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.

G1/4

AF 24

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.

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.

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.
