2. Note
Please read these operating instructions before unpacking and putting the unit
into operation. Follow the instructions precisely as described herein.
The instruction manuals on our website www.kobold.com are always for currently
manufactured version of our products. Due to technical changes, the instruction
manuals available online may not always correspond to the product version you
have purchased. If you need an instruction manual that corresponds to the
purchased product version, you can request it from us free of charge by email
([email protected]) in PDF format, specifying the relevant invoice number and
serial number. If you wish, the operating instructions can also be sent to you by
post in paper form against an applicable postage fee.
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 MAN-LD / MAN-SD 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:
The standard delivery includes:
 Digital Manometer with LCD-Display model: MAN-SD / MAN-LD
 only MAN-SD: 9 V –block battery (IEC 6 LR 61)

4. Regulation Use
The models MAN-LD /MAN-SD are used for the measuring, monitoring and
remote transmission of pressure-dependent operating sequences in machines
and and installations.
These devices are equipped as follows:
 4-digit LCD display
 three programming keys
 process connection made of stainless steel
 limit relays (option)
 peak value memory
 analogue output (option)
 only MAN-SD : power supply by 9 V –block battery
 only MAN-LD : power supply by 24 VDC external
When used in machines, the measuring unit MAN-LD / MAN-SD should be used
only when the machines fulfil the EEC-machine guidelines.
5. Operating Principle
The pressure to be measured is sensed by a ceramic sensor and displayed by
the electronics. As an option, an analogue output signal for remote transmission
of the measured values and a relay output are available.
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. operating temperature of the device is not
exceeded.
 Remove all packing materials and ensure that no such materials remain in the
device.

Flat seal-ring
according to
DIN 16 258
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 according to DIN 16258).
 While threading in the device, install on the hexagonal screw (AF 24) and not
the gauge housing. Only use a wrench for mounting!
 If possible, after the mechanical installation, pressure test the piping to
determine whether the connection joint is adequately sealed.
Attention! The mounting of the device has to be carried out within a
metallic fitting or vessel which must be connected to a potential
equalisation. This action is necessary in order to fulfil the EMV-
guideline.

7. Electrical Connection
Attention!
Incorrect wiring will lead to damage of the unit’s electronics.
7.1 Connection for MAN-LD
 Make sure that the supply wires are de-energized.
 Plug in the system according to the connecting diagrams.
 Power supply conductor (area of cross-section) min. 0.34 mm².

Connection example
The N/O contact is a potential-free relay which
can be operated within its maximum switching
values.

7.2 Connection for MAN-SD
Attention! Please ensure that you use a 9 V – alkali-manganese-
block battery (IEC 6 LR 61).
 Make sure that the supply wires are de-energized.
(Only with option limit contact 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 contact or analogue output.)
 Power supply conductor (area of cross-section) min. 0.34 mm².

9. Adjustment
Possible adjustments of the device:
1. zero point
Prior to commissioning or at regular intervals, the zero point must be set in the
pressureless state, even if the display shows "0". Drifting into the minus range
cannot be ruled out despite the zero display.
Instructions for zero point setting on inside battery cover
2. password (factory pre-set: 5)
3. peak value memory
4. relay (option) with settable hysteresis
5. (factory pre-set: switching point on 50% of measuring range)
Factory pre-sets:
for MAN-LD
1. sampling rate (default: 5 measurements per second)
2. analogue output linear zum Messbereich 4...20 mA (option)
for MAN-SD
1. battery symbol on: voltage under 6,5 V
2. switch-off delay (default: 0 = inactive)
3. sampling rate (default: 5 measurements per second)
4. analogue output (linear) within measuring range 0…2 VDC (option)

If we are in OFF mode regarding the MIN/MAX memory, then the actual pressure
is displayed.
If we are in MIN mode, then the minimum value is displayed with the arrow on the
bottom left.
If we are in MAX mode, then the maximum value is displayed with the arrow on
the top left.
If the peak value memory is activated, the peak value can be reset by pressing
the left arrow key.
Note: With the switch-off of the device the peak value memory
is reset.
