notes:
•The following examples and descriptions of the switching output 1 (SP1) refer to the
switching function „normally open“ (no). If the switching output 1 is set „normally
closed“ (nc) the states are reversed.
•The minimum range between the switching outputs (SP.1 and rSP.1) is 1% of the
nominal pressure; stated by the system.
•The smallest adjustable hysteresis is 1% of the nominal pressure; stated by the sys-
tem.
•All examples are effective for output 2, if this output is defined as switching output
(SP-2) also.

output
output
switch-point with release position
programmed parameters: SP.1: 250.0 bar
rP.1: 40.0 bar
An increasing pressure up to SP.1 (e.g. 250bar), switches the output according to the ad-
justed switching function (no or nc). This state remains also for higher pressure.
For decreasing pressure the switching state changes with the pressure value at rP.1 (e.g.
40bar). If SP.1 will be changed, rP.1 remains the same.
The minimum range between SP1 and rSP.1 is 1% of the maximum pressure.
switch-point with hysteresis
programmed parameters: SP.1: 50.0 bar
HYS.1: 20.0 bar
An increasing pressure up to SP.1 (e.g. 50bar) switches the output according to the ad-
justed switching function (no or nc). This state remains also for higher pressure.
For decreasing pressure the switching state changes after passing the hysteresis (e.g.
20bar). If SP.1 will be changed, the hysteresis HYS1 remains the same, that is the release
position is (SP.1 – 20)bar.

window function with release position
programmed parameters: SP.1: 250.0 bar
rP.1: 40.0 bar
Due to the window function, the monitoring of a defined pressure range is possible.
As soon as the pressure reaches the adjusted range between rP.1 (40bar) and SP.1
(250bar), the output switches according the chosen switching function (no or nc).
The switching state changes if the pressure leaves the adjusted pressure range.
The values for the switch-point and the release position have to be defined separately.
If only SP.1 is changed, rP.1 will remain the same.
window function with hysteresis
programmed parameters: SP.1: 50.0 bar
HYS.1: 20.0 bar
If the pressure hits the adjusted window between (SP.1-HYS.1) and SP.1 (50bar), the
output switches according to the adjusted switching function (no or nc). The switching
function changes when leaving the window. If SP.1 changes, the hysteresis will not
change, e.g. the release position is (SP.1 – 20)bar.

With the Test-function you can check the adjusted parameters
without influence for the system.
The display starts with indicating the current pressure.
Due to the arrow keys the displayed value can be increased or
decreased. All parameters react as if the real pressure would
increase or decrease.
Leave the Test Mode with ESC.
END End of enhanced functions.
Press the Enter/Set button twice to get into the RUN mode
again.
The units come with an optical interface that allows all parameters to be set and ad-
justed by a PC or notebook.
The suitable interface cable and Windows-Software can be ordered with the article
number AD000011.
With the Software you are able to adjust all functions described above.
NOTE: Use a shielded cable socket (e.g. VK205321), in order to avoid interfer-
ences.
mounting and electrical connection
Before mounting and removing the unit: Make sure that no pressure is applied to the
system.
Mount the pressure sensor DW34 on a G1/2 – process connection.
After mounting the sensor mechanically, the control panel can be rotated by 350°.
Do not touch the opening of the pressure connection with finger or a sharp object.
This causes irreparable damage to the mebrane!
The unit must be connected by a suitably qualified electrician. The national and in-
ternational regulations for the installation of electrical equipment must be observed.
Voltage supply to EN50178.
Disconnect power before connecting the unit as follows:
