Error
Indication
Error Cause
Possible Error
Source
Corrective Procedure
Mains fuse or circuit
breaker failed
Check fuse or circuit breaker and replace or
switch on again
Faulty mains cord or
instrument socket
Check instrument cord and socket, replace
defective parts
No mains
voltage supply
Unit fuse or fuses on
the main board
defective
Replace it, if fuses blows again, search for
other faults
Faulty connection
from CPU to
indication board
Check connectors on CPU, indication board
and connecting leads
No low voltage
supply for
indication board Faulty indication or
CPU board
Replace main board completely
Displays
remain
dark
Interrupted
program
NV-RAM out of
socket or not
correctly placed
Insert the valid NV-RAM and push it correctly
into socket
Reduced voltage
supply (>10%)
Remedy the failure
if the voltage drops often, use a voltage
stabiliser
All
display
elements
are shortly
illuminated
CPU program
reset may be
caused by EMI
Bad or missing
ground connection
Check all ground connections and the ground
connection of all boards
Constant
Interruption
Parameter NV-RAM
No or defective NV-RAM
Wear out of motor
rubber mount
Replace motor rubber mounts (at least every
three years)
Mechanics
Motor bearings
Replace motor completely
Defective terminal
connection, faulty
lead or motor winding
Check voltage on motor terminal and winding
resistances -see test points on boards
Drive makes
noises
-no
good
separation
result
Electrical
Faulty power electr.
Replace main board
Missing mains
voltage
Remedy see above, manual opening cord in
bottom plate
PTC resistor has
released
After a waiting time of 2 minutes press key
again
Lid solenoid is
not sufficiently
supplied with
voltage
Faulty driving or triac
circuit
Replace the complete main board
Faulty lid coil
Faulty winding of coil
Replace complete lid lock device
Lid bolt is jamming
Push lid centrally into lock and press the key
again
Lid
cannot be
opened
by key at
standstill
->“E-17“
Lid is not
correctly locked
Lid is de-adjusted
Re-adjust the lid centrally
Lid was opened
manually during
run
FORBIDDEN!
Forbidden
intervention
emergency opening
device must only be
used at standstill
Close lid immediately
Pull and plug in power cord again, press start
key to continue run, press stop key to finish
run
Lid switches or leads
are interrupted
Check leads and connectors to micro switch,
in case of a faulty micro switch, replace lid lock
device completely
After cooling down check temperature switch
with ohmmeter
Check ventilation (fans) and proper air flow
“Lid“
appears in
speed
display
15V low voltage
supply for
frequency
converter via the
lid switches and
motor over-
temperature
switch is
interrupted
during run
Motor over
temperature switch
has tripped,
blocked air flow to
the motor
only two phases are
controlled to the
motor
Check terminal connection
XM
and motor
windings - approx. 11,5 Ohm between
conductors - replace defective parts
