into operation. Follow the instructions precisely as described herein.
The devices are only to be used, maintained and serviced by persons familiar
with these operating instructions and in accordance with local regulations
applying to Health & Safety and prevention of accidents.
When used in machines, the measuring unit should be used only when the
machines fulfil the EC-machine guidelines.
3.Instrument Inspection
Instruments are inspected before shipping and sent out in perfect condition.
Should damage to a device be visible, we recommend a thorough inspection of
the delivery packaging. In case of damage, please inform your parcel service /
forwarding agent immediately, since they are responsible for damages during
transit.
Scope of delivery:

5.Operating Principle
The differential pressure sensor PMP is used for controlling and measuring the
differential pressure of air or non-corrosive gases. It is mainly used for the
monitoring of filters and filter cartridges.
The devices are equipped as follows:
Differential Pressure Measurement
The differential pressure is shown on a four-digit LED display.
Limit Value Contact
The devices are provided with two programmable relays for monitoring the
differential pressure. Thus, the magnetic valves for the cleaning cycles can be
piloted or used for programming the alarm pressure.
Analogue Output
For a remote transmission, a 4 to 20 mA output signal is provided.

6.Mechanical Connection
Before installation:
Make sure that the max. allowed operating pressures and service
temperatures are not exceeded (see section Technical Information)
Connect your tube to both screw connections.
The over-pressure side is marked with a “+” symbol,
the low-pressure side with a “-“ symbol.
7.Electrical Connection
Make sure that the supply wires are de-energised.
Plug in the system according to the following connecting drawing.
All connecting operations are completed, if the planned external devices are
connected to both limit contacts and to the analogue output.
The device can now be put into operation.
The adjustment of the output signals is described in the following sections.
