GENERAL SAFETY INSTRUCTIONS
1. General safety instructions
1.1 Signal words for safety instructions
The safety instructions in this operation manual are designed to prevent hazards.They can
be found in the operation manual before an operation / task / activity is described, which
can entail a possible hazard.
Identication of a hazard with a low risk, which can lead to material
damage or minor or moderate bodily injuries.
CAUTION
1.2 Used pictograms and symbols
In this manual the following symbols are used:
General hazard symbol (dan-
ger, warning, caution)
2. Product description
The differential pressure controller DPC200 measures low pressure of non-aggressive
gases, particularly of air.

2.1 Type plate
2.2 Intended use
The range of application of the device is e.g. in air conditioning systems for fan control,
for pressure control in rooms or lter control. As analogue output the operator can use
a signal from 0 ...10 V DC. Depending on the settings the device the signal has different
meanings:
1. Is the device is used as a pressure sensor, the output signal proceeds proportional to
the measured pressure.
2. As a volume ow sensor the device offers a square root signal.
3. With pressure resp. volume ow regulation the output signal stands for the control
variable of the PI-control.
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 DPC200 combines different functions:
1. On the one hand it is used as a measuring device. In the measuring mode the differ-
ential pressure is shown on the display, and it is given as a proportional 0...10 V DC
output signal.
2. Besides the measuring mode the DPC200 also can be operated in a control mode.
Two setpoints can be adjusted in the device and can be selected with the potential free
contact input. The PI-Algorithm settles the measured differential pressure with the
setpoint and operates the actuating variable so that a constant pressure results accord-
ing to the setpoints is set.The control variable is given as a 0...10V DC output signal.
Besides the quantity ‘differential pressure’ also the quantity ‘volume ow’ can be used for
measuring and for regulation.

INSTALLATION
3. Installation
The differential pressure controller DPC200 is designed for wall mounting.
When selecting the installation site please note the following factors:
• The mounting surface must be solid enough and vibration-free.
• The environment has to full the ambient climatic conditions as given in the technical
data.
Material damage
Read the manual carefully before installation and operation
Only experienced stuff may connect the device and bring it into
operation.
CAUTION
• The device is position depended.
• It is important that the assembly is vertical.
• The DPC200 can be mounted on a wall.
NOTICE
3.1 Dimensions

5.6 Function alarm output
The DPC200 has an open collector alarm output; depending on the operating mode the
function is different.
At the alarm event a contact between terminal no. 7 and no. 8 gets low-resistive and
can be loaded with a maximum of 30 V DC/ 30 mA.When the alarm is switched off the
contact will be high-resistive.
During alarm state in the control mode / measuring mode an exclamation point is displayed
(2nd line / 16th character).
Control mode:
In order to recognize the limits of control, the alarm output in the control mode refers to
the set maximum output voltage (MaxUout). MaxUout can be set in the menu item „output
voltage“.
In the default setting the value is set to 10V DC.
Alarm ON: Output voltage for 12 seconds constantly greater than: 0.95 • MaxUout
Alarm OFF: Output voltage for 12 seconds constantly less than: 0.9 • MaxUout
Measuring mode:
For limit value monitoring a limit value can be entered.This value is set in the menu item
„limit switch“. The previously set parameters are taken into account (unit, parameter,
k-factor and the measuring range).
In the default setting the limits are not active. Display 2nd line: „OFF“
Alarm ON: Measurement for 12 seconds constantly greater than 1 • limit value
Alarm OFF: Measurement for 12 seconds constantly less than 0.95 • limit value
