Chair movement testing procedure
The chair does not move at all, even if
the main switch is switched on and the
mains group is working correctly.
Do you hear a “CLICK” sound when you
try to activate the controls?
If no “CLICK” sound is emitted probably
the PCB has failed. Call the servicing
technicians.
Does the motor hum?
The motor may have over-heated and
the thermal security switch may have
turned on. Wait for about 15 minutes, al-
lowing the motor to cool down and oper-
ate the motor again. If the chair does not
move or the motor overheats immedi-
ately after, call the servicing technicians.
It is impossible to determine the cause of
the failure unless further and more com-
plex testing is applied. Call the servicing
technicians.
Chair programming control procedure
The chair moves properly in all manual
movements, but it is impossible to store
working position programs.
Was
the
programming
procedure
properly applied, as explained in para-
graph 7.1.2?
Apply the procedure as quoted in para-
graph 7.1.2.
Did you hear a “BEEP” sound when the
programming procedure was completed,
to confirm the
programs’ saving?
It is impossible to determine the cause of
the failure unless further and more com-
plex tests are performed. Call the techni-
cal service.
The PCB has probably failed. Call the
technical service.
NOTE.
If the foot control display shows an error message (
“ERR” followed by a number code), contact the technical assis-
tance, referencing the visualised code.
