Bauer S300 Original Operating Manual page 37

Fault
Solid cake is very hard;
Solid matter comes out slowly
and very dry
Separator is running
The amperemeter indicates
higher values than usual
No discharging of solids
Minimal discharging of liquid
Increased auger and screen
wear
Moisture content of the dis-
charged solid varies greatly
Geared motor of the separator
switches off
The motor switches off when the
permissible power consumption of
the motor has been exceeded.
The setting for the maximum power
consumption applies to operation
under load
Cake ejection The cake
–
has been pushed out
The solid cake breaks up and
liquid emerges from the mouth-
piece
Operating Manual for BAUER Separator S300
Cause
1. The leverage of the weights is too
great, meaning that the contact
pressure of the output regulator is
too high.
2. The supply medium has changed
or the supply line has been
changed.
1. Rotation direction of the separator
reversed
2. Auger channels clogged
Abrasive components in the medium,
such as sand
The separated medium (slurry) has
varying consistency
1. Overload
2. Power consumption is too high
because the solid cake is too hard.
3. The setting for the maximum pow-
er consumption is not configured
correctly or the control unit has
been damaged.
4. Foreign bodies are blocking the
auger
1. The leverage of the weights is too
low.
2. The pump pressure is too high; the
optimal pressure / operation for the
separator is 2 m water column with
a steady feed rate.
3. The incoming concentration of
solids fluctuates greatly. The sepa-
rated medium has too little solid
content
4. Solids are too fine and have no
fibrous structure
Remedy
1. Reduce the leverage; if the contact
force is too high, the screen could
be destroyed.
2. Check the consistency of the sup-
ply medium and check the supply
line for any blockages.
1. Check the electrical connection
2. Check and clean the auger
If possible, allow the abrasive compo-
nents to settle before separation.
Mix and homogenize the medi-
um(slurry) thoroughly.
1. Check the motor protection for
correct setting; set to maximum
value, if necessary.
2. See configuration instructions in
the section Initial Startup.
3. Have the shut-off limit adjusted
again by a qualified electrician ac-
cording to the instructions in the
switch cabinet circuit diagram.
4. Check the inflow to the separator
and remove any foreign bodies;
check the auger and screen
1. Increase the leverage of the
weights
2. Reduce the pump pressure by
lowering the pump capacity or re-
placing the pump.
3. Thoroughly mix and homogenize
the medium (slurry) to produce a
uniform solid cake speed. See
configuration instructions in the
section Initial Startup.
The cake may be ejected if the sol-
id content in the supply medium
decreases significantly.
4. Use a finer screen.
