Pressure Measurement Amplifier DMV 4000
1. General Description:
The Gneuss pressure measurement amplifier type DMV 4000 is a measurement amplifier for pressure
transducers with strain gauge technology. Universal setting possibilities guarantee that all pressure
transducers with 1 to 4 mV output signal can be connected. Furthermore, three freely-adjustable limit
contacts and one optional analogue signal 0-10 V, 0-20 mA or 4-20 mA can be processed. A peak
hold function, simple operation via a touch sensitive keypad and extreme sturdiness guarantees a high
ease of operation. The unit can be protected against unauthorized use via possible software settings.

3 . Assembly:
The instrument is designed for panel assembly. It is to be assembled in such a manner, as to protect it
from humidity, dirt and vibration. The ambient temperature is not to exceed 50 °C.
4. Commissioning electrical connection:
The instrument is only to be connected and operated by qualified personnel. Please see attached
diagram for wiring connections. The local regulations for operating electrical factory equipment are to
be stringently adhered to.
CE-Mark
For unrestricted operation of the instrument according to the guidelines of the electromagnetic
compatibility 89/336/EEC all analogue wiring needs to be shielded. The shield is to be one sided
UL recommendation: 1) Use copper conductors designed for temperatures up to 60/70 °C
2) Minimum cross-section of 1mm² to be utilized. (AWG 18)
Analogue output:
For an analogue output of 0-10 V, the pre-installed 500Ωresistance is to be used with a set parameter
of 0-20 mA. For all other outputs, the pre-installed 500Ωresistance has to be removed from terminals
19 / 20.

7. Programme accessibility / barring:
7.1 Keypad lock/unlock
The DMV 4000 allows all accessibility levels to be password protected.
To lock/unlock the keypad, press and hold the keys and simultaneously for 2 seconds. With
keypad locked, if the user presses a key, the instrument displays the message „Lock“.
The keypad lock is retained in the event of power failure.
7.2 Output lock/unlock
The analogue and alarm outputs are switched to the OFF status by pressing and holding the keys
and simultaneously for 2 seconds. With the outputs locked, when displaying the process
variables, the instrument displays the message “block” instead of “Unit”. To unlock the outputs press
the keys simultaneously again.
The output lock is retained in the event of power failure.
8. Commissioning
Listed below is a step-by-step breakdown for start-up and commissioning purposes. In order to
warrant an exact measurement, the connected pressure sensor needs to be calibrated in conjunction
with the DMV 4000. During the calibration procedure, the pressure sensor must be at operating
temperature and not subjected to any pressure influences.
1. Confirm no supply voltage.
2. Connect DMV 4000 according to wiring diagram ( page 4 )
3. Connect supply voltage. After approx. 3 seconds the DMV 4000 is ready for operation.

Page 11 of 15
Pressure Measurement Amplifier DMV 4000
Adjustment levels (see Tables on pages 5 and 6).
By repeatedly activating the button the DMV 4000 switches from operating mode to calibration
mode alternatively to Parameter mode (Par) and to configuration mode (Conf). On pushing again
the instrument is set back to operating mode.
Factory setting of passwords see page 7!
To access all levels a password needs to be entered after pushing .This is done by holding
down the buttons and the instrument automatically selects ones, tens, hundreds and
thousands and selectably increases or decreases. By pushing the button the next accessible
level is reached.

Is divided up as follows:
Basic configuration: Adjusting the supply frequency
Input configuration: Adjusting the measuring values, commas and input values
Configuration of analogue outputs: Adjusting the analogue output signals
System configuration: Adjusting the serial communication and passwords
Alarm configuration: Adjusting the Alarm outputs
Sensor calibration configuration: Adjusting the sensor calibration points

Parameter levels (PAR)
Is divided up as follows:
Alarm set-points: Adjusting the separate alarm contacts 1 - 3

9.Additional function:
Peak hold:
During normal operation of the DMV 4000 the internal peak hold can be evaluated and deleted. The
highest and lowest point of the pressure range this function allows pressure spikes to be registered.
After switching on the unit this function is constantly repeated.
Push button: The minimum value is displayed for five seconds
Push button: The maximum value is displayed for five seconds
Push button: all values are deleted and re-set to the original set-point
Measurement resumes until next point of deletion or until the unit is switched
on and off again
Display of measuring values
During normal operation of the instrument the possibility of allowing the measuring value to be
displayed in time intervals is performed by repeatedly pushing the button
Following display and adjustment possibilities are possible

operation ( Yes / No )
Fail safe feature:
The DMV 4000 has a fail-safe feature for the connected pressure sensor. The following signals are
monitored: Signal + pin 8 signal - pin 9, supply voltage + pin 11, Supply voltage – pin 13.
On breakdown of one of the above mentioned signals, or by not connected pressure sensor, the fail
safe feature is displayed with “ Open

Open “ . Additionally all alarm signals are activated. An analogue signal
will then give out a minimal output.
