2.Note
Please read these operating instructions before unpacking and putting the unit
into operation. Follow the instruction 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.
By usage in machines, the measuring unit should be used only then when the
machines fulfil the EC-machine guidelines.
3.Regulation use
LSP-P
These units (type LSP) are employed in order to monitor the air-flow in air
environment industry. All these units are equipped with adjustable limit-contacts.
Monitoring of fluids is suitable only for those gases and air, which would not
attack the materials used in flow monitor.
This air-flow monitor should not be used for monitoring of flammable and
explosive gases.
Material Combination
HousingGalvanised base-plate
/Cover (ABS)
Paddle St. Steel (AISI)
Paddle arm Brass (Ms 58)
Connection- plate Galvanised iron
Flat Gasket Flexoid
Switch Off/On (adjustable)
Switch-off values (min) 1.5 m / sec.
(max) 8.0 m / sec. (with shortened paddle)
Switch-on values (min) 2.5 m / sec.
(max) 9.2 m / sec. (with shortened paddle)
and
4.Operating Principle
The air flow being controlled presses against the paddle, which is mechanically
linked to a dust-tight changeover microswitch. The latter will signal whether or not
the minimum or maximum preset air flow exists.
The switching point is adjustable over a wide range of values.

5.Instrument Inspection
Instruments are checked before dispatch and should arrive in perfect condition.
In case of damage, please inform your local Kobold office or if you had the parcel
transport your parcel service / forwarding agent immediately, since they are
responsible for damages during transit. Should the damage to a device be visible,
we recommend a thorough inspection of the delivery packing.
Scope of delivery:
• Air-Flow Monitor Model: LSP-P
• Flat Gasket
• Operating Instructions
6.Mechanical connection
Before mounting
Please ensure that the actual flow value remains within the switching range of
the unit.
Make sure that the permitted max. operational pressure and temperature limits
of this unit are not exceeded.
Please ensure a minimum run inner pipe diameter of 5 x D upstream and
downstream of the switch.
Assembly
Drill a hole and a slit in your air-channel as shown in the adjacent
drawing.
Fix the flow-monitor over the air-channel and secure it with 4 metal
screws (D=3.5 mm).
The paddle can also be mounted after the installation, it is
then sufficient to drill a 20 mm diameter hole.
Sealing is carried out by means of supplied flat gasket.
Mounting of this unit is position independent. The affixed arrow sign
on housing must point in the direction of the flow. The upper part of
the flow-monitor must be vertical with respect to the pipe axis.
With vertical mounting, the switching point must be adjusted in
order to compensate for the paddle-weight.
For gases containing dust particles, the flow monitor must be positioned in
such a way that no dust particles can deposit inside the connection head (e.g.
mounting on the upper side of the air-channel).

7.Electrical Connection
Please ensure that the voltage as well as the current
values of your power supply does not exceed the
permitted values specified for the flow monitor.
Before making connections, be assured that the
power supply lines are not active.
Remove the housing of the flow monitor by loosening
4 screws
Make connections to the flow monitor as shown in the adjoining figure.
After making connections between external units and the limit-contact, the unit is
ready for operation.

8.Commissioning
These units are supplied along with an adjustable micro-switch. The contact is
hange-over type, which, depending on connections, may be used as normally-
c
closed or normally-open switch.
These units are factory-set at a switch-off value of 1.5 m / sec.
A higher "switch-off" value is set by rotating the range-screw in the clockwise
direction.
In a switching value over 5 m / sec. is desired, then the paddle must be
trimmed at the marked position.
When trimmed, the factory-set value changes to 2.5 m/sec.

11.Maintenance
In case, the medium to be measured is not polluted, LSP-P flow-monitor is
regarded as maintenance-free. Otherwise, presence of large-size dust-particles
may lead to the jamming of paddle arm. Depending upon the degree of pollution,
a routine check after regular intervals is recommended.
