Electrical Installation; Service And Maintenance - Kongskilde Rf20S Gebrauchsanweisung

Electrical installation:

Check that the on-site electrical supply matches the
specifications for the motor. All local factory inspector-
ate regulations must be complied with.
Power connection must be carried out by an authorised
electrician, and the motor must be protected against
overloading by a motor protection device. There must
be a separate main switch that can be locked with a
key.
NB - Most Kongskilde products are designed for either
50Hz or 60Hz operation, it is therefore important to
connect to the correct frequency.
If a 50Hz product is connected to 60Hz, the rpm will be
too high, with the risk of breakdown and personal injury.
Conversely, a 60Hz product connected in 50Hz will not
be able to achieve maximum performance.
The direction of rotation of the rotor is indicated by an
arrow on the rotary valve. If the direction of rotation is
incorrect, the capacity is reduced, and the motor may
be overloaded.
When connecting the motor, do the following:
1. Remove the terminal box cover and connect the
motor according to below.
2. Connect the power and check the direction of rota-
tion on the rotary valve.
3. If the direction of rotation is correct, refit the termi-
nal box cover. If not, swap the connection between
2 phases, check rotation, and refit the cover.
General notes regarding connection of 3 phase
asynchronous motors
If the power lines with phase sequences L2, L1 and
L3 are connected to the connection points U1, V1 and
W1 as shown below, the motor rotates anticlockwise,
viewed from the shaft end. The direction of rotation can
be changed by switching between 2 phases.
Star connection
The earthing terminal on the motor casing is intended
for potential equation, and does not replace the ground
terminal in the connection box.
Remember to connect the motor with sufficient cable to
allow the motor to be removed without disconnecting
the cable.
Start-up:
Prior to start-up, check:
• that there are no foreign objects in the rotary valve
housing or the associated piping system
• that the direction of rotation of the rotary valve's ro-
tor is correct (indicated by the arrow)
• that the rubber ring in the vent screw is removed (if
present)
• whether the rotary valve is securely fastened, in-
cluding also the pipework and any funnel

Service and maintenance:

All service, maintenance and repairs must be carried
out by skilled or instructed person.
Lubrication of the rotor bearings
The bearings are lubricated at the factory and need no
further lubrication.
Gearmotor
The gear unit is filled with synthetic oil at the factory.
Change the oil every 20,000 operating hours or after 4
years of operation at the latest (for synthetic oil). With
mineral oil, the interval is halved.
Oil type can be e.g:
Castrol Alphasyn GS 680
Mobil Glygoyle 680
Shell Omala S4 WE 680
Oil quantity:
Gear for RF 20: 0,1 litres
Gear for RF 40: 0,2 litres
