Operation modes of the switching outputs
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.

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 switching point and the release point have to be defined separately.
If SP.1 changes, 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.

Operating modes
RUN-Mode
Normal operating mode
At power on the unit is in the Run mode. It carries out its measurement and evaluation
functions and provides output signals according to the set parameters.
The display shows the current system pressure. The yellow LED indicates the switching
state of the output.
Display mode
Indication of parameters and the set parameter value.
When the Enter/Set button is pressed briefly, the unit passes to the Display mode which
allows parameter values to be read. The internal sensing, processing and output func-
tions of the unit continue as if in Run mode.
The parameter values can be read and adjusted.
Pressing the arrow key „downwards“ briefly, scrolls through the adjustable parameters.
Pressing the Enter/Set button briefly, indicates the adjusted parameter value.
Pressing the arrow key „downwards“ or „upwards“ briefly, changes the parameter value
step by step. Pressing the arrow key continuous changes the value fast.
Pressing the Enter/Set button safes the adjusted value, the Display blinks three times.
The unit now operates with the „new adjusted“ value.
Returning to the RUN-Mode: Press the ESC button.
Enhanced menu/ Programmimg mode
Setting of the parameter values and programming the main functions.
The unit changes to the programming mode if „EF“ is set in the main menu and the En-
ter/Set button is pressed for at least 5s.
The internal sensing, processing and output functions of the unit continue as if in Run
mode.
Pressing the arrow key „downwards“briefly, scrolls through the adjustable parameters.
Pressing the Enter/Set button briefly, indicates the adjusted parameter value
Pressing the arrow key „downwards“ or „upwards“ briefly, changes the parameter value
step by step. Pressing the arrow key continuous changes the value fast.
Pressing the Enter/Set button safes the adjusted value, the Display blinks three times.
The unit now operates with the „new adjusted“ value.
Returning to the RUN-Mode: Press the ESC button several times.

Press Enter/Set button for 5s, then test-function (no Timeout)
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. VK205A21), 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.
Stellen Sie vor Ein- und Ausbau des Sensors sicher, dass die Anlage druckfrei ist.
Mount the pressure sensor DW35 on a G1/4 – process connection.
Mount the pressure sensor DW36 on a G1/8 – 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 a sharp object.
This causes irreparable damage to the partition!
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.
The device shall be supplied from an isolating source and protected by an overcur-
rent device. Disconnect power before connecting the unit as follows:
