2 General
2.1 Preface
Please read these Operating Instructions before commissioning the instrument.
Keep the instructions in a place which is accessible to all users at all times.
Please assist us to improve these operating instructions, where necessary.
Your suggestions will be welcome.
All the necessary settings are described in this manual. However, if
any difficulties should still arise during commissioning, you are
asked not to carry out any unauthorized manipulations on the unit.
You could endanger your rights under the instrument warranty!
Please contact the nearest subsidiary or the head office in such a
case.
When returning modules, assemblies or components, the
regulations to EN 100 015 “Protection of electrostatically sensitive
components” must be observed. Use only the appropriate ESD
packaging for transport.
Please note that we cannot accept any liability for damage caused
by ESD (electrostatic discharge).

2.2 Application
General note Pressure and differential pressure transmitters Type 404304 are used for mea-
suring very low pressures.
Corresponding to the measuring range, the CuBe diaphragm inside
the instrument is very sensitive.
Do not blow into the pressure connections, as this may
damage or destroy the instrument.
The instrument is suitable for non-corrosive gases only.
The instrument has no Ex approval.

4 Mounting
Fixing ✱Use the lugs to fix the instrument.
The instrument should preferably be fixed vertically (pressure
connections below), since it has been factory-calibrated in this posi-
tion.
This ensures that no condensate from the pressure lines will enter
the measuring system.
Do not install the instrument close to sources of interference (trans-
formers, transmitters, motors) or heat sources.
Shock or vibration will lead to measurement errors.

5.1 Electrical connection
Opening the
instrument
✱Unscrew the four slotted screws
✱Remove cover
Connection
When connecting the instrument, please observe the VDE regulati-
ons concerning work with mains supply voltage, as well as the
regulations of the trade insurance associations regarding work on
and with electrical equipment and installations.
Never connect the supply voltage to the output terminals!
For the required supply voltage, see nameplate.
Instruments with DC supply have a reverse polarity protection.

6 Commissioning
After
connecting the
supply voltage
The output signal can be measured after the supply voltage has been con-
nected.
For gauge pressure measurement, connect the pressure to be
measured to the “+” input. The other pressure connection remains
open.
The warm-up time for the instrument is 1hour.
After this time (at a constant ambient temperature), the output sig-
nal with differential pressure measurement must have stabilized at
zero.
With short ranges, the mounting position can cause a zero shift.
This shift can be compensated after the warm-up time by using the
potentiometer TP1 (zero).

Required aids • pressure generator
• reference pressure measuring device
• supply for pressure /differential pressure transmitter
• voltmeter/ammeter (multimeter)

Calibrating ✱Open instrument, see "Opening the instrument", page 11.
✱Connect voltage supply, see "Connection", page 11ff.
✱Connect multimeter, see "Connection", page 11ff.
✱Wait for instrument to warm up (approx. 1 hour).
✱Set zero:
With open pressure connections, set display value of multimeter to 0 V
(with current output to 0(4) mA) by using the potentiometer TP1.
✱Set nominal pressure:
Apply nominal pressure to instrument at the “+” pressure connection.
Using the potentiometer TP2, set display value of multimeter to 10 V
(to 20 mA with current output).
Only adjust the instrument potentiometers listed in the instructions
below! The other potentiometers are factory-set and must not be
adjusted!

8 Setting the limit contacts
Preparation ✱Open the instrument, see "Opening the instrument", page 11.
✱Connect voltage supply, see "Connection", page 11ff.
✱Connect multimeter, see "Connection", page 11ff.
✱Wait for instrument to warm up (approx. 1hour).
Defining the
switching range
(only for "+/-"
ranges)
✱Use jumper J1 (for GK1) or J2 (for GK2) to determine whether the limit
contact switches in the positive or the negative pressure range. For jumper
functions, see table above.
Setting the
relay function
✱Use jumper J3 (for GK1) or J4 (for GK2) to determine whether the relay
switches as max. limit contact (relay switches when the actual value is
larger than the setpoint) or as min. limit contact (relay switches when the
actual value is smaller than the setpoint). For jumper functions, see table
above.
Setting the limit
contact with a
reference
pressure mea-
suring device
✱Set switch-on and switch-off delay to 0 (turn fully to the left) by using the
potentiometer TP3/7 or TP4/8.
✱Apply the pressure at which the limit contact has to switch to the pressure
transmitter.
✱Keep on adjusting the potentiometer TP1 (for GK1) or TP5 (for GK2), until
LED GK1 or GK2 lights up.
✱Apply the pressure at which the limit contact has to switch back to the pres-
sure transmitter.
✱Keep on adjusting the potentiometer TP2 (for GK1) or TP6 (for GK2), until
the LED GK1 or GK2 goes dark.

Example 1: measuring range 0 to 3 hPa,
switching point at 1.5 hPA (50%) => 0.5 V
Example 2: measuring range -2 to +8 hPa,
switching point at +3.5 hPA (55%) => 0.55 V

Example: limit = 0.5 V,
hysteresis = 10% => 0.45 V

8 Setting the limit contacts
Setting the
limit contact
by using a
multimeter
✱Connect multimeter to connector ST4 (for GK1) or ST5 (for GK2), see table
above.
✱Set switch-on and switch-off delay to 0 (turn fully to the left) by using the
potentiometer TP3 (for GK1) or TP7 (for GK2) (switch-on delay) and TP4 or
TP8 (switch-off delay).
✱Set the voltage that corresponds to the switching point by means of the
potentiometer TP1 (for GK1) or TP5 (for GK2).
Example: range 0 to +3 hPa; desired switching point 1.8 hPa => 60 % of
range; the corresponding voltage at the connector ST4 or ST5 is 0.6 V
Setting the swit-
ching
hysteresis
by using a
multimeter
✱Connect multimeter to connector ST4 (for GK1) or ST5 (for GK2), see table
above.
✱Set switch-on delay and switch-off delay to 0 (turn fully to the left) by using
the potentiometer TP3 (for GK1) or TP7 (for GK2) (switch-on delay) and TP4
or TP8 (switch-off delay).
✱Using the potentiometer TP2 (for GK1) or TP6 (for GK2), set the voltage that
corresponds to the hysteresis.
Example: switching point at 0.5 V; desired hysteresis 10 %; corresponding
voltage at the connector ST4 or ST5 is 0.45 V
Setting the
switch-on or
switch-off delay
✱Set the switch-on delay using the potentiometer TP3 for GK1 or TP6 for
GK2 within the range 0 to 10 sec.
✱Set the switch-off delay with the potentiometer TP4 for GK1 or TP8 for GK2
within the range 0 to 10 sec.
The range 0—100% always corresponds to 0 to 1 V, e.g.:
pressure range 0 to +3 hPa corresponds to 0 to 1 V
pressure range -3 to +3 hPa corresponds to -0.5 to +0.5 V
pressure range -2 to +8 hPa corresponds to -0.2 to +0.8 V
