2.2 Intended use
The application range of the DS200 is for example:Fan control in air conditioning systems,
pressure or lter control in rooms. As analogue output the operator can use a signal from
0...10 V DC.The output signal proceeds proportional to the measured pressure.
2.3 Functional description
A soft silicone diaphragm is used as sensor. Under the inuence of the differential pressure
the membrane displaces against a measuring spring until spring force compensates the
pressure charging on the diaphragm. A contactless differential transformer and suitable
electronics convert this displacement into a continuously variable output voltage signal.
The DS200 has four calibrated measuring ranges, which can be selected via the software
menu. A two-line alphanumeric LCD display shows the measured pressure in the physical
unit.
In combination with a differential pressure transducer (orice plate, venturi or pitot tube),
the DS200 also directly display the ow in a pipeline. For this purpose, the differential pres-
sure of the transducer is square root and multiplied by an adjustable factor of the transducer.
A damping of output signal because of uctuating measured values, can be adjusted in four
stages via DIP switches.
The differential pressure sensor DS200 delivers an analogue output signal of 0/2...10 V or
0/4...20 mA.The supply voltage is 17...30 Vdc or 24 Vac.

5.5 Function alarm output
The DS200 has an open collector alarm output.
When an alarm occurs, an exclamation mark (!) indicates the alarm state (2nd line / 16th
character).
The open collector output has two different states:
• Highly resistive to disable external circuit
• Low-resistance, to connect an external circuit with maximum load of 30Vdc / 30 mA
For limit value monitoring,a limit value can be entered under the menu item “limit switch”.
The previously set parameters are taken into account (unit, measured variable,k-factor and
the measuring range). In the basic state, the limit values are not active, and the menu item
“limit switch” shows “OFF” in the second line.

Doc.-no.: DS200_01_EN Issue: 05/2017
OPERATION
The output is subject to the following logic with regard to hysteresis and the set
switching delay time:
MAX
switching
logic:
Alarm ON, low resistance
• if ΔP > limit value for set switching delay time
Alarm OFF, high resistance
• if ΔP < 0,95 x limit value for set switching delay time
MIN
switching
logic:
Alarm ON, low resistance
• if ΔP < limit value for set switching delay time
Alarm OFF, high resistance
• if ΔP > 1,05 x limit value for set switching delay time
Three menu items, which inuence the switching behavior of the open collector
output, follow the „limit switch“ menu item:
1. “alarm delay time” with this menu item the switching delay time can be set.The
setting range is 1...60 s or 2...15 min. In the basic state, this value is set to 10 seconds
2.“switching logic” here you have the possibility to set the limit values to MAX or
MIN.At MAX, an alarm is triggered,when the measured value exceeds the limit value;
at MIN, the alarm is triggered when the limit value is exceeded.
3.“Contact logic” the rest state or the switching state of the open collector output
can be set differently.“Active high” means that when an alarm occurs, the open col-
lector output becomes low-impedance.“Active low” means that the alarm switches
the open collector output high-impedance
The following switching pattern can be summarized:
