2. Note

Please read these operating instructions before unpacking and putting the unit
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 EWG-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:

The standard delivery includes:

• Transmitter with display

• Operating Instructions

• 9 Volt – block battery (IEC 6 LR 61)

MAN-SD 03/04 page 3

4. Regulation Use

Any use of the Digital Manometer, model: MAN-SD, which exceeds the
manufacturers specification may invalidate its warranty. Therefore any resulting
damage is not the responsibility of the manufacturer. The user assumes all risk
for such usage.

The model MAN-SD serves to measure, monitor and transmit pressure­dependent operational processes in machines and systems.

These devices are equipped as follows:

• 4-digit LCD display

• Three Programming keys

• Process connection (St. Steel)

• Power Supply via 9V block battery

• Limit relays (option)

• Peak value memory (option)

• Analogue output (option)

5. Operating Principle

A ceramic sensor detects system pressure and sends the signal to evaluation
electronics. The sensor signal is conditioned and sent to the LCD display as a
pressure reading. Parallel to this, an output is provided as analogue signal for the
purpose of transmitting measured pressure.
A programmable relay-output is also available as an option.

6. Mechanical Connection

Before installation:

• Ensure that the max. pressure in your system is within the prescribed range of
the digital manometer. The measuring range can be read from the nameplate
label of the device.

• Make sure that the permitted max. operational temperature of the device is not
exceeded.

• Confirm that there are no fragments of packing material present inside the
pressure sensing port.

Installation:

• Ensure that the piping is fully depressurised..

• The digital manometer should be mounted just like a mechanical manometer.

• With standard thread connection, sealing is achieved by means of a suitable

gasket (flat-seal or seal-ring DIN 16258).

• While threading in the device, install by using a wrench on the hexagonal
screw (SW 24) and not the gauge housing.

• If possible, after the mechanical installation, pressure test the piping to
determine whether the connection joint is adequately sealed.

Attention! The MAN-SD digital manometer must be installed into a
grounded system. This action is necessary in order to fulfil the EMV­guideline.

7. Electrical Connection

Attention! Please ensure that you use a 9 V – alkali-manganese-block
battery (IEC 6 LR 61).

• Make sure that the power supply lines are not active.
(Only with option limit-contacts or analogue output.)

• Open the battery enclosure on the back-side of the unit and connect the 9V
block battery with the connection plug.

• Place the 9V block battery in the enclosure and close it with the lid.

• Terminate the connection wires on the plug (cable), as shown in the illustration

below. (Only with option limit-contacts or analogue output.)

• Power supply conductor (area of cross-section): min.0.34 mm².

Attention! Incorrect wiring will lead to damage of the unit’s electronics.
