purposes not covered above, in particular:
– the connection to components which is not permitted according to their operating
instructions;
– the connection to components which contain touchable, voltage carrying parts.
No liability will be accepted for claims arising from improper use.
The user bears the responsibility with respect to the process media.

3.1. Preparations For Installation
Do not carry out any unauthorized conversions or modifications on the unit.
Before connecting to local mains power:
The voltage stated on the rating plate of the DPG 109 must comply with local
mains voltage values.
Only use this controller where the:
Temperature is in the range: +5°C - +40°C.
Relative humidity is in the range: 5 - 85%, non dew forming.
Atmospheric pressure is in the range: 86 kPa - 106 kPa
3.2. Connections
The mains plug may only be plugged into a socket with protective contacts.
Use only 3 pole mains cable with proper protective earth connection. The
protective earthing may not be replaced by an extension lead without
protective earthing. The mains cable should be connected before all other
cables in order to ensure continuous earthing.
CAUTION
WARNING
If the unit is to be fitted into a rack, mains voltage must be
supplied via a terminal box.

4.1. First-Time Operations
Before switching on it must be ensured that the operating voltage which has
been set on the unit complies with local mains voltage and also that the protec-
tion lead connection has been made.
Check that the unit is earthed and also for correct installation of connecting
lines and transmitter.
The connected transmitter requires a warm up phase of at least 5 minutes.
Before the transmitter is equalized do not subject it to larges pressure
fluctuations.
☞
PLEASE NOTE
CAUTION
The DPG 109 carries out a self-test:
- The software version number
appears in the display.
- The connected total pressure trans-
mitter is identified automatically.
- Before the final switch off, the
actual parameters are activated.
- The start menu "PRESSURE" with
representation of the actual pressu-
re value appears in the display.
Switching off:
The DPG 109 can be switched off in any
operations mode.
The keyboard lock is activated (indicated
with a lock sign) until the DPG 109 is swit-
ched off.

the unit and the setting of the 8 switching
relays are displayed.
»CHANNEL MENU«
This menu shows specific data for the selec-
ted channel (transmitter type, gas type and
correction factor).
In addition there is also the function to
select »adjust« for the respective sensors .
4.3. Measuring Mode
In the measuring mode the DPG 109 shows the currently measured pressure of the transmitter
which is connected. Depending on the pressure range, the display is represented either
numerically or exponentially.
The switch outputs are controlled according to the set switching parameters and actual pres-
sure.
A flashing pressure display or a flashing type display means that the communication with the
transmitter has been interrupted. In such a case re-initialize the unit by renewed depression
of the menu key.
4.4. Configuration Mode (Overview of Menu Options)
The configuration mode on the DPG 10 is attained via the menu key. There, the following para-

(see section 4.4.)
“Up/Down“ keys:
Alters the configuration data; a
flashing cursor marks the
current input position.
“set“ key:

Causes:
1) No transmitter is connected.
2) The address selection switch of the
transmitter has not been set on a 485
Address between 1 and 9..
3) The data line between the DPG 109 and
transmitter is not correctly connected or
is faulty.
4) The unit serial interface in the DPG 109 is
defective.
»ur/or«:
The measured pressure is outside the
measurement range of the transmitter.
»Err1«:
The connected transmitter is defective.
»< 11..00··1100--44«:
With this display the filament is switched off
with the HPT and/or the KK sensor with the
MPT.
The measured pressure with the Pirani
sensor is currently < 1.0 · 10-4 (“UR” of the

Gas Type Correction Factor «CHANNEL MENU«
On total pressure transmitters (PPT 100, RPT 100) which employ a measuring method which is
independent of the type of gas, oonneecorrection factor for matching to various gases can be
assigned to the transmitter. This will ensure that the pressure display is corrected in a broad
pressure range. On a combi-transmitter such as the HPT 100 and the MPT 100 with differing
measurement methods ttwwoocorrection factors are necessary (see the operating instructions
for the transmitter).

Retro-Adjustment «CHANNEL MENU«
With the help of the DPG 109 retro-adjustment can be carried out on the transmitter.
When carrying out a zero point equalization ensure that the pressure in the vacuum chamber
is at least one decade below the measuring range of the transmitter.
The connected transmitter
requires a warm up phase of at
least 5 minutes. Do not subject
the transmitter to large pressu-
re fluctuations before
equalization.
➡Depress “set“ key until the cursor flashes
in the menu point »adjust«.
➡Depress the “Up“-key; in the display
there appears on the cursor position the
display »HI«.
To equalize the transmitter to
the daily pressure ensure that
the pressure on the transmitter
is between 800 and 1200 mbar.
➡After depressing the “set” key there
appears in the display the pre-set
reference pressure value (*)/(**).
➡With the “Up-/Down“ keys set the actual
reference day pressure (**).
➡By depressing the “set“ key the new
value is taken up, indicated through
»OK«, and the cursor jumps back to the
actual channel number »ch:«.
Appears »not OK« in the display, the
transmitter could not be adjusted.
➡Set the reference pressure value in the
same way for the zero point equalization
»LO«.
When equalizing to the zero
point »LO« ensure that the
reference pressure in the
vacuum chamber is at least
one decade below the measu-
ring range of the transmitter.
