Warning Notes - Kongskilde Rf20S Gebrauchsanweisung

GB
This user manual applies to the Kongskilde RF20R /
RF40 rotary valves.
The target group for this manual are operators, (elec-
trical) installers as well as maintenance- and service
staff.
Description:
The rotary valves are suitable for the introduction of
granulated materials such as plastic granules and
other small items, in connection with pneumatic con-
veying systems. The rotary valve will ensure minimal
pressure loss and optimal energy utilisation.
The rotor of the rotary valve is driven by an electric
geared motor. The rotor is mounted at each end of the
rotor shaft and the motor gear is mounted on the rotor
shaft.
The rotary valve can be mounted on vertical OK200
outlets, and horizontal OK160 connections. The rotary
valves are not approved for outdoor installation.
The rotor is fitted with replaceable paddles, which
should be replaced when the pressure loss has be-
come too great.
The temperature of the material and conveying air
must not exceed 70°C.
The rotary valve is not intended for corrosive or erosive
gases and materials. Similarly, highly abrasive materi-
als will reduce the service life of the sealing plates in
particular.
The rotary valve must not be pressure washed or
otherwise cleaned with water, as this will damage the
rotor bearings.

Warning notes:

Avoid accidents by always following the safety instruc-
tions indicated in the manual and on the rotary valve.
The rotary valve must be installed in a closed pipework
system, without access for persons to rotating parts.
There is a risk of breakage and damage to the rotary
valve, if foreign objects of a certain size are caught/
dropped into the system. Lack of supervision of the
rotary valve can lead to wear and tear, energy loss and
breakage of vital parts, see the "Service and mainte-
nance" section.
Due to frictional heat, the outer casing of the rotary
valve will be hot.
The installation and fastening must be carried out in
accordance with section "Installation", otherwise stabil-
ity may be impaired and wear may increase.
Ensure that all pipework is in order and correctly fitted
during operation.

Always disconnect power to the rotary valve be-
fore repair and maintenance. The main switch must
be disconnected and locked so that the rotary
valve cannot be started by mistake.
The rotary valve contains rotating parts that a person
must not come into contact with in any way, unless the
main switch is disconnected and locked with a padlock,
or the rotary valve is without power cables. If a per-
son comes into contact with the rotating parts (where
they are in motion), there is a VERY high risk of injury.
Therefore, never reach into the inlet or outlet of the
rotary valve while it is running!
If it is necessary to remove material that has stopped
the rotary valve, switch off and lock the main switch
to prevent unintentional start of the rotary valve. If the
blockage is removed, while power is on, the rotary
valve will start when the the blockage is removed. This
poses a high risk of serious personal injury!
To prevent accidental contact with the rotating parts,
a minimum of 850 mm long pipes (max. Ø200 mm)
MUST be fitted (max. Ø200 mm) on inlet and outlet
piping. These pipes must be installed with bolt clamps,
where tools are necessary for dismantling.
In case it is not possible to use minimum 850 mm
pipes, it must be insured that there within minimum
850 mm from the rotary valve are used bolt clamps,
where tools are necessary for dismantling.
The reason for this is, that according to EU-directive
2006/42/EC (Machinery Directive), it is not allowed for
any unauthorized personnel to gain access to rotat-
ing parts. In case quick clamps are used, unautorized
personnel could dismantle the piping, and gain access
to rotating parts.
Prevent foreign objects from being sucked into the
connected pipework - any metal object can cause
sparks inside the rotary valve, with the risk of a dust
explosion. Similarly, avoid flames or sparks from e.g.
an angle grinder being sucked into the pipework.
Ensure that there are safe access routes that can be
used for repair and maintenance of the rotary valve.
Keep the workplace tidy so that there is no risk of fall-
ing accidents.
Ensure sufficient lighting conditions for safe operation
of the rotary valve.
If abnormal vibrations or noise are detected, stop the
rotary valve immediately and investigate the cause.
If there is any doubt, seek professional assistance for
possible repair and maintenance.
Beware of eye injuries. If there are small particles in
the material being transported, they can be blown
out through the outlet together with the conveying air.
Therefore, wear protective goggles near the outlet.
